PARIS: With 500hp on tap, call it the ultimate 308. Peugeot has unveiled the four-wheel drive 308 R HYbrid, derived from a concept announced in 2013.
At the heart of the Peugeot 308 R HYbrid is an impressive technical innovation – a plug-in powertrain with four-wheel drive that develops 500hp. 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 85kW/115hp – 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 Peugeot 308 R HYbrid can hit 100kph from a standing start in only 4.0 seconds, with top speed electronically limited to 250kph. In spite of such astonishing performance, CO2 emissions are just 70g/km.
"Peugeot 308 R HYbrid is part of a very select club of cars reaching 0-62mph in four seconds” said Jean-Philippe Delaire, Peugeot Sport Head of Development, 308 R HYbrid powertrain.
Peugeot Sport is the brand’s in-house engineering and racing division, which was also responsible for the RCZ R.
The lithium-ion 3kWh battery 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 Peugeot Sport engineers have equipped the car with four driving modes:
> Hot Lap mode is the most powerful, harnessing the full potential from the three power sources to reach a total of 500hp and maximum torque of 730Nm.
> Track mode delivers 400hp and 530Nm, mainly from the petrol engine and the rear electric motor. The front electric motor serves as an additional booster when accelerating.
> Road mode is specially designed for road use with power of 300hp and torque of 400Nm. 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.
> ZEV makes priority use of the rear electric motor. The front electric motor comes into play, depending on the pressure applied on the accelerator pedal.
The braking system is on a par with the car's performance, with 380mm ventilated discs at the front, gripped by four pistons, and 290mm 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 250kph. 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.
The 308 combines contemporary style and sporting prowess with design cues from the Quartz concept, seen most recently at March’s Geneva Motor Show.
With front and rear tracks widened by 80mm 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, with expressive louvres on the bonnet and sharp edges combined with sleek surfaces in its bumper.
The grille features a chequered pattern which allows air to cool the innovative 500hp powertrain. The side scoops are home to the sequential LED indicators, while the central scoop sports the 308 R HYbrid signature.
The 308 R HYbrid comes with a dramatic paint finish. Cloaked in an intense blue and developed using fluorescent pigments and glass particles, this colour is a tribute to the hybrid powertrain and the shade historically reserved for French competition vehicles. On the rear doors, the blue is matched with a matte black, giving a new interpretation of the car’s clean lines.
At the rear, the 308 R HYbrid is 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.
Peugeot ‘i-Cockpit’ instrumentation is familiar yet different. Four individual sports seats, upholstered in fawn-coloured patinated leather, create a dramatic interior for world-class performance. The upper fittings and roof lining are slate grey, the cabin is finished with touches of red, with particular attention paid around the dials, steering wheel centre marker and central console.
In a unique twist, the 308 R HYbrid uses materials taken from the range, which the brand usually reserves for concept cars. Hence, the dashboard is covered in a fabric produced using a digital weaving technique. This innovative material can be used to produce large and complex parts that are soft to the touch with no need for foam, making for a lighter vehicle.
The compact steering wheel, upholstered in perforated leather and bearing the ‘308 R HYbrid’ logo, allows for precise positioning during cornering. The steering wheel 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 as described above.
