8. Campbell-Railton Blue Bird – United Kingdom (301 mph):
With the Brits pushing the limits, the Blue Bird was powered by a 2,300 HP 36.7 litre supercharged Rolls Royce R V12 engine in setting the record at the time. Setting the record at the Bonneville Salt Flats in September of 1935, Malcolm Campbell was first to reach the 300mph mark for land locked vehicles.
7. Thunderbolt – United Kingdom (345 mph):
Using twin Rolls Royce R-Type V12 aero engine to drive this vehicle, Captain George Eyston set the record that stood 25 years. The record was set on August 28, 1938 at the Bonneville Salt Flats, one year later World War 2 started, thus the reason for the lull in between records.
