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 Motor Trend 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.
Motor Trend 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.
Motor Trend figures the real world driving range is 238 miles in their testing, 11% short of the claims 265.

The elephant in the room

You've all missed the elephant in the room. It's the cost of replacing the battery. How much will one of these cars be worth after two or three years with the looming uncertainty of how much longer the extremely expensive battery will last? It will make the depreciation of even Italian cars look like nothing...

Battery life does not decrease that fast. After 10 years the batteries are covered under warrenty to be at 75% of their original capacity.

Also you will never replace the entire battery. The battery is made of cells. In tesla's case, thousands of cells. If a cell goes bad, that one cell can be replaced at a low price. Much better than having to replace the entire transmission ;)

So let's hope you don't have to replace the Tesla's transmission at the same time as the battery pack. BTW, who says the entire battery pack won't be swapped out. That's what they do now on hybrids when the rare failure occurs. And I don't see anyone charging only $6 to swap out a cell including Tesla.

Enjoy ignorance? Please skip this.

Simple answer: Hybrids used lead-acid batteries. Lithium batteries are a completely different archetecture. With Li batteries they have cells and the cells are what are replaced.

As for the transmission: There isn't one in the Tesla. All current EVs are one-speed

Educate yourself before you make a bigger fool of yourself ;)

Quit making assumptions because you ARE making an a$$hole of yourself. :)

1. The Tesla has a transmission. It's not called a transmission when you have more than one speed. It's called a transmission when it performs the functions of a transmision. Here's a pic of it.

Hmmm. Looks like a transmission to me! LOL!

2. LI, lead acid, whatever. Those cells in the Tesla are in a...wait for it...battery pack. A self contained enclosure for the simple minded (you). In hybrids and EV's, those battery packs are removed en masse (unless you're in the DIY EV group...they install the battery cells without an enclosure for the most part). How do you think those cells get air and water cooled?
