The larger-engined Bentley was first known as the 6.5 and was first shown in 1926. It was offered with a 'Standard' chassis and a 'Speed' model. The Speed Six debuted in September 1928 and was credited with being the car that most worried its rival, Rolls-Royce, because of the Bentley's power and performance and its refined ride and handling.

The Bentley 6.5-liter was one of the world's finest and most respected automobile of the 1920s, which many consider to be the original sports car. It was first offered to the public in 1921, and it quickly earned the company a reputation for outstanding quality, elegance, rapid acceleration and speed. It was such a dominant force on the racetrack that other auto manufacturers were hesitant to compete against it. During the first eight runnings of the famed le Mans 24-Hour race, Bentleys had won five times, four of which were consecutive - a record that stood until the 1960s. During the 1929 Le Mans race, Bentley Speed Sixes crossed the finish line in 1st, 2nd, 3rd and 4th place. In 1931, Rolls-Royce Ltd. became the owner of Bentley Motors, after the company declared bankruptcy.

This Bentley was originally a standard 6½-liter that was later returned to Bentley Motors soon after it was purchased, and upgraded to Speed Six specifications. It is now fitted with the more powerful Speed Six engine and correct C-Type gearbox.

In 1965, Reg Parker discovered this car just a short distance away from his home. Parker had many significant cars in his London-based collection, including Rolls-Royces, Alfa Romeos, Aston Martins, and Bentleys. He had assembled one of the most complete collection of Bentley cars ever assembled.

While in the care of Mr. Parker, this car was treated to a complete restoration. Since then, the car has won several significant class awards at concours events, and been featured in several books and publications.

In 1983, the present owner purchased this car from Parker. Since then it has been fastidiously maintained and used sparingly. The car still retains its original Sedanca Coupe body by Motor Bodies of Newcastle. This car is just one of only 13 6.5-Litres still wearing their original bodywork and the sole example to feature Motor Bodies craftsmanship.

The car has twin side-mount spares, a unique folding roof, and is finished in a black-and-green paint scheme.

In 2008, this Bugatti 6.5-Liter Sedanca Coupe was offered for sale at the Gooding & Company auction held in Pebble Beach, CA. The car was estimated to sell for $700,000 - $950,000 and offered without reserve. As the gavel fell for the third and final time, the car had been sold for $561,000, including buyer's premium.

Coachwork: Vanden Plas
 
To meet the demand for a chassis larger than his established three-liter to carry closed luxury coachwork, W.O. Bentley introduced a new 6.5-liter, six-cylinder model in 1926. Its engine was mounted on rubber pads to limit vibration, and three wheelbases were offered, enabling customers to fit 'anything from a two-seater to a hearse body.' But Bentley's sporting heritage would not be denied, and soon there was a sports derivative of the new car on the market. Known as the Speed Six, it had a higher compression ratio than the Standard Six, and two SU carburetors instead of the single Smith carburetor of the less powerful car. Out of the 544 6.5-liter Bentley's built, 171 were Speed Sixes. In 1929, Speed Sixes crossed the finish line in spectacular fashion at the 24 Hours of LeMans, scoring a 1-2-3-4 clean sweep. This example was originally owned by the Duke of Kent, and was thought to have vanished just before WWII. It was later found to have been raced extensively at historic events with a different body style.

This speed Six Bentley was originally delivered to Bertie Kensington-Moir with the standard long-distance body built by Vanden Plas. It has the spare wheel partially recessed into the tail in a similar fashion to the bobbed tail design first seen on the LeMans 4.5 Liter Bentley in 1928. The standard Bentley 6.5-Litre and the high-performance Bentley Speed Six were in production from 1926 to 1930. They were designed by W.O Bentley to offer more power. This was accomplished by adding two cylinders to the engine used in the 4.5-Liter car. The Speed Six, introduced in 1928, was the most successful racing Bentley at LeMans and at other sports car races.
Sedanca deVille
Coachwork: Mulliner
 
This Vintage Bentley is not only original, it is also the only surviving Sedanca saloon. This long chassis 6.5 Litre Bentley is the very car that was shown at the Olympia Motor Show in 1929, and it still exhibits its original color scheme. Built by H.JJ. Mulliner, the body is typical of the style of the luxurious coachwork that was often seen on 'Big' Bentleys in the period but is now very hard to find. It has spent many years in Australia, and its owner has driven the car on many European and Australian tours.
Open Two Seater Boattail
Coachwork: Park Ward & Co.
 
This is one of only eleven open Bentley Speed Sixes with its original body - a Park Ward boattail speedster with pontoon fenders. Park Ward of London started by producing bodies for the Rolls-Royce Silver Ghost and was a major supplier to Rolls-Royce and Bentley owners throughout the 1920s. Originally delivered to a Mr. Donald Hurt in 1929, this car is one of 182 Bentley Speed Sixes built between 1926 and 1930. During its 80-year life the car had one other body - a sporty two-seat design built by Abbots of Surrey, England, and fitted to it just after the war. The original body, seen here, was fitted on another 6-liter Bentley of the same period, but it has now been reunited with its original chassis. It was given a restoration, which was completed in the late 2000s.
Fixed Head Coupe
Coachwork: Gurney Nutting
 
Developing 180 horsepower and 100 mph, the Speed 6 was a sportier version of the 6.5-liter, with an inline 6.597-liter single piece steel engine block and head. Favored by British royalty, this model was Bentley's most successful racer, winning Le Mans in 1929 and 1930. This fixed head coupe, on a custom chassis by Gurney Nutting, has a Weymann-style fabric covered body over a steel and wood frame.
The Bentley 6.5 Litre was a continueation of the Litre series Walter Owen Bentley had created. The four-cylinder 4.5-liter unit used in the 4½ Litre was used for the 6½ Litre Bentley but the 6½ Litre Bentley had two extra cylinders. The Bentley stright-6 had a cast-iron block and head with an overhead camshaft having four-valves per cylinder. There were two spark-plugs per cylinder. The 100 mm bore and 140 mm stroke resulted in a displacement size of 6597. Horsepower was in the neightborhood of 180 - 200.

The design was based on the Bentley 3Litre but inspired by the Rolls-Royce Phantom I. There were a variety of chassis sizes available that ranged from 132 inches to 152.5 inches.

In 1928 Bentley introduced the Speed Six which would, in time, become the most successful Bentley racer. Woolf Barnato, Tim Birkin, and Glen Kidston drove the Speed Six to victories at the 1929 and 1930 24 Hours of Le Mans.

In total there were 363 examples of the Bentley 6½ L and 182 examples of the Speed Six.

The Bentley Company was created by Walter Owen and Henry Bentley in 1919. Within a few years they had their first 24 Hours of LeMans victory. The company prospered for a number of years before going into receivership in 1931. The company had created a total of 3033 cars and had won victories at LeMans five times.

The litre series engines began in 1919 with the four-cylinder 3-litre unit. For its day, it was very technically advanced, thanks, in part, to the technical abilities of WO Bentley. The engine had dry sump lubrication and an overhead camshaft which operated four valves per cylinder. The use of aluminum pistons was also ahead of its time. In an effort to reduce gasket leaks the entire cylinder block was cast as one piece. The displacement size was increased during the early 1920s culminating to the 6-litre Bentleys. This new model, announced in 1925, had a displacement size of nearly 6.6 liters from the new six-cylinder engine. It drew inspiration from the 3-litre units that had brought many victories to the company. During 1925 and 1926 the Six-Litre Bentley's had mild success on the racing circuit as these seasons were plagued with bad luck for Bentley. In response, Bentley began work on a performance version.

The new special model was ready by 1928 and dubbed the Bentley 6 1/2 Litre Speed Model, also known as the Speed Six. The true potential of the Speed Six was experienced during the 1929 and 1930 LeMans race where the Bentley Speed Six models dominated the race. The drivers and co-drivers who piloted the machines to victory were Woolf Barnato, Tim Birkin, and Glen Kidston.

Success at LeMans was due to many factors including expericne, knowledge, and a durable 200 horsepower engine. The company looked poised to be a strong competitor at LeMans in 1931 but financial difficulties kept them from competition.

The Bentley Company was later bought by Rolls Royce and the proud and historic racing program was discarded.
