Much of the development work came to an abrupt halt, but fortunately Alfieri had completed the design of two new engines that would ensure competitiveness in racing for the foreseeable future. The two twin-cam units were very similar in design with the number of cylinders the main difference. In four cylinder, 1.5 litre it was ideally suited for the voiturette series and with twice the cylinders and displacement it could power a full size Grand Prix racer.

The advanced new engines were fitted in a very conventional steel ladder frame, which was suspended all-round by solid axles and semi-elliptic leaf springs. This was sufficient for the four cylinder engine, but the power of the eight cylinder engine and large hydraulically actuated drum brakes caused the chassis to flex. Dubbed the 8CM, it was not received very well because of this lack of rigidity. It took Tazio Nuvolari to solve most of the problems and turn the 8CM into a race winner.

The legendary racer had problems with his employer, Alfa Romeo's official racing team Scuderia Ferrari, and was on the lookout for a new drive for the 1933 Belgian Grand Prix. The 'Flying Mantuan' turned to Maserati and acquired the very first 8CM, which had been returned by Raymond Sommer. After the practice for the Belgian Grand Prix, Nuvolari brought his car to the Minerva factory where he added several cross-members to increase the rigidity. The modifications made a night and day difference and the always charging Nuvolari took the lead on the first lap even though he had to start from the ballot determined grid. He went on to win the prestigious race.

Maserati were quick to make similar changes to the design for the 1934 cars. Although the additional cross-members increased the weight, the added rigidity more than made up for those extra pounds. The 1934 8CM initially weighed in well over the new minimum weight of 750 kg set for that season, but a strict diet brought the racer down to the minimum set without having to scrape the paint down to the bare metal. It proved to be insufficient to take on the Alfa Romeo, Mercedes and Auto Union teams, but the car's availability made it a popular choice for privateer racers. A further stripped down chassis was constructed in 1935 for a successful speed record run down the Autostrada.

In the following years Maserati would continue to produce racing cars for top level Grand Prix racing, but the well funded competition proved to be too strong to bring back the successes scored with the 8CM. Ventures in the highly popular voiturette class with a variety of four and six cylinder engined cars were more successful; both on the track and commercially.
