Bentley Mulliner’s Speed Six Continuation Series completes testing with Goodwood finale

The 2024 Goodwood Festival of Speed saw a host of dynamic debuts and unveils and standing out among them as a blast from the past was Bentley Mulliner’s Speed Six Continuation Series. Twelve Speed Six Continuation Series customer cars are planned to leave the factory but Bentley aims to ensure their durability with strenuous reliability tests planned with two development cars. One of the two cars, a 205bhp ‘Factory Works’ unit finished in Bedford Grey, completed eight separate runs up the famous Goodwood hill climb without any hesitation or concern. Car Zero, the main test prototype, passed an extended series of gruelling tests comprising 8,000 km of intensive mileage accumulation at Millbrook Proving Ground, multiple Vmax (top speed) test runs, 130 laps of the Goodwood Motor Circuit in a single session and suspension tests on unmetalled surfaces of a kind that would have been familiar to Bentley drivers of the 1920s. In total, Car Zero had accumulated 11,700 km of intensive test mileage which stands equivalent to 30,000 km in normal driving. With the tests complete, Bentley Mulliner commences work on the first Speed Six Continuation Series customer cars with the first deliveries scheduled in autumn. Each of the Speed Six Continuation Series cars will be trimmed and finished to its owner’s specifications from a choice of period-correct finishes and materials.
