€198,900 buys Bovensiepen’s new 05 GT, a Frank Stephenson-styled BMW M5 Touring remake that adds a subtler exterior, more leather-lined cabin and grand-touring-focused chassis tuning.
790 horsepower and 1,100 Nm come from revised software, a new air intake and an Akrapovič titanium exhaust, lifting output 73 hp above the donor car while BMW’s EU-spec M5 stays at 717 hp.
21-inch forged wheels, Eibach springs, new Pirelli tires and a split rear spoiler are part of the package, though the wagon still weighs 2,555 kg in European specification.
Q4 deliveries are planned in Germany, with the 05 GT priced €51,700 above a base M5 Touring as the Bovensiepen family pushes ahead with post-Alpina models under its own name.
