The standard motor is a 270-kilowatt (362-hp) unit that powers the rear wheels. Remember, though, that like all electric cars, real-world range will vary considerably with speed, acceleration, driving style, temperature, and other factors. The EPA rates the largest battery at 265 miles of range ratings aren't yet out for the other two. All packs are thermally conditioned with liquid cooling or heating, for better energy retention and more predictable performance. The medium-size pack was set to start deliveries very early in 2013, with the smallest battery following a few months later. Three battery-pack capacities are offered-85 kilowatt-hours, 60 kWh, or 40 kWh-with production focusing first on the largest packs. The floor-mounted lithium-ion battery pack of the Model S gives it a very low center of gravity, and the rear-mounted electric drive motor frees up the compartment up front under the hood-which contains a storage compartment that Tesla insists on calling the "frunk," or front trunk. We're more than a little curious about the safety provisions, though-those kids sit very close to the liftgate. Still, short of large crossover utility vehicles, no other sedan even tries to hold seven occupants. They're only suitable for kids willing to wear the four-point safety harness, but they let Tesla claim that the Model S holds seven passengers. While the Model S competes in the sport-sedan segment, it's actually a five-door hatchback with a pair of optional child-sized jump seats facing rearward in the cargo bay. While we wonder about the distraction that comes from relegating all the minor controls to the center display, it has large icons and clear, easy-to-read fonts, so it's more usable than any we've seen.
TESLA MODEL S ICONSOLE DRIVER
There's also a smaller instrument display for the driver in the usual position behind the steering wheel.

Its sheer size, graphic design, bright display, and lightning-quick response really make any other car's touchscreen interface feel 10 years old. The interior is well made, but fairly simple, dominated by the stunning 17-inch touchscreen display mounted vertically in the center of the dashboard. The long, sleek shape of the 2013 Model S seems to remind onlookers most of the Jaguar XJ and XF sedans-good company to keep if you're a startup luxury carmaker.

It went into production in June 2012, and by late 2012, the company was building a few hundred each week, to work down its backlog of more than 10,000 orders for the all-electric luxury sport sedan. The 2013 Tesla Model S is the second year for the first high-volume car from Silicon Valley startup Tesla Motors.
