1929 Bugatti Type 46

Bridging the gap between the opulent Royale and 3-litre Type 44, the Type 46 was Bugatti’s standard luxury model. It was first launched at the 1929 Paris Motor Show and production began in the same year.

A large, one piece engine was the main feature of the Type 46. Its casting contained everything from the combustion chambers down to the main crankshaft bearings, including the cylinder walls. This setup eliminated the need for head studs and therefore the engine could be very narrow and perfectly rectangular. The flywheel was flexibly mounted to reduce vibrations in the cabin. A five-jet Smith-Bariquand carburetor was fitted.

Chassis arrangements were similar to the Type 41, having three speed gearbox in unit with the rear axle. Rudge wire wheels were fitted and the spectacular cast aluminum type as seen the Royale were eventually offered as an option. Braking was handled by large diameter drums.

Main competition for the Type 46 came from Delage’s D8, which sold in much greater numbers, but with less performance and at half the price.

Eventually , a supercharged version of the Type 46 was offered known as the 46S. The model was completely replaced by the Type 50, with its twin-overhead cam design which was a copy of the American Miller unit.

Even though Bugatti was known for its noisy race cars, the luxurious Type 46 was a successful project that sold over 460 units.

Body Styles for the Type 46 were diverse, but many used the same radiator and hood that came provided. One of the most distinct and dramatic bodies fitted to the Type 46 was the Semi-Profilee which used a raked windscreen and sweeping two tone paint job to great effect. The theme was continued on the Type 50 Coupe Profile which featured a completely sloping fastback rear end.

Auction Sales History

1929 Bugatti Type 46

1930 Bugatti Type 46 Coupé Profilée Recreation 46208 – sold for $1,017,500 The present owner opted to have the drab sedan coachwork replaced with a faithful recreation of the “Superprofile” coupe penned by Jean Bugatti, which some argue is the finest of all of his designs. The coachwork was produced by Mr. Ken Haywood of New South Wales, Australia, who has been responsible for many award-winning cars. This photo-documented restoration and coachbuilding effort is regarded as one of his finest results. Auction Source: Amelia Island 2012 by RM Auctions

1929 Bugatti Type 46

1930 Bugatti T46 Freestone & Webb Sports Saloon 46533 – did not sell for €487,200

An exceptional, older restoration with original English coachwork. One of only about 450 examples built and few survivors. A smaller “companion” model to the T41 Royale. One of the most elegant T46s in existence. Formerly in the Dr. Peter Williamson Collection.

A fabulous older restoration, it notably features interior appointments that are far richer in contrast to its French-bodied T46 counterparts. It is finished in green with tan upholstery, a particularly attractive colour combination that highlights the car’s attractive overall proportions. With known ownership history from new, this T46 “Petit Royale” in short represents an unparalleled opportunity to acquire an exceptional example of one of Bugatti’s most influential designs, complete with its original and elegant, yet sporting, Freestone & Webb custom coachwork.

1929 Bugatti Type 46

1930 Bugatti Type 46 Veth & Zoon Faux Cabriolet 46293 – sold for €632,500

This supremely elegant car is bodied in the popular two-door Faux Cabriolet style of many original Type 46s and is finished entirely in black with contrasting beige mohair hood and nickel plated side mouldings, emphasising the design’s long horizontal lines. The interior is upholstered in brown leather with a crocodile skin pattern, typical of the Art Deco period, which perfectly complements the original inlaid wood door cappings.

Chassis number ‘46293’ has covered only some 300 miles (approximately 480 kilometres) since the completion of its restoration and is presented in excellent condition throughout. Right-hand drive, like most quality French cars of the period, it represents a rare opportunity to acquire a unique, coachbuilt Type 46 exemplifying the crème de la crème of Bugatti touring cars, being one of only some 60 surviving Type 46s and certainly the best example to come to the market in recent years.

1930 Bugatti Type 46 Figoni Cabriolet 46331 – sold for €333,500

46331 was delivered as a chassis in 17th May 1930 to Garage Mondan & Wilson in Paris for its first owner, Parisian Georges Combe, who clearly recognised its outstanding specification. He was to commission two-door four-seat coachwork by Figoni – the design and craftsmanship from this carrosserie-par-excellence complementing the genius of Bugatti. Combe was to drive his elegant new car actively in the metropolis and on family trips to the Pyrenees, retaining it in regular use until 1939 when it was dismantled and hidden away during hostilities. In 1948 the car emerged from store, was re-assembled and a special estate car body was fitted (see photo) to enable 46331 to take part in the 1951 Alger-Le Cap Rallye – many other modifications being carried out at the same time, all recorded on file. A change in circumstances saw that 46331 did not suffer the indignity of participating in that event. Combe retained the car until the 1960’s, its new owner then embarking on restoring it to original condition and specification, having acquired the Figoni body from Combe’s store.

46331 found a still better home in 1996 when it was acquired by Bugatti aficionado Lord Raglan and once again the car was to be the subject of a well documented restoration using respected marque specialists including Ivan Dutton and John Merryfield amongst many others. Prospective buyers are advised to inspect the comprehensive file to appreciate fully the extent of the restoration and Lord Raglan’s attention to fine detail. She is now presented in very good condition overall and in full working order have passed an MoT road worthiness test last October.
