BMW Vision Efficient Dynamics Concept Car

The combination of these technologies provides overall system output of 262 kW/356 hp, with maximum torque at 800 Newton-metres/590 lb-ft. The car is an all-wheel drive consisting of an electric motor on both rear and front axles.
Projected performance is anticipated to be in the region of
zero to 100km/h in 4.8 seconds, with a top speed of 250 km/h (155 mph) - this is electronically limited. Fuel consumption in the EU test cycle measured at 3.76 litres/100km, with CO2 emissions 99 grams/kilometre.
Electric power is generated without compromising any fuel consumption efficiency, using a particularly efficient concept of Brake Energy Regeneration. The energy is stored in 98 lithium polymer cells, with a range of about 50 km using the electric mode alone. Well, this week we saw BMW release details of their latest sports concept car, but it's more than a sportscar.
BMW Vision EfficientDynamics is a combination of the potential of BMW ActiveHybrid technology, and the power of BMW EfficientDynamics.
Technology on BMW Vision EfficientDynamics concept car consists of a full-hybrid concept, and is powered by a three-cylinder turbodiesel and two electric motors.
The aerodynamics have been developed with input from Formula 1, and the result is a drag coefficient that has been optimised to just 0.22. The body has been designed with consistent lightweight technology as well as aerodynamic technology, with these qualities ensuring optimised sporting performance, as well as excellent efficiency.
On top of all this, the car features a 4 seater capacity which makes it not only a sports car but also well equipped for all round use.
Possibly, the cherry on top for some buyers will be the implementation of Gullwing doors, which open upwards. Even the doors have been designed to make entering and exiting the vehicle easy, making use of weight-optimised door kinematics.
And of course, moving onto the interior, the cabin has been designed using the very latest in modern technology. Last but not least, the roof and door inserts (made of polycarbonate glass) automatically become darker in light conditions, easing eye strain on both driver and occupents.
Having said all this, the car looks incredibly impressive, and BMW has once again shown why they are among the leaders of innovation, style, efficiency, class and performance. What more can we say?...It's a BMW.

BMW's future will be on display at the Frankfurt motor show, in the shape of the stunning Vision Efficient Dynamics concept car. As well as its striking looks, the car promises to blend supercar performance with supermini fuel consumption and CO2 emissions. Advanced technologyThe Vision Efficient Dynamics has an advanced diesel hybrid powertrain, which uses a mid-mounted, 1.5-litre turbodiesel engine with 161bhp and 214lb ft of pull. There are also two electric motors – one to power the front axle and one to power the rear. The rear motor normally produces 34bhp, but can provide a maximum of 51bhp, and is linked to a double-clutch gearbox.The electric motor at the front axle normally produces 80bhp, but can deliver 113bhp for up to 30 seconds and 140bhp for up to 10 seconds. Lithium polymer batteries are used to power the motors, with recharging achieved through brake energy regeneration and plug-in technology.BMW says that the Vision Efficient Dynamics will be capable of supercar-style performance, with 0-62mph in just 4.8 seconds and a top speed of more than 155mph.CO2 emissions of just 99g/km are also predicted, with an average fuel economy of 75.1mpg.The car will have a range of 400 miles using just the diesel engine and 31 miles in electric-only mode.Futuristic looks are F1-inspiredBMW says that the Vision Efficient Dynamics' futuristic looks have been influenced by the company's Formula One experience and are dictated by the car's lightweight construction and areodynamic efficiency. The sleek front end helps to channel the airflow over the car, with 'active louvres' in the radiators closing completely when the need for cooling is low. The underfloor of the car is fully covered from front to rear, to help it cut through the air as efficiently as possible. The 2+2 interior uses a number of high-tech, low-weight materials, including body-contoured seats with a Kevlar shell.
