Gordon Murray’s successor to the McLaren F1, the upcoming GMA T.50 supercar, takes advantage of hypercar territory by offering the best power-to-weight ratio in addition to the revolutionary aero active in a three-and-a-half-engine carbon fiber package . What is claimed to exceed 650 horsepower and 332 pound-feet of torque comes courtesy of a custom-built, naturally aspirated 3.9-liter V12. And now, you can hear all of that in action, even if it’s limited.
England’s alloy DOHC engine is sure to fill up with machined internal components made of titanium and other expensive metals making it capable of accelerating to 12,100 rpm, thus beating the Aston Martin Valkyrie’s 6.5-liter V12 at roughly what is idle speed. of a standard road car. Aston’s 1,000-horsepower engine, also manufactured by Cosworth, is ready to cut its fuel to 11,400 rpm.
What Gordon Murray Automotive claims to be “the fastest responding naturally aspirated V12 ever made for a road car” was first tested as a three-cylinder, exceeding the team’s power and torque expectations as early as March. . Now, Cosworth has finished building its first full-size test engine, with the 3.9 V12 running at 1,500 rpm before the big boost of 12,100 rpm. At 1,500 rpm tied to a test bench, the GMA-Cosworth V12 sounds pleasantly eager.
GMA uses a relatively compact 3.9-liter V12 instead of something bigger to save weight as it has decided not to enter the constantly increasing horsepower game. Professor Murray claims that this V12 weighs less than 397 pounds, making it not only more powerful than BMW’s F1-supplied 6.2-liter V12, but also about 132 pounds lighter. As expected, they are quite proud of this achievement:
The GMA T.50’s V12 will send its power through an equally new six-speed manual gearbox, designed and built by motorsport specialist Xtrac. Labeled “CPA,” this smart package transmission is 22 pounds lighter than the McLaren F1’s six-speed transmission, helping GMA with its 2,160-pound total weight goal. Let’s not forget that the T.50’s titanium pedal box is also 10.58 ounces lighter than the $ 20 million F1. Good value then.
