First Drive: 2010 Tesla Roadster Sport improves on original, keeps quirks "To get from zero to 60 mph in the original Tesla Roadster takes an official 3.9 seconds. The brand new 2010 Roadster Sport beats that with a wonderful 3.7 seconds. Those two-tenths of a second don't look like much on paper, but they make a difference on the road. Perhaps just knowing about the enhanced acceleration makes the Roadster Sport feel faster in the absence of expensive testing equipment, because having driven both, it does feel that way. A lot.
Whatever the reason, when we recently got to take an Obsidian Black model out for a few hours, we couldn't help but notice how incredibly punchy the Sport is, whether bursting away from a stoplight or accelerating to pass on the highway. Sometimes we even slowed down a bit on the highway just to feel the seamless thrust of getting back up to speed. With the 2010 Roadster Sport, the EV grin is still in full effect.
As stated, the Roadster Sport starts at $125,500 – $19,500 more than the standard Roadster. For the extra dosh, you not only get the improved 0-60 mph time, but also the ability to set the suspension to one of ten different settings and black-finish forged wheels (16 inches in diameter up front, 17 in the rear) wrapped in Yokohama ADVAN A048 tires, the same shoes that come standard on the Lotus Elise Sport (the standard Roadster has to make due with less aggressive AD07s).
As electric car fans know, peak torque from any electric motor is available from exactly 0 rpm, and this is blindingly apparent in the Roadster Sport. Its electric motor produces 280 lb-ft of torque and has also received a healthy horsepower bump to 288 over the standard model's 248. Another change is a smaller PEM (Power Electronics Module). Here you can see how the new PEM only comes to within about a foot of the sides of the car. The last-generation PEM extended almost to the edge while still allowing the trunk to close."
