In anticipation of the revealing of Gordon Murray Automotive’s T.50 supercar on August 4, the British firm has supplied particulars of the Cosworth GMA V12 engine that can propel the newest creation of the previous McLaren designer.
Solely 50 such engines might be produced and Murray Automotive guarantees they would be the “world’s highest revving, quickest responding, most energy dense, and lightest naturally aspirated V12 highway automobile engine” thus far.
Although impressed by System One racing engines, the Cosworth GMA V12 “doesn’t share a single half with another engine,” based on the information launch. A bespoke 6-speed Xtrac H-pattern guide transmission might be linked to these 3.9-liter engines.
“Greater than half of any actually nice driving expertise is delivered by the engine, so proper from the beginning I set the very best attainable benchmark – to create the world’s biggest naturally aspirated V12,” Murray is quoted within the announcement.
“To be actually exceptional, an engine must have the precise character; extremely responsive, a tremendous sound, partaking torque supply, free-revving, and it must be naturally aspirated. For all these causes, the engine within the T.50 was by no means going to be something apart from a V12.”
A key a part of the T.50 engine design was to maintain it as small as attainable, Murray Automotive mentioned.
“The unique inspiration for the engine stemmed from the three.3-liter V12 powering the legendary Ferrari 250 GTO – small capability, characterful and highly effective,” the corporate defined.
“With a transparent view on the required acceleration and torque, and the aim of a sub-1,000kg complete car weight, Cosworth proposed the capability may very well be simply 3.9-liters whereas nonetheless reaching supercar efficiency.”
Efficiency targets included the engine in Murray’s famed McLaren F1 highway automobile and the engine that spins to 11,500 rpm in his Gentle Automotive Firm “Rocket.” The Cosworth GMA V12 is rated at 663 horsepower at 11,500 rpm and 344 pound-feet of torque at 9,000, with 71 % of most torque obtainable at 2,500 revs, “key to making sure day-to-day drivability.”
Boosting the general energy obtainable within the T.50 is a 48-volt built-in starter-generator and “motorsport slipstream expertise and ram air induction” that give efficiency yet one more enhance.
“The factors and benchmarks set by Gordon for the T.50 engine comprised one of many hardest engine briefs we’ve ever taken on,” mentioned Cosworth managing director Bruce Wooden. “It pushes the boundaries in each course and it’s a real thrill for everybody at Cosworth to be half of what’s going to certainly change into as fabled a car as Gordon’s McLaren F1 earlier than it.”
“Each element on this automobile is a chunk of engineering artwork, and the engine isn’t any exception,” Murray added.
“I needed the engine to appear to be a contemporary interpretation of a 1960s V12. If it wasn’t the beating coronary heart of the T.50 it might make a wonderful, sculptural modern-art set up.”
