The Mercedes Simplex 40 HP model was the further evolution of the 35 HP model introduced in 1901. Actually Simplex was a line of road and racing cars produced by Daimler in 1902 – 1908 with the engine power ranged from 40 to 60 hp. The 1902 racing car was built around the same chassis as 1901 35 HP. The major difference was more the powerful 5,3 litre straight 4 engine capable to develop 40 hp. Emil Jelinek received first Simplex cars in March of 1902 for traditional Nice racing meeting. The speed week at Nice that year was restricted to annual climb up La Turbie hill, and speed trials on the Promenade des Anglais. E.T. Stead on new Mercedes-Simplex 40 hp won the 5th La Turbie. Major event of the year was Paris – Vienna race, where 4 Mercedes cars were entered, but only Elliot Zborowski was able to finish. He took 2nd place, 13 minutes behind the winner, Henri Farman in Panhard-Levassor 70 HP. Later in August that year Willhelm Werner won in 40HP Simplex the Frankfurt Circuit Race. The scale model by IXO from the Mercedes-Benz Officielle Kollektion is almost the same as 1901 model from IXO Museum series.
