Mario Minichberger spent five years building the Minichberger Motorsport BMW 2002 for hillclimb racing. The race car is not powered by a 2.0 L M10 inline-four. In the engine bay sits a naturally aspirated 2.0 L M12/7 inline-four. 19Bozzy92 reports the motor produces 320 hp at 10,800 rpm. The channel also states the car weighs 800 kg (1763 lb) thanks to a full carbon fiber widebody. Watch Mario compete in the first round of the 2024 Swiss Hillclimb Championship (Schweizer Bergmeisterschaft) at Bergrennen Hemberg.
