The track-only McLaren 650S Sprint will be one of four models that the specialty British car maker will debut at this year’s Pebble Beach Concours d’Elegance.
Mounted behind the passenger cell is a twin-turbo 3.8-litre V8 shared, by and large, with the road-going 650S. Although both the engine and transmission are said to carry a unique calibration, McLaren has yet to state how much power the Sprint has or how quickly it can go.
For reference, the regular 650S has 478kW of power and 678Nm of torque at its disposal. By sending power to the rear wheels via seven-speed automatic transmission, the road-going car can hit 100km/h in 3.0 seconds, 200km/h in 8.4 seconds and 300km/h in 25.4 seconds.
Being a track-focussed model, the 650S Sprint does away with most of the trappings of a modern car. In their place is a FIA-compliant roll cage, lightweight carbonfibre racing bucket seats, a six-point harness for the driver, and a standard-fit fire extinguisher. To keep the driver cool in even the harshest conditions, the Sprint retains the 650S’ air conditioning system.
Other changes include quick-fill connectors and a larger fuel tank, bigger radiator, reworked active aerodynamics system, uprated braking package, lowered suspension with retuned adaptive damping, 19-inch centre-locking alloy wheels, and an air-jacking system that allows for prompt tyre changes.
Most of the revisions to the 650S’ body work are said to be done in the name of greater downforce and improving the delivery of cool air to the car’s various components.
The 650S Sprint can ride on either slick or wet tyres. Options include a carbon fibre front splitter and rear wing, a lightweight polycarbonate windscreen and a six-point harness for the passenger’s seat.
