Luxury automaker McLaren‘s more exclusive, limited-edition supercars aren’t around for long. Their newest track-ready build will only be in production for a year.

The sleek and just plain sexy 2019 McLaren 600LT is something like a track-ready version of the 570S, but it is one of just four vehicles to earn the LT (Longtail) designation. Taking inspiration from previous LT supercars, this 600LT features an ultra-lightweight build and plenty of power under the hood.

Thanks to extensive use of carbon fiber for shell and body panels, the vehicle weights in at 211.6 pounds less than the 570S. The lighter body paired with a twin-turbocharged 3.8-liter V8 engine results in unparalleled power and response on the track.

The 600LT’s V8 produces 592 horsepower and 457 pound-feet of torque. All that power is also due in part to an updated titanium exhaust system that helped cut weight even more. Drivers will benefit from performance updates that include stiffer engine mounts, a faster steering rack, and the option of adding a carbon fiber roof.

Although a set production limit hasn’t been announced, McLaren did make it clear that it will only produce the 600LT from October of this year to October of 2019. Information about pricing for U.S. customers hasn’t been revealed as of yet.
