It’s high time for a Japanese supercar smackdown, and we present a good one on this episode of Head 2 Head, presented by Tire Rack! (http://www.tirerack.com ) Ever since the Nissan GT-R finally came to America for the 2009 model year, it’s lacked a hometown rival. For 2017, Godzilla gets a refresh just in time to do battle with the brand-new Acura NSX. The NSX is a rolling tech showcase, combining a mid-mounted, twin-turbocharged, 75-degree, 3.5L V-6 and (for the first time ever) two electric motors up front, providing real torque vectoring across the front axle. It also features a third electric motor sandwiched between the gasoline engine and a nine-speed dual-clutch automatic to provide torque-fill, boosting output while the turbochargers are spooling up. This new tech makes the GT-R sound decidedly old-school—its front-mounted, 3.8L twin-turbo V-6 mates to a six-speed dual-clutch automatic, with no electric motors to help it out. MOTOR TREND Senior Features Editors Jason Cammisa and Jonny Lieberman discuss the two supercar slayers before handing the keys over to SCCA Hall of Fame driver Randy Pobst to lap them both around Mazda Raceway Laguna Seca. Which is quickest? Which is best? As always, there’s only one winner on Head 2 Head.
