Why it matters
The Sirius was built by tuner and race-car constructor Kurt Lotterschmid to be the fastest two-seater with road registration. Its figures of 1200 PS and a claimed top speed of up to 400 km/h put it among the extreme road cars of its time, produced by a very small workshop.

02Production & history
Production
Every figure says what it counts.
No production figures recorded yet.
History
Spiegel reported in May 2001 that wiring of the car was finished and testing could begin, with a development cost the builder put at six to seven million marks. The styling came from chipboard silhouettes shaped with an angle grinder. The mid-mounted engine is a tuned Mercedes-Benz 6.0-litre V12 with two turbochargers.
Lotterschmid had wanted to build a small series of 20 with Chinese business partners, but disagreements prevented it, and the Sirius stayed a one-off.
