Tesla Model S Hits 60 MPH in 3.9 Seconds, Misses EPA Range Estimates by 11%

All-electric Model S runs the 1/4 mile in 12.5-seconds at 110.9 mph
It’s doubtful that many people believe manufacturer estimates when it comes to fuel efficiency or driving range for electric vehicles. The driving range for electric vehicles obtained in government tests is often a far cry from real world numbers. On public roads, driving range for an electric vehicle depends on the terrain, how heavy the driver's right foot is, and even the temperature.
The guys over at
have laid hands on a
Tesla Model S
and set out to get a real world driving distance. The car used for the driving distance test is a Model S Signature Performance 85, and this particular vehicle happened to be Tesla CEO Elon Musk's personal ride. The test of the Model S also involved putting down some performance numbers, which enthusiasts will be interested to hear.
The big four-door Model S was able to hit 60 mph in 3.9 seconds. It also ran a virtually silent 12.5-second quarter mile pass at 110.9 mph. Those are impressive numbers for a gasoline-powered sedan, putting the Model S Signature Performance 85 in the same company as the BMW M5 and the Mercedes CLS 63 AMG among others.

The real question though is how far can the car drive. Being able to hit 60 as quick as an AMG badged Mercedes is impressive, but not so much if the battery pack is dead shortly thereafter. The largest battery pack available in the Model S is rated by the EPA at 265 miles in extended range mode.
After the performance testing was done, the car was completely recharged even though it is only consumed what the onboard computer said was 13 miles of range despite the quarter-mile passes and other performance tests. The real world driving distance test took place in California heading towards San Diego via Interstate 15 before hitting the I-5 and then the picturesque Pacific Coast Highway. The map showed the driving distance to be 240 miles.
says that the test was conducted with the air conditioner off, but ventilation on, cruise set at 65 mph, and the body lowered on its air suspension for driving distance. Apparently, the car was 1.7 miles short of making it the full 240 miles in real world traffic. Rather than run out of power the tester plugged the car and to get the extra few miles of driving range.
figures the real world driving range is 238 miles in their testing, 11% short of the claims 265.

Yeah, but recharging an 85kWh battery on a 6.6kW 30amp 240v circuit (common enough in homes, for electric washer/dryer/oven) from empty will take ~12 hours. You can get double 10kW chargers, but having a 20kW 240v circuit installed at your home is.. Expensive and rare..
Recharging that on a 1.5kW 120v circuit, like you would find on a road trip at hotels?
Me, the house I'm fixing to buy actually has a 40A circuit for the well pump (which is only on currently to water the lawn) and I'd want to get a 40A 240V charger with a switch between the two, so that it'd be connected to the charger most of the time. My Volt wouldn't be able to take full advantage of that with its 3.3kW charger, but perhaps the next (ER|)EV would.

No reason you cannot run or purchase a second connection and add a 100A or greater circuit for charging. It might cost a bit on an existing home to have an electrician install, but it would could be interesting if the gov could subsidise that cost with any purchase of an EV. On a new home you would hardly notice the difference.

Assuming parasitic loss is minimal, I would only have to charge this thing once every 6 days I commute with that mileage. However, I live in Chicago where it gets very hot and very, very cold, and that will definately reduce the range when you account for cooling/heating and weather conditions.
With Whole Foods announcing they are going to install at least two charging stations at every location by 2014 (and one being around the corner from where I live) I would probably pass having a charging station installed here since I don't even have a sheltered parking spot at my condo.
