In 1927–1928 Mercedes-Benz also expanded the range of the truck models, adding the small model 元/4 with the payload of 750 kg (3/4 ton), which was developed from the passenger car Typ 200 Nürnberg, and a heavy three axis model N56 with the payload 7-9 tons. To distinguish that, 6 cylinders versions of the trucks were referred sometimes as, for example, L1/6 or N2/6.

Therefore, in 1927–1928 most of the trucks from the series L1, L2, L5 were available with 4 or 6 cylinder engines. Four cylinders engines were discontinued only one year later. Also from 1927 Mercedes-Benz offered the more powerful 6 cylinders petrol engines (M16, M26 and M36) developing 50HP, 70HP and 100 HP. It was the world's first six-cylinder diesel engine, installed on the commercial vehicle. In 1927 Mercedes-Benz presented its first diesel engine (OM5), which immediately became a sensation. Mercedes-Benz L1 and L2 were the new models, but Mercedes-Benz L5 truck was basically a continuation of famous Benz 5CN truck, which was developed before the merge of Benz & Cie and Daimler-Motoren-Gesellschaft companies. The trucks were equipped with the 4 cylinders petrol engines (M14, M2 and M5), developing 45HP, 55HP and 70 HP. The models with the low chassis were N1, N2 and NJ5/N5 (N stood for Niederwagen, German word means a low car). The models with the standard chassis were L1, L2 and L5 (L stood for Lastwagen, German word for a truck, and the digit stood for the rated payload in tons). Also the low chassis has been used to build the buses.

Low chassis made sense especially that time to make easier loading and unloading of the vehicle. Each model was available with a standard and a low-frame chassis. The first Mercedes-Benz truck range, presented at the 1926 Berlin Motor Show (October) and at the 1927 International Motor Show for Trucks and Special Vehicles in Cologne (May) included three basic models with the payloads of 1.5, 2.5 and 5 tons.
