The hand-built carbon fiber Tesla roadster has been upgraded, redefined and slightly redesigned resulting in the roadster sport model. As with the basic roadster, expect effortless acceleration to 125 mph top speed. However, the newer sport model will take you from 0 to 60 in a mind-numbing 3.7 seconds (rather than 3.9 seconds) with the same liquid-cooled 56 kWh Li-on battery pack consisting of 6,831 cells. This 288 hp high-performance two-seater electric beauty will charge in 3.5 hours via a 240/70 charger and has the capability of charging at any 120 volt outlet. The roadster sport's 295 pounds of torque makes for breath-taking acceleration -- acceleration that has to be experienced to be fully appreciated. Both the basic roadster and the roadster sport flaunt restyled Lotus Elise bodies built in the UK. The drivetrain and electronics were installed at Tesla Motors' headquarters in Palo Alto, California.
