Are you one of the lucky owners of the 2015 Volkswagen GTI ? If yes, you should be happy, because your 210- or 220-horsepower hot hatchback might actually have more like 260 ponies under its hood.That's according to a dyno test from a vendor on, of all places, a Ford Focus ST enthusiast forum . The company is estimating a 15-percent drivetrain loss with the GTI's best result a whopping 263 horsepower and 314 pound-feet of torque at the crank. That's a tremendous difference from the 210 hp and 258 lb-ft of torque that Volkswagen claims.Of course, this is merely one dyno session on one car. We'll have to wait until more 2015 GTI owners get on the rolling road to see if Volkswagen really was as conservative about its hot hatch's output as FocusST.org claims
