New photos and complete spec sheet for the 2017 Acura NSX were released today. Mechanically, this is one complicated hybrid sports car that carries a hefty price tag of around $155,000 – $170,000 according to Motortrend and Autoblog.
Power is derived from multiple sources and probably explains why this low-slung sports coupe is 3,800 pounds, which is nearly 300 pounds heavier than a BMW M4. Combined power from a twin-turbocharged V6 engine and three electric motors sum up to a grand total of 573 horsepower. Dynamic power from gasoline engine and electric motors are sent through a 9-speed dual-clutch transmission and limited slip differential, driving all four wheels.
The driver has the choice of four selectable dynamic modes through the Integrated Dynamics System (IDS). The system controls the NSX’s dynamic chassis and powertrain systems — steering, throttle response, vehicle stability assist, magnetorheological dampers, engine, transmission, brakes, and Sport Hybrid SH-AWD systems.
Quiet mode prioritizes electric-only driving at lower speeds, maximizing energy efficiency and minimizing cabin sound. The vehicle uses the TMU for initial launch from a standstill. When power demand requires the engine, it starts more quietly than in other modes and maximum engine speed is limited to 4,000 rpm, while the Active Exhaust and Intake Sound Control valves are closed for a more hushed operation. The transmission shift map also prioritizes lower engine speeds.
Sport mode is the default setting and behaves complacently for normal driving on the street. Compared to Quiet Mode, it eliminates the 4,000 rpm limit on the engine and provides a more aggressive throttle map for quicker response. A more aggressive transmission shift map holds gears longer and allows higher rpm shift points. The Intake Sound Control system and the Active Exhaust Valve are activated, allowing exhaust and intake sound to permeate the cabin.
Sport+ is where the fun begins and untaps the hidden potential that the Ohio engineers worked so hard to get right. It prioritizes maximum drivetrain response and dynamic performance with faster up- and down-shifts of the 9-speed DCT and more aggressive throttle mapping. Maximum use of the electric motor torque provides more explosive acceleration. Increased handling dynamics is achieved by bringing together a more aggressive Direct Yaw Control setting that works in concert with the magnetorheological dampers, Agile Handling Assist, and the Electric Power Steering System. It also dials up steering feedback for the driver, and volume of intake and exhaust note sounds via Active Sound Control. The TFT Meter sports an aggressive yellow “con-trail” along the tachometer needle supporting easy recognition of engine RPM. Red highlights for the center console information display also reinforce that the driver is in now in Sport+ mode.
Track mode invokes the most aggressive settings and parameters to deliver the fastest and most consistent lap times possible, along with maximum acceleration from a standstill when utilizing launch control mode). The braking system becomes more consistent and linear for better modulation of the brakes. Up/down gearshift execution of the DCT and performance of the Super Hybrid SH-AWD and active driver aids are programmed for maximum performance where wearing a helmet is a requirement.
This setting also prioritizes the lithium-ion battery state-of-charge to maintain a consistent level of torque delivery and direct yaw moment from the three electric motors to ensure consistent dynamic response and lap times.
