Tesla Roadster

Electric are known for being quiet. Too for some. When the subject up among gearheads there is a lot of griping and groaning about how can’t imagine trading in V8 for something as silent as a church

If the Tesla Roadster is any indication, needn’t worry.

Sure, a bizarre sight to have one fly by you at steam making no more than an oversized remote car, but from the driver’s it’s an entirely different

While there is no engine the thunder of thousands of tiny through a finely tuned every minute, there is a and a transmission and fans and pumps and and other assorted moving that deliver an aural straight out of the movie Tron.

A fitting sound I can t imagine.

the public ups and downs this (upstart, if you work in Detroit or for Big has gone through over the few years, one simple fact The Tesla Roadster is real. You can buy one and you can one. I recently did the latter.

In a fitting of a company headquarted in Valley, Tesla assembles the in Menlo Park, Calif. a chassis built by Lotus in an electric motor manufactured in and a battery pack it constructs in using parts imported Japan. Electric cars been around a long but it’s that last of the puzzle that brings into the 21st century.

Unlike the Mini-E concept uses a smaller, air-cooled ion (Li-ion) battery pack, the one in the is both liquid cooled and This allows it to extract than the typical 50 percent of you can usually squeeze out of Li-ion without destroying them. claims over 80 percent of the energy can be accessed in normal and you can even tap into that 20 percent if desired, but the added will hurt the battery in the run.

Comprised of a staggering individual cells, the Roadster’s 992 pack pumps out 53 kilowatt (kwh) of electricity. For comparison, the in everyday hybrids typically less than 2 kwh, is why you can only drive one of those a of miles in electric mode and the can go 244.

That is if you happen to like a tester for the Environmental Agency. Most people who buy sports cars are looking for an slightly more exhilarating that one probably is, and the Tesla delivers, up to a point.

Despite the of the batteries, the aluminum and composite of the rest of the car keeps the weight 2,700 pounds, about 500 than a Chevy Corvette or 911. With 276 pound-feet of on tap the second you touch the accelerator, the can sprint from 0-60 mph in a 3.9 seconds, a feat helped by a that has just a single and doesn t require any time shifts as you approach the speed

Sadly, even though promotional material is peppered the phrase 100% torque, of the time, the company’s own power show that it actually to drop off around 5,500 So by the time you are in ticket territory the fun is starting to dissipate.

That’s not to say go downhill quickly from At extra legal speeds the 248 Roadster merely goes being rail gun fast to old rocket sled fast up to its speed of 125 miles per hour, at point the motor is spinning at rpm.

But it won’t stay for very long. If you run the Roadster that for an extended period of the motor, which is air cooled, heat up and the Power Electronics (PEM) will dial the power to help cool it You can override this to a point by to a special performance mode, but be sacrificing some of the life of the in the process and ultimately the Master Program will have its way and your request before you kill it.

You ll also be giving up a lot of in the process. To get those 244 miles out of the you need to use the control screen to the PEM to its extended-range setting which the torque by about half, the performance more like a Miata than a missile. By no is it slow in this mode, but if a Challenger SRT8 pulls up to you, it s better to look the way.

When I picked up the for my drive, it was set to normal and fully-charged, the meter indicating that I had 150 miles of juice in the box. a day of putting it through a variety of including city traffic, cruising and mountain roads, I it about 140 miles before the low warnings started in earnest. By I was already in extended mode, not to look worried that I t going to make it back to the

In case, you won t be taking the Tesla too far from base unless you a place to plug it in and lie down for a of long naps on the other

Hopefully you live near terrific tarmac and that won t be an Compared to most cars, the is a nimble beast, with unassisted steering that the road like a seasoned reads a teleprompter. Unfortunately, big battery means that its is about as heavy as someone who s most of their life down, so the car s balance is short of

This only becomes an when you are being particularly and the firm, double-wishbone suspension and tires do their best to the Roadster s inherent shortcomings.

from the sounds the car makes, the notably odd thing about the experience is the regenerative braking Designed to send some of the power back into the it is a particularly aggressive setup you feel as soon as you take foot off of the accelerator. There s no off the power and just gliding. You are on it, or on the brakes, even if you don t hit the pedal.

Tesla has put 300 Roadsters on the road so far and deposits for 1,000 more. on where the owners live, re running around on electricity by everything from wind to power to coal, so the upstream benefits of owning one need to be if that s your reason for one.

If it s the cost of the energy you re with, then Tesla you ll be paying about 2 cents per though electrical prices widely. A Prius will you 4.5 cents per mile in gasoline, but a apt comparison would be a Corvette Z06 chugs 12 cents of premium the same distance, and that s gas sitting close to $2 a gallon.

For though, the biggest concern electric cars is the battery, and or not it will last as long as the of the car.

Tesla thinks so and it a 3 year/36,000 mile warranty, that it should make it to 5-7 years and 100,000 miles, performance will probably off some with age. If you do to replace it, the cost is just I say just, because replacing the wimpy battery in a Prius set you back $3,000, so Tesla s seems like a pretty deal given what you
