Tesla Roadster
There have been several reports over the last few days talking about the Tesla Motors all-electric Roadster. (see Autoblog.com) From its unveiling in California with Governor Schwarzenegger present at the Santa Monica airport hanger to the youtube video included below, this is an impressive electric vehicle. According to Tesla chairman Elon Musk, the $80-$100,000 hand-built car is capable of a 250 mile range and has all the creature comforts of other vehicles. The silent power is not only ‘clean,’ but can deliver outstanding performance. (130mph and 0-60 in 4 seconds) If the design looks somewhat similar to what is produced by Lotus, it may be no surprise then that this vehicle may be built at Lotus in the UK. (Hethel) This is one EV that I’d like to see in my garage!
