The Saleen FourSixteen is a tuned version of the all-electric Tesla Model S that made its debut last summer at Pebble Beach. Based on the P85 Performance version, it boasted revised adjustable suspension, new final gear ratio, a unique locking differential and sporty seats and came with a price tag of US$152,000.

The car was named the FourSixteen as a reference to the 416HP output of the Model S. Now that Tesla has introduced the 691HP P85D, though, the tuner decided that the name was no longer applicable. Thus, it gave its model the designation of ST, which is short for Saleen Tesla.

While it will continue delivering FourSixteen vehicles that have been ordered, Saleen is now offering a complete lineup of Model S-based models. The base 380HP version is the ST380 and the 691HP P85D is the ST691.

Saleen’s modifications over the stock Tesla saloon include suspension upgrades, a modified interior, carbon ceramic brakes and that final gear ration that reduces the already impressive 3.2-second 0-60 mph time to a nice, round 3.0 seconds. Prices before federal and/or state incentives start at US$132,000 for the base ST380 and rise to US$164,600 for the range-topping ST691.
