HIGH-PERFORMANCE ENGINE

"Peugeot 308 R HYbrid is part of a very select club of cars reaching 0 to 100 km/h in less than four seconds,” Jean-Philippe Delaire, Peugeot Sport, Head of Development of the Peugeot 308 R Hybrid powertrain.

Peugeot Sport systematically called on its technical expertise and successful motor racing track-record to define the specifications of each component as well as its ideal position. The powertrain thus combines three sources of power, each powering the vehicle independently of the others:

- the 4-cylinder petrol 1.6L THP 270 S&S engine, with the highest special power rating in the world for this engine size
- an electric motor with power of 85 kW / 115 hp, linked to the 6-speed gearbox
- an electric motor with the same characteristics on the rear axle

For impeccable dynamic handling, the car’s weight has been re-centred and positioned as low as possible. The Lithium-Ion 3 kWh battery has an excellent ratio between power and size, and has been placed under the rear seats in place of the fuel tank. In turn, the 50L fuel tank has been placed in the boot above the rear electric motor and the two transformers. In their quest for perfection, the Peugeot Sport engineers have completely redesigned the bottom of the fuel tank so that it sits tightly up against the technical components. The few millimetres thus gained on the vehicle height contribute to its performance.

Thanks to the all-wheel drive system, the handling of Peugeot 308 R HYbrid is pretty formidable, especially coming out of the bends. The braking system is on a par with the car's performance with 380mm ventilated discs at the front, gripped by four pistons, and 290 mm discs to the rear. However, they are not used every time the brakes are applied, because Peugeot Sport has designed the powertrain to decelerate using the electric motors throughout the full speed range, starting at 250 km/h. Not only does this preserve the discs and pads, but this regenerative braking system is also one of the three ways of recharging the battery.
