BMW will showcase the BMW Concept X5 eDrive at the New York International Auto Show 2014, a concept it sees as the logical next step towards bringing a radical reduction in fuel consumption and emissions in the SUV segment.
The BMW Concept X5 eDrive integrates, as the name implies, a plug-in hybrid drive system. A conventional combustion engine works with the BMW eDrive technology to produce the brand’s hallmark sporty drive coupled with a significant reduction in fuel consumption, said BMW. As a result, the car is able to drive on electric power alone at speeds of up to 120 kph (75 mph) and for a distance of up to 30 kilometers (approx. 20 miles), while recording average fuel consumption figures of less than 3.8 l/100 kilometers (more than 74.3 mpg imp) in the EU test cycle.
BMW explained the concept study underwent a series of detailed refinements in preparation for its appearance at the New York International Auto Show and is equipped with a drive system comprising a 180 kilowatt (245 horsepower) four-cylinder gasoline engine with BMW TwinPower Turbo technology and a 70 kilowatt (95 horsepower) electric motor, also developed by the BMW Group.
The motor is supplied with power from a lithium-ion battery that can be charged from any domestic plug. To ensure a particularly high level of crash safety, the high-voltage battery developed for the BMW Concept X5 eDrive is housed underneath the luggage compartment, whose everyday usability remains virtually uncompromised, said BMW, thanks to the 40:20:40 split-folding rear backrest and an almost level loading floor.
Per the Bavarian company, in addition to the settings that can be activated using the characteristic BMW Driving Experience Control switch, three driving modes can be selected according to requirements and the situation at hand: intelligent hybrid drive with an optimal relationship between sportiness and efficiency (AUTO eDrive), pure electric and thus local emission-free driving (MAX eDrive) and SAVE Battery to maintain the current charge level.
Electrification of the powertrain is a key component of BMW EfficientDynamics technology, declared the company, and allows BMW to unlock potential for reducing fuel consumption and emissions. The BMW eDrive technology developed for this purpose comes in various versions, each precisely tailored to the particular vehicle concept. Both the BMW i3, the first all-electric production vehicle from the BMW Group, and the soon-to-be-launched BMW i8 plug-in hybrid sports car are powered by BMW eDrive technology.
BMW stated the Concept X5 eDrive now follows in the tire tracks of the BMW Concept Active Tourer unveiled in 2012 by demonstrating how model-specific BMW eDrive technology can be employed in plug-in hybrid models from the BMW core brand.
This concept is the first time that BMW eDrive technology has been hooked up with the BMW xDrive intelligent all-wheel-drive system.
Regardless of the selected driving mode, the drive power generated by the electric motor, the combustion engine or the two units acting in unison is channeled to wherever it can be converted into forward propulsion most effectively. BMW added this allows the concept study to deliver all the qualities that SUVs are renowned for – superb traction and optimized handling stability in all weather and road conditions coupled with enhanced agility when taking corners at speed – in remarkably efficient fashion.
The BMW Concept X5 eDrive is able to complete the standard sprint from rest to 100 km/h (62 mph) in under 7.0 seconds, according to BMW.
The BMW Concept X5 eDrive is designed as a plug-in hybrid, allowing its high-voltage battery’s energy levels to be renewed from any domestic power socket, a special Wallbox that can handle higher currents, or at a public high-speed charging station.
BMW said the Wallbox Pro is designed for installation in the customer’s garage and offers complete ease of use as well as exceptionally short battery recharging times, thanks to a maximum charging rate of 7.4 kilowatts per hour. It is controlled by means of a high-resolution touchscreen including proximity sensor, while LED light strips provide an additional indication of the charge status. The built-in load management facility governs the charging current in accordance with the current draw on the household electricity supply. The Wallbox Pro even makes it possible to use home-generated electricity, such as that obtained from solar panels.
