Rumor: Honda targets 23.5mpg efficiency for upcoming 500+hp V10

 Credibility Rating: 6


Winding Road reports that the latest rumors in Tokyo concerning the next-gen NSX's development path indicate that Honda's aiming for the all-new naturally-aspirated V10 motor (rumored to displace 5.0L and develop 500+hp) to deliver 10.0km/liter (approximately 23.5mpg).

In theory, it shouldn't be super difficult to hit that mark (at least on the Highway portion of the US's EPA ratings) - Chevy's already done it with the 505hp 7.0L LS7 monster that powers the Corvette Z06 with a highway rating of 26mpg. The secret: super-tall gearing for the top two cogs (6th is 1:2) resulting in a cruising rpm that's only a few hundred rpms above idle. Another advantage to the Z06 is that it only weighs in at a shade over 3100lbs. With an SH-AWD drivetrain we can only pray that the NSX even approaches that number.

As pointed out by 'danielgr' in the comments below, though, Honda's mileage target is most likely aimed at Japan's 10-15 combined mode. In other words, not as "easy" as achieving a big number on the EPA's Highway ratings.

UPDATED to reflect input from 'danielgr' regarding Japan's 10-15 combined mode
