Headphones on: this is the V12-engined GMA T.50s at 12,000rpm

Gordon Murray’s modern interpretation of the McLaren F1, the GMA T.50 road car, is sublime – and now there’s a version only for the track. 

It’s lighter, louder, faster, more downforce hungry and 100 per cent less road legal, and in this world-exclusive video review of the new GMA T.50s Niki Lauda, Jethro Bovingdon drives it flat-out at a Formula 1-grade race circuit. Volume up, too, for the unfettered 761bhp V12 that revs to over 12,000rpm!
