We first drove the 2010 Shelby GT500 on sunny California's dry, smooth roads. This time, it was in the northeast during equal spells of sun and rainy, cold October days. Does our initial reaction of delight still hold true?

The biggest difference between this 2010 and the old model first introduced in 2007 isn't the power and torque bump (from 500 HP and 480 Lb-Ft to 540 HP and 510 Lb-Ft), but rather the fitment of better suspension and particularly a whiz-bang stability control system that doesn't just make driving the live rear axle muscle car safer, but also much faster.

How does it do that? Not just by controlling wheelspin on the rear axle due to an overly enthusiastic right foot, but also by reigning in understeer. That means you can hold a tighter line in corners which, in turn, means you can go faster.

The system's got three modes: everything on, traction off, and full traction and stability off. It's that middle mode that you'll want to drive the GT500 in most of the time. It allows seven to eight degrees of rear wheel slide before intervening to stop you slamming into a tree. Yes, your ability to posture masculinely on the internet is reduced by admitting you use stability control, but it's just way more fun to drive the car like this. Not only because the car doesn't understeer so much, but also because you're free to really beat on the engine without worrying too much about bodywork repair bills.
