TESTING the Tesla Roadster. “I’m on a three-day, 460-mile mission to challenge the Tesla hype and decide if living on 375 volts is actually enjoyable in the gas age. First order of business: I never got close to Tesla’s claimed 244-mile range in which the car can drive without a recharge. Had I driven like a maniacal hypermiler and avoided highways, which drain the battery much faster than back roads, I might have hit 200 miles.”
