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.

And the problem with that is I get a swap out from company A that owns the battery, then my destination only has company B. Why would company B take their competitors batteries and charge them? If you think they can work out an agreement for charging one each others batteries, then why have separate companies in the first place?

What I am trying to say is that your swap out and lease system will only work if a single third party owns every single battery independent of the stations doing the swap outs and charging. Even then, there are only so many charged batteries that can be stored on site, so after a rush the station will eventually have no fully charged batteries. Then there is the fact that the battery packs are not one large removable unit all of the time. They can be distributed throughout the car to balance out weight problems.....

Basically, too many compromises. It will not work.

Do you guys have the gas cylinder swap thingo at gas stations over there? You buy a bbq with empty cylinder, go to a gas station and swap it for a full one. You can do it at just about any gas station in Australia.

We do, however the cost of a propane cylinder is trivial compared to the cost of a battery pack.
