BMW released details of an updated version of their plug-in hybrid eDrive X5 SUV, which is set for debut at the upcoming New York Auto Show. They have changed the concept in ways that make it closer to a production model, enhancing its usability and efficiency.

The new BMW X5 eDrive is very economical for a car of this size and purpose, recording average fuel consumption figures of less than 3.8 l/100 kilometres (more than 74.3 mpg imp) in the EU test cycle, with CO2 emissions of 90 grams per kilometre. It even offers 30 kilometres (approx. 20 miles) of pure electric range, in which you can reach speeds of up to 120 km/h (75 mph).

The key to this astonishing performance is a hybrid system consisting of a 180 kW/245 hp four-cylinder petrol engine with BMW TwinPower Turbo technology and a 70 kW/95 hp electric motor. Thanks to the xDrive all-wheel-drive system the BMW X5 eDrive can also get out of its own way, with a 0 to 100 km/h (62 mph) time of under 7.0 seconds, and ability to deal with rough terrain just like a normal X5.

BMW engineers took care so none of the X5’s practicality and day to day usability has been lost in the hybrid version. The lithium-ion battery pack is located underneath the luggage compartment, you get a full-size boot.

Just about the only problem in the way of BMW X5 eDrive becoming a production model is the cost. The end result will end up being too expensive for it to make business sense. Most people would prefer buying a normal SUV and spend what they have saved on petrol. The eDrive is a technical masterpiece though, and something we will be hearing more about, especially in BMW “i” models.
