The drop-top version of the 600LT Coupe is at least 80 kg lighter than the competition, says McLaren. With just 50 kg premium over the Coupe, the dry weight of the Spider is still 1,297 kg.
Furthermore, no additional strengthening is required to maintain full structural rigidity, thanks to a strong carbon fibre MonoCell II chassis.
As for the roof, the three-piece, powered retractable hardtop can be operated at speeds of up to 40 km/h (25 mph). An electrically-operated, glazed wind deflector can be activated independently of the hardtop, to reduce buffeting or increase ventilation – or simply to allow more of the exhaust sound into the cabin. When the roof is up, the tonneau storage area provides an additional 52 litres of luggage space.
The 3.8-litre V8 twin-turbo produces the same 592 bhp and 620 Nm of torque as in the Coupe. The 600LT Spider is claimed to reach 100 km/h (62 mph) from a standstill in 2.9 seconds, with 200 km/h (124 mph) achieved in just 8.4 seconds – a 0.2 second slower than the Coupe. The top speed is 324 km/h (201 mph) with the roof raised, or 315 km/h (196 mph) when lowered.
