The all-new McLaren MP4-12C Spider will be capable of 196mph with its innovative retractable hard-top roof down. The new open-top McLaren can match its coupé sibling from zero to 62mph - taking 3.1sec - despite having a 40kg weight penalty.
The MP4-12C Spider features a two-piece retractable hard-top that is stowed behind the seats when not in use. The compact design of the system lets the Spider keep the glass engine cover of the coupé.
The roof can be positioned up or down in 17 seconds and at road speeds of up to 19mph using a button on the centre console. A glass screen between the two buttresses can be operated independently of the roof. This can act as a windbreak with the roof down, or for ventilation with the roof up.
McLaren supplies two soft bags with the MP4-12C Spider that are designed to fit in the 52-litre storage space behind the seats when the roof is up. McLaren managing director Antony Sheriff briefed the Woking outfit to ensure that the MP4-12C lost none of its usability in becoming a Spider.
Power for the Spider comes from the same 616bhp 3.8-litre V8 as the coupé, the only power output you can get for the MP4-12C after last month’s revisions to the coupé.
The Spider matches the coupé’s 0-62mph time but takes 0.2sec longer to get from zero to 124mph (9.0sec). The top speed of 196mph with the roof down increases to 204mph with the roof up.
The Spider also shares its lightweight carbonfibre Monocell chassis with the coupé. McLaren says that no extra strengthening has been needed for the Spider. Rollover protection is incorporated into the buttresses.
Other tweaks for the Spider include an audio system that adjusts its volume and tone according to whether the roof is up or down, and a revised climate control system that also adjusts to compensate for the outside elements.
