McLaren released a mega gallery of photos for the MP4-12C Spider along with a set of in-depth technical details. As you’d expect, there isn’t much to report on other than the folding roof mechanism and the fresh 2013 model year updates. McLaren originally designed the MP4-12C with the Spider in mind, so modifications to the carbon fiber MonoCell were unnecessary.
Of course, the MP4-12C Spider does lose some performance thanks to the loss of aerodynamic aid with the roof down and a slightly heavier setup. The folding roof mechanism adds an extra 50kg to the total weight. It’s made from aluminium and a composite material which gives a very high standard of paint finish alongside a lightweight panel. Compared to the 458 Italia, the modifications weigh 10kg less. Total weight for the 12C Spider is 1,376kg compared to the 458 Spider’s 1,430kg dry weight.
The mechanism for the 12C Spider takes around 17 seconds to fully retract and uses a single hydraulic pump. It can be used at speeds of up to 30km/h (19mph) and the tonneau cover can be used as additional luggage space when the roof is raised. Luggage is included as standard to fit this area. McLaren also fit a different exhaust system to the 12C Spider which weighs an extra 2kg.
The Spider also gets the 2013 upgrades which includes a 25hp power increase. It takes the maximum output of the mid mounted, twin turbocharged V8 engine to 625hp. Modifications have been made by McLaren’s engineers to the 12C’s engine and SSG transmission increasing responsiveness. The 12C’s unique Intake Sound Generator (ISG) system, which controls the amount of engine intake sound heard in the cabin, is now programmable across three levels in all three Powertrain modes allowing the driver to select the amount of aural drama he or she wants to enjoy, whatever the road.
A new door entry system is a feature of the new 12C. A small button mounted on each door replaces the 12C’s touch sensor system. In line with customer feedback, this modification is intended to simplify the user experience. The ability to unlatch each door using the 12C key fob will be retained. The 12C Spider also gets Vehicle Lift. The system allows the 12C to be raised front and rear for improved ground clearance. This technology permits the vehicle to be raised by up to 40mm at the front and 25mm at the rear, and may remain in position at up to 60km/h.
