The 675LT Spider, only the second McLaren in nearly two decades to wear the LT – or ‘Longtail’ – name, stays true to the spirit of its iconic predecessor with aerodynamically optimised, dramatically enhanced styling that results in 40 percent more downforce than the 650S Spider which it sits alongside in the McLaren Super Series.
Under the skin sits the heavily-revised 3.8-litre twin turbo V8 powertrain from the Coupé sibling, ensuring performance figures are worthy of the LT badge. The power output and torque figures remain unchanged, with 675PS (666 horsepower) delivered at 7,100rpm and 700Nm (516 lb-ft.) available between 5,000-6,500rpm. The changes to the powertrain saw more than 50 percent of the components replaced to ensure optimised levels of power, torque and drivability. These include new, more efficient turbos, detail design changes to the cylinder heads and exhaust manifolds, new camshaft and lightweight connecting rods, and a faster-flowing fuel pump and delivery system.
Acceleration from 0-100 km/h (0-62 mph) takes just 2.9 seconds, and 200 km/h (124 mph) is achieved in 8.1 seconds – giving away only 0.2 seconds to the more aerodynamically optimised and lighter Coupé. Controlled torque delivery in first gear manages torque to 600Nm (443 lb-ft.) to ensure maximum acceleration, and minimising wheel slip. Top speed is 326 km/h (203 mph). Despite these blistering performance figures, the 675LT Spider returns 24.2mpg on the EU combined cycle, while CO2 emissions remain at 275g/km – the same as the Coupé. A three-piece retractable folding hardtop can be opened at speeds up to 40 km/h (25 mph) to allow for a new level of open-air exhilaration.
