This is going to be a fun one to drive in a race track

Gordon Murray Automotive has revealed the track version of the McLaren F1-inspired T.50 supercar. It’s called the GMA T.50s Niki Lauda, named after the three-time F1 world champion. GMA developed the T.50s Niki Lauda with the goal of turning it into the be-all and end-all for a track car. It comes with a 4.0-liter naturally aspirated V-12 engine that produces 89 fewer horsepower than the McLaren Senna GTR, but weighs 30 percent lighter and generates 50 percent more downforce than the McLaren track car. GMA plans to build only 25 units of the T.50s Niki Lauda. Each unit is priced at $4.3 million, and production is set to begin at the end of 2021.

Though it shares some similarities with the road-going T.50, including a carbon fiber monocoque, the track-spec T.50s Niki Lauda is a different model.

All the carbon fiber body panels are different, including all the aerodynamic components that the T.50s carries.

The aerodynamic hardware is the calling card of the T.50s. It comes with a front splitter with a central aerofoil section, dive planes, and barge boards. There’s also a large dorsal fin that’s connected to a massive rear wing. An equally massive rear diffuser sits under the rear bodywork, and just above it is the same 15.7-inch ground-effect fan that the T.50 also has.

With all the weight savings elements in place, the T.50s Niki Lauda weighs just 1,878 pounds. It’s almost 300 pounds lighter than the T.50. Despite that, all the aero pieces help the track-spec unicorn whip up 3,300 pounds of downforce at high speed. That’s 1,100 pounds more than the Senna GTR.

The no-frills interior comes with a racing seat with a six-point harness that’s set up in a central driving position. A rectangular carbon fiber steering wheel sits in the middle and the single digital screen shows only important driving information. A large panel sits to the right of the driver. That’s where all the buttons and switches are located.

The Cosworth-built 4.0-liter naturally aspirated V-12 engine is a revised version of the same engine that powers the T.50.

Titanium inlets and exhaust valves are present in the engine of the T.50s Niki Lauda, as is a race-car ram-air intake system with 12 throttle bodies, and a straight exhaust made from Inconel. Cosworth also modified the cylinder heads, boosting the compression ratio to 15:1. The variable valve timing system present in the road-going T50 is not available in the T.50s Niki Lauda.

The redesigned V-12 produces 725 horsepower and 357 pound-feet of torque. It’s more powerful than the road-going T.50 by 71 horsepower and 13 pound-feet of torque. The T.50’s V-12 unit produces 654 horsepower and 344 pound-feet of torque. Mated to the engine is a six-speed Xtrac paddle-shift transmission. Acceleration times for the T.50s Niki Lauda have not been announced, but the supercar is expected to reach a top speed of 210 mph.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
