RML, famous for its championship-winning touring and GT racecars, has launched a new car, the GT Hypercar (GTH). The GTH is based on Porsche’s 992 911 Turbo S but features new bodywork that can produce 662kg of downforce at 150mph. 

Naturally, the engine has been upgraded too. Litchfield Motors was enlisted to tease out 920hp and 1000Nm of torque from the car’s flat-six engine. The GTH is limited to 39 examples and will cost in excess of half a million pounds.
