London, Londo United Kingdom (PressExposure) July 01, 2009 -- Audi A4 panted and blew away the bio-gas world speed record by reaching an astonishing 226.6mph. Boffins at the Community Centre of Excellence in Germany built this modified Audi A4 to run on bio-gas to show the world the power of earth-friendly fire.
The Audi A4 car feels composed at speed, and rarely gets caught out by sharp bends or unforgiving road surfaces. The ride is also excellent, soaking up bumps with ease, but never at the detriment of comfort.
Using technological wizadry and a fair amount of smelling salts (methane stinks), the engineers managed to achieve an incredible 700bhp from the Audi's twin-turbocharged 3-litre V6 engine.
Audis have an excellent reputation for reliability, and the new A4 seems among the most solid the manufacturer has built. The Audi A4 is traditionally one of the top 30 most reliable cars of the past decade, according to the Reliability Index.
They reckon the engine could produce up to 800bhp but limited the power to save the transmission. Think about it - a green Audi A4 with enough firepower to nuke a Koenigsegg.
