The Wolseley 24/55 was a car produced only in 1925.

The 24/55 has the same 3.9 litre six cylinder engine from the Twenty. The engine still produced 55 bhp (40 kW).

The 24/55 also shared the same wheelbase as the Twenty, being 3480 mm long. The difference between them is that the 24/55 was slightly larger. The cars are 4623 mm long and 1829 mm wide.

Like the Twenty, two body styles were available. A four-door sedan and a four-door touring car.

The 24/55 disappeared without a replacement.
