The Best Supercars of All Times

It starts with the battery. Tesla’s is the best in the business, with 50 percent higher energy density by weight than the next closest EV competitor’s (Nissan Leaf). Though really, the Model S doesn’t have competitors, at least not directly. Because the battery offers so much capacity, the Model S needn’t compromise its mission with a bulky gas-powered range extender. You’ve heard the rationale behind Tesla’s purity movement: Having a single propulsion element, the motor, allows for more battery cells, which extends electric range, obviating the need for a Plan B, the internal-combustion engine.
