The first generation of the large Farinas was introduced with the
Austin A99 Westminster, with the
Wolseley 6/99 following shortly after in 1959 to replace the
6/90. It used the same 2.9 L (2912 cc)
C-Series straight-6, , twin SU carburettor engine from the
Austin-Healey 3000. The suspension was the conventional BMC arrangement of coil springs and wishbones at the front with a live axle and semi elliptic leaf springs at the rear. An anti-roll bar was fitted at the front. Lockheed
disc brakes were fitted at the front with
drum brakes at the rear and vacuum servo assistance. The interior was finished in luxurious style to distance the Wolseley from its Austin stablemate. The dashboard was polished wood as were the door cappings. Leather upholstery was used on the two front seats and rear bench seat which had a fold down central arm rest. A choice of single or duo-tone colour schemes was offered. Wolseley 6/99s with left hand drive shipped to Canada used the 4-speed floor mounted shift with overdrive identical to that in the Austin-Healey 100/6 and 3000.
The Motor magazine tested a 6/99 with overdrive in 1959 and recorded a top speed of and acceleration from 0– in 14.4 seconds. A "touring" fuel consumption of was recorded. On the home market, as tested with overdrive, it cost £1254 including taxes of £369. ==Wolseley 6/110==
