A biofuel-powered Audi A4 raced to the top by becoming the fastest car that can be fueled with the said gas. The 700hp 3.0-litre engine is capable of a top speed of 364.6 km/h (226.55 miles/h).
Although there have been many attempts, this one is the first to succeed. A modified Audi A4 is the fastest car to be powered by biogas. Biogas can produce between 120-140 octane ratings, which is a lot more power than premium pump gas. Jurgen Hohenester, a German tuner and racer, was behind the wheel. Hohenester was able pilot the car at a speed of 364.6 km/h (226.55 mph), at the Papenburg racetrack in Lower Saxony. Guinness World Records approved the record.
The A4 Hohenester Sport, or HS 650, is powered by the 2002 Audi B5 S4 V6 engine, but the capacity has been increased from 2.7-litres to 3.0-litres. It is 20 km/h slower than the Bugatti Veyron, which was the previous record holder for this category.
The HS 650 can produce over 800hp (588kW) under normal conditions, but it is limited to 700hp (515kW) for structural preservation. This is a significant improvement on the 265hp (295kW) that the biturbo 2.7-litre used to produce in its prime.
According to Dr. Behrning from TUV Rheinland, the record proves that biogas is an alternative to fossil fuels. Next up is a win overall at the Tuner Grand Prix Hockenheim.
