For an additional $2,000 you can have the "partial premium interior," which gets you power-adjustable, heated front seats, different upholstery, upgraded audio, LED fog lights (though those aren't inside the car, of course) and phone docking. This also upgrades you to the "standard range plus" car, priced at $37,000 before incentives, which has an estimated range of 240 miles.

The "premium interior," a $5,000 upgrade over the standard car, gets an internet browser, in-car music streaming, satellite-view maps with traffic information, heated front and rear seats and an even more powerful audio system. This environment is available on the $40,000, 264-mile "midrange" trim and the $43,000, 325-mile "long range" version.
