How fat is your car?

Our second problem is the Stig. Or, rather, lack thereof. Our tame racing driver is nowhere to be found. Maybe our choice of car simply hasn't triggered his radar: yes, the Peugeot 207 GTI is, technically, a hot hatch, but it's not a very Stiggish hot hatch. Too wallowy, too soft, too... fat. Not that the 207 GTI is in any way unique for being a bit of a porker. It's indicative of a general trend towards portliness, but thanks to its nimble ancestor the 205 GTI, the weight gain here seems more heinous than it does in its many blubby rivals. According to official figures, the old 205 GTI tips the scales at 900kg with a power-to-weight ratio of 149bhp/tonne. The 207 GTI is just over 1,300kg with a power-to-weight ratio of 133bhp/tonne. Oh dear. This is why we've chosen the 207 as the guinea pig for our quickfire diet strategy.
