Up in smoke: Tunit the tuning people run comparison fuel tests on three popular tuned cars, with the newest premium fuel against lower-cost formulations

摘要

Rarely do we have the opportunity to see three tuned cars in action in just one day. But this was no normal day - it was one of the nastiest days weather-wise that even Lancashire can offer, which left not even the slimmest opportunity to road test the cars in question due to dense fog and driving rain -or even to take any pretty pictures framed with blue skies, puffy clouds, and sunshine! But there was plenty of lively action on the Tunit rolling road dynamometer! So read on and follow the gripping story of what happened when the BMW, the Focus, and the Golf all strutted their stuff on the Tunit dynamometer-and then went off to the Filling Station! Tunit, like any engine manufacturer, need to test its products fully to ensure that they work with different conditions and other variables, and that means things like fuel quality-a subject about which there's plenty of discussion and strong opinion. In this case we were invited along to witness some eye-opening comparison tests using premium and non-premium fuels and to observe the results as effectively independent witnesses.
