The Peugeot 3008 HYbrid4 was the first diesel-electric hybrid to be offered on sale in the UK.
The hybrid system, which couples a 163bhp diesel engine with a 37bhp electric motor, remains unchanged.
However, tweaks to the engine management software have improved the efficiency of the way that the 3008’s batteries are used.
This means that the 3008 HYbrid4 now returns average fuel economy of 80.7mpg and emits 91g/km of CO2, when fitted with 16-inch low rolling resistance tyres – improving on the current model’s 74.4mpg and 99g/km.
When larger wheel and tyre combinations are specced, the 3008 now emits 99g/km (down from 104g/km), making all models of the Peugeot 3008 HYbrid4 range free to tax.
