Top speeds are more relevant than many people think.

That even applies to cars like the Tesla Model S, though perhaps more for bragging rights than any practical purpose. And as bragging rights go, 133 mph isn't too bad for an electric car.

While there aren't many places you can legally explore a modern car's top speed, those three-figure numbers are usually a good indication of how well your car will cruise at freeway speeds.

A car designed to travel two or three times the speed limit will generally be relaxed, quiet and economical at the limit itself.

The Tesla Model S Performance is relaxed and quiet at pretty much any speed.

In fact, as you'll see (and hear) in the video above (via our sister site Motor Authority), wind and road noise are only really audible on camera at 90-100 mph, more than most people will regularly cruise at.

Acceleration only starts to tail off as the car breaks into the 120s, and it's all done at 133 mph. We make no guesses as to what the range might be at that sort of speed, even with the 85 kW battery pack--not that the Model S's gasoline-powered rivals will be particularly economical at 133 mph and above...

What'll be most remarkable to anyone unfamiliar with the Model S is just how quickly it reaches its top speed. Motor Authority measures it at 12 seconds to 100 mph (it could be less, as the driver appears to pull away fairly gently at first) and 26 seconds to 133 mph.

We don't condone exploring your car's top speed on the roads, of course, but it's nice knowing the Model S has plenty in reserve when you're at a steady highway cruise.
