Top 100: Biggest AC-Drive Truck

The B Series of Liebherr's T282 haul truck jumped 40 tons to a nominal payload rating of 400 tons with the use of the new 56/80R63 tires and the 3,650-hp MTU20V4000 diesel engine (adding nearly 1,000 horsepower). It's the biggest AC diesel electric-drive mining truck — with the largest nominal payload and most horsepower — available today. Top speed remains 40 mph, but the more-powerful engine accelerates the truck faster and maintains greater haul speeds on grades. Estimated list price: $3.5 million.
