6. Holden UTE SSV
The Australian Holden Ute is a popular light-duty pickup featuring a passenger car chassis and engine but the payload and practicality of a truck. To further develop the concept, the engineers from Holden decided to install the biggest engine they could find. And doing so produced an insane truck with a 6.3-liter V8, 421 HP, and rear-wheel drive.
They named it the Holden Ute SSV, a fully GM product because the platform was already in some U.S. models. In fact, the engine was in the Corvette, for example. However, GM decided to leave this model in Australia even though most people think it would be popular in America.
