2009 Mclaren MP4-24 steps up, Ron Dennis steps down

Here is Lewis Hamilton's new ride. So far, worries that the 2009 cars would be hideous seem to be unfounded, Both Ferrari and Mclaren have produced quite beautiful shapes and has Toyota. the only sour notes are these narrow rear wings that look odd from certain angles.

The end of an era is also marked by Ron Dennis' announcement he will step down as team manager. You will remember that there had been much speculation in the wake of the Mclaren "spygate" scandal but it was clear Dennis wanted to go out with a win so, after Hamilton's cliffhanger win, this is not entirely unexpected. Dennis, like Frank Williams and Bernie Ecclestone has been one of the titans of modern Formula 1, from team mechanic to building one of the world's premiere technology companies and was responsible for changing the face of the sport. Martin Whitmarsh will take over as team leader as of March 1.

Mclaren Launch on the web

While still retaining the distinctive family look established with both the MP4-22 and MP4-23, this year’s car is visually very different from its predecessors as a result of two main factors:


This year’s aerodynamic regulations were framed by the FIA and the Overtaking Working Group (helmed by Vodafone McLaren Mercedes engineering director Paddy Lowe, Ferrari’s Rory Byrne and Renault’s Pat Symonds) which met throughout 2007 in order to address the issues affecting passing in Formula 1.

The OWG’s influence can be most clearly seen around the front wing, which has been widened, and the rear wing – which is now more compact. Other factors affecting aerodynamics include the banning of ancillary appendages, the addition of driver-adjustable front-wing flaps and a heavily revised diffuser.


The MP4-24’s KERS device has been developed in collaboration with McLaren and Mercedes-Benz HighPerformanceEngines, which has been developing and refining the system for almost two years. The device enables the car to recover energy under braking, store the energy for a lap and release it when the driver presses a button on the steering wheel.

With a fully optimised KERS device’s output capped at 400kJ (discharging 80bhp boost for 6.7s per lap), the development team’s primary focus has already shifted to further improving the unit’s integration within the chassis in order to minimise performance loss elsewhere within the package.

An optimised KERS package can be expected to deliver a 0.3-0.5s gain per lap.
