26.3 kms/litre and 0 to 100 km/h in under 7 seconds in a large petrol-engined SUV like a BMW X5? Sounds good? It’s now possible using a hybrid drivetrain and BMW has developed a concept vehicle to demonstrate the capabilities.
Known as the Concept X5 eDrive, the hybrid SUV – sorry ‘SAV’, as BMW refers to its dual-purpose models – has almost all the features of the standard X5, including xDrive all-wheel drive, but replaces the petrol or diesel powertrain with a hybrid one.
According to BMW, a maximum range of 30 kms is possible on electric power alone. A boost function can be used to give the engine a surge of performance, enabling a 0 to 100 km/h in under 7 seconds.
The BMW eDrive system consists of a 4-cylinder petrol Twin Power Turbo engine and an electric motor. The 95-bhp motor gets electrical energy from a high-capacity lithium-ion battery which can be charged from a household power socket, besides regenerated energy from braking.
There is a choice of three driving modes, depending on requirements and situation – the intelligent hybrid drive option for an optimum balance between sportiness and efficiency; pure electric and therefore emission-free driving; or Save Battery mode to maintain the current battery charge.
An ECO PRO mode, activated using the Driving Experience Control switch encourages a particularly efficient driving style. This default mode is engaged when the car is started and offers intelligent hybrid functionality, whereby the energy management system tailors the interplay of combustion engine and electric drive system to most efficient effect.
Electrification of the powertrain allows BMW to ‘unlock’ impressive potential for reducing fuel consumption and emissions. The BMW eDrive technology comes in various forms, each tailored precisely to the vehicle concept at hand.
