2011 Nissan GT-R:
This was the car that I was the least excited to write about; it's big, heavy, and the GT-R is essentially an overpriced Nissan coupe--more like a bad rip-off of a Skyline--that is not terribly faster than Lexus' limited-production LF-A, yet is powered by a 3.8 liter, twin-turbo V6, a hand-crafted, 24-valve engine that puts-out 530bhp at 6400rpm.
Though hand-crafted with care in a sterilized environment and as fast off-the-jump as the LF-A, Nissan's GT-R was produced in limited numbers for 2011, and with the "Basic" model being completely dropped for this sales year, the "Premium" trim became the standard for all GT-R owners.
2011 Dodge Challenger SRT8 392:
For 2011, Mopar made just as much of a "muscle car comeback" as did Chevy with the '11 Camaro SS, especially the convertible version. But Mopar, possibly even more than a year before Chevy was to announce the ZL1 Camaro for 2012, stepped-up the bar on late-model cubic inches, punching out the then-current SRT8's 6.1 Hemi out to a 6.4 liter, or a 392-cube motor.
The result was substantial, as Chrysler's 392 cubic-inch Hemi V8 was now capable of producing 470bhp at 6000rpm, while max torque was 470 foot-pounds at 4200rpm; these figures represented a 45-horsepower increase with 50 more foot-pounds of torque, producing peak power at 200 revs lower than before, with peak torque being produced 600 revs lower than the previous Hemi.
2011 Shelby Mustang GT500:
Ford, with the Mustang in particular, has always been notorious for offering various performance packages for their "prized pony." It's true for the "Blue Oval" and has always been, especially when combining forces with legendary builder/tuner, Carroll Shelby.
A bad-ass, late-model racer, Shelby's GT500 is powered by an all-aluminum V8 with a wet sump that is based on the Ford GT's dry-sump motor, except that the block is different, despite the fact that both motors are aluminum.
From the 2010 GT500, the all-aluminum V8 in the 2011 car replaced the previous cast iron block, shaving 102 pounds from the nose and 120 pounds overall.
2011 Pagani Huayra:
A car of which not too much can be said, the Huayra from Horacio Pagani is a Lamborghini derivative, as Pagani himself is a former employee, and it is one of those fast supercars that has made it successfully as an AMG-Mercedes "lovechild."
Powered by AMG's stout V12, the Pagani Huayra is more of a "designer label" supercar, concentrating much more on styling and carbon construction then on brute, FIA-friendly horsepower.
2011 Ultima Can-Am:
This one goes without any introduction, except that it must be the best example of a V8 road car that our generation has seen.
