BMW Concept X5 eDrive: 74.3mpgAugust 23, 2013
The BMW Concept X5 eDrive can return 74.3 mpg, emit less than 90g/km CO2, and drive for 19 miles, and at speeds of up to 75 mph, on electric power alone thanks to its plug-in hybrid drive concept.
The concept study’s BMW eDrive system consists of a four-cylinder combustion engine with BMW TwinPower Turbo technology and an electric motor which is also the work of the BMW Group.
The 70 kW/95 hp motor sources its energy from a high-voltage lithium-ion battery. It can be charged from any domestic power socket and has sufficient capacity to enable the car to travel up to 19 miles solely on electric power, generating zero local emissions in the process.
The high-voltage battery developed for the BMW Concept X5 eDrive is mounted in a particularly crash-safe position underneath the load area, whose capacity remains virtually unchanged as a result.
There is a choice of three driving modes – the intelligent hybrid drive option for an optimum balance between sportiness and efficiency; pure electric and therefore emission-free driving; or Safe Battery mode to maintain the current battery charge.
BMW eDrive technology is combined with the intelligent all-wheel-drive system BMW xDrive for the first time in the BMW Concept X5 eDrive, which features electronically controlled and fully variable distribution of drive between its front and rear wheels.
In all-electric driving mode, with the battery fully charged, the car can cover up to 19 miles on electric power alone and therefore with zero local emissions.
Safe Battery mode allows the battery’s energy capacity to be maintained, for example, if the driver wants to cover the final stretch of a longer journey through town on purely electric power.
As a plug-in hybrid vehicle, the BMW Concept X5 eDrive’s high-voltage battery can be recharged from any domestic power socket, a Wallbox designed to offer stronger currents or a public charging station. The battery unit means the car’s overall load-carrying capacity is only slightly reduced.
The route guidance function shows the location of public charging stations on the navigation map. Drivers can call up stations located along their route or at their destination, and the system also tells them how much charging time is required to fully top up the battery.
All information concerning battery charge and electric range can also be viewed on the driver’s Smartphone. A Remote app from BMW ConnectedDrive developed specially to meet the requirements of electric mobility enables owners to control the charging process from their phone. It also allows the vehicle to be pre-programmed while it is connected to an electricity source. For example, the heating and climate control system can be activated remotely to ensure a pleasant temperature inside the car before the driver sets off.
