Martin Whitmarsh, McLaren team principal, said the team "had not done a good enough job". The car came under much scrutiny from team members and other critics alike. In testing, the MP4-24 was proven slower than its rivals due to aerodynamic problems, with Lewis Hamilton and Heikki Kovalainen repeatedly at the bottom of the timesheets. The following day, team test driver Pedro de la Rosa gave the MP4-24 its first test run at the Autódromo Internacional do Algarve. It was revealed at McLaren's headquarters in Woking, United Kingdom on 16 January 2009. The chassis was designed by Paddy Lowe, Neil Oatley, Pat Fry, Andrew Bailey and Simon Lacey with Mario Illien designing the bespoke Mercedes-Benz engine which, although also used by Force India and Brawn GP, was designed with the intention of fitting in the chassis of the MP4-24. The McLaren MP4-24 is a Formula One racing car used by McLaren-Mercedes during the 2009 Formula One season.
