High Quality Content by WIKIPEDIA articles! The Bentley Mark VI was the first post-war luxury car from Bentley. Produced from 1946 to 1952, it was also the first car from Rolls-Royce with factory coachwork but chassis were still also supplied to independent coachbuilders . The chassis and engine went on to be used as the basis of those in the Rolls-Royce Silver Wraith of 1946 and Silver Dawn of 1949. The Mark VI used an F-head straight-6 engine 4.3 L (4257 cc/259 in³) in size. In 1951, a 4.6 L (4566 cc/278 in³) version of the engine was introduced. A four speed syncromesh manual transmission was fitted with the change lever to the right of the driver on right hand drive cars and on the column on left hand drive versions. The 4.3 L was referred to as the 4¼ L with a single exhaust and the 4.6 L as the 4½ L with a twin exhaust. The chassis used leaf springs at the rear and independent coil springing at the front with a control on the steering wheel centre to adjust the hardness of the rear springing. A central lubrication system allowing oil to be applied to moving parts of the suspension from a central reservoir was fitted.
