When the war concluded, Delage moved away from small cars and made its reputation with larger cars. First up was the CO, with a 4,524 cc (276.1 cu in) (80 by 150 mm (3.1 by 5.9 in)) fixed-head side valve six producing 20 hp. The CO plans had been drawn up during the conflict; this was the first passenger car with front brakes. It was joined by the DO with a 3-liter four.

The 1920s were really the first "Golden Age" of Delage. The most famous were the DE and DI: 4 cylinders of about 2 liters and 11 hp. Delage also attempted to compete with Hispano-Suiza, with the GL of 30hp and 5954 cc, with some success. After that came a new generation of six-cylinder cars, like the MD (3174 cc) and DR (2516 cc), the best-selling vehicle in the history of the brand, designed by engineer Gaultier.

Both the CO and DO were replaced in 1922. The CO became the CO2, which changed to an overhead valve twin-plug head, producing 88hp (66 kW; 89 PS), while the DO was supplanted by the DE with a 2,117 cc (129.2 cu in) (72 by 130 mm (2.8 by 5.1 in)) side valve four and, unusual in a production car even in this era, four-wheel brakes. The CO2 completed the Paris-Nice run in 16 hours, an average of 67 km/h (42 mph). Only some 300 (including Grand Sport models) were produced.

The next year, the new 14hp (10 kW; 14 PS) DI also switched to OHV with a 2,121 cc (129.4 cu in) (75 by 120 mm (3.0 by 4.7 in)) four, fitted with magneto ignition and thermosyphon cooling; all had four-speed gearboxes and Zenith carburetters. At the other end of the scale, the GL (Grand Luxe), also known as the 40/50, replaced the CO2, being fitted with a magneto-fired 5,344 cc (326.1 cu in) (90 by 140 mm (3.5 by 5.5 in)) overhead cam six.

The 1924 and 1925 DIS, with a 117 in (3,000 mm) wheelbase, switched from Rolls-Royce-type locking wheel hubs to Rudge knock-ons, better cam, and bigger valves, while the 1925 and 1926 DISS on the same wheelbase. Some of the DISes were bodied by Kelsch. The DIS became the Series 6 in 1927, switching to coil ignition and water pump.

In 1926, Delage introduced the DM, with a 3,182 cc (194.2 cu in) (75 by 120 mm (3.0 by 4.7 in)) six, which made it emblematic of the era for the marque. The high-performance DMS had hotter cam, twin valve springs, and other improvements. In addition, Delage produced over 13,000 four-cylinder cars in the DO, DE and DI series during the 1920s, as well as just 1,540 six-cylinder CO models, followed by the DM-DR models of 1926, the last of which were the DMN, of which just 897 examples were produced.

A DR, with a choice of 2.2- and 2.5-liter sidevalve engines, also briefly appeared.
