2018 Tesla Model S 100D

Without the P (for Performance) tacked on to its badge, the Model S 100D puts emphasis on going farther between recharges rather than on drag-strip launches. The 100 in the name denotes the biggest battery pack that Tesla offers, a 100.0-kWh unit that resides under the floor of the car, while the D signifies the dual electric motors—one in the front and one in the rear—that supply a total of 483 horsepower. Without the P100D’s extra grunt or those electron-sapping Ludicrous or launch-control acceleration modes, the 100D boasts the longest EPA-estimated range of any current Tesla—and of any electric car—with its 335-mile rating. (The P100D nips at its heels with a 315-mile range estimate.)
