Looks like Aston Martin Racing will be jumping back into international motor sport racing in 2005 with their vamped up DBR9. This car is awesome! 6.0 liter, V12 engine sounds exciting to drive!Here are some pictures of Aston Martin's DBR9 on the track: http://www.astonmartinracing.com/gallery.htm
I doubt Aston will be entering F1 though. It seems Lotus remains the only really successful British car manufacturer to have entered F1. Jaguar's embarassing performance and recent departure from F1 haven't helped any. Seems British F1 fans can only count on non-manufacturer teams like Williams BMW & B.A.R. Honda. Well at least Cosworth were making decent F1 engines.
