As one of the most desirable electric cars available today, the 2013 Tesla Model S is also one of the best luxury sedans, too. Tesla has tinkered with the Model S's standard features slightly as the model year has progressed, but in general expect standard equipment to include 19-inch wheels, xenon headlights, full power accessories, cruise control, dual-zone automatic climate control, a 17-inch touchscreen, a rearview camera, cloth/premium vinyl upholstery, heated eight-way power front seats (with four-way power lumbar), 60/40-split-folding rear seats, a power tilt-and-telescoping steering wheel, a rearview camera, Bluetooth phone and audio connectivity, and a seven-speaker sound system with dual USB ports (charging only) and HD radio. A cellular connection, Internet radio and WiFi connectivity are also included. Standard safety features for all 2013 Tesla Model S variants include head, knee and pelvic airbags for the front passengers as well as front and rear side curtain airbags.
