&lt;p&gt; Tesla's Model S has been around only a few years, but it has already evolved more than most cars do in a decade. It started out rear-wheel-drive and quick. Now it's got dual motors, all-wheel drive, and a Lamborghini-hounding 2.8-second zero-to-60 time. And with autopilot, it'll pretty much drive itself. We didn't really mess with that, though, because this is a car you'll want to drive for yourself. With 762 horsepower, the P90D is the most powerful sedan you can buy. And the most powerful electric car. And the most powerful American car. &lt;/p&gt;
