The Mercedes-Benz W188 was a two-door luxury sports tourer produced by Mercedes-Benz between 1951 and 1958. The company's most expensive and exclusive automobile, the elegant, hand-built two-door 300 S (1952-1955) and its successor 300 Sc (1955-1958) were the pinnacle of the Mercedes line of their era.

The pair's conservative styling belied their technological advances,[1] sharing numerous design innovations and mechanical components with the iconic Mercedes-Benz 300 SL "Gullwing", including engine, suspension, and chassis.

In addition, it shared other refinements with Mercedes' flagship four-door (W186) 300 "Adenauer" sedan, including a pedal-operated chassis central lubrication system, and a dashboard operated electrical torsion-bar activated rear load-leveling suspension leveling system.[2]

The W188 was available as a hard-topped coupe, a cabriolet, and a roadster (fitted with a lighter, fully retractable soft top without the cabriolet’s heft and large landau bars).

A total of 760 W188s were produced between 1952 and 1958, 560 300S and 200 300 Sc.

300 S

The 300 S (W188) was introduced at the Paris Salon in October 1951. It was available as a 2-seat roadster, 2+2 coupé, and cabriolet (officially the Cabriolet A). Although mechanically similar to the much larger contemporary four-door (W186) 300 "Adenauer" sedan, the additional craftsmanship, visual elegance, and 50% higher price tag elevated the W188 series to the apex of its era's luxury cars.[3]

The 300 S was fitted with a high-performance M188 version of the W186's 3.0 L (2996 cc/182 in³) overhead cam, aluminum head M186 straight-6, the M188. Designed to give reliable service under prolonged hard use, the engine featured deep water jackets, an innovative diagonal head-to-block joint that allowed for oversized intake and exhaust valves, thermostatically controlled oil cooling, copper-lead bearings, and a hardened crankshaft. Triple Solex carburettors and 7.8:1 compression and raised maximum output to Script error: No such module "convert". at 5000 rpm.

From July 1952 to August 1955, a total of 560 300 S automobiles were built - 216 Coupés, 203 Cabriolet As, and 141 Roadsters were produced.Template:Sfn[4]

The 300 Sc (W188) appeared in 1955, featuring upgrades to both its engine and suspension derived from the high-performance 300SL Gullwing introduced a year earlier and the (W186) 300c, its most advanced version. These included the Sc's new M199 inline-six receiving a significantly detuned version of the 300 SL's M198 mechanical direct fuel-injection system, and a rear suspension improvement from the 300c.[5]

With an increased 8.55:1 compression ratio, the M199 produced Script error: No such module "convert". at 5400 rpm, and Script error: No such module "convert". at 4300 rpm.[6]

Prices rose to DM 36,500, and a total of 200 300 Sc's were built - 98 Coupés, 49 Cabriolet As, and 53 Roadsters through April 1958.Template:Sfn
