Toyota's all-new 4.6-liter i-Force V-8 comes in,  2010 Tundra. It's smaller than the 276-horsepower, 4.7-liter V-8 (313 pounds-feet of torque) it replaces, but stronger, lighter and more efficient. The new engine is paired with a new six-speed automatic transmission, and together they're expected to get up to 20 mpg on the highway.
