Tesla Model S, Fully Electric Car Dyno Tested

When we think of dyno testing of vehicles, it is strictly for the race track, drag strip, performance minded companies, and a few muscle car enthusiasts, but when it comes to an electric car, that’s a different story.

The following information was gathered from our friends at TopSpeed.com.

Tesla has put out a fully electric performance model, the Tesla Model S. It has a larger capacity 85 kWh battery then previous models that supply the 416 HP (horse power) electric engine, which was rated by the factory.

The test results are in, and the final analysis through the drive-train was an impressive 388 HP. Meaning a loss of only a 28 HP, equaling out to a 6 percent reduction from the engine to the tires, very impressive. The minimal loss of HP is due to the direct drive system, having no transmission to steal the power on the way to the wheels, giving the performance end of the Model S a 0 to 60 mph time in 4.5 seconds and a top speed of 126 mph. A lot of gas powered performance vehicles can’t muster up that kind of results.

Electric engines typically have high torque, which will compensate for usually having a low HP in them. Not such is the case of the Tesla Model S, it gives you high torque along with electrifying, pardon the pun, HP delivering a constant peak torque of 600 to go along with the astounding 388 HP to the wheels.

A recent burnout was done by Road and Track which was not only impressive for an electric vehicle but it was also relatively quiet. Only the screech of the tires begging for mercy and a slight hum from the power-plant was heard. As the smoke was released from the tires, chucks of rubber flew in all directions. Sort of like the burnouts you see at the drag-strip.

Often you think of the roar of the engine drowning out the sound of the tires, but obviously an electric engine is fairly quite to begin with. So in the case of the Tesla Model S it’s a flip-flop, the sound of screeching tires drown out the noise of the engine.

Currently, the price for the Tesla Model S range from $57,400 to $77,400, deduct the federal tax credit of $7,500 for energy efficient vehicles and your cost will be $49,900 to $69,900. The cost to build this vehicle is at or above the selling price, so rumors that Tesla will have a price increase in the near future is spreading.

The actual price increase has of yet not been determined, but Tesla has released information that some equipment that use to be standard, will later become part of an option package. Meaning along with price hikes, there will be a decrease in standard features. However, this will not effect current customers who have placed orders on reservation, as long as the final order is placed within a predefined amount of time.
