Wally Hassan was one of the finest mechanics at Bentley, and in the 1930s he was retained by former chairman and Le Mans winner Woolf Barnato to work on his personal cars. He had Hassan build him an 8 liter Bentley single seater in order to win the record at Brooklands. This car was to become known as the Barnato-Hassan. Bill Pacey asked Barnato if Hassan could build him a 4.5 liter version, and the Pacey-Hassan was born.
This year, FIA will be paced by the most powerful safety car in the organization's history. The 585 hp Mercedes-AMG GT R has been modified to take to the track in the event of inclement weather or accidents. The most noticeable visual difference are the graphics and of course the prominent light bar on the roof. It is mounted on a carbon fiber air scoop that directs air towards the rear aerofoil for added downforce.
