Over the weekend BMW unveiled their i8 Spyder Concept. Today we have an additional video, showing the drop-top concept in action. 

For those not in the know, the i8 is BMW’s most advanced car yet. It features a 170-hp electric motor which powers the front wheels. Powering the rear wheels is a 1.5 liter, three cylinder engine which produces 223 horsepower and 295 lb.-ft. of torque.

With numbers like that, the i8 manages a 0-60 time in about 4.9 seconds, thanks to the cars relatively light weight. It’s also very quiet, something you can witness for yourself in the video.

With the car’s fuel-economic credentials, the i8 has an all electric range of 20 miles, before the three-cylinder range extender kicks in, which will apparently achieve something close to 78.5 mpg.

Check out the concept in action in the video below.
