The A99 Westminster appeared in 1959 with new
Pinin Farina-designed bodywork. Pininfarina had also re-styled Austin's compact
A40 and mid-sized
A55 Cambridge ranges the year before. A very similarly styled bodyshell was also used for the
Peugeot 404. It appears that this design, which firstly influenced the Austin and then the Peugeot, was based on the
Lancia Flaminia, also designed by
Battista Farina earlier. Under the bonnet was the 2.9 L (2912 cc) C-Series straight-6 engine with twin
SU carburettors from the
Austin-Healey 3000. This engine produced 103 hp (77 kW) in Westminster tune. A three-speed all-synchromesh
manual gearbox with a
Borg-Warner overdrive unit was fitted as standard, or a
Borg-Warner automatic transmission as an option. Power-assisted Lockheed brakes with
discs on the front wheels were also new. An A99 saloon with automatic transmission was tested by the British magazine
The Motor in 1960 and they recorded a top speed of , acceleration from 0– in 17.9 seconds and a fuel consumption of . The test car cost £1219 including taxes. The manual car cost £1148. A specially trimmed A99 was sold as the
Princess 3-Litre, (note, not an "Austin" Princess – Austin was removed from Princess badging in August 1957 on the larger
Princess IV) and later under the Vanden Plas
marque as the
Vanden Plas Princess. A Wolseley version, the
6/99, was also produced. Production ended in 1961 with the introduction of the larger A110. 15,162 A99s were built. ==A110==
