The next Honda NSX has been revealed, along with its all-new power unit – a twin-turbocharged V6 engine with a 9-speed dual clutch transmission (DCT) and three-electric motor Sport Hybrid system.
The V6 engine employs a race-inspired compact valve train and dry sump lubrication system to help lower the centre of gravity. The all-new 9-speed DCT delivers rapid gear changes and rev-matching downshifts. The rear direct-drive electric motor is housed between the engine and transmission. The NSX’s front wheels are driven by twin independent high-output electric motors which deliver instantaneous torque response and dynamic left-to-right torque distribution.
The NSX uses its front electric motors for dynamic torque vectoring in addition to enhancing acceleration and braking performance. The result is an instantaneous “zero delay” launch performance and handling response.
The new NSX features an innovative new multi-material body design with world-first material applications and construction processes. The NSX body utilises a space frame design—an internal frame constructed of aluminum, ultra-high strength steel and other advanced materials. Anchored by a carbon fibre floor, torsional and bending forces are taken up entirely by this ultra-rigid structure which also utilises advanced joining technologies.
The NSX features an “Advanced Sports Package” with placement of key powertrain components – the mid-mounted engine, twin front motors and Sport Hybrid battery pack and power control unit – optimised to concentrate vehicle mass low and toward the centre of the vehicle, to further enhance dynamic response. The combination of this packaging concept and the lightweight body give the NSX the lowest centre of gravity in its class.
Handling is enhanced by Sport Hybrid Super-Handling All Wheel Drive (Sport Hybrid SH-AWD), enabling quick responses to all driver inputs – steering, braking and throttle – along with the stability, control and launch performance of all-wheel drive. Agile Handling Assist (AHA) uses the subtle application of brake torque to further enhance yaw response and dynamic stability.
The NSX’s dial-operated Integrated Dynamic System features Quiet, Sport, Sport+ and Track modes. The system adjusts engine, motor, transmission and chassis response, as well as the engine sound level, based on the needs of the driver and driving environment. Quiet mode enables electric-only driving at lower speeds for short durations. Dynamic vehicle responses become increasingly sharp as the driver moves from Sport to Sport+ mode and, finally, to Track mode, where the NSX reveals the full spectrum of its performance capabilities.
The NSX also features a “launch” function to achieve the ultimate in “zero delay” launch performance, aided by both the engine and three electric motors.
The Honda NSX goes on sale in mid-2015.
