How do you build the world's quickest car? Well, first you take one of the quickest cars already on the road, then you add more power and charge millions for each example.
In this case, chauffer Marlon Kirby and financier David McMahan took the Ultima GTR – which already claims the fastest quarter-mile, 0-100-0, Nürburgring (almost) and Top Gear (unofficial) track times – and dropped in an all-aluminum 7.0-liter Chevy small-block V8 with twin turbochargers to bring the power rating up to 1600 horses, calling the resultant monster the Maxximus G-Force. All those ponies drive through a three-speed sequential gearbox, while six-piston AP Racing calipers gripping 14.2-inch discs handle the stopping power.
Housed in a 2700-pound frame, that's apparently enough to get the G-Force up to 60 miles-per-hour in 2.1 seconds, to 100 mph in 4.5 seconds and run the 0-100-0 sprint in 8.8 seconds. Nine minutes of fuel is all it can carry at those rates, but considering that McMahan and Kirby are charging $3 million a pop, we doubt a big bill at the gas pump would be an owner's biggest concern.
