McLaren has lifted the lid on its 720S Spider hardtop convertible that pairs a mid-mounted 537kW/770Nm 4.0-litre twin-turbo petrol V8 with unlimited headroom.
However, the sprint to 200km/h is knocked down in 7.9s and the standing quarter mile is achieved in 10.4s, both 0.1s slower than its Coupe sibling.
Meanwhile, top speed is a Coupe-matching 341km/h with the roof up, while open-air motoring will only allow a terminal velocity of 325km/h.
Built around the brand’s 'Monocage-II-S' carbon-fibre core, the 720S Spider requires none of the additional strengthening usually required when removing the roof.
However, rollover protection is still afforded thanks to carbon-fibre structural supports embedded into the Moncage-II-S and rear flying buttreses, which are now positioned higher to reduce turbulent air intruding into the cabin.
As such, the 720S Spider is just 49kg heavier than its fixed-roof sibling, at 1332kg.
From the front, the Spider largely mirrors the Coupe in design including signature dihedral doors, contoured bonnet, slimline headlights and a thin windscreen.
However, the rear is tweaked to accommodate the one-piece retractable hardtop, which can open and close in 11 seconds at speeds up to 50km/h.
The roof can also be optioned with a glazed glass component, which is electrochromic and can be turned opaque or transparent with the push of a button.
Mirroring the interior of the 720S Coupe, the Spider is equipped with a centrally mounted 8.0-inch multimedia system, dual-zone climate control, sports bucket seats and three handling modes – ‘Comfort’, ‘Sport’ and ‘Track’.
Australian availability, timing and pricing are yet to be revealed, but for comparison, the 720S Coupe costs $515,080 before on-roads.
