McLaren MP4-12C

The 12C also sports an advanced suspension management system called Proactive Chassis Control, which is said to offer the comfort of an executive sedan but with unseen levels of roll control and grip.

The suspension is based on double wishbones with coil springs. The dampers are interconnected hydraulically and provide adaptive responses depending on both road conditions and driver preference.

The Proactive system features adjustable roll control which replaces the standard mechanical anti-roll bars. There are three suspension modes that are selected on the Active Dynamics Panel. There is a 'normal', a 'sport' mode and a high performance mode which adjusts numerous parameters in the system.

Another feature that helps the 12C to handle at a new level is a development of an electronic system used by McLaren's 1997 MP4/12 Formula 1 car--Brake Steer. In essence, it is a system that brakes the inside rear wheel when the car is entering a corner too quickly to make the desired radius. Under normal circumstances the front would wash away wide of the apex the driver wants to touch: in other words, the car is in a state of understeer.

Brake Steer manages the tendency of a car to wash out and brings its nose back on line. It assesses the steering angle to determine the driver's intended course and applies the inside rear brake to increase yaw rate and resume the desired course.

The system also works on acceleration out of a corner when the inside rear has a tendency to spin, allowing the driver to put power down more quickly. It controls what a limited slip differential would do and obviates the need for such a complex and heavy unit, thus saving more valuable kilos.

Inside, the 12C comes with plenty of luxury including the world’s first Meridian car stereo, an advanced steering wheel, plus a full quota of airbags, fully automatic dual zone climate control, sophisticated telematics and audio systems, parking sensors, trip computer, cruise control and electric memory seats.
