This is one of the cars that took part in the 12 lap race for the Richard Seaman Historic Trophy at the VSCC race meeting at Donington Park in May 2001.
It's the 1936 Maserati 6CM of Roger Lucas. Grand Prix racing in the 1930s was dominated by the German teams of Mercedes-Benz and Auto Union, and to a lesser extent the Italian Alfa Romeo team. Smaller manufacturers like Maserati built their cars for the Voiturette (or 'small car') class which was for cars with a maximum capacity of 1½ litres. The 4-cylinder Maserati 4CM introduced in 1932 had considerable success, but when these cars started to be outclassed by the British ERA cars Maserati produced the 6CM with a 6-cylinder 1½ litre supercharged engine which then became the car to beat.
