The 2003 Bentley Speed 8 Technical Story | Part Two

The testing programme has proceeded apace. The autumn was spent doing extensive tyre testing, benchmarking the new Michelin tyres and determining how best to exploit their performance. These tests were conducted with a 2002-specification EXP Speed 8. Early in the New Year, the first of the 2003 Speed 8s was shaken down successfully at Snetterton before heading off to the circuits of Europe for an extensive test programme prior to Sebring.

Bentley Team Director John Wickham commented: ‘The new car clearly has great potential, the drivers are very happy with the progress we are making, particularly its aerodynamic balance. As with all Bentleys we have run in the last two seasons, reliability appears to have been ‘designed in’. It’s early days but so far we have had no reliability issues with the car whatsoever.’

Andy Pope, speaking for Michelin, said: ‘The first few weeks of our association with Bentley have been extremely encouraging. We have not recently made tyres in the sizes dictated by the LM GTP class, but we appear to have found our feet very quickly and are able to supply Team Bentley with tyres that are quick, consistent and durable.’
