McLaren 675LT Spider revealed

McLaren 675LT Spider revealed

Open-top version of Woking's hardcore supercar breaks cover

Initially, McLaren said it would offer one new model every year. It’s significantly over-delivered in 2015, though, with the new 675 'Long Tail' Spider its fifth reveal of the year.

Unsurprisingly, it’s based heavily on the 675LT Coupe released earlier in 2015. Limited to 500 examples worldwide, the Spider’s European pricing carries a 10 per cent premium over its hardtop sibling, which will put it in the ballpark of $675,000 locally.

It may look very similar to the 650S Spider, however the engineering changes under the skin are significant. At 1270kg (dry), it drops 100kg, though weighs 40kg more than the Coupe due to the retractable hard-top roof.

Like all McLarens the engine is a 3.8-litre twin-turbo V8, however so many components are bespoke to the 675LT (around 50 per cent compared to 650S) that the engine receives its own code – M838TL.

Outputs are unchanged from the Coupe, meaning 497kW (a devilish 666bhp) at 7100rpm and 700Nm from 5000-6500rpm.

With its focus on track performance, the 675LT Spider is significantly stiffer, with spring rates 27 per cent stiffer at the front and 63 per cent at the rear, which has allowed for a 40 per cent increase in downforce over the 650S courtesy of the larger front splitter and extended airbrake which lends it the ‘Longtail’ name.

The front tracks are 20mm wider, while the staggered ultra-lightweight forged wheels (19s front, 20s rear) wears Pirelli’s P Zero Trofeo R tyres.

Nonetheless, until Ferrari reveals the inevitable 488 Speciale sometime in the future, nothing short of a P1 or 918 Spyder can touch the 675LT’s performance, which means it’s currently in a class of its own.
