Lately, we've seen the Tesla Model S make a fool out of quite a few supercars, such as the new BMW, M5, the Dodge Viper SRT10 and the Aston Martin Rapide S. We can't help but wonder just how much power is there under the hood of the Model S? Tesla's official specifications say only that it has an 85 kWh battery and an electric motor. They also mention that the Model S needs just 3.9 seconds to get from zero to 62 mph (100 km/h) and that it can reach a top speed of 130 mph. Recently, the British journalists put the Tesla Model S to the test on the Dyno, and here are their results. The Tesla Model S they tested has a horsepower output of 428.2 hp, which was measured at the wheel. Usually, carmakers measure the power output of their vehicles at the crank, which is a lot higher than the one measured at the wheel. This means that Tesla could advertise a higher number for the Model S.
In any case, if you're looking to challenge a Model S between stop lights, you should know that it develops around 430 hp.
