McLaren-Mercedes: The new MP4-23 

Vodafone McLaren Mercedes today presented the MP4-23, the team’s 2008 Formula 1 car, at the Mercedes-Benz Museum in Stuttgart. Dr. Dieter Zetsche, Chairman of the Daimler Board, and Ron Dennis, Chairman and CEO of the McLaren Group, welcomed all the guests to the official presentation, with Lewis Hamilton, who celebrates his 23rd birthday today, and Heikki Kovalainen joined on stage by Pedro de la Rosa and fellow test driver Gary Paffett to unveil the MP4-23. The car was completed yesterday and left the McLaren Technology Centre in the UK at around 18:00 GMT on Sunday and was driven in a Mercedes-Benz Actros to the Mercedes-Benz Museum in Stuttgart-Untertürkheim, having covered approximately 1000kms, arriving around 10:00 this morning.

Upon arrival in Stuttgart, the car was transported to the 53,000 sqm Mercedes-Benz Museum, one of the world’s largest and most renowned car museums. About 700 Mercedes-Benz employees from the nearby manufacturing plant Stuttgart-Untertürkheim had the opportunity to attend today’s event at the end of their early shift alongside the more than 400 media and other guests. The Mercedes-Benz employees had the opportunity to enter a draw of which the lucky winners were able to meet and spend some time with Lewis and Heikki.

Following today’s event the car will be transported to the Circuito de Jerez in Southern Spain, where on Wednesday 9thJanuary Heikki and Pedro will start the test programme with two MP4-23 chassis at a private test. The team will remain at the circuit for five track days, excluding the weekend. Lewis will drive the 2008 car for the first time on Thursday 10th January alongside Heikki.

MP4-23 FACTFILE:

The first design meeting for the MP4-23 took place back in November 2006 with early layout work starting in March 2007.

Wind tunnel work commenced in late May 2007.

Since then the MP4-23 has spent over 3000 hours being developed in the wind tunnel.

The first MP4-23 chassis was ready for bonding in mid November 2007.

Lewis Hamilton, Pedro de la Rosa and Gary Paffett had their provisional seat fittings for the MP4-23 back in September 2007. Heikki Kovalainen was fitted for his seat shortly after being announced as a Vodafone McLaren Mercedes driver.

The car build process for chassis 1 began in early December 2007 and was finished in early January 2008.

Throughout the development process 150 different engineers have been involved in the whole project in all disciplines.

14000 engineering man hours have so far been put into the MP4-23 development project.

A similar number applies to the manufacturing man hours involved to produce the MP4-23 in time for its track debut on the 9th January 2008.

The MP4-23 is an evolution of the MP4-22 and as such there is no significant visual difference currently, however between now and the first race in Australia there are planned upgrades on most of the aerodynamic surfaces, wings, bodywork, bargeboards and additional bodywork components.

Alongside the development of the 2008 challenger, concept work has been started for the 2009 car since November 2007, with the KERS project (energy storage) beginning a year ago.
