Hartge builds 300+km/h LPG BMW 1-seriesEnlarge Photo
The land-speed record for an LPG vehicle was achieved by the IdéeVerte Compétition, an aerodynamic racecar that went on the reach 315km/h in 2004.
The Hartge LPG 1-series was co-developed with the help of several experts from the University of Technology and Economics in Saarbruecken, Germany, and is designed to showcase the performance potential of the alternative fuel. LPG reportedly burns much cleaner than petrol and diesel and in some cases produce more power and torque. Hartge also has a V8 powered 1-series that runs on regular petrol but "only" delivers 450hp.
