Green Machines: Electric: Who Revived the Electric Car?
April 1, 2007
Nascent manufacturer Tesla Motors recently unveiled its all-electric Roadster to worldwide media acclaim (see Robb Report, October 2006). The audacious performer charges to 60 mph in around four seconds and continues to a top speed just north of 130 mph. Peak torque is available between zero-and-6,000 rpm and remains strong up to a 13,500 rpm redline. Because of this abundant torque, Tesla reports that both of the car’s two manual gears—selected without a clutch pedal—work equally well in most conditions. Technology, like regenerative braking, helps the Tesla achieve an impressive 250-mile range—though this will likely diminish if you spend all your time burying the accelerator pedal in the floor. According to the manufacturer, the Roadster returns the equivalent of 135 mpg. The car’s batteries should recharge in about three and a half hours and an optional mobile kit enables charging when the vehicle is away from home. The 2007 model run has already sold out—if you want a 2008 Roadster, get your order in now.
