Jonny Lieberman has a go with perhaps the most capable grand touring car on the market, the new Porsche 911 Turbo S. Combining 560 horsepower, upwards of 553 lb-ft of torque and several cows' worth of leather. Embarking on a cross continental trip in the dead of winter, Jonny begins in frosty Georgia and heads all the way back to Motor Trend's headquarters in Southern California.
