Daimler Regency - Daimler One-O-Four DF310

Daimler One-O-Four DF310

Announced in October 1955the 3½-litre engine was given a new cylinder head and compression ratio of 7.6:1 generating almost 30% more power (137 bhp (102 kW; 139 PS) @ 4,400 rpm) to push the same 2-tonne Mk II to 104 m.p.h. With upgraded brakes and interior, branded firmly at its tail with a bulky fluted boss bearing a large D in the centre of its back bumper it was advertised as the 100 m.p.h. Daimler One-O-Four. Named because a prototype reached 104 m.p.h. during testing when there were no open-road speed limits. During 1956 a Borg-Warner fully automatic gearbox became available. Seventeen chassis numbers were used by this model and another forty-nine for the corresponding Lady's Model. The special lady's items in the Lady's Model inspired by Lady Docker became optional extras the following year.
