Just when you thought the Model S could not get any more extreme, Tesla handed it over to Steve Saleen, the man behind several unhinged Mustangs and the S7 supercar, to work his magic.

The result? A trimmed, lightened and smoothed-out version of the existing electric sport sedan, called the FourSixteen; Saleen says the name comes from the car’s horsepower output, 416.

Initially unveiled at the Concours d’Elegance in Pebble Beach, Calif., the FourSixteen is subject to several upgrades, including a tuned suspension system, bigger brakes and bigger wheels, as well as a modified hood and front fascia to improve aerodynamics.

Under the hood, cooling gets a substantial going-over, such as a bigger radiator, more powerful fans and a high-flow water pump. Engine output remains at 416 horses, but don’t let that get you down — Saleen changed the transmission’s final gear ratio to 11:39:1, which means faster off-the-line acceleration.

Carbon-ceramic brakes are an optional extra, including 6-piston calipers up front, giving it an even beefier look. In total, Saleen says the brake mods equaled to roughly 30-pounds saved at each corner.

Every bit helps when gunning for top-notch performance, notes Saleen.

“We’ve turned our attention to electric vehicles because we realize they are not a fad and are here to stay,” Saleen said. “We wanted to provide more of a performance driving experience,” he added, while hinting that the FourSixteen could very well be a challenger for Mercedes’ AMG monsters.

All without drinking a single drop of fuel.

Price for all this extra high-voltage fun? The Saleen FourSixteen starts at $152,000 for the complete vehicle which includes the base P85Model S sedan and 4-year / 50,000 mile warranty.

According to a company statement, this is priced before existing state and federal EV incentives which can range from $7,500 to $15,000 depending on the buyers state (i.e. A California resident would pay $142,000.00).

So. Green-clean and fast as hell. Good combo, no?
