The Terex Titan was a Canadian earth-hauling truck prototype built by the Terex Corporation then of General Motors. It had an empty weight of 235 tonnes, and a maximum loaded weight of 550 tonnes. It was powered by a 169.5L (10,343 c.i.) 16 cylinder 3300 hp (2,460 kW) engine coupled to a generator. The generator then powered 4 electric traction motors located at each rear wheel. It is 66 feet (20 m) long and 22.6 feet (6.9 m) tall. It is 56 feet (17.1 m) tall with the dump box extended. Built in late 1974 at GM's London, Ontario Plant, it was to undergo 12 months testing in California. In 1978, it was assembled in Sparwood BC for Kaiser Resources Ltd. It was retired from service at a coal mine in 1990 and is now located in Sparwood.
The engine has since been removed. The modern Liebherr T 282B truck has slightly smaller dimensions and smaller mass, but larger load capacity and a more powerful engine. Unlike the Titan, it is a normal, commercially available model, rather than a prototype.
