Retro-style automaker Wiesmann is celebrating its 20th anniversary with a limited-edition GT MF4-S.

The closed two-seater is powered by a BMW-sourced 4.8L V8 engine but output has been lifted to 420hp (309kW) – the standard GT MF4 produces 367hp (270kW).

This pretty coupe comes with the option of six-speed manual or dual-clutch auto transmission, and unique upholstery and instrumentation.

In addition to the more powerful engine, the interiors come with the usual personalized owner’s name engraving and production number, and special embroidered seats.

Only 30 examples of the MF4-S will be offered, but Wiesmann is expected to follow it with two more special editions before the birthday party is over. It will be unveiled at the Geneva Show in March.

Founded in 1985 by brothers Martin, an engineer, and Friedhelm, a businessman, Wiesmann got its start building hardtops for convertibles.

In 2006, however, the Brothers Wiesmann came out with their own vehicle a curvaceous and retro coupe and roadster. Via Motorauthority / Classiccar
