A piston engine is undersquare if its cylinders have a smaller bore (width, diameter) than stroke (disambiguation) (length of piston travel). This can be a negative trait, since a longer stroke means greater friction and a weaker crankshaft. An undersquare engine usually has a lower redline than an oversquare one, but it may generate more low-end torque. Many United Kingdom automobile companies used undersquare designs through the 1950s, largely as a result of a motor tax system that taxed cars by their cylinder bore. Therefore, many of the most famous cars of that era use this design. This includes the Austin A-Series engine and many Nissan derivatives. ==See also== * Oversquare * Power engine technology
