- Direct Yaw Control – Sport Hybrid SH-AWD provides “active” all-wheel expostulate and extended doing capability around a energetic apportioning of TMU engine torque. The “direct bend control” of this electrified torque vectoring complement creates a bend impulse underneath any pulling condition to grasp a driver’s preferred cornering line.
- Instant, Powerful and Controllable Acceleration – Immediate and absolute acceleration G force from a impulse a motorist engages a throttle, extended by a present torque response of 3 electric motors operative in unanimity with a bespoke, twin-turbocharged V6 and lightning discerning 9-speed twin purchase smoothness (9DCT)
- Integrated Dynamics System – To softened entrance NSX’s ability to offer a driver’s desires, a Integrated Dynamics System uses 11 systems in 4 graphic settings that ring a widest operation of pulling needs.
Ultimate Structural Rigidity
Like a strange Acura NSX—the world’s initial all-aluminum supercar—the all-new NSX has a cutting-edge structure: a multi-material physique and space support implement new materials and construction methods to emanate a structure with rare energetic rigidity.
The ultra-rigid space support uses aluminum castings (shown in yellow) for all cessation ascent points.
- Unmatched energetic torsional rigidity – Directly responds to a driver’s cornering demands, now transmitting those inputs to a framework while progressing ideal tie between front and back axles, communicating both a driver’s transformation and any changes in a highway aspect with a rise fidelity.
- Ultra-high internal framework rigidity – Each framework member is mounted to a firm casting upheld by extruded aluminum support members that act like “truss structures” such that high internal connection area acerbity is ensured in all directions, assisting to say a precisely-designed framework geometry during all times.
Low and Centered Mass
The new Acura NSX “advanced sports package” is a pattern truth that seeks to optimize a pattern and wrapping of all vital automobile systems—the body, chassis, interior, Sport Hybrid appetite section (engine, Direct Drive Motor and 9DCT) and pivotal hybrid components including a Intelligent Power Unit (containing a lithium-ion battery pack), PDU and a TMU—to reduce and core a mass of a automobile for optimal doing and energetic response. The new NSX has a lowest core of sobriety (CG) among a core competitors.
The low CG and centered mass compensate dividends in doing and response. Biasing a mass toward a core of a NSX reduces a frigid moment, creation a automobile respond (yaw rate) faster to steering inputs and shortening a rotational kinetic energy. In other words, it’s easier to trigger a turn, and easier to stop a rotation. The low CG also reduces a energetic bucket transfer, so stabilizing a straight bucket on a tires.
The payoffs are discerning and accurate response to motorist inputs, minimal neglected physique movement, and fast tire grip—thus lifting a opening levels.
A Tight Grip on a Road
The NSX’s front double wishbone and back multi-link cessation systems were designed to support a impassioned energetic needs of this singular supercar, and work in ideal peace with SH-AWD and all other systems.
An modernized double-joint front cessation pattern eliminates torque expostulate and steering kickback. The back multi-link cessation provides high parallel acerbity to conflict steadily to motorist inputs and say stability.
Third-generation magnetorheological (MR) dampers invariably adjust damping army in fractions of a second, now bettering to a pulling situation, motorist inputs and highway conditions.
The complement maintains a accurate pattern geometry to remove a extent hold and control from a tires. Agile during low speeds, nonetheless magnificently fast and predicted during high speeds, a NSX steadily translates a driver’s inputs and always changing highway surfaces for ultimate doing performance.
Forged light amalgamate wheels with high parallel acerbity wrapped in 245/35ZR19 front and 305/30ZR20 back tires yield a NSX’s interface with a road. Standard high opening summer tires (Continental Conti-Sport Contact) yield glorious dry and soppy continue doing and traction. The multiple was tuned extensively in a dilemma bid with Continental to work in unanimity with a NSX framework and SH-AWD systems to offer aloft traction and grip.
Track-focused ultra-high opening summer tires, with towering hold levels and even aloft response characteristics are permitted as a play commissioned options.
The NSX employs a worldly dual-pinion (with rack-mounted support motor) electric appetite steering (EPS) complement with a non-static rigging ratio. When on center, a ratio is tuned for optimal high speed control and stability. Off center, a rigging ratio becomes gradually quicker for softened turn-in and maneuverability during low and midst speeds. The altogether discerning ratio effectively eliminates a need for driver’s hand-over-hand steering inputs.
High ascent and member acerbity minimize mislaid suit to assistance comprehend high steering correctness and true highway feedback. Steering support levels are mutated with a Integrated Dynamics System in unanimity with a MR dampers to yield suitable bid and highway feel for a preferred turn of performance.
Aerodynamic Balance High Speed Stability
NSX’s physique figure was effectively designed to minimize aerodynamic drag while formulating privately offset front-to-rear downforce by a sum airflow government proceed that focuses on utilizing airflow by any vent, while extracting extent appetite from a airflow margin to cold a brakes and appetite unit.
Extensive investigate and growth suggested that fixation approximately 3 times as many downforce during a back of a automobile relations to a front of a automobile provides a optimal downforce change for high-performance pulling as good as bland functionality.
Sport Hybrid Super Handling All-Wheel Drive
Sport Hybrid SH-AWD is a serve expansion of Acura’s rarely regarded Super-Handling All-Wheel Drive (SH-AWD) complement in vehicles like a Acura TLX sports sedan and MDX sport-utility vehicle. This rise new complement electrifies a torque vectoring ability and provides this ability to all drivers in all pulling conditions.
The NSX’s insubordinate Sport Hybrid SH-AWD uses torque vectoring-enhanced automobile dynamics—and privately proceed bend control—to ultimate advantage by utilizing a evident and “always-on” capacities of a electric motors to directly emanate a bend impulse during any speed, underneath power, and in off-throttle pulling maneuvers—with larger immediacy and precision.
Supported by a modernized yaw-control capabilities of Sport Hybrid SH-AWD, a NSX motorist is means to govern super-precise line tracing when aiming for a rise out on a lane or on a favorite circuitous road. What’s more, a motorist can do so with glorious automobile fortitude as good as a low workload, so expanding a capabilities of all drivers, trimming from beginner clubman to veteran racer in probably any pulling scenario.
When accelerating a complement provides evident torque response around a 3 electric motors—the Direct Drive Motor and front Twin Motor Unit.
While braking, a NSX employs both a robust automatic braking complement and a regenerative braking capabilities to broach powerful, accurate and probably fade-free stop opening with unequivocally healthy and on-going pedal feel while also recapturing kinetic appetite to assign a system’s lithium-ion hybrid battery.
When cornering, a NSX’s Twin Motor Unit and Vehicle Stability Assist (VSA) work cooperatively to raise cornering pointing (line traceability). If desired, VSA can be infirm by simply selecting a Track mode sourroundings of a Integrated Dynamics System, and afterwards holding a VSA “Off” button, located on a row to a left of a steering wheel, for during slightest 6 seconds.
By holding advantage of a evident high-torque response of a system’s 3 electric motors to worsen control, a Acura NSX Sport Hybrid SH-AWD complement elevates any driver’s certainty and opening pulling capabilities while extracting some-more opening from a automobile than is probable with required methods.
Next-Gen Supercar Power
At a heart of any supercar lies a absolute and manageable powertrain. The 2017 NSX raises a diversion by creation a extensive appetite now permitted and finely controllable.
Primary appetite is granted by a twin-turbo 3.5-liter V6 engine, with rise engine outlay of 500 hp and 406 lb.-ft. of torque during a driver’s disposal. Broad appetite and torque bands meant that this large ground force is permitted when a motorist unequivocally wants it. Dual electric rubbish gates assistance conduct boost law for well-spoken stifle transitions.
The new NSX’s 9-speed twin purchase smoothness also plays a essential role. Lightning-fast adult and downshifts delivered seamlessly make a NSX a fun to drive—the faster a better. The far-reaching sum ratio operation joined with closely spaced particular ratios supports extent descent of a twin-turbo V6 power. And a smoothness programming selects a right rigging during a right time, or lets drivers name as they wish.
The 9 DCT’s rigging ratio operation prioritizes extent
performance, with loose top-gear cruising.
But a genuine tip to a NSX’s probably zero-delay acceleration lies in a seamless formation of a present and estimable torque from a front TMU and Direct Drive Motor. This right now electric appetite pushes a NSX’s sum outlay to 573 hp and allows excellent composition of appetite for extent performance—on a travel or track.
Standing start acceleration G with far-reaching open stifle (WOT).
Importantly, a NSX’s control systems conduct a common complement appetite and torque uniformly while permitting scintillating response and acceleration. Responses can also be gradually quickened around Integrated Dynamics System settings.
Launch Mode Control
For ultimate, high-G acceleration from a standstill, a NSX motorist can plead Launch Mode Control. With a 9-speed DCT set in possibly Drive (“D”) or Manual (“M”) and a Integrated Dynamics System set to “Track” mode, a motorist depresses a stop pedal with a left feet while concurrently pulling a accelerator pedal all a approach to a building with a right foot. When a stop pedal is released, a NSX will perform a ideally executed launch that utilizes rise appetite from a TMU, twin-turbocharged V-6 engine and Direct Drive Motor.
Super Sports Brakes
Seamlessly integrating both automatic (friction) brakes with electro-servo control and a regenerative stop system, a NSX provides unusually precise, linear and probably fade-free braking opening in roughly any pulling condition. To support a motorist in high-speed pulling scenarios as good as during low-speeds, a absolute stop complement has been painstakingly tuned for easy, predicted modulation in any condition.
The Brembo mono retard stop calipers have been designed with high acerbity to yield even vigour placement and aloft pedal feel. Ultra-high opening and lightweight CO ceramic stop rotors are permitted as a factory-installed option. Both a CO ceramic and a customary iron rotors use a two-piece floating pattern to say unchanging interlude appetite underneath serious braking.
Dialing Up Dynamic Pleasure: The Integrated Dynamics System
The NSX Integrated Dynamics System provides a motorist with 4 selectable energetic modes—Quiet, Sport, Sport+ and Track. The complement integrates all of a vehicle’s energetic framework and powertrain systems—steering, brakes, throttle, automobile fortitude assist, magnetorheological dampers, engine, transmission, and Sport Hybrid SH-AWD control systems. From a permitted all-electric operation of Quiet mode to a sealed circuit, extent opening capacities of Track mode, a Integrated Dynamics System gradually dials adult a energetic characteristics of a automobile formed on a needs of a motorist and a pulling environment.
In serve to energetic complement variations, a Integrated Dynamics System varies cabin sounds around Active Exhaust Valve and Intake Sound Control to fine-tune sound peculiarity and volume to compare a energetic impression of a automobile in Quiet, Sport, Sport+ and Track modes. Notably, there is a full 25 dB sound turn disproportion between Quiet and Track modes—a extensive opposite in heard sensation.
The NSX Integrated Dynamics System also has a world’s initial tradition sourroundings menu that allows a motorist to configure a vehicle’s mode for startup. For example, drivers can module a automobile to always start in Quiet, or Sport mode, along with a ability to report a NSX to work exclusively in Quiet mode during a specified time period, such as a early morning to equivocate waking a neighborhood.
Integrated Dynamics System mode characteristics:
Quiet mode prioritizes electric-only pulling during reduce speeds, maximizing appetite potency and minimizing both cabin and extraneous noise. The automobile uses a TMU for initial launch from a standstill. When appetite approach requires a engine, it starts some-more sensitively than in other modes and extent engine speed is singular to 4,000 rpm, while a Active Exhaust and Intake Sound Control valves are sealed for a some-more inside operation. The smoothness change map also prioritizes reduce engine speeds. The motorist interface (tachometer and core console information arrangement screen) facilities a cold and still blue color.
Sport mode takes advantage of a Sport Hybrid complement to offer a motorist a proceed manageable automobile or a some-more loose automobile according to their pulling inputs. Compared to Quiet Mode, it eliminates a 4,000 rpm extent on a engine and quickens stifle response. A some-more assertive smoothness change map binds gears longer and allows aloft rpm change points. The Intake Sound Control complement and a Active Exhaust Valve are activated, permitting additional intake and empty sound to interfuse a cabin for a some-more romantic pulling experience. Like Quiet mode, Sport mode provides idle stop function. The Sport mode is a default sourroundings in normal automobile operation.
Sport+ serve prioritizes drivetrain response and energetic opening with faster up- and down-shifts of a 9 DCT and still some-more assertive stifle mapping. Maximum use of a electric engine torque provides some-more bomb acceleration. Increased lively is achieved by harmonizing a some-more assertive Direct Yaw Control sourroundings that works in unanimity with a magnetorheological dampers, Agile Handling Assist, and a Electric Power Steering system—perfect for a energetic expostulate on a circuitous road. It also transmits a aloft grade of steering feedback, while intake and empty note sounds are serve increasing for an even some-more refreshing pulling experience. The TFT Meter sports an assertive yellow “con-trail” along a tachometer needle ancillary easy approval of engine RPM. Red highlights for a core console information arrangement also strengthen that a motorist is in now in Sport+ mode.
Optimized for circuit driving, Track mode invokes a many assertive settings and parameters to support a motorist in capturing a fastest and many unchanging path times possible, along with extent acceleration from a delay when utilizing Launch Mode Control. The braking complement offers extended performance-oriented pedal feel. Up/down gearshift execution of a DCT and opening of a Super Hybrid SH-AWD and active motorist aids (VSA, AHA) are automatic to support circuit extent driving, and an even larger volume of engine intake sound permeates a cabin for a heightened pulling knowledge charity extended motorist feedback even when wearing a helmet.
Track mode also prioritizes a lithium-ion battery state-of-charge to say a unchanging turn of torque smoothness and proceed bend impulse from a 3 electric motors.
Of note, a VSA operation is gradually “loosened” from a Integrated Dynamics System Quiet mode adult to Track mode, enabling an increasingly aloft grade of leisure for a motorist in exploring a energetic capabilities of a NSX. In “Track” mode, a VSA complement can also be totally infirm by a driver.
