A huge leap in NSX production news! The 2017 supercar’s tech specs are official today, and they are enough to flood your brain’s pleasure centers. 573-horsepower, 9-speed DCT with eAWD, and a top speed of a screaming 191-mph.
Power for the gasoline V6TT comes in at 500-horsepower, with a stellar 406-pound-feet of torque from just 2000-rpm. Along with the wide spread of gear ratios in the dual-clutch automatic, the NSX will be an absolute rocketship. Based on the initial buzz about drives at Togichi and Sonoma raceway, the hashtag is #scaryFast.
Is this a good thing overall? Abvsolutely! But with the complex new package of three hybrid Direct Drive motors, there is still much to learn about the machine.
We are closer than ever before, however, thanks to this fresh data and photo-set from Acura. Check out the full launch packet and exhaustive specs/features/options at the footer of this page.
There is a posh new website for the NSX up now, and even the NSX Collection of fashion accessories…. Yet we are missing a few critical details about the NSX’s springtime arrival to first owners:
We’re smiling right now, and hoping that the NSX is a $100k exotic delivering 3.0-second sprints to 60-mph. That would be a stellar position in the market, right beside the Corvette Z06 and Nissan GT-R.
Alternatively, the exotic tech of the NSX may command a stiffer entry price than that prediction. In an LF-A scenario, which we do not expect at all, the NSX would be priced closer to the 2016 911 Turbo and McLaren 570S in the $175k ballpark.
Or perhaps somewhere in between.
Thrilling times ahead for the new Acura halo hypercar.
2017 Acura NSX
2017 ACURA NSX: Introduction
When the original Acura NSX made its debut 25 years ago, it forever changed the supercar universe by combining scintillating sports car styling and athletic performance—common traits long associated with the exotic car segment—with a new dimension of quality, exceptional ergonomics, comfort, and dynamic poise. The NSX introduced and defined Acura’s approach to “Precision Crafted Performance” with its cutting-edge design and innovative technology that provided accessible supercar performance for real drivers in the real world.
By making use of advanced new technologies such as a lightweight yet rigid all-aluminum monocoque body/chassis and a mid-mounted transverse V6, the original NSX challenged the conventional wisdom for a supercar. Its high-revving V6 engine featured a number of innovative production car technologies including forged pistons, titanium connecting rods and VTEC valve train.
Moreover, the NSX sought a more intimate connection between the car, the driver and the road underneath them, pursued through essential design elements – light weight, open and airy cockpit, and excellent ergonomics – creating an altogether new and paradigm-challenging definition of supercar performance.
Next Generation Concept
The overarching concept for the design and development of this next-generation NSX was the idea of a “human-centered supercar,” one that places the driver at the center of its mission in each and every element of its design and dynamic performance.
Respecting the foundational concepts of the original NSX—accessible supercar performance, everyday drivability, and openness to new technology—this next-generation NSX pursues an altogether new and revolutionary concept of Acura supercar performance – melding timeless NSX values with advanced technologies to create a New Sports eXperience.
Advanced Fundamentals (Timeless NSX Values)
First and foremost, the engineering team felt a tremendous responsibility to continue the fundamental innovation pursued by the original NSX team. Four foundational philosophies are fundamental to the timeless NSX values and essential to realize the new NSX concept and goals:
- Total Airflow Management – a wholistic approach to thermal management and aerodynamic performance that supports and enhances dynamic response and high-speed stability without the need for active aero devices
- Human Support Cockpit – a cabin that supports the driver and amplifies the driving experience with no sacrifice to comfort or everyday usability
- Multi-Material Body – light and ultra-rigid body, applying material, construction and joining methodology optimized to the mission of each body component
- Advanced Sports Package – optimizing the design and packaging in all the above aspects—the human package, the body, and finally the key components of the power unit to lower and center the mass of the vehicle.
With these fundamentals in place, NSX engineers could effectively develop technical solutions needed to deliver the New Sports driving experience they sought.
To fully realize this New Sports eXperience, Acura electrifies the advanced fundamentals by leveraging its longstanding Direct Yaw Control knowhow through its Sport Hybrid Super Handling All-Wheel-Drive (SH-AWD) system, the first of its kind in the supercar realm.
The NSX concept for “zero delay” is more than acceleration, actually involving every aspect of the driver interface … the capacity to directly respond to the driver’s demands in all three phases of driving: Go, Stop, Turn (acceleration, braking and cornering). The NSX’s advanced power unit supports this achievement. Zero delay acceleration and active AWD traction power the NSX out of corners. Energy recovery supports direct and linear braking. And power strategically applied to the wheels directly creates a yaw moment to help turn the car according to the driver’s will.
Marrying new approaches to vehicle design fundamentals, including advanced body construction, component packaging and aerodynamic optimization, with an advanced and electrified new expression of Acura’s direct yaw control concept results in a supercar that faithfully translates the inputs of the driver with incredible fidelity and zero delay while minimizing the driver’s workload—qualities that define the New Sports eXperience.
Design, Development and Manufacturing
Development of the next-generation NSX involved a global team of engineers and designers, with development of the Sport Hybrid power unit centered in Tochigi, Japan. Development of the body, chassis, electrical, interior and other vehicle technologies including total system integration, was concentrated in Raymond, Ohio. Initial styling design for the NSX was conducted at the company’s Wako design studio in Japan, and was evolved for production by the Acura Design Studio in Los Angeles.
Throughout its roughly four-year development, the fundamental “human-centered supercar” concept for the next-generation NSX remained clear and consistent. However, the technologies and means by which the R&D team would realize their concept underwent a process of continual improvement and evolution, most notably in the area of engine design. Whereas the original direction called for a transverse-mounted, normally aspirated V6, the NSX development concept evolved to a new and more challenging approach: an all-new bespoke twin-turbocharged, longitudinally mounted V6. This radical re-imagination of the engine design had profound implications for every element of the NSX design—the package, cooling, aerodynamics, chassis and more.
The NSX has been tested and tuned on streets and race circuits around the world. Primary development was conducted at the Transportation Research Center adjacent to Honda R&D Americas Ohio Center as well as the Honda Takasu proving ground in northern Japan before moving to tracks such as Virginia International Raceway and the famed Nürburgring, followed by global “genteki” events (“at-the-spot” verification) which took NSX on public roads throughout the U.S. and Europe and beyond.
Construction of the NSX will take place at the new Performance Manufacturing Center (PMC) in Marysville, Ohio. The PMC was designed to innovate both the means and the methods of producing low-volume specialty cars and to realize challenging new ideas for next-generation craftsmanship and quality established by the NSX manufacturing team.
The PMC employs approximately 100 associates, including 70 highly skilled manufacturing technicians engaged in body construction, painting, assembly and quality confirmation of the NSX. Among its many innovative processes is the use of robotic MIG welding for the construction of the NSX’s aluminum space frame.
The NSX’s bespoke twin-turbocharged V6 engine is assembled by master engine builders at the company’s engine plant in Anna, Ohio. The engine is broken in on a dyno so that it’s track-ready when it leaves the factory. Then it’s mated to a direct drive motor (part of the hybrid system) and precision balanced as an assembly. Its bespoke 9-speed dual clutch transmission is then attached to the engine and this portion of the total power unit is sent to the PMC. The Twin Motor Unit (TMU) and other hybrid system components are built in Japan and shipped to Ohio for final assembly, completing the overall power unit.
2017 ACURA NSX: Dynamic Performance
The NSX was created to revolutionize supercar performance, delivering a more vivid, immediate and intuitive dynamic experience with zero-delay acceleration, braking and handling – such that the vehicle responds according to the “will” of every driver’s inputs, but truly comes “alive” in the hands of skillful drivers. Fundamental dynamic concepts are as follows:
- Ultimate Rigidity – via the multi-material body, providing the foundation for the zero-delay translation of driver inputs through steering, throttle and brakes. The same strong foundation directly reacts the yaw moment created from our advanced technologies
- Human Fit – exemplified by a cockpit that is optimized in every element of its design to support the driver and clarify the driving experience while providing outstanding comfort and class-leading ergonomics
- Advanced Sports Package – optimizes the design and packaging of all major vehicle systems to lower and center the mass of the vehicle for incredible handling and dynamic response
- Total Airflow Management – a new airflow management approach gives the NSX the superlative airflow management expected of a next-generation supercar, cooling is ducted through heat exchangers and then precisely directed to various exit locations to optimize drag and downforce.
- Advanced Zero Delay Technologies – the capacity to directly respond to the driver’s demands in all three phases of driving: Go, Stop, Turn
- On Rails Cornering – translating driver inputs into vehicle responses with incredible fidelity and amplifying the capabilities of the driver and the car via direct yaw control with next-generation Sport Hybrid Super-Handling All Wheel drive
- Fade-free braking – powerful, linear, predictable and virtually fade-free braking performance in all driving conditions via the seamless integration of high-performance mechanical (Brembo hydraulic) braking and hybrid motor assisted electro-servo (regenerative) braking
- Acceleration – instant acceleration G feeling from the moment the driver engages the throttle, enhanced by the immediate torque response of three electric motors working in concert with the bespoke, twin-turbocharged V6 and 9-speed dual clutch transmission (9DCT)
FUNDAMENTAL ZERO DELAY TECHNOLOGIES:
Ultimate Rigidity (Multi-Material Body)
Like the original Acura NSX—the world’s first all-aluminum supercar—the all-new NSX has a cutting-edge structure: its Multi-Material body, utilizes new materials and construction methods to create a platform with unprecedented dynamic rigidity.
- Space frame torsional rigidity that surpasses anything in its class
- Each suspension point is attached to precision machined castings—including the world’s first automotive application of ablation casting technology—to provide the ultimate, local attachment point rigidity
- Unparalleled platform rigidity transmits the full feeling of the Power Unit, suspension, and steering directly to the driver with zero delay, while maximizing the effectiveness of Direct Yaw Control to improve vehicle dynamics
Human Support Cockpit
From its minimalistic yet contemporary design to its careful application of materials in the seat and steering wheel the team sought to support the driver and clarify the driving experience. The interior of the all-new Acura NSX has a “human-centric” ergonomically-enhanced design theme for both the driver and passenger.
Since steering feel and performance are such an important aspect of the on-rails handling nature of the high-performance NSX, unusually detailed attention was paid to perfecting the steering wheel. This included maximizing grip via a more ergonomic shape and increasing surface contact for the hands, as well as easier operation of the paddle shifters.
To maximize forward visibility, specially designed A-pillars made of ultra-high-strength steel were incorporated into the design of the all-new Acura NSX. These new pillars are actually a full inch thinner than those of the original NSX, but offer enhanced safety performance.
Advanced Sports Package
The new Acura NSX Advanced Sports Package is a design philosophy that seeks to optimize the design and packaging of all major vehicle systems—the body, chassis and interior, including the mid-mounted Sport Hybrid Power Unit (engine, Direct Drive Motor and 9DCT) and key hybrid components including the Intelligent Power Unit (containing the lithium-ion battery pack), PDU and the TMU—to lower and center the mass of the vehicle for optimal handling and dynamic response.
While maintaining ground clearance similar to the highest volume sports car and expanding the head room to accommodate a 95th percentile American male, the new NSX has the lowest center of gravity among its core competitors.
Total Airflow Management
“In many ways, with the design of the all-new Acura NSX, you literally have form following function, so this was a really exciting vehicle to work on as an aerodynamicist,” says Thomas Ramsay, the Aerodynamics and Cooling Project Leader on the new Acura supercar.
NSX’s body shape was effectively designed to minimize aerodynamic drag while creating balanced front-to-rear downforce through a total airflow management focus on utilizing airflow through each vent, while extracting maximum energy from the airflow field to cool the brakes and manage power unit thermal loads.
Through extensive research and development, the NSX aerodynamics team determined that placing approximately three times as much downforce at the rear of the vehicle relative to the front of the car would provide the optimal downforce balance for high-performance driving as well as everyday functionality. Further evidence of the superior aerodynamics engineered into the NSX is that its high level of downforce is accomplished without the need for active aerodynamic bodywork or other devices.
Advanced Zero Delay Technologies:
With the Sport Hybrid SH-AWD, zero delay performance is ensured in virtually any driving scenario:
- When accelerating, the system provides instantaneous torque via its three electric motors—the rear direct drive motor and front Twin Motor Unit—that is maximized at all four tires when accelerating or powering out of corners.
- When trail-braking into a corner, the system utilizes the front TMU for enhanced deceleration—the advanced braking system works in concert with the vehicle’s mechanical brakes to precisely decelerate, and the Direct Yaw Control delivers precise and immediate turn-in performance while allowing drivers to point their eyes toward the corner apexes.
- When exiting a corner, the driver can pick up the throttle earlier and with more confidence and accelerate with added precision and as well as reduced workload.
“Using Honda’s original beta method to consider overall handling performance, we’ve been exploring direct yaw control torque vectoring for over two decades,” says Ted Klaus, Acura NSX Global Development Leader. “With the development of the Sport Hybrid Super-Handling All Wheel Drive System, we can take advantage of the superior responsiveness of the electric motor characteristics within the system powered by an independent Battery to significantly expand the benefits of direct yaw control.”
By taking advantage of the immediate torque response of the system’s three electric motors to heighten the control and effectiveness of direct yaw control, the Acura NSX Sport Hybrid SH AWD system elevates any driver’s confidence and performance driving capabilities while extracting more performance from the car.
2017 ACURA NSX: Sport Hybrid Power Unit
The exceptional dynamic capabilities and zero-delay responses of the new NSX are enabled by the exploitation of advanced powertrain technologies. This concept of utilizing next-generation technology to deliver a New Sports eXperience is epitomized by the adoption of a Sport Hybrid power unit.
At the heart of this new hybrid power unit is a bespoke, mid-mounted twin-turbocharged, 75-degree 3.5-liter DOHC V6 engine with dry sump lubrication, mated to an all-new 9-speed dual clutch transmission (9DCT) and Direct-Drive Motor. This is augmented by the front Twin Motor Unit (TMU) driving the front wheels. The NSX Sport Hybrid power unit offers exceptional horsepower and torque with a broad powerband for tremendous throttle response and acceleration. Total system peak output is estimated at 573 horsepower—500 horsepower from the gasoline engine and 73 horsepower from the front TMU.
Twin-Turbocharged V6 Engine
Featuring a wide V-angle of 75 degrees to help lower the center of gravity, the NSX’s twin-turbocharged V6 engine achieves the best balance between power production, overall compactness and reduced mass. With a displacement of 3.5 liters, it combines both direct injection and port injection, along with Variable Timing Control (VTC) to deliver optimal camshaft phasing, for precision combustion control throughout the entire rpm band while simultaneously achieving high power output and performance at high engine speeds.
Making use of an electronic wastegate for each turbocharger for faster response as well as more precisely varying vane positioning, the single-scroll turbocharger design allows for the use of smaller turbos to reduce weight and improve packaging, while still meeting power and performance benchmarks. Furthermore, their single-scroll design allows for more efficient collection of exhaust as it escapes from within the cylinders.
To reduce the response delay that is associated with turbocharged powerplants, the rear Direct Drive Motor acts directly on the engine’s crankshaft and works in unison via a sophisticated algorithm to realize direct, high output, high torque acceleration performance. The enhanced efficiency of this design arrangement is particularly noticeable in normal everyday driving when accelerating from a low engine speed. Additionally, the rear electric motor also acts as a generator to provide supplemental power to the vehicles lithium ion battery pack, which also powers the front-mounted TMU.
Other key engine design elements include a sand-cast engine block, lightweight and compact cylinder heads, FC thermal spray coating on the engine block cylinder sleeves (for higher thermal efficiency, weight and compactness) and a dry sump lubrication system that significantly reduces the engine’s center of gravity—allowing 61 mm reduction from the crank center to the engine bottom versus a conventional wet sump—while ensuring effective lubrication at high cornering speeds.
The NSX has a compact valve train utilizing swing arm-type valve actuators, helping to reduce the inertial weight of the valve train and allowing a more compact head structure. The structure is similar to those found in some Honda racing engines. Intake and exhaust variable cam timing (VTC) is deployed to provide an excellent balance of high power, torque, fuel economy, and emissions.
9-Speed Dual Clutch Transmission with Direct Drive Motor
The new 9-speed dual clutch transmission works in concert with the engine and Direct Drive Motor to make full use of the power unit’s broad power band, producing lightning quick gear changes that support the NSX’s zero-delay response. As a key component of the Advanced Sports Package, the 9DCT has been optimized for compact size, low mass and low CG.
The 9DCT has a very wide ratio range that allows for optimal gear selection in all driving conditions. First gear ratio is configured for maximum vehicle launch acceleration, while the close-ratio gears (2nd through 8th) are perfectly matched to make the most of the power unit’s power band. Conversely, high gear (9th) has been optimized for fuel efficiency during steady-state highway cruising.
In efforts toward compactness and reduction of mass, the clutch and the differential are uniquely situated side-by side in a common housing. By adopting this design, overhang from the rear axle is minimized while the center of mass is moved forward.
Other advanced technologies incorporated into the 9-speed DCT are:
- Electronically-operated wet dual clutch, a high-rigidity shift fork, double-cone synchronizer, and an electronic shift actuator to more precisely synchronize power unit torque with shift timing for the quickest and smoothest shifts possible
- Precision surfaced high-efficiency hypoid bevel gear tooth shape for all gears for improved operation with reduced gear noise
- Addition of two oil “rooms” within the transmission housing for more efficient and higher-capacity cooling
- Clutch case and differential carrier integrated into the transmission for a more lightweight and compact structure
- Lightweight high-strength gearbox case
- Multiple-plate limited slip differential (LSD) provides increased traction when accelerating and cornering at the limits of adhesion
