Laurin & Klement Shareholding Company is founded. The successful L&K type F four-cylinder is launched on the market The company’s range now consists of nine models, from a small two-cylinder passenger car and a four-cylinder racing car to transporters and omnibuses. An FF-type engine constructed from two four-cylinder F-model drivetrains is one of the first eight-cylinders to have ever been built.
The L&K Type-F racing version wins big in all of its categories at Semmering. The first small four-cylinder type G is launched on the market.
