INTRODUCING THE MP4-24

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:

Aerodynamics

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.

KERS

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.

Winter test programme

With in-season track testing now prohibited, the MP4-24 will undergo an intensive winter programme at the following venues prior to the season-opening Australian Grand Prix on March 29:
Jan 19-22 Portimao Group test one
Feb 10-13 Jerez Group test two
Mar 1-4 Jerez Group test three
Mar 9-12 Barcelona Group test four
Week 12 Private test ahead of transportation to Melbourne

^^^Norbert looks as if he is wondering, "Can I eat one of those tires?"

I'm going out on a limb and saying the new cars will improve overtaking this season. The driver-controlled flaps and KERS momenary boost will impel the drivers to attack each other a little more.

I wonder what Dennis stepping down will do to McLaren's team dynamic this year.

wicked!

so what are all those buttons and switches on the steering wheel for?

..i know it can't be for changing statins and volume (or horn) :D

Those adjust the seat coolers and massagers. When you win a championship you get crazy perks the next year. :)

I've gotta say, I got use to the grooves in the tires. Now seeing the slicks looks funny and uglier, along with the new smaller wings and wider front wing. Just not pleasing to the eye.
