[1][2][9] At the 2015 Shanghai Motor Show, the entry level McLaren Sports Series car named 540C was unveiled with 533 hp (540 PS; 397 kW) and 540 N⋅m (398 lb⋅ft) of torque.

This new entry-level model focuses on "day-to-day usability and driveability" even more than that of the 570S with improved city driving and ride quality.

[citation needed] At the 2016 Geneva Motor Show, McLaren presented another addition to the Sport Series and 570 line up, dubbed the 570GT.

Announced online in early 2016, and making their public debut at the Goodwood Festival of Speed, the 570S GT4 and 570S Sprint are the track oriented iterations of the 570S.

The two-piece aluminium roof folds into a compartment located behind the seats of the car leaving the rear buttress in place.

The drivetrain of the Spider remains identical to that of the coupe which results in similar performance to the coupé counterpart with the roof up.

The Spider has new forged aluminium wheels and three special launch colours namely Vega Blue, Sicilian Yellow and Ventura Orange.

The interior of the car is also designed to simulate the GT4 racer without taking away the creature comforts and includes exposed carbon fibre monocell throughout, carbon fibre racing bucket seats with customizable six point racing harness, Alcantara interior trim and a carbon fibre bulkhead located at the rear to store the helmets of the occupants while keeping the air conditioning system, parking assist, front lift system and GPS navigation system as standard equipment.

Another distinguishing feature of the 600LT is the lightweight titanium exhaust system which is mounted on top of the rear of the car which harks back to its original application in the Senna.

The 3.8-litre twin-turbocharged V8 engine utilised in the 600LT is tuned to produce a maximum power output of 600 PS (441 kW; 592 hp), hence the 600 in the name, and 620 N⋅m (457 lb⋅ft) of torque.

Due to the use of the same carbon monocoque as the other models in the 570S lineage, the 600LT Spider did not require any extra modifications to incorporate a folding hardtop roof.

The car shares its Monocell II carbon fibre monocoque chassis with the 570S GT4 race car as well as the engine which, not subject to racing restrictions and ECU changes is now rated at 620 PS (456 kW; 612 hp) and 620 N⋅m (457 lb⋅ft) making it McLaren's most powerful sports series model.

Other changes include semi-slick Pirelli P zero Trofeo R tyres with track only Pirelli racing slicks being optional, a bare minimum racing interior with the carpeting removed, carbon fibre racing seats with six-point harness, door pull straps, carbon fibre shift paddles, 12 o'clock mark on the steering wheel, McLaren Track Telemetry system (MTT) and deletion of air-conditioning and infotainment system; although they are available as no cost options, adjustable coilover motorsport dampers; which feature 32 individual settings per corner to allow the driver to tailor rebound and compression rates to their preferred settings, stiffer anti-roll bars have and track-focused carbon-ceramic brakes with 390 mm brake discs Arther front and 380 mm brake discs at the rear with forged aluminum calipers.

The adjustable rear wing made from carbon fibre is shared with the 570S GT4 and allows the 620R to generate 185 kg (408 lb) of downforce at a speed of 250 km/h (155 mph).
