McLaren has announced a package of enhancements for its MP4-12C that makes the supercar “even more invigorating to drive yet even easier to live with”. Headlining the changes is a 25 PS power increase for the mid mounted, 3.8 litre twin-turbocharged V8 engine, which now makes 625 PS. The new engine mapping has not altered the MP4-12C’s efficiency – it does 11.7 litres per 100 km in the EU combined cycle.

McLaren also tweaked the seven-speed SSG transmission for crisper throttle response and improved clutch control for gear changes that are both faster and smoother.

The MP4-12C’s Intake Sound Generator (ISG) that controls the amount of engine intake sound heard in the cabin, is now programmable across three levels in all three Powertrain modes (Normal, Sport, Track). With the 2013 spec 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.

Ease of use is improved through a host of detail changes. A small button mounted on each door replaces the touch sensor system, based on customer feedback. To improve safety, an enhancement will be made to the headlight activation settings – with the ‘AUTO-lights’ mode selected, the 12C’s headlights will be automatically switched on when rain is detected.

The climate control will have a new ‘AUTO LO’ setting – lower fan speeds, quieter cabin. A wider variety of paint, leather and wheel options give customers yet more scope for personalisation. The McLaren logo, called Speed Marque, has been subtly revised.

All the above revisions will be available to existing customers, at no cost.
