The teasing was long and arduous, and at some point, it might have been even a little too drawn out. But finally, the Mosler Raptor GTR is getting ready to draw its claws and show off its fangs.Once teased as the Mosler Raptor, this Florida-based supercar has officially taken the name ’Raptor GTR’ and true to all our expectations, it really does pack a wallop.The cheesy introductory video featuring model Abby Cubey didn’t do it any real favors as far as first impressions go. But once you get past that, the sheer performance numbers of the Raptor GTR will surely make you stand up and take serious notice.The American supercar will be carrying the long-rumored 7.0-liter twin-turbo V8 powertrain. But instead of carrying 650 horsepower, the Raptor GTR will be unleashing a chilling 838 horsepower from under its hood. Together, the supercar’s massive powertrain and its carbon fiber body and chassis weigh in at only 2,580 lbs, ensuring that the Raptor GTR will be able to deliver a power-to-weight ratio that’s 36 percent higher than the Bugatti Veyron. All that translates to a 0-60 mph time of just 2.6 seconds with a top speed of 240 mph.About the only downside to the Raptor GTR, at least as far as our bank accounts are concerned, is that it comes at a jaw-dropping price of $700,000. But if that’s within you price range - and you’re not cool with "just" 838 ponies - Mosler will be offering 12 buyers a $70,000 CubeyGTR upgrade package that brings the output to well over 1,200 horsepower, with a 0-60 mph time of just 2.2 seconds.
