The first steps in motorsport – it was a disaster. ALFA had nothing to back their efforts, so they copied FIAT’s solutions, as FIAT’s 6-cyl worked all the time, every time. Problem was, when ALFA got those engines and finished their vehicles, FIAT already had 8-cylinder in a straight layout, that demolished all the new ALFAs easily. ALFA had also seen a tragic event, when one of their drivers had to be packed in a bag. All the others withdrew from that race. Some of them never came back on the track. Young Enzo Ferrari was sent to negotiate with the head FIAT thinker – Vittorio Jano. Jano agreed to join ALFA immediately, and not longer than a week after, his family was already living in Milan.
He was first tasked with redesigning their P1 racer into a usable piece of machinery. Before he changed teams, he had a good project in his mind. It was an Inline 8-cyl twin cam. He made a lot of changes to it, to refine the motor, as the 1923 season revealed its issues. Instead of 2 4-cylinder blocks, he used 4 blocks of 2 cylinders each. Cast iron, much more simple and largely solid. The crankshaft of that thing required 10 bearings per cam – and it was a twin cam – so it wasn’t cheap to build, but its reliability was unmatched. Jano increased the valve angles, and put the downdraught carburetor in behind the supercharger. 2 valves per cyl it had in a DOHC layout. 134 bhp from a Roots supercharged unit. A 4-speed was installed within a sheet-steel frame. Semi-elliptic leaf front suspension was nothing new. The rear – the whole back was narrowing very low, and it was standing on springs linked to the body frame. The car body variants were those of a longer, aerodynamic rear end – and one shortened, which offered more stability in corners. The drivers could choose what to drive. It was that time, when the cloverleaf first appeared on the engine covers – and the ‚quadrifoglio’ will stay with Alfa Romeo forever.



Jano used old 6-cyl to juxtapose them with the new engines. He experimented on supercharging and it helped him refine his 8-cyl, 2-litre supercharged P2 racer. And it was a secret project, really. When shown to public, the opposition was shocked. Ascari dominated its first outing in 1924, and he won the race with avg. speed of almost 100 mph. Campari was in the lead when he pierced his tire. If not for that, Alfa Romeo would have had a one-two in their second race. The best that day was E. Ferrari behind the wheel of an Alfa R/L. The next event in the calendar was the French Grand Prix, so the stake was enormous…
It was a long race on the streets of Lyon – 810 km on public roads. All big figures were present: Delage, Fiat or Bugatti. None could counter Alfa Romeo. Their drivers were outrageously fast. Both Campari and Ascari – they had such a lead, that they delivered first position with no stress at all. Ascari set the tempo for the entire race, but his block cracked at the end, so he had to retire. The other P2 had no problem reaching the finish line in triumph and glory. The France trophy goes to Italy. Italian Grand Prix was next. It was a Monza race, where after 80 laps, P2 drivers landed on first 4 positions, with almost an hour lead over their closest rival.



3 Alfas show up at the start of the Spa race. It was the Grand Prix Europa and Ascari, Campari with Gastone Brilli-Peri, were behind the wheel. Ascari set the fastest lap, and he won at the end. Second place on the podium was for Campari in the other Alfa Romeo. Their luck ends though, and with the next event: the Montlhéry race, Ascari loses his life in a crash. He was 37 years old – and a 4 times Grand Prix winner. A tremendous loss. Left a 7 year old son, who would become a double F1 World Champion, before he also dies a 36 years old – and as well on the 26th day of the month. Just like his father did. After the old Ascari is out – the whole team gives up and Delage comes to finish first.
Monza was the last race that year and Italians sent 3 drivers again. Pete DePaolo takes Ascari’s place. The American had just managed to come first at the Indy500, driving a Duesenberg. It was a good asset, but no match for the Alfa Romeo of Brilli-Peri. Well, he was the best that time, alright… He came first – 20 minutes before Campari in the second Alfa – who was 10 minutes in front of the third Bugatti. Alfa was higher in ranks than Duesenberg and won the series in the end. It was the first edition of the World Championships – which later would evolve into what we know now as F1 racing. Starting that year – all road going Alfa models will have their logo embraced in laurels. But the season ends with huge changes in race regulations. Even those didn’t end Alfa Corse domination. P2s would win 14 times in that decade – 14 times Great Grand Prix wins, and other major events like Targa Florio. And Jano didn’t really make any revolutionary change to their setup. The P1 failed race car lost good 100 kg, and in the guise of P2, it became a rival not to be treated lightly. One only Bugatti Type 35 could match in any way.



The P2 was the first Jano project – first of all his successful Alfa racers. Not only Grand Prix contenders, but also road-going sports cars. It was the best race car of its times. Alfa would be the fastest on every European race track, and its domination would end only in the ’50s – after they’ve managed to win F1 twice. P2 is the beginning of that beautiful story, and it sets the underpinnings for their future wins. A milestone in the world of motorsport. Jano Alfas were like art – and so was the P2. Just look at the engines of his architecture. They could rev to 6.5k RPM without a single problem ONE HUNDRED YEARS AGO! The engineers made them have specially designed valve springs, to limit the engine revolutions – without them, they could easily reach 9k.
One of the oldest car manufacturers Alfa is, but its legend starts with the P2 in the ’20s. 6 examples of that car will we built in that period, and at least two are running today. One sits in the Alfa Romeo museum – fully functional, race ready and in the Grand Prix winning configuration. Every inch is identical to original. The F1 World Champion, the 3 times Le Mans triumphant, Phil Hill had a chance to drive it in 1981, and he was impressed with the quality of the vehicle he’s been given. The other known example was the one Achille Varzi took to a Targa Florio win – flat grille variant. It had a spare tire mounted at the rear – and it has it now. You can witness it in Torino museum.
