Peugeot has taken a new approach to the hybrid technology with their 3008 HYbrid4 model. Unlike most of the hybrid vehicles which are petrol-engined, the 3008 HYbrid4 combines electric motor with a diesel engine. Well actually the diesel engine and the electric motor are not combined, as the HDi diesel sits at the front of the car, while the electric motor is located at the back. There are now mechanical links between the front and the rear drivetrains. Everything is controlled electronically between these two drivetrains.
Fitting the electric motor and its ancillary equipment to the rear of the vehicle provides a number of advantages and a completely new feature for the 3008, a four-wheel drive. While the HDi diesel engine drives the front wheels, the electric motor drives the rear wheels. Sounds a bit weird, but it actually works quite well in slippery winter conditions providing extra traction at slow driving speeds. The electric motor at the rear axle also improves weight distribution of the vehicle. This new structure also avoids the need for any major redesign of the vehicle’s engine compartment and therefore makes it easier to combine the hybrid system with different engine options.
The 2.0-litre HDi diesel provides 163 horsepower and 300 Newton metres of torque, while the electric motor delivers another 37 hp and 200 Nm. When the best acceleration is required the system can deliver maximum combined power output of 200 horsepower. The 3008 HYbrid4 can accelerate from zero to 100 km/h in 9,2 seconds and the top speed is 191 km/h. Depending on the driving situation and the selected driving mode, the HYbrid4 can be a front-wheel drive, rear-wheel drive or a four-wheel drive.
Driver can choose between four operating modes; Auto, Sport, ZEV and 4WD. The preferred driving mode can be chosen via a control selector mounted on the centre console. Auto mode can be used in all driving situations. The hybrid system controls the diesel engine and the electric motor to offer performance and small fuel consumption. The Sport mode improves performance and lets the diesel engine to rev a bit more. Sport mode also provides a bit quicker gear changes. ZEV mode maximises the use of the electric motor, if the batteries have sufficient charge. The HDi engine is used only when a quicker acceleration is needed. When just the electric motor is being used, the car is a rear-wheel drive. If the constant four-wheel drive is needed at slow driving speeds, it can be activated by choosing the 4WD mode.
With the diesel engine, the Peugeot 3008 HYbrid4 isn’t the sportiest hybrid vehicle, but it is enjoyable to drive thanks to the surprisingly good handling. The only thing that is not up to its level is the gearbox. The Hybrid4 is only available with the BMP6 transmission, which is an electronically-controlled six-speed manual gearbox. So it is a manual gearbox that works like an automatic. Sounds like a nice combination. No clutch pedal and you can change gears via pedals behind the steering wheel or let automatic do all the work. Unfortunately, its not that great, because the gear changing process takes a really long time. You can clearly feel how the acceleration stop shortly, before the next gear comes in. In a slow acceleration this isn’t as big problem, but if you want to gather more speed quickly, the short pauses in the acceleration are really annoying. This electronically-controlled manual should be more economical, but I would rather have a real manual or a real automatic, not a combination.
