Bring out your best Tim Allen imitation:
more power, ar ar ar! It's the world biggest truck, the Liebherr T 282B. It hauls 400 tons at a time via a 3650-horsepower engine.
The engine doesn't turn the wheels, oh no, that would be too simple; no, instead it generates AC power, which turns an electric motor attached to the rear axles. Using this method it goes up to 40 miles an hour (60 kph). It's used in mining.
It costs $3M and they will sell fewer than 100 a year.
