The cars will take pride of place on the Friday of the three-day festival of premium motoring, which takes place from 3-5 September at Syon Park in west London.
The day has been named the British Supercar Show, and will feature a parade of modern and classic cars and motorcycles around the perimeter roads of Salon Privé’s venue, Syon Park in west London.
The event also includes the Chubb Insurance Concours d’Elegance (on Wednesday), Boodles Ladies’ Day and Salon Privé Sale (on Thursday) and a Royal College of Art ‘Concours of the Future’ design exhibition (also on Thursday). The EFG art and memorabilia fair and luxury retail village will be open over all three days.
Seventy classics will vie for the title of 'Best of Show' in the Concours d’Elégance.
Among the contenders will be a 1953 Delahaye 235MS coupé. The only example of the car to feature Chapron coachwork, it hasn't been seen in public for more than two decades and is entered in the 'Dramatic Coachwork' class at Salon Privé.
Another Concours exhibit is a 1931 Hispano-Suiza J12. Entered in the ‘Fit for a King’ category, which showcases cars from around the world with head of state or royal provenance, this car was originally created for the Vice President of Hispano-Suiza, Prince Charles Casimir Poniatowski.
A collection of road-going classic cars will go under the hammer at the Salon Privé Sale. The cars on sale include a rare 1971 Ferrari 365GTS/4 Daytona Spyder, estimated at between £1.75 and £2.25 million.
Some special British models also feature, most notably a 1931 Bentley 4.5-Litre Blower. The example is number 25, the final car in the first batch of just 50 produced and its price is estimated at between £2.2-2.5m.
An Aston Martin DB6 Mk2 Volante, one of only 38 produced and equipped with the preferred manual gearbox instead of the more common automatic transmission, is expected to go for between £820,000-920,000.
