Heavily revised BMW spotted in Barca

(GMM) After the initial four races of the season, BMW-Sauber's was the most visibly changed car in the Barcelona garages.

The German squad had a dire start to the 2009 championship, and like most teams has prepared a major upgrade for the Spanish grand prix.

The revised F1.09 features radical treatment on the main element of the rear wing, and a notably straightened and raised nose.

Additionally, speculation proved correct that the team would drop the 'Active Hybrid' rear wing signage now that the cars no longer feature KERS systems.

The rearward-facing element of the rear wing now reads: 'Connect'.

On the rear-wing endplates of the Brawn car, meanwhile, is advertising for the forthcoming 'Terminator Salvation' film.
