The DC Design DC Star from 2005 was a custom two-door version of the first-generation Porsche Cayenne Turbo S created by Indian coachbuilder DC Design. Rather than being an official factory concept from Porsche, it was a coachbuilt showcase built around the Cayenne Turbo S platform and shown at events like the Dubai Auto Show. The DC Star took the normally four-door Cayenne SUV and reworked it as a two-door, more dramatic body style with bespoke exterior and interior touches

The Renault Clio V6 concept, first shown in 1998, was a preview of a wild mid-engine version of the Clio hatchback. The idea later became a limited-production model, built between 2001 and 2005, with the engine mounted behind the seats and power sent to the rear wheels.

The MG XPower SV-R, released in 2004, was the top-performance version of the XPower SV. It was powered by a Roush-tuned 5.0-liter, 32-valve Ford Modular V8 that made a claimed 385 hp. Only 82 XPower SVs were built in total before MG Rover went into receivership in 2005. The exact number of SV-R versions is unclear, but only a small portion of the total production were SV-Rs, making them especially rare.
