Both cars share the same chassis , the only obvious difference between them is the higher cockpit side protection for VJM01 and the new wings . It is clear that the new VJM01[/b is an evolution of last year's Spyker VII B-spec which was the slowest car in 2007 . So Force India would probably remain the slowest car in 2008 also because you can not improve dramatically a very slow and outdated car . The only strong point will be their Ferrari engine .I am sure that the team will need a completely new car during the season to grab a point or two .
No keel design remains unchanged
