Back in April, Porsche tuning specialist, 9ff , made a world record attempt for the fastest production car with their 987bhp GT9 but came up a bit short at 409 km/h. Currently the record to beat is the SSC Ultimate Aero TT with 412.28 km/h ( 256.18 mph). However, it seems 9ff's work with combining high performance Porsche's with alternative fuel, as displayed with their E85 bio-ethanol fuel 9ff Porsche Cayman CT-78 with 780 hp could be a more successful road worth traveling for the Dortmund based tuner. German car magazine SportAuto conducted a readers polls which contained 14 categories for series-production vehicles and 11 tuning classes. With more than 10,000 readers taking part, they awarded the CT-78 as the sportiest tuned coupe beyond EUR 80,000. In times of the CO2 discussion, this is a particularly valuable distinction.
