Alfa’s 6C 2300 model was short lived compared to the 2500 model that followed. It was in produced from 1934 through 1938. In that time, the company turned out just 760 examples, with the “B” variants coming into the line in 1935.

These 2300 B variants still used the same 2.3-liter DOHC inline-six that produced 70 horsepower on this single-carburetor unit. This long-chassis Turismo model wears one-off coachwork by Pinin Farina.

The car was later on display at the 1938 International Motor Show in Berlin and then spent decades in Switzerland and later France and Italy. It is one of 81 Turismo cars built between 1936 and 1937, and it was restored in the 1990s. The estimate here is $900,000-$1,200,000. Click here for more info.

Alfa’s 6C model was around for over 25 years, debuting in 1500 form in 1927 and bowing out with double the displacement after 1954. While the handful of 6C 3000s built were mostly race cars, it was the 6C 2500 that was really the final evolution of the model.

The Super Sport variant debuted in 1939 with triple carburetors on the 2.5-liter inline-six, which was good for 110 horsepower. A few different body styles were offered on this chassis, including the Touring-penned Villa d’Este coupe, of which just 36 were built.

Delivered new in Switzerland, the car eventually made its way to Texas. It was restored in Milan, though the catalog doesn’t quite make it clear when. Sometimes in the ’80s or ’90s apparently. This car is pretty fantastic, and it has an estimate of $450,000-$550,000. Click here for more info.

Alfa 6C 1500

The 1500 variant of the Alfa Romeo 6C was the first, and it was a car that would launch a dynasty of pre- (and post)-war sporting machines. Introduced in 1927, it would be available in five forms of tune (from Normale up to Super Sport Testa Fissa) through 1929, with outputs ranging from 44 horsepower to 84.

This car is powered by an example of Vittorio Jano’s 1.5-liter inline-six that made 44 horsepower. The bodywork here isn’t original but is of the type that this car could’ve had back in the day.

Speaking of back in the day, this car was sold new in Argentina and was eventually acquired by Pur Sang – the Bugatti replica maker who split the body from the chassis. It’s been re-assembled and is ready to run. The estimate is $235,000-$280,000. Click here for more info.

The Alfa Romeo 6C 2300 was introduced in 1934 and was updated to “B” specification in 1935. That car remained in production through 1938. Different models were offered from the factory, many of which ended up with coachbuilt bodies. The 2300 B Pescara was sold from 1935 through 1938. Only 120 were produced.

This car was bodied by Worblaufen of Switzerland and was first shown at the 1938 Geneva Motor Show. The car was restored by a previous owner in 1983 and has since held up very well.

Power is from by a 2.3-liter inline-six good for 95 horsepower. This pre-war European beauty is expected to sell for between $725,000-$825,000. Click here for more info and here for more from Artcurial.

Supercharged Alfa 6C 1750

1929 Alfa Romeo 6C 1750 Supercharged Super Sport Spider

Offered by Bonhams | London, U.K. | December 7, 2019

The Alfa 6C 1500 gave way to the 6C 1750 in 1929. Displacement, obviously, increased and the straight-six engine jumped to 1,752cc. Six different series of the 1750 were produced between 1929 and 1933.

Within those six series were an array of different models. The Super Sport, which was available in both supercharged and non-supercharged form, was only available in 1929 as a “Series III” model. For 1930, it became the Gran Sport, all of which carried a supercharger. This Supercharged Super Sport made 85 horsepower when new.

This car carries coachwork from Zagato and it does not appear to have been fully restored. This 6C 1750 Series III Super Sport is one of 112 built and should bring between $1,000,000-$1,600,000. Click here for more info and here for more from this sale.

Extralusso 6C

1947 Alfa Romeo 6C 2500 Sport Cabriolet by Stabilimenti Farina

Offered by Bonhams | Paris, France | June 30, 2019

We’ve featured a pair of other Alfa Romeo 6C 2500 Sport Cabriolets – each of them different. Here is another one, with styling penned by Giovanni Michelotti while working his first gig at Stabilimenti Farina, which was founded by the brother of Pinin Farina. The body is described as “Extralusso,” which means “extra luxury.” So I guess it’s pretty nice inside.

The 6C dated to 1927, and the 2500 version of the car went on sale in 1938. It would go on hiatus during the war, and return for a brief period until 1952. This post-war example is powered by the same pre-war 2.5-liter inline-six that produced 90 horsepower in post-war Sport trim.

It is thought that only a handful of these cars were bodied by Farina, but all of them had slight differences. Only two are known to remain. It’s an attractive car in nice colors and should command between $280,000-$340,000. Click here for more info and here for more from this sale.

The Alfa Romeo 6C was new for 1925 and the 6C 2300 would be the fourth version of the model. It was introduced in 1934 at the Milan auto show and was the first version of the 6C with over two liters of engine capacity.

The engine is a 2.3-liter straight-six and in this trim it makes 95 horsepower with a top speed of 90 mph. The 2300B Pescara was built between 1934 and 1937, with 185 models produced in total (this includes non-B Pescaras as well).

This Pescara Berlinetta was bodied by Pinin Farina for the 1937 Milan show. It is thought that this body work is actually unique in its glorious Art Deco-ness. After the war, this car was used in hillclimbs before being butchered and converted into a pickup truck in 1954. Luckily, it was discovered in 1992 with a good portion of the original parts there – but the restoration, which began in 2002, required a reconstruction of the fastback section.

Today it looks wonderful. It’s a fine example of 1930s pre-war style by one of the world’s most famous design houses. It will likely sell for between $950,000-$1,700,000. Click here for more info and here for more from this sale.

ex-Scuderia Ferrari Alfa 6C 1500 SS

1930 Alfa Romeo 6C 1500 Super Sport by Zagato

Offered by Coys | Essen, Germany | March 29, 2014

The Alfa Romeo 6C 1500 was the first of Alfa’s legendary 6C/8C models. It was a lightweight, low-slung sports car – especially when compared to the big touring car it replaced. And with bodies from the likes of Zagato, their sportiness would never be questioned.

New for 1925, the 6C 1500 used a 1.5-liter straght-six and in blown Super Sport trim, this car wears a supercharger that pushes output to 76 horsepower. Top speed was 87 mph. It was more powerful than many of the 6C 1750 models that were introduced as this car’s replacement in 1929.

This 1930 model is one of the last 6C 1500s built and it was delivered new to Scuderia Ferrari in April of 1930 – Ferrari sold it three months later. It has period competition history as follows:

  • 1933 Mille Miglia – 16th, 2nd in class (with Giuseppe Mignini)
  • 1937 Mille Miglia – 10th, 1st in class (with Pasquale Contini and Salvadori)
  • 1938 Mille Miglia – 21st, 1st in class (with Felice Bellandri and Vegelli)

The car was restored in 1980 and has been in current ownership for 30 years. It is obviously eligible for the historic running of the Mille Miglia. About 3,000 6C 1500s were built but only 12 of those were supercharged Super Sports like this one. I don’t even want to guess how many came through Scuderia Ferrari. This is a big time, big money car. Read more here and see more from Coys here.

Post-War Alfa 6C 2500

1947 Alfa Romeo 6C 2500 Sport Cabriolet by Pinin Farina

Offered by Bonhams | Francorchamps, Belgium | May 25, 2013

1947 Alfa Romeo 6C 2500 Sport Cabriolet by Pinin Farina

You know what I love about this car? Its simplicity. While it has attractive coachwork by Pinin Farina, it isn’t overly extravagant and ridiculous. It’s subtle and restrained. It also looks like a big car and like a car that, if you owned it, you would want to drive.

The post-war 6C 2500 was a carryover of the model introduced by Alfa Romeo in 1938. Production restarted in 1946 after serious effort to get their ravaged factory back to operational status. As you can see, there was a restraint with post-war designs that came from a more subdued Europe that had spent too long in the throes of war. The engine was also carried over, the 2.5-liter straight six, which, in Sport trim, made 90 horsepower.

This is one of three Pinin Farina-bodied aluminium (with steel doors) Cabriolets built as a 6C 2500 Sport. It has been in the same family since 1975 and used “sparingly” as it is all-original. It’s a very wonderful car and should sell for between $280,000-$340,000. Click here for more info and here for the rest of Bonhams’ auction lineup.

Diamante-bodied Alfa 6C

1942 Alfa Romeo 6C 2500 Series III Sport by Diamante

Offered by Bonhams | Francorchamps, Belgium | May 25, 2013

1942 Alfa Romeo 6C 2500 Series III Sport by Diamante

The Alfa Romeo 6C line entered production in 1925 but the 2500 model you see here didn’t come along until the end of 1938. Production ramped up in the face of war, which would seize Europe and disrupt automotive production and design – setting both back by nearly a decade.

But this car is tastefully appointed and used Alfa’s race-bred 2.5-liter straight-six. It wasn’t some last-minute car cobbled together in a warehouse. These were wonderful, well-engineered cars. Power output was 95 horsepower in the Sport model. The cars were bodied by many famed design houses and sold to royalty the world over. Alfa managed to build a few hundred of these before war broke out, with production continuing afterward and ending in 1952.

This chassis originally sported a cabriolet body by Touring but when it was rediscovered in 1998 the body had already been replaced by this sporty roadster body by Diamante (a coachbuilder I know almost nothing about). It was acquired by the most recent owner in 2008 who had it restored further than what was carried out ten years prior. It has competed in a number of historic events and is eligible for even more. It should sell for between $490,000-$690,000. Click here for more info and here for more from this sale.
