Honda’s head of analysis and growth, Sekino Yosuke, has revealed the next-generation Honda NSX might be based mostly on the agency’s 1,000 hp Pikes Peak race automobile, the NSX-inspired Four-Motor Acura EV Idea.

The Four-Motor Acura EV completed third general on the Pikes Peak hill climb in 2016. That was due to its all-electric all-wheel-drive powertrain, comprising 4 electrical motors that developed round 740 kW and 800 Nm of torque with a 70 kwh lithium-ion battery pack and a kerb weight of just one,500 kg. Honda claims the electrical NSX is able to Zero-100 km/h in 2.5 seconds and Zero-200 km/h in 6.2 seconds.

With the present all wheel drive hybrid NSX having solely been on sale since final 12 months, an all-new NSX is unlikely to be launched earlier than 2023, when battery know-how is anticipated to have progressed considerably.

Honda first demonstrated a Four-Motor EV CR-Z prototype in 2015 with journalists who check drove the car suggesting torque vectoring gave it cornering potential in a complete different league to a Mannequin S.

Whereas there is no denying Tesla, particularly with ludicrous mode, have re-calibrated the auto-industry’s definition of ‘fast’, it is most likely much less well-known that Tesla’s powertrain is definitely based mostly on 1990s know-how with the three part AC induction motor and controller designs initially licensed from EV1 drive system engineer Alan Cocconi.

In contrast to present excessive efficiency all-wheel drive electrical automobiles, like Tesla’s Mannequin S P100D, which use 2x electrical motors and standard mechanical differentials, Honda’s electrical NSX options 4 electrical motors — one for every wheel.

With a devoted motor at every nook, the Tremendous Dealing with All-Wheel Drive (SH-AWD) system can exactly apply both optimistic or damaging torque individually to every wheel. This opens the door to torque vectoring and full-time energetic yaw management – one thing that can make shopper EVs safer and extra vitality environment friendly.

How does this work? Think about digital stability management that, as a substitute of making use of friction brakes (wasted vitality), applies damaging torque (regenerative braking) to particular person wheels. In contrast to friction-brake based mostly ESC, the NSX Four-Motor system also can apply optimistic torque to particular person wheels. Not solely that however optimistic and damaging torque will be utilized concurrently throughout the car adjusting pitch, roll, and yaw to precisely place the car alongside any vector. Combining that vary of exact management with a multi gyro inertial measurement platform unlocks a completely new stage of security and excessive efficiency energetic dynamic management.

Whereas it could be one other 5-6 years earlier than Honda’s Four-Motor Tremendous Dealing with All-Wheel Drive makes it into manufacturing, the workforce at Evans Electrical are creating an AWD torque vectoring system based mostly on compact Axial flux induction motors.
