Badged the 308 R HYbrid, it has been developed by Peugeot Sport, the brand’s famous in-house engineering and racing division, with a combined 500bhp and four-wheel drive.

Peugeot_308R_HYbrid_1With front and rear tracks widened by 80 mm and riding on 235/35 R19 tyres, the 308 R HYbrid has been created to devour the road. Its front end styling is dynamic and imposing, the grille features a chequered pattern which allows air to cool the innovative 500 hp powertrain.

Peugeot_308R_HYbrid_2At the rear, it is remarkably understated, with a narrow spoiler at the top of the tailgate reinforcing the aerodynamics. The bumper’s twin air scoops help keep the battery temperature down by drawing out the hot air, whilst the lower section is embellished with a touch of white emphasising the car’s dynamic character.

The compact steering wheel and paddles fall immediately to hand, giving the driver finger-tip control over the six-speed gearbox. A head-up display provides all relevant driving information without the need to take your eyes off the road. Finally, the two buttons on the central console allow the driver to keep a check on the mechanics; the first activates the powerful powertrain, whilst the second gives access to four driving modes.

Peugeot_308R_HYbrid_3ZEV mode makes priority use of the rear electric motor. The front electric motor comes into play, depending on the pressure applied on the accelerator pedal. Road mode is specially designed for road use with power of 300 hp and torque of 400 Nm. The petrol engine delivers its full potential, while the rear electric motor helps during accelerations. The front electric motor is not used in this mode. Track mode delivers 400 hp and 530 Nm, mainly from the petrol engine and the rear electric motor. The front electric motor serves as an additional booster when accelerating. At the top, the Hot Lap mode is the most powerful, harnessing the full potential from the three power sources to reach a total of 500 hp and maximum torque of 730 Nm.

Peugeot_308R_HYbrid_8At the heart of the Peugeot 308 R HYbrid is an astounding technical innovation – a plug-in powertrain with four-wheel drive that develops 500 hp. The unit combines three sources of power, each capable of moving the vehicle independently of the others. They are a four-cylinder 1.6-litre THP 270 S&S petrol engine, plus two electric motors – each with power of 85 kW/115 hp – mounted one on each axle. The front one is linked to the six-speed gearbox.

The result is a family hatchback which is capable of supercar performance. The 308 R HYbrid can hit 62 mph from a standing start in only 4.0 seconds, with top speed electronically limited to 155 mph. In spite of such astonishing performance, CO2 emissions are just 70 g/km.

The car’s weight has been optimised and placed as low as possible. The lithium-ion 3 kWh battery has an excellent ratio between power and size, and is housed under the rear seats in place of the fuel tank. In turn, the 50-litre tank has been placed in the boot above the rear electric motor and two transformers.

The braking system is on a par with the car’s performance, with 380 mm 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 155 mph. Not only does this preserve the discs and pads, but uses regenerative braking to recharge the battery. It is one of three recharging strategies. The second uses the front electric motor as a generator, driven by the petrol engine, while the third solution is a rapid recharging terminal restoring the battery to its maximum power in just 45 minutes.
