Technical Details of the Next Gen Acura NSX

In advance of the market launch of the highly anticipated next generation Acura NSX, the engineers leading the supercar's development shared new technical details and design strategies with the automotive engineering community at the April 22nd SAE Detroit Section dinner, held in conjunction with the SAE 2015 World Congress and Exhibition. Additional information about the team's efforts to achieve a true "New Sports Experience" included details of the NSX's world's first body construction process that helped create a multi-material space frame resulting in class-leading body rigidity, the advanced total airflow management system and an update on NSX's power unit specifications.
Ted Klaus, chief engineer and global development leader of the new NSX, introduced key powertrain, body and dynamic performance engineers who shared new product and technical details in their related areas of the development. The unprecedented sharing of technical details prior to the car's market introduction reflects the desire of the NSX development team and the company to inspire the imagination of automotive and technology enthusiasts along with the next generation of engineers.
"Our goal is to create something altogether new and exciting, something that advances the concept of a next generation supercar in the spirit of the original NSX," said Klaus. "In order to provide NSX-level value, we needed to push ourselves to experiment with, refine and then realize many new technologies."
Significant technical revelations concerning the NSX included:
  • The NSX includes Acura's first use of a revolutionary multi-material space frame design that delivers class-leading body rigidity while remaining lightweight.
  • World's first automotive application of new ablation casting1 technology resulting in world-class body rigidity for ultimate handling and control.
  • World's first use of a three-dimensionally formed, ultra-high-strength steel A-pillar, supporting class-leading rigidity and crash performance while providing outstanding outward visibility.
  • The NSX achieves top-in-class aerodynamics targets without the use of active aerodynamic elements, while its three-motor Sport Hybrid power unit is cooled through 10 heat exchangers all thanks to a total airflow management strategy that maximizes the flow of air around and through NSX.
  • Displacement of the NSX's all-new twin turbo V-6 engine was confirmed to be 3.5-liters.
  • The NSX will mark the introduction of the most capable and highest torque capacity Super Handling All-Wheel Drive system in Acura history.
  • The latest proprietary logic advances Acura's two decades-long pursuit of Super Handling that proactively responds to driver inputs, allowing the NSX to achieve a new level of line trace while at the same time intelligently supporting the driver in changing environments.


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.


About NSX
The all-new Acura NSX represents the convergence of timeless sports car values and advanced technology in a pinnacle supercar. Timeless sports car values include classic goals like a rigid and light chassis with the mass placed low and close to the driver. Advanced technologies include those that enhance the driving experience in new ways.
To bring back the legendary NSX the global development team has innovated in the critical, timeless areas of frame and aerodynamics in addition to tirelessly refining its key advanced technology - the state-of-the-art hybrid power unit. The NSX has many innovative components, but the basic recipe is simple: timeless sports car values blended perfectly with advanced technologies that deliver a new sports experience.

Next Gen Acura NSX Delayed?

Rumor has it that the next generation Acura NSX will be delayed for at least 6 months. A couple of things could have helped cause this schedule change.

First, there was a crash at Honda's Takasu Proving Ground in May (2014). Reports are saying that a car went off course while testing and two men in their 20's were hurt. The passenger was transported to a nearby hospital while the driver sustained minor injuries. Rumors are saying the vehicle was the new NSX.



If that wasn't bad enough, now there are images of a charred NSX destroyed due to fire while testing on the Nurburgring in Germany. The camo-ed prototype was completely destroyed after the engine compartment caught fire at the end of July (2014).



Here's video of the test NSX without fire:

My 2005 Acura TSX Alternator Died

So it happened, my alternator died leaving me dead on the road in the rain last Thursday, February 6, 2014. My day started out normal, wake up, get ready for work, and jumped in the car to drive to work. Not even a quarter mile into, I see the battery icon light up. I thought to myself, "I don't think this means the battery is low because I have had to change a low battery before and this never popped up before." Maybe it's just a false warning. I work only about 5 miles away so I get to work without any issues. Told myself that I will look up this indicator light when I'm at my desk, but never actually do because of the busy day and totally forget about it.

Fast forward about 8 hours, I jump back into my car and start it. Again the battery light is on! So it's probably not a false warning but I don't really know exactly what this light is warning me about, something battery/electrical related. I start heading home, but it's rush hour in the rain, and for some reason most San Diegans are terrible drivers in the rain. All of a sudden, my radio goes silence. I thought to myself, is it just this station or is it my radio? Checked the next station... no sound... Quickly turned off the radio and started to make my way to the left lane in case I am going to breakdown. As I was thinking that, my fuel and temperature gauges drop all the way down to zero. About a minute later, my dash fully lights up! I don't know what's exactly going on, but I told myself, "You need to pull over into this parking lot!"

I parked somewhere out in the open in case I needed to jump my car. I texted my fiancee and brother, both who didn't respond right away. My plan was to wait for traffic to die and try to make it 4 miles home. As I was waiting around, I was googling on my phone the battery indicator. Basically, the internet didn't tell me anything new: electrical problem most-likely alternator. My fiancee finally got back to me about 30 minutes later asking what I wanted her to do. I told her I wanted to drive it home after traffic died down, but as I was saying that, it occurred to me that even if I get it home, it might be stuck there and I will probably need to tow it to my mechanic anyways. So now I wanted to wait until traffic died and drive it to my mechanic, which was about 7 miles away, 6 of which are on the freeway.

My fiancee picks me up and we eat dinner while waiting for the traffic to die down. I get jumper cables out of my car after getting back to it. They're basically part of my bug out bag in my car. I used my fiancee's car to charge my battery. After what seemed like a long time, but was really only 20 mins, we headed out. The plan was to have her drive behind me to block car if anything happened.

After waiting at the first light for 3 mins, which seemed like forever, all the symptoms of electrical problems appeared again! However, this time there was another symptom, my car couldn't really move when I stepped on the gas! My engine revved but I wasn't going anywhere. I played with changing the gears for a little bit and somehow my car started rolling again. I accelerated to the next light and I could see that my headlights are out. So my dash is basically all dead, car isn't going when I tell it to, my headlights are out, all in the rain. There's no way I'm getting on the freeway like this, I need to pull over and get this towed! So I turned off onto a side street to try to turn into the first parking lot I see... but I couldn't make it. My car died at the intersection to the parking lot. :( The lucky thing was I was no longer on the main road, and I wasn't caught in the middle of the intersection. My fiancee pulls up next to me and I start charging my battery again, just trying to make into the parking lot. As the battery was charging, I called a tow truck, $45 hook plus $5 per mile.

The tow truck arrived moderately fast, took about 30 minutes. I towed my car to my mechanic, the tow guy knew where it was. After paying the tow truck, I took my car key off my ring and threw it in my mechanic's mailbox. I thought to myself, I couldn't drive it for 4 miles, good luck to anyone who wants to steal it and drive 4 miles.

The next day, I worked from home and called my mechanic to tell him what's up. He said he would check the battery and alternator and would call me back. As promised, I received his phone call and told me my alternator is bad and I would need a new battery too. $275 for the alternator and $100 for the battery so $375 installed. I asked what happened and his response over the phone was "the battery is too strong and it killed the alternator". I didn't really get it but the conversation ended there.

I picked up my car the next day and wanted to clarify what he meant about the battery being too strong because I changed my battery at Walmart 2 years ago and this is they battery they said went with my car. He told me when he tested my alternator, it was smoking. When he tested my battery it was about 14 volts. The battery is supposed to be around 12 volts. He said the alternator was overworked because it always needed to charge the "strong" battery.

I bought my 2005 Acura TSX in the December of 2005.
