At the very top of the Sports Series, the 600LT is the McLaren to have. Be it the coupe or hardtop convertible, it’s one hell of a supercar and a thriller in the twisties. But in a few months’ time, the 620R will enter the scene with no fewer than 620 PS (612 horsepower) from 3.8 liters of displacement.
The British automaker shouldn’t have too much of a problem to find those ponies if you remember the M838T develops up to 675 PS (666 horsepower) in the 675LT. The Super Series currently relies on the M840T, a comprehensive evolution of the 3.8-liter engine based on the Nissan VRH35L co-developed with Tom Walkinshaw Racing for the R390 GT1 prototype racing car.
McLaren Automotive collaborated with Ricardo to modify the VRH35L for the MP4-12C, and the rest is history. It’s possible for the engine to rev that little bit more in the 620R as opposed to the 8,500-rpm limiter of the 600LT if McLaren can make a case for a few upgrades to the internals.
For reference, the 570S GT4 racing car and 570S MSO X special edition both stop at 8,500 rpm. The matte-black prototype in the photo gallery doesn’t feature the rear deck of the real deal we’ve covered in a previous story, but nevertheless, make no mistake that’s a test mule for the 620R.
Ginormous carbon-ceramic brake rotors, red brake calipers, 10-spoke wheels with center-locking nuts, and a carbon-fiber rear spoiler are featured, along with two nostrils in the frunk, a deeper lip spoiler up front, and carbon-fiber canards on each side of the front bumper. What boggles the mind is the roof-mounted scoop, which might be there to channel air to the twin-turbo V8.
A quick glance at the rear of the prototype reveals misaligned panels and engine bay hardware, as well as the standard exhaust outlets instead of the rear deck-exiting tips of the 600LT and 570S GT4 racecar.
Even though it looks like an endurance racing car, the 2020 McLaren 620R is a road-legal supercar. To this effect, you shouldn’t look forward to slick Pirellis on all four corners. The Pirelli Trofeo R should be more than adequate for a road-going model, featuring a motorsports-inspired compound with an ultra-low profile and asymmetric tread.
