The McLaren 570S Track Pack is a new track-focused version of the British carmaker's entry-level model.
It is offered as an optional extra and costs £16,500 on top of the standard car's £150,000 price tag. For your money you get aerodynamic changes, styling tweaks and weight saving measures.
The Track Pack name might sound like a hardcore stripped-out rival to the likes of the Porsche 911 GT3 RS, but McLaren is pitching it more towards the casual track day driver who still needs some on-road practicality.
It shaves 25kg from the standard 570S thanks to a lightweight interior package that includes lighter carbon-fibre bucket seats and Alcantara in place of leather, while new alloy wheels help shave more weight.
Visual upgrades include a dark 'Stealth' finish to the wheels and exhaust, while the roof is painted 'Dark Palladium'.
The rear wing is 12mm taller to improve stability at high speed, and McLaren claims it produces an extra 29kg of downforce at 150mph.
A track telemetry system is also fitted to the car, which can normally be found higher up in the range on the 675LT and P1 hypercar. It records lap times, sector splits and saves all of the data so drivers can analyse their performance once out of the car.
The 562bhp twin turbo 3.8-litre V8 remains the same, but with a 0-60mph time of three seconds and a top speed of 204mph, it's already plenty fast enough.
The Track Pack is available now with deliveries beginning early next year.
