Editing Austin Sheerline (section)

==Engine==
The Austin Sheerline 4-Litre OHV straight-six engine was based on the famous [[Austin D-Series engine]], with slight differences.<ref name="austinmotorvehicleclubqld.org"/>

The first new British cars to be introduced since the war by one of the large manufacturers have now been announced. They are the Austin Sheerline 110 and Princess 120 saloons, the former with knife-edge coachwork made at Longbridge Birmingham and the latter having a more streamlined body which is the work of Vanden Plas, the coach building firm acquired by Austins last year. The chassis of both cars is similar, the only difference being in the number of carburettors. The figures after the names of the models indicate the brake horse-power. The cars are new from end to end, and the specifications include a new three and a half litre six-cylinder, overhead valve engine, steering column control of the four-speed synchromesh gearbox, independent front suspension using coil springs, and hydraulic brakes. The prices are £1,278 for the 110 and £1,917 for the 120, including [[purchase tax]].<ref>{{cite news | title=New Austin Cars | newspaper=The Times | date=14 March 1947 | page=6 | issue=50709}}</ref> designated A110, had a 3,460&nbsp;cc [[Straight-six engine|straight-six]] [[overhead valve]] engine but this was soon<ref>Austin Lorries Dealer<br />Increased prices for all Austin commercial vehicles come into force today. . . .  The change in engine size of the big Austin car from 3½-litres to 4-litres has been accompanied by alterations in the designation, and the two models on this chassis will be called in future the A125 Sheerline and the A135 Princess.

At 37 hundredweight (1,850&nbsp;kg) for the saloon and 2 tons (2,000&nbsp;kg) for the limousine this was a heavy car, and to maintain performance a low final drive ratio of 4.55:1 with 16-inch tyres was fitted. The saloon version had a top speed of {{convert|82|mi/h|km/h|abbr=on}}.

Anders Clausager, an archivist at BL Heritage Ltd, discovered that no more than 12 Sheerlines and 32 [[Austin Princess|Princesses]], mainly prototype and pre-production cars, were fitted with the 3,460cc engine before the increase to 3,993cc at the end of 1947.<ref name=wyatt />
