12. Tesla Model S
Complex Says: Until now Tesla has just produced the Roadster, an electric sportscar that wasn't as fast as anything else in its price point and was weighed down by a massive battery. The new Model S is going to be a practical four-door that seats seven and will make or break the company. If it can move enough copies of the Model S, Tesla could be around for a while. But if there's another poor sales year or two, we think the whole thing will implode.
