Hudson Eight Boattail Roadster

Car producer : 



Eight Boattail Roadster





For the 1930 model year Hudson debuted a new flathead inline eight cylinder engine with block and Crankcase cast as a unit and fitted with two cylinder heads. A 2.75-inch bore and 4.5-inch stroke displaced 218.8 cubic inches developing 80 horsepower (60 kilowatts; 81 metric horsepower) at 3,600 rpm with the standard 5.78:1 compression ratio. Hudson's only straight-eight engine would remain in production up to 1952. For its debut year of 1930 the Great Eight was offered in two wheelbase lengths - 119" (Model T) and 126" (Model U) - there being a total of 11 different body styles to choose from. 1931 saw minor changes, with little modified mechanically and most of the focus directed at cosmetic differences. The 5 main bearing crankshaft had 8 integral counterweights, an industry first, and also employed a Lanchester vibration damper. Four rubber blocks were used at engine mount points. A valveless oil pump improved the Hudson splash lubrication system. The new eights were the only engine offering in the Hudson line, supplanting the Super Six, which soldiered on in the Essex models.
