McLaren Automotive has revealed the convertible version of its latest model, the McLaren 650S, unveiled at the Geneva Motor Show.
The 650S Spider is mechanically identical to the 650S Coupe and is fitted with the same M838T twin turbo V8 engine, producing 641 bhp and 678 Nm (500 lb ft). This results is a 62 mph sprint of 3.0 seconds, identical to the Coupe, and 124 mph is reached in 8.6 seconds, just 0.2 seconds shy of the fixed-head model. Maximum speed is 204 mph. Fuel consumption and emissions remain the same for the Spider, returning 24.2 mpg on the EU combined cycle and 275 g/km.
McLaren says the 650S’s carbon-fibre MonoCell chassis requires no additional strengthening or reinforcing in open-top guise, and gives the Spider identical handling and ride, and virtually identical straight-line performance figures. The overall weight of the 650S Spider is 1,370 kg (dry), an increase of 40 kg over the Coupe, with this additional mass coming from the retractable hard top and roof mechanism.
The two-piece retractable hard top can be automatically raised or lower in under 17 seconds, and can be activated while stationary or at any speed up to 19mph.
As with the 12C Spider, the 650S Spider uses a heated glass rear window, operating independently of the roof. With the roof down, the rear window is designed to act as a wind deflector, reducing cabin buffeting. Roof up, the rear screen can be lowered to allow more engine noise into the cabin. When down, the roof is stowed beneath a body-coloured hard tonneau cover incorporated in the twin rear buttresses. With the roof raised, the area beneath the tonneau cover can be used as additional luggage space.
