BMW will present the Concept X5 eDrive all-wheel drive plug-in hybrid at the 2013 Frankfurt International Motor Show (IAA). The Concept X5 eDrive delivers the handling of a BMW, with an all-electric maximum speed of up to 120 km/h (75 mph), maximum electric range of 30 kilometers (19 miles), and average fuel consumption in the EU test cycle of 3.8 liters per 100 kilometers (61.9 mpgUS).
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. (Earlier post.) The 70 kW/95 hp motor sources its energy from a high-voltage lithium-ion battery that can be charged from any domestic power socket.
As part of the boost function, the motor can also be used to give the combustion engine a noticeable hit of extra energy during acceleration and during dynamic mid-range sprints. The BMW Concept X5 eDrive can accelerate from 0 to 100 km/h (62 mph) in less than 7.0 seconds.
The high-voltage battery developed for the BMW Concept X5 eDrive is mounted in a particularly crash-safe position underneath the load area, the capacity of which remains virtually unchanged as a result.
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; or Safe Battery mode to maintain the current battery charge.
Like members of the current series-produced BMW line-up, the BMW Concept X5 eDrive also offers ECO PRO mode, which is activated using the Driving Experience Control switch and 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.
Drivers can also use the hybrid-specific Proactive Driving Assistant, which teams up with the navigation system to incorporate factors such as route profile, speed restrictions and the traffic situation into the driving mode selection.
Drivers can also switch to the all-electric driving mode. Another option is the Safe Battery mode, which 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.
Functions from BMW ConnectedDrive help drivers to maximize the number of journeys they complete on electric power alone. For example, in the BMW Concept X5 eDrive, the electric range available is shown as a numerical value. The car’s dynamic range display uses intelligent connectivity to monitor the factors affecting range, such as traffic conditions, route profile and driving style.
When the route guidance function is activated, the location of public charging stations is added to the points of interest shown 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 once again.
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.
