As if its “Quiet Mode” didn’t make the 2017 Acura NSX stealthy enough, Honda has decided to rip out its twin-turbo V-6 for a second pair of electric motors and a larger battery to race up Pikes Peak.

The NSX EV Concept does not presage a production model being developed for sale. It will be challenge enough to move a couple hundred of the gas-electric Acura supercars each year when snorty rivals like the Aston Martin Vantage and Porsche 911 Turbo retail for similar prices. Instead, armed with a squirrel-scooping front splitter and vicious dive planes, this lightweight NSX was devised specifically to tackle the Pikes Peak International Hill Climb on June 26. Japanese Super GT champ Tetsuya Yamano will take the wheel in the Electric Modified class. Going all-electric for Pikes Peak is a neat inversion of Acura’s GT3 road-racing program, which ditches the hybrid elements of battery-pack and electric motor to go with traditional internal combustion alone. Honda won’t say anything about the NSX EV powertrain except that it has four electric motors, a setup used on the CR-Z EV race car the company fielded for Yamano to drive at last year’s event. The company says that this NSX EV generates three times more power than did the CR-Z?which, based on a detuned version that Honda let journalists drive last year, we can only assume means something north of 600 horsepower. There are no hub motors in play here, just a heavy-duty version of the electri...
