World's first diesel hybrid a Pug

The world’s first production diesel hybrid, Peugeot’s 3008HYBRID4. It has some all-wheel drive ability and improved agility thanks to a change from torsion beam to independent rear suspension. Nice.

Peugeot’s launched its 3008HYBRID4, the world’s first diesel-electric hybrid vehicle.

You may think it is just a standard 3008 with some batteries, yet this new hybrid has quite a lot of clever engineering contained within its odd proportions.

Motor by Bosch - batteries by Sanyo

The hybrid 3008’s electric drive component consists of a permanent synchronous magnet motor at the rear of the vehicle supplied by Bosch.

This electric drive unit provides constant outputs of 20kW and 100Nm, with short-burst peaks of 27kW and 200Nm available for surges of overtaking acceleration.

Paired with the 1.6l turbodiesel engine (worth 119kW and 300Nm) the 3008’s hybrid drive system tallies a very useable 147kW and 500Nm of combined peak engine performance.

The appeal of a hybrid drivetrain (beyond the combined burst acceleration performance) is, of course, lower fuel consumption and emissions.

To this end the hybrid 3008 dips under the 100g/km of CO2 threshold by a single unit (it emits 99g/km of CO2) and averages a trifling 3.8l/100km in the combined cycle.

Four driving modes control the variability of the 3008 hybrid’s diesel-electric blend.

In auto mode the system varies the diesel/electric split optimally to ensure as close to the claimed 3.8l/100km consumption figure as possible.

Zero Emission Vehicle (ZEV) mode runs on pure electric power (range unspecified) and is best suited for congested traffic driving. In ZEV mode the diesel engine is only activated when a burst of acceleration is required.

Thanks to its rear mounted electric motor the 3008 hybrid can operate as a pseudo-all-wheel drive vehicle too in 4WD mode. At best the 4WD mode is a traction aid for slippery driveways and snow-covered roads instead of challenging sandy tracks and shale strewn inclines.

Finally, sport mode sees the batteries run down as quickly as possible, proving most of the combined 147kW/500Nm combined peak performance.

The 3008 hybrid drives via a six-speed electrically controlled manual transmission with shift paddles located behind the steering wheel surrendering full control to the benefit more dynamically inclined drivers.

Flat rear floor, small luggage space penalty

Interestingly the front and rear drivetrains are not linked, due to the rear electric motor and its battery packaging being connected to the ECU with fly-by-wire technology. Without a centre-clutch pack (as is usually the case in all-wheel drive vehicles) the 3008 hybrid has a flat rear floor, which means it boasts true three person portability in the back.

The battery pack (slightly old-school nickel metal hydride batteries courtesy of Sanyo) only reduces the 3008’s luggage capacity by 15l compared to its pure internal combustion siblings.

Perhaps the best engineering change required by the 3008’s electrification has been the binning of its torsion beam rear suspension for a multi-arm independent wheel attachment set-up, sure to improve ride quality and agility.

Peugeot will release the 3008 hybrid to market in Europe during the first quarter of 2011.
