The Mercedes-Benz W222 is the version of the Mercedes-Benz S-Class produced since 2013, and the successor of the Mercedes-Benz W221.
 The W222 was designed during 2009.
 The original design proposal of the car was created by Il-hun Yoon, a Korean designer, who was inspired by the Mercedes-Benz F700 concept car.
 The exterior design was developed by a team of designers under the direction of Robert Lešnik.
 W222 has a similar design theme to the CLA-Class and Pre-Facelifted E-Class (W212).
The Mercedes-Benz SLS AMG (C197 / R197) is a front mid-engine, 2-seater luxury, limited production supercar automobile developed by Mercedes-AMG of German automaker Mercedes-Benz and was the first Mercedes-Benz automobile designed in-house by AMG.
 The car, which has gull-wing doors, was the successor to the Mercedes-Benz SLR McLaren and was described by Mercedes-Benz as a spiritual successor to the Mercedes-Benz 300SL Gullwing.
 SLS stands for "Sport Leicht Super" (Sport Light Super).
 The Mercedes-Benz SLS AMG was assembled largely by hand, with its chassis and aluminum body shell produced by Magna Steyr in Graz, Austria and then transferred to Sindelfingen, Germany for assembly, with its engine being hand built by AMG in Affalterbach, Germany.

The Mercedes-Benz W 21 was a six-cylinder passenger car launched in 1933 using the name "Mercedes-Benz Typ 200".
 It was one of several Mercedes-Benz models known, in its own time, as the Mercedes-Benz 200 (or sometimes, in this case, as the Mercedes-Benz Typ(e) 200) and is therefore in retrospect more commonly referred to using its Mercedes-Benz works number, “W21”.
Mercedes-Benz W202 is a compact executive car which was produced by the German automaker Mercedes-Benz in 1993–2000, under the C-Class model names.
 In May 1993, the first generation Mercedes-Benz C-Class was introduced as a replacement for the 190.
 The C-Class sedan was the company's entry-level model up until 1997, when Mercedes-Benz launched the smaller A-Class.
 Styling themes were carried over from the previous W201 series, but the new series had a smoother and rounder design than the previous generation of the compact Mercedes-Benz.
The Mercedes-Benz Typ 380 is an eight-cylinder powered automobile introduced by the German manufacturer Mercedes-Benz at the Berlin Motor Show in February 1933.
 It was withdrawn from production during 1934.
 Several models with similar names were produced by Mercedes-Benz during the 1930s (and again in the 1980s), so that in retrospect the car is frequently identified using the manufacturer's Works Number as the Mercedes-Benz W22.
 (The car is sometimes referred to as the Mercedes-Benz Typ 380 K, presumably because of the "Kompressor" (Supercharger) fitted on the faster cars, but this designation was never officially used by the manufacturer.)
The Mercedes-Benz AMG C-Coupé DTM is a third generation touring car (DTM) constructed by the German car manufacturer Mercedes-Benz.

 The new car is the successor to the AMG Mercedes C-Class, which scored 84 victories in 156 races to become the most successful vehicle in the 27-year history of the DTM.
The Mercedes-Benz W25 was a Grand Prix racing car designed by Daimler-Benz AG for the 1934 Grand Prix season, in which new rules were introduced, and no championship was held.
 In 1935, the European Championship was resumed, and it was won by Rudolf Caracciola in a W25.
 In modified form, the W25 remained in use until 1937, when it was succeeded by the Mercedes-Benz W125.
