Peugeot Sport is reportedly working on a new plug-in hybrid R performance model, and the lucky recipients are the 508 and 508 SW. Apparently, both R models will feature a more sophisticated PHEV system with all-wheel drive, as reported by Australian website motoring.

A senior executive from Peugeot told the publication that development of the R models is currently underway, and the uprated PHEV system is expected produce at least 350 hp. That of course refers to Group PSA’s electrification push, which will see all models get electrified from 2019.

The insider did not explicitly reveal the 508 R’s output, but it will be far more than the 300-hp AWD system in the 3008 GT Hybrid4. Expect the R to get the same 1.6 litre four-cylinder PureTech petrol engine and more powerful electric motors in place of the existing 80-kW units. That translates to a zero to 100 km/h time of around 4.5 seconds and a top speed of 250 km/h.

While the standard 508 Hybrid is strictly front-wheel drive, the Peugeot exec said there’s no reason why the twin-motor version (all-wheel drive) cannot be fitted to the 508. A larger and more energy-dense lithium-ion battery could also be fitted, up from the current 13.2 kWh battery pack (located under the floor of the rear passenger seat).

The 508 R will be based on the same EMP2 platform and is likely to get an independent multi-link rear suspension. Other features include an aluminium bonnet and front fenders, composite boot lid and 20-inch light alloy wheels. At launch, it will take on German rivals like the Audi S4 and Mercedes-AMG C 43.
