The Bentley S3 is a 4-door luxury car produced in the years 1962-1965. The S3 was very similar to the S2, with the most noticeable external difference being the headlight layout. The interior has been redesigned. Front passengers were given separate seats and rear legroom was increased.

The base model was powered by the 6.2-liter V8 engine from the S2, which was slightly modified and mated to a 4-speed automatic transmission. The power steering has also been improved. The car had rear-wheel drive and the engine was located in front. A total of 1,629 examples were produced, including the S3 Continental. Replaced by the Bentley T1
