Mercedes Benz W111

The Mercedes-Benz W111 was a chassis code given to a range of Mercedes' vehicles produced between 1959 and 1971, including 4-door sedans (1959-1968) and 2-door coupes and cabriolets (1961 to 1971). It was built both in Stuttgart, Germany & Port Melbourne, Australia.

Mercedes-Benz emerged from World War II as an automaker in the early 1950s with the expensive 300 Adenauers and the exclusive 300SL grand tourers that gained it fame, but it was the simple unibody Pontons comprised the bulk of the company's revenues.  Work on replacing these cars began in 1956 with a design focused on passenger comfort and safety. The basic Ponton cabin was widened and squared off, with a large glass greenhouse improving driver visibility. A milestone in car design were front and rear crumple zones for absorbing kinetic energy on impact. The automaker also patented retractable seatbelts.  The exterior was designed for the European and North American markets. The body was modern and featured characteristic tailfins that gave the models their nickname — the fintail (German: Heckflosse).

Series production of the 4-door sedan began in August 1959, which made its debut at the Frankfurt Auto Show in autumn. Initially the series consisted of the 220b, 220Sb, and 220SEb. These replaced the 219 W105, the 220S W180 and the 220SE W128 Ponton sedans respectively. The 220b was an entry-level version with little chrome trim, simple hubcaps, and basic interior trim that lacked pockets on doors. Prices were DM16,750, 18,500 and 20,500, with a rough sales ratio of 1:2:1.  All models shared the 2195 cc straight-six engine carried over from the previous generation, producing 95 hp (71 kW) at 4800 rpm and capable of accelerating the heavy car to 160 km/h (155 if fitted with optional automatic gearbox). The 220Sb featured twin carburettors and produced 110 hp (82 kW) at 5000 rpm, raising top speed to 165 km/h (103 mph) (160 km/h (99 mph)) and improving 0–100 km/h acceleration to 15 seconds (16 on the 220b). The top range 220SEb featured Bosch fuel injection producing 120 hp (89 kW) at 4800 rpm, with top speed of 172 km/h (107 mph) (168 km/h (104 mph) for auto) and a 0–100 km/h in 14 seconds.
