MPG and running costs
A lithe kerb-weight and super efficient engines help the 308 achieve some pretty impressive numbers on paper, but on the road the super efficient options don’t quite hit the mark.
The most efficient model is the 118bhp 1.6-litre diesel that can achieve up to 91.1mpg on the combined cycle. This model is only available in mid-spec Active trim. In automatic form (proper 6-speed torque converter this time, not the old jerky automated-manual like other PSA products) it still hits an impressive 88.3mpg according to Peugeot, keeping CO2 levels down and as such running costs.

Higher up the range, numbers remain right on the class best, with even the 267bhp GTi still claiming an impressive 47.1mpg and 139g/km of CO2. Unlike older Peugeot models, keep the specification reasonable and residual values won’t hit too hard. Pay bigger money for high specification cars and expect to take a hit however, as they struggle to hold on to as much value as equivalently priced Audi A3s and VW Golfs.
