Maybach W5

The Maybach W 5 was a Maybach passenger car that followed the W 3 and was sold as the Type 27/120 PS. German Wikipedia says it followed in 1927, although its own model list dates the car 1926 to 1928, and it records that the car was developed further in 1928 into the W 5 SG, where SG stands for Schnellgang, the name of a gearbox with a fast top gear. About 300 were built including the SG version. Like all Maybach cars of the period it left the factory as a bare chassis, so the bodies seen on surviving cars were chosen and built to each buyer's order. The source gives no engine details for this model.
