Time to Gush: Even among the proverbial greats, very few cars embody beauty, exclusivity, and racing success. How all of this comes to be in the 2900-A is a tall story—a matter of the factory changing out fashion for competition, and then changing out competition for capitalism. So, before we get started, let me state that this is one of the greatest cars featured in this collection, and probably one of the greatest yet rolling around planet earth.
Fashion First: Back in 1936, Alfa Romeo drafted a smart roadster for the Paris Auto Show. That design is what you see in the illustration, a well proportioned roadster with lots of fine details like a mix of louvres and vents on the long bonnet, a single panel sweep down across the flank, smooth skirts integrated with the running gear tucked closely against the body, and a clean integrated spare compartment at the rear. This configuration, executed by the Alfa Romeo factory, is derived from the smaller capacity Touring Spyders that preceded it, and is of course much closer to the immortal 2900-B Touring Spyder produced the following year.
But between the 2900-A and 2900-B, the former is rarer, with only a handful built in 1936. And in some sense the 'A' is more of a pure racer in that all variants of the 2900-A were intended for racing. As it turned out, the Paris Motor Show was just a quick stop for the 2900-A Spyders—just those three that were, as was later pieced together, intended for the Mille Miglia.
Competition Second: After Paris, Alfa Romeo stripped off the coachwork, fitting a typically tight sports-racing body to the frame and a set of cycle fenders to the wheels. The cars were then turned out to three driver-mechanic teams for the 1936 Mille Miglia—these being Count Antonio Brivio with mechanic Carlo Ongaro, Nino Farina with mechanic Giuseppe Meazza, and Carlo Pintacuda with mechanic Aldo Stefani. These three cars with these three pairs finished the race in this order, Mille Miglia specialist Pintacuda managing third place in spite of making repairs necessitated by a faulty carburetor. This car, chassis #412003, was the number two finisher, with Nino Farina at the wheel.
For the 1937 Mille Miglia, these three cars returned. This time, Carlo Pintacuda claimed victory alongside mechanic Paride Mambelli, while Farina and Meazza again managed second place overall in this car. Farina, who will later become the first Formula 1 World Champion, had been bested twice, although the Mille Miglia was a certain forte for those who won, (in particular Pintacuda, for whom it was a zenith). The teammates, however, formed a famous caravan to the finish of the 1937 race.
After pummeling every existing record through the early stages of the 1937 race, (and in spite of the fact that it was run in a deluge), Carlo Pintacuda lost his headlights heading into the evening. Pintacuda slowed until Farina caught up with him, and Farina then paced Pintacuda for the remainder of the race, providing enough light to see Pintacuda to the victory he deserved.
Sales Third: By 1937, the 2900-B was in the works. A proportionately high number of the B-series cars would be made, most of them intended for road use with heftier custom bodies by Touring and Pinin Farina, along with a less aggressively tuned motor. But, Alfa still had the three Paris show car bodies, and had plenty of demand to sell those cars the public had seen a little more than a year previously. So, the three 2900-A Mille Miglia cars were re-bodied in their original skins and sold to the public, and probably without an explanation about what they'd been doing lately.
The sale in 1937 sticks the model year to the car, as it was common practice to date a classic in the year it was sold, rather than the year it was built. Disagreeable, but that's the way it worked; just ask the Duesenberg people.
As of writing, all three Mille Miglia Spyders have been restored to Paris Motor Show form. All three can be seen together in the Victory by Design series Alfa Romeo special, although this example currently resides in Philadelphia's renowned Simeone Collection.
Technology: Sweeping the top spots at back-to-back Mille Miglia was no fluke, for these A-series cars represented the pinnacle of the 8C Alfa in endurance racing. The motor, Vittorio Jano's 32-valve, dual overhead cam, twin supercharged straight 8-cylinder, is producing upwards of 220 horsepower at 5,000 rpm. Comprising two of his short 4-cylinder blocks joined together with a common crank, the motor is perfectly balanced, which is quite important considering the immense torque a straight 8-cylinder produces. A well built straight 8-cylinder might have been standard fare at Packard, for instance, but such a motor was never expected to do much past 2,000 rpm.
Here we have a high revving, all alloy, supercharged motor. It's shape is long, but its mass is manageable at just 2,905cc. The 8 cylinders keep a typical 2-4-2 configuration, but the fact that the unit is really two conjoined blocks means there is no torsional strain placed on the motor. What might typically happen in a powerful straight 8-cylinder is the shaft be spun with so much torque that it begins to exert stress on the valvetrain. This can throw the timing and, ultimately, toast the motor. Jano's solution: Get the power of a straight 8-cylinder, but balance it perfectly to avoid such issues.
Fin: The engineering involved in the 8C 2900 motor was costly. So, not surprisingly, the Italian government paid for much of it. A racing version of the 2900-B followed for 1938, with Clemente Biondetti winning the Mille Miglia that year, (just ahead of another hard charging Pintacuda drive). An amazing streamlined Le Mans Berlinetta was built as well, perhaps the highest evolution of the car, and certainly the fastest.
However, the 2900-A Mille Miglia was the most successful. And, thanks to its Paris Motor Show debut, it was also among the most glamorous. For a single car to spearhead greatness of both the competitive and fashionable variety is quite remarkable, and no other great 8C Alfa did both to such a high degree.
