For the 2009 season we have the new Vodafone McLaren MP4-24 which represents a significant departure from its world championship-winning predecessor. The engineers have tried to make the best out of it and so offered a sophisticated kinetic energy recovery system and a lot more. The aerodynamic regulations were framed by the FIA and the Overtaking Working Group which met throughout 2007 in order to address the issues affecting passing Formula 1. The KERS device found on the McLaren MP4-24 has been developed in collaboration with McLaren and Mercedes-Benz High Performance Engines, which has been developing and refining the system for almost two years now. With a full optimized KERS device, the model is capable of generating more power. The main focus of the team has already shifted to further improving the integration of the unit within the chassis in order to minimize performance loss elsewhere within the package. The new package is expercted to deliver a 0.4-0.6 s gain per lap.
With an unprecedented series of rule changes introduced ahead of the 2009 season, the new Vodafone McLaren Mercedes MP4-24 represents a significant departure from its world championship-winning predecessor.
Incorporating new bodywork regulations and the much-heralded return of slick tyres, the teamâ€™s new challenger not only looks radical but also incorporates a host of new innovative features under the skin, such as a sophisticated kinetic energy recovery system (KERS).
Introducing the MP4-24
While still retaining the distinctive family look established with both the MP4-22 and MP4-23, this yearâ€™s car is visually very different from its predecessors as a result of two main factors:
This yearâ€™s aerodynamic regulations were framed by the FIA and the Overtaking Working Group (helmed by Vodafone McLaren Mercedes engineering director Paddy Lowe, Ferrariâ€™s Rory Byrne and Renaultâ€™s Pat Symonds) which met throughout 2007 in order to address the issues affecting passing in Formula 1.
The OWGâ€™s influence can be most clearly seen around the front wing, which has been widened to increase front-end load when following another car, and the rear wing â€" which is now more compact to offer less interference to chasing vehicles. Other factors affecting aerodynamics include the banning of ancillary appendages, the addition of driver-adjustable front-wing flaps and a heavily revised diffuser.
The MP4-24â€™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. With a fully optimised KERS deviceâ€™s output capped at 60kW/400kJ (discharging an additional 80bhp for 6.66s per lap), the development teamâ€™s primary focus has already shifted to further improving the unitâ€™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 0.4-0.6s gain per lap.
