Austin Westminster A99

The Austin Westminster A99 designed by Pininfarina features 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 10.75 in (273 mm) 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 98.1 mph (157.9 km/h), acceleration from 0–60 mph (97 km/h) in 17.9 seconds and a fuel consumption of 23.0 miles per imperial gallon (12.3 L/100 km; 19.2 mpg‑US). The test car cost £1219 including taxes. The manual car cost £1148. A specially trimmed Austin Westminster 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.
