It was back in August that Saleen first unveiled its modified Tesla Model S, which the company had named a FourSixteen in reference to the donor Model S P85’s 416-horsepower rating. But just a few months later Tesla Motors [NSDQ:TSLA] introduced its own 691-hp Model S P85D as the replacement for its P85, meaning Saleen’s FourSixteen name no longer made any sense.

Instead of abandoning the project, Saleen decided to offer its Model S modifications, such as its aero components, new final gear ratios and new locking differentials, on additional Model S variants, and in the process renamed its car the ST, short for Saleen Tesla.

Saleen will still deliver previous orders for the FourSixteen based on the Model S P85, but at the same time it’s taking orders for its new 2015 ST lineup based on the latest Model S variants: the ST lineup includes modifications for the Model S’s rear-wheel-drive 85 variant plus the new dual-motor, all-wheel-drive P85D.

No changes have been made to the cars’ outputs, so Saleen’s ST version of the 85 model is rated at a stock 380 hp and is called the ST380. The ST version of the P85D is rated at a stock 691 hp and is called the ST691.

The arrival of Saleen’s ST range brings a few extra mods, too. These include new suspension upgrades, a fully modified cabin with 2+2 seating, and carbon ceramic brakes. Incredibly, with Saleen’s final gear ratio mods, the ST691 model will sprint to 60 mph from rest in under 3.0 seconds! The stock P85D takes 3.2 seconds to achieve the same feat.

Pricing for the 2015 Saleen ST380 starts at $132,000, while the 2015 ST691 will set you back a hefty $164,600.
