Overview
- Bovensiepen revealed the 05 GT as a limited-production plug‑in hybrid Gran Turismo built on the BMW G90 M5/5‑Series Touring with a stated combined output near 589 kW (roughly 800 hp) and 1,100 Nm of torque.
- The firm credits a revised intake, Akrapovič titanium exhaust and engine software recalibration after testing at Papenburg and Nardò for the power increase and a claimed 0–100 km/h time under 3.6 seconds.
- Exterior and interior work was led by Frank Stephenson’s team at Bovensiepen’s Buchloe facility, with new front and rear bodywork, 21‑inch forged wheels, and a range of bespoke Lavalina leather options priced as a €20,000 upgrade.
- Key supplier hardware includes an Akrapovič titanium exhaust, custom Pirelli tires, and Eibach springs, and each car will carry a numbered production plate as part of a roughly 200‑car‑per‑year run.
- Bovensiepen lists the 05 GT from €198,900 in Germany and aims for first deliveries in Q4 2026, positioning the car as a handcrafted, higher‑priced alternative to factory M5 models that keeps some G90 door skins unchanged because the platform was not widened.
