N!NJA writes with the mention of a recent alternative energies rally where the Tesla Roadster managed to cover 241 miles on a single charge, with another 38 miles of juice still left in the battery. "That would give the Roadster a theoretical maximum touring range of nearly 280 miles — 36 miles more than Tesla itself reckons the car will cover on a charge. If the numbers stand up to official scrutiny, Tesla will hold the world record for the longest distance traveled by a production electric car on a single charge. Of course, it should be pointed out that the Tesla was driven by a company staffer doubtless practiced in eking out every last mile from a charge, and that the speeds averaged on the run were hardly blistering — 90kph (56mph) on the motorways, 60kph (37mph) on trunk roads and 30kph (19) in the mountain roads. Tesla reckon the average speed for the entire journey was 45kph (28mph)."
