The BMW Vision EfficientDynamics X5 Concept will make its debut at the 2008 Geneva Motor Show on March 4 – 16 and this will mark BMW future approach toward low emission but high performance vehicles.
The Vision EfficientDynamics X5 Concept is powered by a 2.0-liter 4-cylinder diesel engine combined with BMW’s Variable Twin Turbo concept, third-generation common-rail injection and an all aluminum crankcase produces 204 hp and 400 Nm of torque between 2,000 and 2,250 rpm.
The engine also uses mild ActiveHybrid technology to deliver further 20 hp and 210 Nm of torque to the X5 Concept. The diesel engine is mated to a new 8-speed automatic transmission developed jointly between BMW and ZF where the gearbox delivers fast and efficient gear changes.
The concept uses highly efficient lithium-ion batteries in the boot area to store the power generated from the Brake Energy Regeneration and the roof mounted photovoltaic solar panels.
With the above technology, the BMW Vision EfficientDynamics X5 Concept delivers 43.5 mpg of fuel consumption on the combined cycle and just 172g/km of CO2 emissions. The Vision EfficientDynamics X5 also produces more than 100 hp per liter and it clocked 8.9 seconds from 0 to 62 mph.
The X5 Concept is also fitted with aerodynamically-efficient 19-inch light alloy wheels with reduced ventilation to reduce wind resistance.
