In 1950, Lancia introduced the world's first production V6 engine in the Lancia Aurelia. The engine was the work of Francesco De Virgilio and was developed to solve the vibration problems Lancia had experienced with its V4 engines. This was achieved by setting the vee angle to 60 degrees. It remained in production through 1970. Lancia used V6 engines in road and sports cars, the D20 had a 60 degree quad cam V6 2962 cc engine (217 bhp) and the D24 3300 cc V6 engine

Aurelia

The first-generation Aurelia engines were produced from 1950 through 1967.

1800

The 1.8 L (1754 cc) 1800 was the first V6. Bore was 70 mm and stroke was 76 mm.

• 1950 Lancia Aurelia

2000

The engine was expanded to 2.0 L (1991 cc) for 1951's B21 Aurelia. Bore was 72 mm and stroke was 81.5 mm.

• 1951-1952 Lancia Aurelia

2300

A 2.3 L (2266 cc) version was also produced.

2500

The largest of the original Aurelia engines was the 2.5 L (2451 cc) 2500 introduced in 1953. It was still undersquare at 78 mm bore and 85.5 mm stroke.

• 1953-1957 Lancia Aurelia

Flaminia

The engine's severe undersquare design was addressed for the 1957 Flaminia version. This lasted in production through 1970.

2500

The new 2.5 L engine displaced 2458 cc from a much less undersquare 80 mm bore and 82 mm stroke.

• 1957-1970 Lancia Flaminia

2800

The final version was the 2.8 L (2775 cc) engine. Bore was now 85 mm and stroke remained at 82 mm as in the 2500.

• 1957-1970 Lancia Flaminia

Later V6-engined Lancias

Later Lancias were powered by V6 engines designed by other manufacturers, with the Ferrari Dino V6 powering the Stratos and the Alfa Romeo Busso V6powering versions of the Thema, Kappa and Thesis.
