Additional details on each of these engineering achievements follow:

Multi-Material Body
Acura's First Application of a Multi-Material Body with Space Frame Construction 
Developing the Most Rigid-in-Class, Multi-Material Body

At the core of the NSX mission to deliver timeless sports car values is an aluminum-intensive, multi-material space frame. This innovative space frame represents a next-generation leap in body design with class-leading technology that is exclusive to Acura within the automotive market. Based on internal data, the all-new Acura NSX multi-material body is by far the most rigid in its competitive set.

While the all-aluminum monocoque body of the original NSX was ahead of its time, current aluminum and ultra-high-strength steel-intensive body architecture has been taken to the limit for supercar design.

"For this new NSX development, anything and everything that could offer incredible base rigidity and lightweight design was on the table," said Shawn Tarr, principal engineer and Acura NSX body development leader. "We considered all-aluminum unibody, carbon fiber monocoque and space frame designs and ultimately engineered a multi-material space frame because it offers the lowest weight and best rigidity, precision and hybrid powertrain packaging capability of any design."

A key advancement in casting technology allowed the NSX development team to realize a quantum leap in body design, for the first time being able to engineer a vehicle with castings in key locations for rigidity, that also support the ductility necessary for placement within crush zones.

World's First Application of Ablation Casting 
The Acura NSX heralds the world's first application of ablation casting technology in the automotive industry. Ablation casting combines traditional casting methods with rapid cooling techniques to offer the design flexibility and rigidity of casting with the ductility and energy absorption characteristics of extruded material.

Traditional castings provide the ultimate rigidity in space frame and other body designs, but have traditionally suffered a major drawback: traditional castings are brittle. With the no-compromise performance goals of the NSX, a groundbreaking new casting method within the crush zones had to be used.

• The ablation process allows the ultra-rigid castings to be located within the crush zones and to function as large aluminum nodes, or junction points. Aluminum extrusions are then inserted into sockets in the ablation cast nodes, which act as fixtures that hold the space frame in place during welding.
• During the welding process, shorter stitch welds can be applied, enhancing the exceptional, repeatable precision of the NSX space frame construction by reducing heat deformation during the production process.
• Ablation castings also enable traditional aluminum castings to be used at strategic locations in the space frame and as the primary mounting points for suspension and power unit components, in addition to being the reference and temporary attachment points during the highly accurate space frame construction process.
• Full space frame construction and vehicle assembly are conducted on-site at the new Performance Manufacturing Center (PMC) in Marysville, OH, providing a high level of quality control.

New A-Pillar Construction Technique
In addition to the world's first casting technology, the NSX applies an all-new three-dimensionally formed ultra-high-strength steel A-pillar that provides next-generation rigidity and precise shape specification tolerances.

The previous generation NSX had a thin A-pillar that provided very good outward visibility. Reflecting this heritage with modern rigidity and roof crush performance requirements demanded this new, ultra-high-strength production method.

Advanced Materials Strategy
NSX represents an advanced expression of modern body design theory: the strategic integration of multiple materials to achieve optimal body performance for numerous targets, including rigidity, dynamic response, superior fit-and-finish and occupant protection.

• The aluminum-intensive space frame is complimented with precisely crafted ultra-high-strength steel and anchored with a carbon fiber floor together producing body performance at its peak.
• For the new NSX, the body design and technologies are about more than just raw performance – a goal of any supercar development.  In keeping with the human-centered supercar concept, the NSX development team went further, to optimize how the car's performance capabilities are experienced by the driver through the body.
• Drivers will experience all of the on-the-rails handling provided by the Sport Hybrid SH-AWD power unit because it is communicated in high-fidelity through the most rigid body in its class.

Total Airflow Management
Engineering a Next Generation Thermal and Aerodynamic Package via Total Airflow Management

To meet the challenge of the ambitious performance targets, radical packaging design and exotic styling for the next generation Acura NSX, the development team had to totally re-imagine the thermal and aerodynamic engineering for this modern supercar so that maximum energy is extracted from the flow of air around and through the NSX with the highest efficiency.

This new total airflow management strategy supports component cooling, aerodynamic performance (drag and downforce) at a very high level without the use of active aero technology, while also contributing to even more dynamic styling.

Computational fluid dynamics (CFD) was used extensively during development to allow the U.S.-based development team to maximize the performance of a power unit being developed in Japan. CFD models were run on computers totaling many years' worth of computational uptime.

Thermal CFD was effectively used in two ways during development: first, for the proof-of-concept in establishing heat management strategy at the earliest development stage and second, for continuous thermal performance improvement as the vehicle matured through development. Extensive involvement of thermal CFD with design engineers during the development enabled maximum design optimization.

Along with the use of advanced CFD, wind tunnel and real world testing, the development team also employed computerized lap-time simulation models of some of the world's most legendary proving grounds that could then be run on chassis-dynamometers allowing testing and validation of computer models for thermal management.

• The all-new NSX employs 10 air-cooled heat exchangers responsible for cooling the front twin-motor unit (TMU), twin-turbo V6 engine, rear direct-drive electric motor and 9-speed dual clutch transmission (DCT).
• The all new, twin-turbocharged 3.5-liter V6 engine at the heart of the Sport Hybrid SH-AWD power unit requires the greatest cooling and receives it through three radiators: one center and two side units to get maximum airflow volume and efficiency. The center radiator is tilted forward 25-degress, allowing the largest, optimized configuration that best utilizes the inherent pressure gradient while maintaining the strict low center of gravity targets of the NSX's Advance Sports Package.
• Condenser and power drive unit (PDU) coolers are efficiently packaged in front of the center engine radiator.
• The TMU is cooled passively through strategic use of air in the front motor room and by a heat exchanger mounted in front of the right engine sub-radiator.
• The 9-speed DCT is cooled by two heat exchangers, one mounted in front of the left engine sub-radiator and the other in the engine compartment.
• Twin-intercoolers located in the signature side intakes are used to cool the intake air charge.

Supercar Aerodynamics
NSX achieves top-class aerodynamic balance and supercar aerodynamic downforce without the use of active aero. Aerodynamic drag is minimized, even while moving large airflows through NSX as it inhales and exhales. Aerodynamic downforce is created through the total airflow management focus on utilizing airflow through each vent, as NSX exhales, and through more traditional aerodynamic shape optimization.

NSX has undergone extensive testing at the company's state-of-the-art wind tunnel in Raymond, Ohio, using ultra-detailed 40-percent-scale models that replicate all of the intake and exhaust vents, heat exchangers and major under-hood components. These highly accurate scale models replicate drag and lift performance with near perfect approximation. It has been verified and put through its paces at the company's full-scale wind tunnel in Japan, and on real and simulated proving grounds throughout the world.

Total airflow management vents and precision ducting also help create strong, consistent downforce for NSX and were tuned to optimized forms with aerodynamicist and designer input during working wind tunnel sessions.

• Six vortices flow at the rear of the NSX including those that support creating the highest downforce across the rear deck lid.
• Flowing from below the car and exiting through meticulously optimized lower, rear diffuser fins is a critical vortex that further anchors NSX to the ground. Uniquely, the fins are not parallel to each other, but are narrower toward the front of the car and wider at the rear. This design creates low pressure and further maximizes downforce.

Sport Hybrid Super Handling All-Wheel Drive
A new handling paradigm decades in the making

The groundbreaking Sport Hybrid SH-AWD dynamic torque vectoring technology applied to this all-new NSX represents research and development that has been ongoing for well over two decades.

Next-generation torque vectoring
Acura has been continuously refining its advanced torque vectoring technology while in parallel developing new ways of accomplishing the timeless sports car values of lightweight, rigid chassis and potent powerplants. This all-new Sport Hybrid SH-AWD represents a system injected with more electric power, delivered more directly, managing more internal combustion power than any system Acura has engineered to date.

In keeping with the development team's 'human-centered supercar' concept, the new NSX and its Sport Hybrid Super Handling drivetrain were truly engineered from the driver out. While the NSX provides a new sports experience with 'on rails handling,' its Super Handling technology was optimized to enhance the driving experience by responding instantaneously and intuitively to the will of the driver.

• Super Handling is brought to its pinnacle form in NSX where the strengths of electric motors –delivering zero delay acceleration – allows the NSX to offer dynamic torque vectoring even at low vehicle and engine speeds.
• Super Handling logic has progressed along a parallel path with hardware. While many advanced automotive technologies are focused on feedback, measurements of how the vehicle is reacting, NSX uniquely applies additional technology to focus on accurately responding to driver input through immediate, precise application of torque at each wheel at any moment.
• Using cutting edge computer-aided engineering (CAE) optimization software, engineers created a double-wishbone, double lower control arm front suspension that decouples the twin-motor unit (TMU) torque from the driver's experience at the steering wheel, providing timeless sports car steering communication to the driver with a new experience of on rails handling provided by the precise torque vectoring of the TMU.
• Variable gear ratio steering is applied to further enhance the confident, race-ready driving dynamics of the all-new NSX.

Powertrain
Sport-Hybrid SH-AWD Power Unit 
Powering the Sport Hybrid Power Unit with Racing Technologies

As announced at the 2015 North American International Auto Show, the new NSX will utilize an all-new power unit from a clean sheet design. At its heart is an all-new longitudinally mounted twin-turbo V6 engine that is mated to an all-new, Acura-developed 9-speed DCT with an electric motor that applies its torque directly to the crankshaft for higher output with immediate power delivery to the rear wheels.

• The new engine has a displacement of 3.5-liters and utilizes pinnacle racing technology, applying both direct and port injection to its design.
• The 75-degree V-angle and dry sump design optimizes engine rigidity and further supports the NSX's Advanced Sports Package by allowing the engine and components to be lowered in the chassis to the maximum extent, resulting in the lowest center of gravity in its class. This also supports the advanced packaging of other engine components. 
• The engine's dry sump design also helps maximize vehicle performance in high lateral-G conditions.
• The rear direct-drive electric motor applies its torque directly to the crankshaft.
• The 9-speed DCT's main, counter, secondary and output shaft design maximizes the advanced sports package through a configuration that lowers weight and helps to center the mass nearer the driver.

With dramatic new styling, precise handling and a host of advanced technology and safety features, the fourth-generation TL is Acura's performance leader TORRANCE, Calif. - Since inception, the Acura TL performance luxury sedan has set lofty standards for styling, performance, comfort and technology. Available for 2009 in two distinctly different models, TL and TL SH-AWD®, the all-new fourth-generation Acura TL dramatically expands the model's capabilities and appeal with evocative style, a choice of two VTEC® powertrains (including a new 305-horsepower V-6) and the TL's first-ever application of Super Handling All-Wheel Drive™ (SH-AWD®).



Boasting larger dimensions, optimized suspension, a new Sequential SportShift transmission, plus an available Technology Package featuring a comprehensive array of navigation and communication aids, the 2009 TL offers more appeal than ever before. Along with an available Acura/ELS Surround® premium 10-speaker surround sound system and an all-new AcuraLink® weather feature, the new TL is by far the most technologically advanced sedan in Acura's history.

The combination of dramatic new styling, exhilarating performance and an extensive array of electronics (including AcuraLink® real-time traffic and AcuraLink® weather with Doppler-style radar mapping) ensures the 2009 Acura TL will appeal to a sophisticated, technology-savvy audience.





Powertrain
A choice of two different all-aluminum VTEC® engines enables the new 2009 TL to satisfy a wide range of customers. Standard is a 3.5-liter V-6 producing 280 horsepower and 254 lb-ft of torque that sends power to the front wheels through Acura's sophisticated Sequential SportShift 5-speed automatic transmission with steering-wheel- mounted paddle shifters and Grade Logic Control. Though powerful, the new engine is also fuel efficient, with projected EPA fuel economy ratings* of 18 mpg city and 26 mpg highway. The engine is targeted to meet California's tough CARB LEV II ULEV emissions certification standards, thanks to features including a Drive-by-Wire™ throttle system, Computer-Controlled Programmed Fuel Injection (PGM-FI) and Variable Valve Timing and Lift Electronic Control (VTEC®) for the intake valves.

Serious performance-sedan devotees will choose the TL SH-AWD® to make winding roads their own. Its all-new 3.7-liter V-6 engine produces 305 horsepower and 275 lb-ft of torque courtesy of greater displacement and additional high-performance features like Variable Valve Timing and Lift Electronic Control (VTEC®) on both the intake and exhaust valves, and a special high-flow dual exhaust system. With projected EPA fuel economy ratings* of 17 mpg city and 24 mpg highway, the 3.7L is also targeted to meet California's stringent CARB LEV II ULEV emissions certification. The pièce de résistance on the TL SH-AWD® is the Super Handling All-Wheel Drive™ system, now available on the TL for the first time.

During spirited cornering, SH-AWD® seamlessly distributes more torque to the outside rear wheel to create a "yaw moment" to help the TL turn in more quickly and precisely - while also continuously apportioning drivetrain torque front to rear and left to right. The result is a remarkably balanced and precise all-wheel-drive performance sedan that excels year-round, not just during inclement weather.

Acura TL's performance achievements extend to durability, reliability and refinement as well. Both engines feature electronically controlled engine mounts to reduce engine noise, vibration and harshness (NVH); quiet and efficient Electric Power Steering (EPS) and maintenance-free serpentine accessory belt also boost operating refinement. A standard Maintenance Minder™ system and up to a 100,000-mile tune-up interval offer further time and cost savings for the TL owner.

The standard transmission on the 2009 TL and TL SH-AWD® is a Sequential SportShift 5-speed automatic featuring F1®-style steering-wheel mounted paddle shifters and Grade Logic Control. Merging the convenience of an automatic with the enjoyment of SportShift manual gear selection, the transmission also features an overdriven top gear for maximum fuel efficiency on the highway. In fact, the Acura transmission has the widest gear-ratio spread of any 5-speed transmission in its class, providing strong acceleration in lower gears and relaxed, fuel-efficient highway cruising.





Body/Chassis
Major improvements in structural engineering for the unit-body further define the 2009 TL. The list of substantial changes begins with the relocation of frame rails inside (rather than underneath) the vehicle's floor pan, resulting in a nearly flat body underside. Benefits of this design include improved crash safety, a significant reduction in interior noise levels, and reduced aerodynamic drag that helps enhance fuel economy. Another significant improvement is the increased use of high-strength steel, which simultaneously improves the unit-body's overall strength while helping to reduce weight. For additional weight savings, aluminum is used for the hood, the front suspension subframe and rear suspension knuckles.

Ride quality and passenger comfort benefit from the 2009 TL's larger exterior dimensions. Featuring 6.0 inches greater exterior length, 1.8 inches more overall width and Ride quality and passenger comfort benefit from the 2009 TL's larger exterior dimensions. Featuring 6.0 inches greater exterior length, 1.8 inches more overall width and a modest 0.5-inch increase in overall height, the TL is noticeably larger than its predecessor.

The larger body size directly contributes to greater interior roominess; it also allows a 1.4-inch longer wheelbase to improve ride quality and a significantly wider track (1.1 inches wider in front, 1.8 inches wider in the rear) helps generate even more tenacious cornering power. The TL employs a double-wishbone independent front suspension and a multi-link independent system in back.

Further improving ride quality and road-holding are new dual-stage "blow off" style hydraulic suspension dampers, new hydro-compliant bushings (used to mount the transmission and key suspension components) and a new "smart" engine mount design. On the Super Handling All-Wheel Drive™ (SH-AWD®) model, more performance-minded suspension and brake tuning, larger wheels/tires, racing-inspired front brake cooling ducts, and specially-tuned Electric Power Steering (EPS) take the enthusiast's driving experience to an even higher level.





Exterior/Interior
An evocative and powerful exterior body design dramatically advances the TL's image as a performance luxury sedan. Designed by Acura in Southern California, the TL utilizes an array of styling techniques to express motion - and emotion - even when the car is at rest. Featuring Acura's new signature front grille, body sides defined by strong character lines, sweeping C-pillars and new LED taillights, the 2009 TL is simultaneously Acura and yet wholly unique. Plentiful use of luxury and performance features add visual appeal while adding to the TL's vigorous statement - including bright HID projector-beam front headlights, pronounced wheel arches, a standard power moonroof and genuine stainless-steel body trim.

Wheels and tires are as expressive as the exterior styling. Standard on the 2009 TL are 17-inch aluminum wheels with P245/50R17 all-season Bridgestone Turanza or available Michelin Pilot tires for confident year-round performance. The TL SH-AWD® comes with 18-inch aluminum wheels with lower-profile P245/45R18 Michelin Pilot tires for more agile handling. Finally, the TL SH-AWD® offers available 19-inch aluminum wheels with aggressive P245/40ZR19 Michelin Pilot Sport PS2 summer tires for the ultimate TL performance experience.

In keeping with its mission as a driver's car, the 2009 TL interior features a new "dual personal" layout that provides both the driver and front passenger with their own personal space. Thanks to its larger exterior dimensions, the new TL has 1.3 inches more rear legroom and 0.5-inch of added rear shoulder room compared to the previous generation TL.

Acura's commitment to luxury and technology becomes apparent from the first moment the driver's door is opened. With sweeping shapes, generous use of premium materials and passionate attention to detail, the TL rewards the discriminating eye. The design and execution of the interior is an artful combination of leather surfaces, accented by metallic and wood-pattern trim. An impressive array of premium standard features includes a power moonroof, dual-zone adaptive climate control, 10-way adjustable (8-way power seat with 2-way power lumbar support) driver seat, 8-way adjustable power front passenger seat, and steering-wheel-mounted F1®-style paddle shifters for the Sequential SportShift automatic transmission. An 8-speaker, 276-watt audio system that includes a 6-disc CD changer, AM/FM radio, XM® Satellite Radio, Bluetooth® Audio, USB port and AUX jack connectivity, and HandsFreeLink® wireless telephone interface are standard.

An intuitive interface dial as well as sophisticated voice recognition capability simplifies control of this impressive technology. Premium Milano leather seating surfaces included in the Technology Package further enhances comfort and visual appeal.





Safety
Advanced Compatibility Engineering™ (ACE™) represents a major advance in structural engineering for the 2009 TL. In simple terms, ACE™ better dissipates crash energy in a severe frontal collision through the use of dedicated load-bearing frame structures that efficiently distribute crash energy through the body structure—while also helping to preserve the integrity of the passenger compartment. Acura first introduced ACE™ to the Acura line for the 2005 model year and its inclusion in the 2009 TL means that every vehicle in the Acura model range now has this advanced safety engineering.

Six airbags and a new Active Head Restraint System for the driver and front passenger headrests top the long list of passive safety features built into the new TL. The airbag array includes dual-stage, dual-threshold front airbags, new dual-chamber front seat side airbags with front passenger seat Occupant Position Detection System, along with side-curtain airbags for all outboard seating positions. Additional passive-safety features include 3-point seatbelts and head restraints for all seating positions, driver and front passenger seatbelt load-limiters with an automatic tensioning system and a Lower Anchors and Tethers for CHildren (LATCH) system that permits quick, secure attachment of up to two child seats in the rear seating area.

The new TL includes sophisticated active safety features including powerful 4-wheel disc brakes (with ABS, EBD and Brake Assist), Vehicle Stability Assist (VSA), Tire Pressure Monitoring System (TPMS), all-season tires and an available SH-AWD® system. Adding to the list of standard exterior safety features are daytime running lights (DRL) along with 2.5-mph front and rear bumpers.

The 2009 Acura TL is designed to meet the latest crash-safety regulations, including the new FMVSS214 side crash standards (which the TL meets three years early) and the new FMVSS301 rear crash standards. Internal testing indicates that the 2009 TL should achieve the highest ratings in National Highway Traffic Safety Administration (NHTSA)*** and Insurance Institute for Highway Safety (IIHS) crash tests.





The 2009 Acura TL is assembled in Marysville, Ohio and is covered by a comprehensive 4-year/50,000 mile bumper-to-bumper limited warranty and a 6-year/70,000 mile powertrain limited warranty. Additional benefits of ownership include Acura Total Luxury Care (TLC), which provides free 24-hour roadside assistance, concierge service and trip routing.

2) Honda Press Conference at the 2008 NAIAS

http://world.honda.com/NAIAS2008/HondaConference/video/



"I was a young engineer participating in an important emissions certification test for the Civic at the EPA lab in Ann Arbor. We believed that clean air was important for the future of life on this earth. And we made it a central focus of our product development efforts.

It was November 1974 and Civic became the first vehicle to pass the new standards of the U.S. Clean Air Act based solely on engine performance. But what I remember most ...was, that the EPA inspector congratulated me for achieving the industry's top rating for fuel economy." - Takeo Fukui, President and CEO Honda Motor Co., Ltd.

2009 Acura TSX, RL, and TL Rumors

TSX:
- Onsale date has been "confirmed" to be as soon as April 24, 2008.
- Initially, only front wheel drive (possible SH-AWD in future?).


The 2009 Acura TSX will offer 8 exterior colors and 3 leather trims.

RL:
- The 2009 Acura RL will be the world's first production model with the XM weather function (fact).
- Will be getting cooled front seats (which were always offered in Canada).
- Engine still will be 3.5L, but now will output 306hp.- New edgier look.

TL:
- Supposedly, getting a 3.5L for the front wheel drive version and a 3.7L engine for the SH-AWD version.

Acura Changes Direction for RL

A lot of car sites have been talking about how the Acura TSX will be the first in the brand to see the new 4 cylinder diesel engine, and how there will be a V6 version most likely for the TL and MDX. Well... isn't news like this just obvious after Honda stated that i-DTEC was coming to Acura? The European has had a diesel Honda Accord, which is the Acura TSX to us Americans, for awhile now. And we pretty much know the TSX will not be getting a V6 option, so I won't waste anymore time on this right now.

The news I found interesting was Acura's goal of becoming a tier 1 automaker in 4-6 years, truly competing with the likes of BMW and Mercedes. One of Acura's weaknesses right now is the current generation RL. The RL is Acura's "flagship" sedan, however it has trouble matching up against other luxury brands, most likely due to the lack of V8 and rear-wheel drive options.

Dick Colliver, executive vice president of American Honda Motor, acknowledged that the Acura RL was the "wrong car" for the segment. A new RL is slated for 2010, and that the car's overall direction will change. Hopefully, this will address the weak sales of Acura's range-topping RL sedan.

Hmmm... I wonder what they're going to do to the RL. Whatever it is, the next RL should look less like a bloated Honda Accord and have more aggressive styling.

Diesel for Acura in 2009

Honda's premium Acura brand will be the first to get the new 4 cylinder i-DTEC engine in 2009. Models fueled by V6 diesel engines will follow after 2010. Honda's CEO, Takeo Fukui, said Honda's clean diesel cars will not require a urea tank as most European systems do. Honda's new diesel drive train generates and stores ammonia within a two-layer catalytic converter to turn nitrogen oxide into harmless nitrogen.

The use of aluminum in the cylinder block instead of steel would also allow it to manufacture the engines using its existing gasoline engine facilities, keeping initial investments down. Mr. Fukui expects Honda's sale of four-cylinder diesel cars to reach about 150,000 vehicles globally by around 2010 with the planned roll-out in the United States and Japan.


i-DTEC: A combination of optimized combustion chamber design and reduced injection time results in a clean, quiet engine that delivers excellent performance for an enjoyable driving experience. In addition, the i-DTEC engine meets the ultra-stringent U.S. EPA Tier II Bin 5 emission standards without the on-board storage of urea.

No Rear-Wheel Drive for Acura?

Honda's CEO, Takeo Fukui, states next Acura NSX will have a V10 engine with rear-biased SH-AWD. He also commented on how they're trying to keep the weight of the car down to "be faithful to the original NSX's 'everyday supercar' formula." Mr. Fukui did not give any details on the time line of the next NSX. When asked if Acura was working on any FR (front engine with rear-wheel drive), Honda's CEO "referred to the FR SH-AWD NSX successor and suggested that Honda could take what they learned from that development program and apply it to other vehicles."

A little disappointing because this kills the rumors that the next NSX is a mid-engine V8 with "true" rear-wheel drive supercar. It also seems like Acura is not getting a "true" rear-wheel drive platform for a long time (if ever), and the closest we're going to get is a rear-biased SH-AWD.

Honda will further accelerate a focus on the following three pillars:

1. Strengthening the foundation for global growth

Europe - Automobile:
In the first half of 2008, the all-new Accord Sedan and Tourer will be introduced to the market. The mass production models will be introduced at the Geneva Motor Show in March 2008. The all-new Accord will be equipped with an i-DTEC engine, which complies with the Euro 5 emission standard expected to become effective in 2009. - (This all-new Accord will most likely be introduced in the States as the next geneation Acura TSX.)

2. Strengthening the foundation for global growth:

Hybrid:

(It must be noted that Honda has no intentions of making an Acura hybrid, but it's still nice to know what Honda is getting.)

* In addition to Civic Hybrid, Honda will introduce a new dedicated hybrid vehicle in 2009. The new dedicated hybrid vehicle will be equipped with a newly developed lightweight and compact IMA (integrated motor assist) system and offered at a more affordable price level base on Honda's efforts to significantly reduce cost. The worldwide sales plan for this vehicle is approximately 200,000 units annually.

* A new sports hybrid, based on the CR-Z introduced at Tokyo Motor Show, will be sold globally.

Diesel:
* The second-generation i-DTEC engine will first be installed to models for European markets in 2008, North America in 2009, and Japan will follow. (An Acura diesel may not be totally out of the question.)

3. Accelerating our efforts in Japan to strengthen the core characteristic that make Honda unique:

R&D Capabilities:
* In addition to test courses, Honda decided to build a product development facility dedicated to the Acura brand within the new R&D center being constructed in Sakura with an aim to strengthen product development for the Acura brand.

* In April 2006, Honda R&D launched a new organizational structure separating the product development functions for the Honda and Acura brands. With the addition of a dedicated development facility for the Acura brand, Honda R&D will further strengthen product development capabilities which clearly define the unique characteristics of each brand and accelerate product development that offers new value for the customer.

Production:
Automobile - Construction of a new engine plant in Ogawa and new auto plant in Yorii began in fall 2007 with a target to begin operations in 2009 and 2010, respectively.

Automobile Business in Japan:
* To further strengthen the Honda brand, all-new versions of four different vehicles will be introduced in Japan during 2008. Honda's goal is to expand sales by offering attractive products which bring more joys to customers.
