GT4 race spec McLaren 570S coming

GT4 is supposed to be the entry-level class of GT racing. McLaren’s idea of an entry-level racer is a mid-engined, twin-turbo monster.

The rules stipulate that GT4-spec machines run quite close to production spec. The McLaren 570S GT4 features a (huge) bolt-on front splitter, rear wing and diffuser, all which generate consequential downforce. The interior will be stripped back with the regulation rollcage, race seat and harness added back in.

Power comes from the same twin-turbo, 3.8-litre V8 engine as the road car, though in race trim it will probably be detuned from the standard 562bhp. Like the big-boy GT3 and GTE classes, GT4 is subject to a Balance of Performance system that equalises lap times across the highly diverse machinery that competes in the class. The main competition the 570S will face will be the Porsche Cayman Clubsport, Aston Martin Vantage, KTM X-Bow and Maserati GranTurismo.

But the extra downforce with race-grade suspension, brakes and tyres should make up for the power deficit. One car will contest the British GT Championship this year – run by Ecurie Ecosse – before going on sale in time for the 2017 season. Though the British GT campaign is ostensibly an extended test session, we wouldn’t be surprised if the 570S turns out to be the class of the GT4 field.

As for price, the 570S GT4 will cost £159,900, 16 grand more than the road car. That’s actually quite a lot for GT4 car, but not that much for a track-ready supercar.

Meanwhile, McLaren is also working on a 570S Sprint, which is essentially the GT4 if it were completely free of FIA constraints. There’ll be a road-going LT version at some point, too.
