Tesla Motors has been touting its impressive Roadster for
quite some time now. The $100,000 sports car boasts impressive specs including
a top speed of 130MPH and the ability to accelerate from 0 to 60MPH in just 4
seconds. At the time the Tesla Roadster was first announced, the vehicle was
projected to have a
range of 250 miles thanks to its 6,381 cell lithium-ion battery pack.
Tesla Motors, however, has just informed its customers who
have already put a down deposit on the vehicle that the driving
range will come up short. The company can no longer guarantee the 250 mile
range after extensive on-road testing. Instead, the EPA certified range of the
vehicle is expected to be "greater than 200 miles."
Darryl Siry, VP of Marketing for Tesla Motors, cites a
number of reasons for the decrease in driving range. Changes have been made to
improve the safety of the battery pack, lower capacity lithium-ion cell had to
be used to increase durability and added weight to the chassis to the tune of
several hundred pounds have also hindered performance.
"The original premise of this groundbreaking car was
that its range would be high enough that you would not have to worry about
charging during a typical day, even if you have a long commute, take the car
out for dinner and chores, or even take the scenic route home," said Siry.
"Once home, you plug it in - just like you would your cell phone - and by
the time you're ready for another day, your Tesla Roadster is fully charged and
ready to go. We believe that this premise is still intact with a range above
