New for 2013, the Tesla Model S is a RWD, full-size, electric fastback sports sedan powered by an AC permanent-magnet synchronous electric motor with only one moving part (the rotor). The standard Model S produces 362 hp and 325 lb-ft of torque, for a 0-60 time of 5.4 seconds. Upgrade to the sport-tuned Model S and performance jumps to 416 hp and 443 lb-ft of torque, for a 0-60 time of 4.2 seconds. Both models use a single speed transmission and are rated as zero emission vehicles. Owners have the option of charging their vehicle using a standard 120-volt wall outlet or 240-volt outlet that, when charged using a Tesla Supercharger, can bring about 50% battery life in just 30 minutes. A full charge has a range of 208 - 265 miles, depending on the battery (60 kWh vs. 85 kWh). Features include driver seat detection for start/stop functionality, backup camera, dual zone automatic climate control, navigation system, internet browser, 5+2 seating, advanced multi-media system, and hands-free phone capabilities. Safety is comprised of eight airbags and advanced positioning/crash sensors. The Tesla S is backed by a 4-year/50,000-mile warranty (8-year/125,000-mile warranty for the battery).
