Bugatti Type 35

Overview

The Type 35 is the reason a horseshoe radiator and cast wheels count as Bugatti signatures at all. Ettore Bugatti unveiled it at the 1924 French Grand Prix at Lyon with five cars entered, and the debut was a disaster: badly vulcanised Dunlop tyres, not the engine, cost the Type 35 the race. It didn't matter for long. Underneath sat a 1,991cc straight-eight with three valves per cylinder and a crankshaft running on five roller and ball bearings, a level of finish nobody else in racing was building at the time, in a chassis that weighed around 750kg dry and rode on the first cast-aluminium wheels ever fitted to a car. Bugatti sold the Type 35 to anyone with the money, works team and privateer alike, and by 1926 it had done enough winning to take the AIACR World Manufacturers' Championship: 351 races won and 47 records set in the two seasons before. Between 1925 and 1929 it won the Targa Florio five years running. Across roughly 340 cars and five factory variants, the Type 35 turned a small Alsatian workshop into the standard other Grand Prix manufacturers were racing against.

Blue-chip and effectively rarity-capped: fewer than 350 factory Type 35s were built across all five variants, and long-term institutional and private ownership keeps genuine cars off the market for years at a stretch. Documented, matching-numbers examples with traceable competition history command the highest prices, the record sale is a multiple Grand Prix-winning 1929 35B at $5.615 million in 2021, while cars with replacement engines or incomplete history trade well below the band. Recent sales suggest values have held steady rather than climbed sharply.

Callout
Five consecutive Targa Florio wins, 1925 through 1929
What to watch for
Start with the paperwork, because on a Type 35 it matters more than the paint. A century of racing, rebuilding and parts-swapping means many genuine chassis no longer carry their original engine, and coachwork has sometimes been replaced entirely; the Bugatti Trust's archive and marque historians can trace a chassis number back to its factory build sheet, and that research is worth doing before money changes hands, not after. Decide which variant you actually want before you shop: an unsupercharged 35 or 35A is the more usable, more forgiving car, while a 35C or 35B brings real performance and a real maintenance step up, since the supercharger needs a specialist who understands Roots blowers on 1920s Bugatti engines, not a generalist. Check the front axle and its through-spring mounting for cracks, inspect the cast wheels for corrosion and casting flaws rather than just cosmetic condition, and confirm the crankshaft's roller and ball bearings have been properly serviced rather than merely run. Cable-operated drum brakes were adequate for 1920s racing and are not adequate for modern traffic; budget time to learn the car's limits before trusting it in company. A continuation or replica, several respected builders make good ones, is a legitimate way to drive the experience without the seven-figure risk.

The Story

Driving character

Everything about the Type 35 is calibrated for one person paying total attention. The straight-eight fires with a hard, metallic bark through the exposed exhaust, nothing like the burble of a contemporary road car, and it wants to rev: the unsupercharged cars pull cleanly toward 5,500rpm, while the supercharged 35B and 35C build boost with a whine underneath the exhaust note and hit harder in the midrange. The four-speed gearbox uses a right-hand external lever outside the cockpit, worked with a deliberate, mechanical action that rewards a firm hand and punishes hesitation. Steering is direct and heavy at low speed, then alive the moment the car is moving, helped by the lightweight hollow front axle and cast wheels that keep unsprung weight down. There is no synchromesh and no assistance anywhere, and the cable-operated drum brakes require real forward planning. At speed on a fast circuit the whole car comes alive in a way period road tests still describe accurately: light, direct and utterly unforgiving of a lazy driver. It is, by any honest measure, still one of the great steering wheels in pre-war motoring.

Design

The Type 35's shape did more to define what a Bugatti looks like than any car since. The horseshoe radiator existed on earlier Bugattis, but the Type 35 widened it and gave it a flat bottom for the first time, the version that became the permanent marque signature, later carried through the Royale and the Type 57 and still used on Bugattis built today. The cast-aluminium wheels, eight flat spokes, an integral brake drum and a detachable rim, are usually credited as the first alloy wheels fitted to a production car, developed specifically to cut unsprung weight and improve how the suspension responded over rough roads. Underneath, the hollow forged front axle weighed around 10kg yet rarely broke, a piece of lightweight engineering rivals struggled to match. The tapered "Bordino tail" at the rear, named for its resemblance to a Fiat driven by Pietro Bordino, gives the car its unmistakable profile from behind. None of it was decoration for its own sake: every visible design choice on the Type 35, the wheels, the axle, the pointed tail, existed to save weight or cut drag, and the result happened to be one of the best-looking racing cars ever built.

Motorsport pedigree

Few cars have a competition record like this one. The Type 35 took the 1926 AIACR World Manufacturers' Championship on the back of 351 race wins and 47 records set across the two preceding seasons, and it won the Targa Florio five years running, 1925 through 1929, against factory teams from Alfa Romeo, Mercedes-Benz and Delage. A supercharged 35B driven by William Grover-Williams won the first Monaco Grand Prix ever held, in 1929. The driver roster reads like a roll call of the era's best: Louis Chiron, Tazio Nuvolari, Albert Divo, Bartolomeo "Meo" Costantini, and two of the period's most accomplished female racers, Elisabeth Junek and Helle Nice, both of whom raced Type 35s at the top level. Junek's 1928 Targa Florio, where she led the field for long stretches before finishing fifth, remains one of the standout drives of the pre-war era. The car's toughest early rival was Vittorio Jano's Alfa Romeo P2, which beat the Type 35 on its 1924 debut and took the first-ever Grand Prix World Championship in 1925; Delage's short-lived but dominant 15-S-8 was the other serious threat later in the decade.

In culture

The Type 35's cultural footprint runs through design and motorsport history rather than mainstream film or music, and that is arguably a bigger legacy. The horseshoe grille and cast wheel it popularised became the visual language every subsequent Bugatti has used to signal what it is, right through to the Chiron and Divo; Bugatti's own marketing still calls the Type 35 the forefather of its modern hypercars. Ettore Bugatti's own description of it, as the founding father of a family of "pure-blooded racehorses from Molsheim," is the line every Bugatti historian eventually quotes, and it set the template for how the marque talks about itself a century later. Within the collector and vintage-racing world the Type 35 is close to a religious object: it anchors the pre-war class at events like the Mille Miglia retrospective and Goodwood, and its shape gets reproduced constantly, in scale models, in continuation cars from builders like Pur Sang, and in tribute liveries on modern Bugattis. It is less a poster car for people who never got to drive one than a working reference point for what a Grand Prix car was supposed to be before wings and slicks changed the sport.

Owning One

Why collectors want it

A Type 35 is the cleanest way into the top tier of pre-war competition ownership: a genuine, factory-built Grand Prix car that actually won races, from a marque whose engineering reputation still rests substantially on what this car did between 1924 and 1930. The five-variant family gives buyers a real choice of era and character rather than one fixed spec. The unsupercharged Type 35 and 35A carry the purest version of Ettore Bugatti's philosophy, light weight and mechanical elegance over raw output, while the supercharged 35C and 35B add the Roots blower that eventually won Bugatti the 1929 Monaco Grand Prix. All of them share the chassis, the alloy wheels and the racing pedigree that make this the car serious pre-war collectors measure everything else against. The market reflects that: documented, matching-numbers examples with traceable competition history sit at the top of the pre-war hierarchy, while cars with replacement engines or incomplete paperwork, still common after a century of hard racing and rebuilding, trade for meaningfully less. Fewer than 350 were built across all variants, and a century of attrition has thinned that further, so buying one is as much an exercise in provenance research as it is in car shopping.

Which one to look for

The hierarchy runs roughly by scarcity and power. The original Type 35 (96 built, unsupercharged, 1,991cc) is the purest expression of the design and the one every later variant modified. The 35A, nicknamed "Tecla" by the public as a dig at its simplified crank bearings and coil ignition, was the affordable road-biased version and the most numerous at around 139 built; it is also the easiest way into genuine Type 35 ownership. The 35T, built in just 13 examples for the 1926 Targa Florio, used the longer-stroke 2,262cc block to compensate for staying unsupercharged under 2-litre Grand Prix rules. The 35C introduced the Roots supercharger to the 1,991cc engine around 1926, roughly 45 to 50 built depending on the source, and the 35B, final and rarest of the supercharged cars at roughly 37 to 45 built, combined the supercharger with the larger 2,262cc block for the most power of any factory Type 35. A 35B won the inaugural 1929 Monaco Grand Prix.

Type 35 · 1924-1930

The debut Grand Prix design and the version every later variant modified: unsupercharged 1,991cc straight-eight, five-bearing crankshaft, cast-aluminium wheels and the hollow front axle. The purest expression of the car as Ettore Bugatti first built it.

Type 35A · 1925-1930

The cost-reduced, road-biased version, nicknamed "Tecla" by the public after a maker of imitation jewellery. Simplified plain crank bearings, smaller valves and coil ignition in place of the magneto, usually delivered on wire wheels rather than cast alloy.

Type 35B · 1927-1930

The final and most powerful factory variant, combining the 2,262cc long-stroke block with the Roots supercharger. A 35B driven by William Grover-Williams won the inaugural 1929 Monaco Grand Prix.

Type 35C · 1926-1928

The first supercharged Type 35, adding a Roots-type blower to the original 1,991cc block. Won on its competition debut and remained the more dependable of the two supercharged variants through the late 1920s.

Type 35T · 1926

Built specifically for the 1926 Targa Florio. Unsupercharged like the original 35 but enlarged to a 2,262cc long-stroke block to make up for the power lost by staying under the 2-litre Grand Prix supercharger-class limit.

What owning one is like

Owning a genuine Type 35 means owning a hundred-year-old racing car that was built to win one afternoon, not to last a century, and it shows in specific places. The roller and ball main bearings in the crankshaft are a sophisticated design for 1924 but demand a specialist rebuild; get it wrong and the engine will tell you quickly. The hollow front axle and its through-spring mounting, a Bugatti trademark, should be checked for cracks at every service, since it carries real structural load in a very light package. Cast wheels can develop corrosion inside the casting that isn't visible from outside, and a cracked wheel on a car this light and this fast is not a minor issue. Cable-operated drum brakes, fine for 1920s racing, need more stopping distance and more anticipation than anyone raised on disc brakes expects, and they reward regular adjustment rather than being left alone. None of this makes the car fragile exactly, Type 35s have survived a century of hard use, but it does mean every system was designed for a mechanic who understood it intimately, and modern ownership works best when that relationship gets rebuilt.

Upkeep & parts

Parts support for a Type 35 is nothing like a post-war car's aftermarket, but it is better than the car's age suggests. The Bugatti Owners' Club in the UK, Club Bugatti France, and the American Bugatti Club between them hold decades of technical knowledge, chassis histories and specialist contacts, and the Bugatti Trust in Gloucestershire maintains an archive that can help verify a car's factory build record. Specialist restorers who work exclusively on pre-war Bugattis, several in the UK, France and the US, understand the roller-bearing crankshaft, the Roots supercharger on 35B and 35C engines, and the correct period castings for the wheels and axle; this is not a car to hand to a general classic-car shop. Budget for specialist labour rather than parts cost alone: an original casting or a correctly machined bearing set is available, but the work to fit it properly is where the real money goes. Because so many surviving chassis have non-original engines or replacement bodywork somewhere in their history, a pre-purchase inspection from someone who has personally handled multiple Type 35s, not just Bugattis generally, is worth more than any warranty could be.
