Toyota TS020/GT-One (1998)
If you thought the 250 GTO was stretching the rules, get a load of the Toyota GT-One. Built to exploit every loophole they could find, the short lived GT-One tried to take on the fearsome CLK GTRs and 911 GT1s of the late-90s GT circuit.
Two road-going versions were built, but don’t expect to find videos of them topping 260 MPH any time soon. The homologation cars were built to qualify and never actually sold. If do you ever manage to snag one from Toyota, be forewarned. The FIA never specified that an empty fuel tank couldn’t count as the luggage space.
Lancia Delta S4 Stradale (1985-1986)
It may look like a piglet, but this boxy little four-banger is one of the maddest homologation cars of them all. When Lancia’s engineers decided that turbo lag had no place in their new Group B rally car, they squeezed a supercharger underneath the turbo to pick up the low-rev slack. The result was a ludicrous twin-charged engine. The 1.8-liter I4 was capable of pushing anywhere from 250 to 1,000-plus horsepower in testing.
The homologation version wasn’t tuned quite as violently as the Group B car. However the Stradale kept the engine in the back seats and brought twin-charging to public roads for the first time.
