Styled in the same vein as the coupé, the 675 LT Spider’s three-piece hardtop folding roof can be opened at speeds of up to 19mph, and is stored under a tonneau cover at the rear of the car when folded away. The open-top McLaren weighs in at 1270kg dry, a full 100kg lighter than the 650S Spider and 40kg heavier than the 675 LT coupé.
McLaren says that due to the inherent strength of its carbon tub, no further strengthening was needed to create the convertible.
Mechanically, the Spider features the same twin-turbocharged 3.8-litre V8 engine as the coupé, producing 666bhp at 7100rpm and 516lb ft of torque between 5000-6500rpm. Around half of the engine’s components were altered for the Spider, with new elements including more efficient turbochargers, redesigned exhaust manifolds and a lightweight camshaft and connecting rods added.
McLaren has succeeded once again in making its Spider variant match the coupé in terms of performance – the 675 LT Spider keeps the coupé’s 0-62mph sprint time of 2.9 seconds, and only loses 2mph in top speed terms, topping out at 203mph. McLaren says the new car can return up to 24.1mpg, with CO2 emissions rated at 275g/km.
