1923 A new 10 was launched, as the Q Type, with coil ignition, electric starting, optional front wheel brakes and a top speed of 55mph.
1925 The 12 was replaced by the 12/35, with front wheel brakes, plate clutch and two feet extra in the wheelbase.
1926 Standard front wheel brakes were added, and the engine was bored out to 1190cc to become the P type.
1929 The engine size grew again, to 1307cc, when the car became the P2.
1930 The final Swift car was the 1930 Cadet, which was an attempt to compete with the £100 cars. This had an 850cc Coventry Climax engine and a price of £149 for the tourer and £165 for the saloon but Swift was too small to compete with the like of Ford and Morris and closed in 1931.
