Context paragraphs:
Alfa Romeo Twin Spark engine: Alfa Romeo Twin Spark (TS) technology was used for the first time in the Alfa Romeo Grand Prix car in 1914.  In the early 1960s it was used in their race cars (GTA, TZ) to enable it to achieve a higher power output from its engines.  And in the early and middle 1980s, Alfa Romeo incorporated this technology into their road cars to enhance their performance and to comply with stricter emission controls.

Alfa Romeo Tipo 512: The Alfa Romeo Tipo 512 was intended for replacement for Alfa Romeo 158 Voiturette racing car.  Designed by Wifredo Ricart as his second car for Alfa Romeo after V16-engined Alfa Romeo Tipo 162.  The car was first mid-engined Alfa Romeo model.

ALFA Grand Prix: ALFA 40/60 GP or GP (Grand Prix) was a fully working early racing car prototype made by the company now called Alfa Romeo.  Only one example was built in 1914, which was later modified in 1921.  This was creation of Giuseppe Merosi and was first Alfa Romeo DOHC engine.  It had also four valves per cylinder, 90 degree valve angle and twin spark ignition.  Usually Alfa Romeo DOHC engines are thought to be Vittorio Jano's creations but the first one was Merosi's GP car.  This kind of engine architecture was very new for the time, originating from 1912/1913 Peugeot designed by Swiss engineer Ernest Henry.  The history of this engine architecture is unclear, but other cars with dual overhead camshafts in the era were made by Sunbeam, Delage and Humber.  This 1914 GP car was intended to take part in French Grand Prix of that year, but for reasons unknown this never happened.  In 1921 Giuseppe Campari took part in the Gentlemen G.P. in Brescia with the modified GP car, but was forced to retire due to a leaking radiator.

Alfa Romeo P3: The Alfa Romeo P3, P3 monoposto or Tipo B was a classic Grand Prix car designed by Vittorio Jano, one of the Alfa Romeo 8C models.  The P3 was first genuine single-seat Grand Prix racing car and Alfa Romeo's second monoposto after Tipo A monoposto (1931).  It was based on the earlier successful Alfa Romeo P2.  Taking lessons learned from that car, Jano went back to the drawing board to design a car that could last longer race distances.  The P3 was the first genuine single seater racing car, and was powered by a supercharged eight-cylinder engine.  The car was very light for the period, weighing just over 1,500 lb (680 kg) despite using a cast iron engine block.

Alfa Romeo 6C: The Alfa Romeo 6C name was used on road, race, and sports cars produced between 1927 and 1954 by Alfa Romeo; the "6C" name refers to six cylinders of the car's straight-six engine.

Starting from 1933 there was also a 6C version with a factory Alfa body, built in Portello.  In the early 1920s Vittorio Jano got a task to create a lightweight, high performance vehicle to replace the Giuseppe Merosi designed RL and RM models.  The car was introduced in April 1925 at the Salone dell’ Automobile di Milano as the 6C 1500.  It was based on the P2 racing car, using single overhead cam 1,487 cc inline six-cylinder motor producing 44 horsepower, in the 1928 was presented the 1500 Sport which was the first Alfa Romeo road car with double overhead camshafts.

It has become historically significant as the last Alfa Romeo to have been fitted with an inline six-cylinder engine with twin overhead camshafts.  That had been the traditional Alfa Romeo engine configuration since the 1920s, but gave way to four-cylinder engines as the factory oriented its production towards more economical mass-produced car models starting in 1950.

The engine was a short-stroke version of the Alfa Romeo Giulietta's 1.3 litre engine, developed so as to enable it to compete in racing categories restricted to engines of less than one litre.  The stroke was down to 58.0 mm while the bore remained 74.0 mm .  The tubular chassis reportedly only weighed 50 kg , and the car was fitted with a fully synchronized five-speed "System Porsche" transmission.
