What is it?
The Peugeot 308 R Hybrid could be the next watershed moment for plug-in hybrid powertrain technology, which is flooding into the performance car market in the way that all advanced technologies tend to: from the top downwards.
It has transformed the modern hypercar into something we wouldn’t have recognised 20 years ago, and has left a big impression on the sports car scene in the outlandish shape on the BMW i8.
While the decidedly lukewarm Volkswagen Golf GTE has already given it an outing of sorts among hot hatchbacks, that debut is nothing like what rival European car-maker Peugeot is currently planning: a five-hundred horsepower four-wheel-drive mega-hatch capable of accelerative potency and responsiveness unmatched within its class.
Though the R Hybrid draws primary motive power from Peugeot Sport’s 266bhp 1.6-litre turbo four as seen in the 308 GTi and RCZ-R, it also carries 200kg of not-entirely-useless ballast accounted for by a 113bhp, 148lb ft electric motor for each axle and a 3kWh lithium-ion battery where the fuel tank would otherwise be.
Unlike in other performance hybrids, the 308’s front electric motor drives straight into the Torsen limited-slip front differential, bypassing Peugeot’s six-speed automated manual gearbox entirely. Both front and rear electric motors transfer their power via single-speed reduction gearing.
