McLaren reveal MP4-23 in Germany

McLaren on Monday launched its 2008 contender, the MP4-23, at the Mercedes-Benz museum in Stuttgart.

The event, attended by F1 chief executive Bernie Ecclestone, coincided with the twenty-third birthday of Lewis Hamilton, the rookie Briton who in 2007 finished runner-up to world champion Kimi Raikkonen for the drivers' title.

It also emerged that, contrary to the official entry list released recently by the FIA, Hamilton will wear the number 23 – not 22 as published – on his silver single seater, which boasts a visibly straighter nose than its predecessor.

Hamilton will test the MP4-23 for the first time at an exclusive test session at Jerez on Thursday, after new Finnish teammate Heikki Kovalainen and test driver Pedro de la Rosa debut it at the same Spanish circuit a day earlier.
