The Laurin & Klement 105 is a passenger car model. It was the successor of the Type 100 from 1922. It was also known as the 7/20 HP. The car came out in 1923 with various bodies being available.

Just like its predecessor, the water-cooled, side-valve four-stroke engine with a L-head had a displacement of 1791 cm ³ and a power output of 20 hp (15 kW). This accelerated the car up to 80 km/h. The chassis of the car consisted of riveted steel U-profile beams.

The only visible difference with the previous model was a spare tire being mounted left of the hood.
