Tesla Model S continues to blow minds with its capabilities, this time on a dyno machine. Dragtimes crew are the first to strap a Model S to the Dyno, and they arrived at 388 horsepower at the rear wheels. Turns out the drivetrain loss for electric vehicles is not as substantial as normal cars. Tesla’s official number for this powertrain is 416 horsepower.

Part of the reason for that is due to the nature of an electric drivetrain. In the Model S you have the battery pack located under the floor in a steel case which forms part of a chassis, and a motor located between between the rear wheels. And of course electric car don’t have a transmission as such. So there is little waste.

It is hugely impressive what Tesla has accomplished with a bunch of laptop batteries and and an electric motor basically identical to that of a milk float. That 386whp gives the Model S a 0 to 60 mph sprint time of 4.4 seconds – which is the same as a BMW M5 F10.
