Ex-McLaren Designer Unveils All Electric Roadster
The original idea for the new roadster was unveiled about a year ago, but at the time details were scant at best and until just recently, no new information was released. Now, Jim Dowel has given the world a look at the PE-1 and how he is planning on powering his new electric roadster.
The most advanced lithium ion batteries available will be used to store energy to power 2 electric motors, one at each axel of the vehicle. Together the motors will make an ample 390 horsepower and 590lb/ft of torque. Being all wheel drive should help to keep the tires attached to the pavement, but I can still foresee some traction issues.
From a standstill, the PE-1 should reach 60 mile per hour in about 2.9 seconds, thanks mostly to a curb weight of 2,325 lbs. Top speed will be limited to 130mph.
The decision to use an all wheel drive train was not based only on the power figures. A regenerative braking system was figured into the equation very early and by using all 4 wheels to recapture energy, the vehicle can go between 200 and 250 miles on a single charge.
A few prototypes will be built over the next year or 2, with an estimated 500 being produced by 2012.AutoBlog
