1936 AC 1670 March Special Sports Tourer

1936 AC 16/70 four-seat roadster with Earl of March coachwork.This typical 1930s English tourer was made by the AC Car Company of Thames Ditton, West of London. The car is hand-made of aluminium on ash wood framing with wings of steel, all mounted on an under-slung Standard chassis shared with its contemporary, the SS90. There were only nine four seaters made in 1936 and only 55 in total between 1933 and 1936. The engine is AC's own 6 cylinder 2 litre device that employs wet liners in mostly aluminium castings with the exception of the iron head. The single overhead cam design was advanced for its time in 1920 when it first appeared and enabled it to survive in development into the early '60s, the horsepower rising from 35 bhp in its original single carbureted form to over 100 bhp with three SUs. This car has triple SUs and is rated at 70 bph as the name implies. Brakes are self energizing, by Bendix, employing the typical rods and cables of the day, and while the hand brake works on all four wheels its 'fly-off' action can catch out the unwary.
