Stig vs the 12C Spider
The rear tonneau can be electrically raised independently of the roof, and inside each hollow buttress is a neatly rolled soft bag. Unfurl them, pack them with squidgy stuff and they're shaped to fit the vacant roof space. And there you have it - another 52 litres of luggage capacity.
But enough of the practicalities of this car. The Spider comes with the same updates as the 2013 coupe, which essentially means a bit more power (a 24bhp climb to 616bhp) for the 3.8-litre twin-turbo V8, plus an extra 500rpm to play with at the top end of the rev band. Personally, I think it's just as noteworthy that this is the first McLaren I've driven with working satnav. Like everything else the firm does, it works cleanly and logically, has a simple interface and the portrait-orientated screen makes you wonder how soon others will follow McLaren's lead.
