The 2017 Tesla Model S is a four- to seven-passenger luxury sedan available in seven variants: 60, 60D, 75, 75D, 90D, 100D and P100D. The digits refer to the kilowatt-hour (kWh) capacity of its battery (which directly impacts range) while the "D" denotes the dual-motor, all-wheel-drive models. The Model S 60 comes with 19-inch wheels, all-season tires, LED headlights, access to Tesla's Supercharger network, dual-zone automatic climate control, a 17-inch touchscreen, a navigation system, a rearview camera, keyless entry, parking sensors, power-folding and heated side mirrors, blind-spot warning, automatic emergency braking, lane departure warning, cloth and premium vinyl upholstery, heated power front seats, 60/40-split folding rear seats, a power tilt-and-telescoping steering column, Bluetooth connectivity, and a seven-speaker sound system with dual USB ports (media and charging) and HD radio. A cellular connection, internet radio and Wi-Fi connectivity are also included, as are a universal mobile connector for charging. The P100D uses the same battery pack and a second electric motor on the rear wheels.
