The 1.2 e-THP Puretech 130 engine weighs 25kg less than the old 1.6-litre VTi petrol it replaces – and it has an even bigger advantage over Peugeot’s diesel motors, you’d wager.
It also benefits from 30 per cent less internal friction than the VTi. In 128bhp tune it beats Ford’s 1.0-litre Ecoboost triple on both power and torque, as well as even BMW’s 1.5-litre Mini Cooper three-pot on pulling power.
Put that kind of engine into almost any compact car and you’ll improve it. In the 308, you pretty well vindicate Peugeot’s whole dynamic philosophy.
Suddenly that tiddly steering wheel makes better sense, because cornering balance is improved and rate of roll notably reduced. In a heavier-engined 308 it’s all too easy to overwork the front contact patches at speed, flick the car into steady-state understeer, trigger the ESP and make the car’s cornering line unnecessarily untidy.
In this one, both steering response and outright lateral grip are higher – although steering feedback is still disappointingly lacking, making it hard to know exactly when you’re about to add that little bit too much lock.
Peugeot’s new six-speed automatic transmission is a multitalented unit, smooth shifting and intelligent in its timing in ‘D’, and fairly responsive and obedient in manual mode.
Hit the sport button and shift times sharpen slightly, while Peugeot augments the otherwise quiet motor with some artificial aural boost. I could have happily lived without the latter, but it’s not intrusive.
Meantime, the gearbox doesn’t struggle to downshift at high revs, lock up at lower crank speed, or generally do what you ask of it. It really only serves to make a great engine seem even better.
