McLaren Automotive, rather than resting on its laurels, has instead announced a package of enhancements that will make its 12C high performance sports car even more invigorating to drive yet even easier to live with.
Headlining the changes is a 25PS power increase. It takes the maximum output of the mid mounted, twin turbocharged V8 engine to 625PS (616hp) to give yet more vivid acceleration at track speeds with no loss in efficiency. Modifications have been made by McLaren's engineers to the 12C's engine and SSG transmission increasing responsiveness. Ease of use, a phrase not often associated with cars of this type, is further improved through a host of detail changes while a wider variety of paint, leather and wheel options give customers yet more scope for personalisation. 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. But one aspect that hasn't changed is the 12C's purposeful styling ... apart from a subtle revision to the McLaren Speed Marque badge, that is.
The suite of upgrades to the 12C specification from October 2012 includes enhancements to the 12C's engine and transmission, in addition to other functional attributes.
A focus on drivetrain development has given McLaren Automotive's engineers the opportunity to increase the 12C's 3.8-litre twin turbo V8 output from 600PS to 625PS. The redesigned engine mapping has not altered the remarkable efficiency of the M838T engine, with 12C CO2 emissions remaining at just 279 g/km, and fuel economy recorded at 24.2 mpg (combined).
Modification of the 7-Speed SSG transmission to which the 12C's high-powered engine is mated has resulted in crisper throttle response and improved clutch control for gear changes that are both faster and smoother.
The 12C features an innovative Intake Sound Generator (ISG). This system works by controlling engine intake noise within the cabin at differing levels, depending on the Powertrain mode selected for the car. Moving up through Normal, Sport and Track Powertrain modes enhances the aural drama and driving experience of the 12C, with engine noise in the cabin changing when throttle power is applied and revs increase. With the 2013 specification 12C, the driver will be able to select the level of engine noise delivered in each mode through an electronic menu accessible via the instrument cluster.
