Any talk of Tundra performance must focus on its excellent new powertrain. With six gears, 381 horses and 401 lb.-ft of torque, there's plenty of low-end grunt and fast starts, thanks to a low first gear. Punch the throttle and you get what you pay for: A controlled surge of power and smooth, aggressive gearing built more for performance than for saving gasoline. To that end, Toyota reports an EPA rating of 14/18 in the 5.7-liter V8 powertrain. With so much thrust early, passing is easily handled: Goose the accelerator at speed and the Tundra sits up, collects itself and rumbles to life. Brakes are big, grab tightly and, though we felt a little too much pedal play, stop the Tundra promptly.
