High-end Tesla Model S could be the most efficient EV in the land

Tesla is set to put its Model S all-electric sedan on the market a few months ahead of schedule, with the first customer deliveries taking place next month. Another bit of good news for Tesla and the people who are waiting for their Model S to take up residence in their driveway has surfaced. 
 
Motor Trend reports that the top-of-the-line (85 kWh) Model S is expected to earn a window sticker rating from the EPA showing a 265-mile driving range.
 
There has been confusion on the driving range for a fully charged Model S, mostly because multiple numbers have been thrown around since the vehicle was first unveiled. The driving range has been at different times said to be 160-miles, 230-miles, and 300-miles depending upon the size of the battery pack installed. Tesla also recently noted that the car was able to achieve a 320-mile driving range on a full charge in the EPA's 2-cycle driving test.
 
The new 265-mile range for the window sticker is based on the EPA's new five-cycle test. If Tesla is able to land that 265-mile driving range on the EPA's new test, the Model S will be massively superior to other electric vehicles, such as the Nissan Leaf, which was only able to muster a 73-mile driving range on the same test. Granted, the high-end Model S is much more expensive than the Leaf.
 
The real world driving distance will likely vary significantly, depending on where the vehicle is operated and how heavy the driver's right foot is.
 
The Model S is also available with smaller 40 kWh or 60 kWh battery packs. The base Model S will sell for $57,400 and range up to $105,400 for higher end versions with an 85 kWh lithium-ion battery. Tesla has 10,000 orders in hand for the new Model S EV.
 
Word that the car may come early sent shares of Tesla stock surging.

Are you serious?
Pure Electric cars shit on anything combustion wise when it comes to acceleration,It's instant torque! lol
Go youtube White Zombie car blowing away a GT-R on the drag strip, Just a crappy old Datsun outfitted with electric motors and batteries shits on it's newer Datsun(Nissan hehe).
Think you may be referring to Hybrids which are pretty sluggish. The problem with electric cars is not the acceleration it is the range and the price,Both of which will continue to improve. Combustion engines have had how many decades to improve? Electric motors (for cars) has had bugger all time spent on them.

Have you driven one?

Electric motor acceleration is great off the line, but the torque drop off as you speed up is *not* great. Although the Tesla Roadster (Sport) is much faster in 0-60 than the Porsche Boxster (3.7s vs 4.3s), they have identical 60-80 (1.6s). There is no comparison at higher speed. The Boxster 80-100 time is about half of the Roadster time (3.3s vs 5.1s). See http://www.motortrend.com/roadtests/convertibles/1... for more info.

Really?

Even if engineers were able to make electric motors better, what improvement do you think is available? They are already 95% efficient! The battery is the problem/issue. Nothing else.

ICE cars won the early competition because they were more practical.

They still are.

So let's compare a 2012 Nissan Leaf to my 1991 Nissan 300ZX Twin Turbo:

Leaf 0-60: high 9's
300ZX 0-60: low 5's.

The first cars were electric. The electric motor is older and more mature than the internal combustion engine. Electric cars used to outclass gasoline-powered cars in almost every respect until the internal combustion engine was improved upon.

The sad fact is that the performance of electric cars has barely improved due to fundamental limitations in battery technology.

You can buy a 2012 Nissan Leaf with a 73 mile range today, but you could have bought a Fritchle Electric with a 100 mile range 104 years ago:
