Nissan GT-R

Four-Wheel drive, 545 horsepower, double wishbone suspension, and a fine-trimmed body to boot. My brother calls it the 'neck-breaking car' because of the G-forces applied to your neck when you're cornering. There's actually a screen, which is partially dedicated to measuring G-forces, in the cabin.
