Motori Moderni was a Formula One engine manufacturer from 1985 through 1987. It was established by the experienced Italian engine designer Carlo Chiti. Chiti, a former Alfa Romeo Formula One chief engineer, formed Motori Moderni to make turbocharged V6 engines for Minardi, known as the Tipo 615-90. The engines were used by Minardi in Formula One from to and by AGS in . V6 Turbo 1985 Their debut was at the 1985 San Marino Grand Prix where Pierluigi Martini impressed the F1 community using the new engine to put the grossly overweight (+ compared to other turbo cars at around ) M185 19th on the grid. From all reports of that first race meeting, the only problem with the Motori Moderni was a broken fuel pump belt in practice. Martini failed to score a point in 1985 with a best finish of 8th and last in the season ending Australian Grand Prix and it was generally accepted that Martini was not yet up to F1 standard. Also, at the three fastest circuits on the calendar, the Motori Moderni powered Minardi was hopelessly outclassed. At Silverstone for the British Grand Prix, Martini was 8.054 seconds slower than Keke Rosberg's pole winning Williams-Honda (Rosberg had set the pole at an average of 160.9 mph (258.9 km/h), the fastest ever turbo lap speed). At the Österreichring in Austria he was 11.2 seconds slower than Alain Prost's McLaren TAG-Porsche, while at Monza in Italy he was 8.8 seconds slower than Ayrton Senna's Lotus-Renault. In its debut season, the Motori Moderni engine was producing approximately . This compared to the approximately of the Renault, Honda and BMW turbo engines, and the of the TAG-Porsche and Ferrari engines. 1986 Martini was replaced in 1986 as the team expanded to running two cars for the fast but crash prone Italian Andrea de Cesaris, and F1 rookie Alessandro Nannini, who showed his class by more often than not out pacing his more experienced countryman and generally was only let down by the underpowered engine and the quality of the M186. This was much to the annoyance of de Cesaris who often demanded to drive Nannini's car feeling it was better than his own and that as the team's lead driver he should get their best car. Again no points were scored with the Motori Moderni engines which were rated at approximately . This compared unfavourably to the leading
