Tesla: the American-made, 100% electric sports car



Tesla sells a 40-amp universal mobile connector (about six hours for a recharge) for $1,500. A 70-amp home connector, which will top off the battery from empty in less than 4 hours, goes for $1,950.

“As many as 20 percent of our owners actually have installed solar recharging systems,” Mr. Snyder said. “One owner has even come up with a calculation of the Roadster’s fuel economy on sunshine.”

The Roadster’s range on a full charge is 244 miles in the E.P.A.’s combined city-highway test, which precludes it from being a long-haul vacation car. I inquired about driving it the 280 or so miles from Los Angeles to Las Vegas….

All Roadsters use an air-cooled A.C. induction motor rated at 215 kilowatts — the equivalent of 288 horsepower — but the Sport gets a boost to 295 pound-feet of torque over the regular Roadster’s 273 pound-feet, making acceleration stronger from 20 m.p.h. to 50 m.p.h.

The automatic transmission has a single speed. Tesla says that accelerating to 60 m.p.h. in this 2,723-pound dart takes less than 3.7 seconds; the top speed is electronically limited to 125 m.p.h….

Brembo brakes will effectively stop the car, but the immediate regenerative braking when taking your foot off the accelerator is more than enough to whoa it down (to about 3 m.p.h.). The car can be driven at least 90 percent of the time with just your right foot….

Give Tesla Motors its due; despite many setbacks along the way, it ultimately delivered the Roadster — though the car ended up over budget and far behind schedule, and many executives left the company under unhappy circumstances.

Still, the Tesla Roadster works pretty much as promised. And, as such, it is worthy of a measure of acclaim as an automotive pioneer.


* Next up, the Tesla Model-S, which aims to have a 300-mile range and a 45-minute recharge time (perfect for a lunch break on any road trip).
