McLaren’s unshackled its 570S GT4 racer from motorsport regulations to create the McLaren 620R, a ludicrous limited-edition racer for the road.
It’ll build 350 units in total, all with a GT4-spec 3.8-litre twin-turbo V8 derestricted to push 456kW and 620Nm through its seven-speed dual clutch gearbox.
That’s more than any other McLaren in the Sport Series range, 600LT included, so the claimed performance is just as impressive.
From rest the rear-drive coupe will hit 100km/h in 2.9 seconds, 200km/h in 8.1 seconds and cross the quarter mile in 10.4 seconds.
McLaren has also upgraded its grip as well as its grunt. Lighter, two-way dampers feature at each corner, while some rubber mounts are replaced with stainless steel items for a more direct steering feel.
It also scores GT4-spec springs and roll bars. But they’re only the start of a motorsport makeover that adds massive carbon ceramic brakes and centre-locking wheels you can order with slicks for track work. Pirelli P Zero Trofeo R rubber is standard.
Then inside it’s goodbye to the carpet, glovebox, air-con, sat-nav and an audio system. Lightweight carbon fibre buckets also hold driver and passenger within the car’s Monocell II carbon fibre tub.
There’s also an adjustable carbon fibre wing along with the GT4-spec front splitter, bumper and bonnet that all have been tweaked to pass road regulations. You can even add a roof scoop to cool you down.

Other options include a lightweight Bowers and Wilkins audio system. But if you’re the type who likes to stand out, you can hand your 620R to McLaren’s Special Operations outfit to really go nuts.
They can replace the standard stainless steel exhaust with a titanium unit in Nano Black exhaust finisher or specify a specific colour for your race harness. You can also deviate from the standard McLaren Orange, Silica White or Onyx Black finishes.
Otherwise you can take one as it is for £250,000, which blows out to AU$481,000 against Australia’s weak dollar, and get a free trackday with an instructor thrown in if you’re based in the US or Europe.
