Have you seen BMW's new turbodiesel hybrid electric concept car? It's called the "Vision EfficientDynamics Concept" and it focuses on cranking out performance from a three-cylinder turbodiesel engine coupled with a pair of electric motors cranking out 265 horsepower and 590 lb-ft of torque.
From a developmental standpoint, the vehicle's aim is to marry the performance of a BMW M Car, the looks of a supercar and the fuel economy and emission management of a small premium car.
In other words, all of the vroom-vroom of a gasoline-powered engine with none of the inefficiency.
The tech behind the effort includes:
- All-wheel drive layout with an electric motor on both the front and rear axle.
- Acceleration from a standstill to 100 km/h (roughly comparable to 0-60mph in the U.S.) in 4.8 seconds
- Top speed 250 km/h (155 mph), electronically limited
- Fuel consumption in the EU test cycle was 3.76 litres/100 km (equal to 75.1mpg)
- CO2 emissions 99 grams/kilometer.
- If you're into aerodynamics, the drag coefficient is an F1-friendly 0.22.
- Electric power is generated without the slightest increase in fuel consumption through efficient Brake Energy Regeneration. Energy is stored in 98 lithium polymer cells.
The concept car is a 2+2-seater with gullwing doors. Roof and door inserts are made of polycarbonate glass that automatically become darker as a function of incoming light.
As a plug-in hybrid, BMW says the Vision EfficientDynamics concept is able to cover the entire fuel consumption drive cycle under electric power alone.
Still, the vehicle is able to cover a distance of just 31 miles in the electric mode alone.
Here's a video about the design behind the project:

BMW is again showing its commitment to environment with this super-electric/hybrid car if i can call it like this....go go BMW
The only fair comparison when it comes to "fuel economy" is to state what the gas mileage is if the batteries are EMPTY and the fuel tank is FULL when the test cycle is started! Otherwise no one has accounted for the energy used to charge the batteries. THAT can not be considered part of "fuel economy."
Something went wrong with your KiloMeter per Liter conversion into Miles per Gallon, I think. 100 Kilometer on 3.76 Liters is 26.595 Kilometers per Liter. According to my calculations, this is equivalent to 62.556 Miles per Gallon.
A BMW is a driving experience that I love. Will it also be a sustainable one? Does it have to cost an arm and a leg to be both? Will there be a tamer version that gets BETTER mileage and produce less greenhouse gases? Most importantly, WHEN?
