X Marks the spot for hybrid SUVs! BMW has already confirmed plans for a clever petrol-electric version of its new X6, which our spy snappers have just caught testing (above) with a huge bump in the bonnet. And now the firm has taken the wraps off this ultra-advanced X5. Set to be unveiled at next month’s Geneva Motor Show, the car looks like a standard version of the 4x4, but the Efficient Dynamics logo on the side signifies that it’s anything but. Underneath the standard body, there’s a hybrid powertrain, which enables the concept to match the ability of a conventional X5, despite only having a 2.0-litre diesel engine. The twin-turbo unit is supplemented by a 20bhp electric motor mounted to the car’s eight-speed automatic transmission. The result is a 0-62mph sprint time of 8.9 seconds, economy of 43.5mpg and CO2 emissions of 172g/km.With aerodynamic 19-inch alloys to reduce drag, these innovative technologies show what is in store for buyers after an eco-friendly SUV.
