Mercedes-Benz 8/38 PS classic cars for sale

History of the Mercedes-Benz 8/38 PS

The Mercedes-Benz 8/38 PS marked a pioneering era for Mercedes-Benz after WWI. Launched as the W 02 series, its name derived from its 8 'Steuer-PS' for tax classification and 38 'Pferdestärken' (metric horsepower). The newly engineered M02 straight-six petrol engine with 2.0 litres displacement offered smoothness and longevity, a vital quality in the growing private transport sector of the 1920s. The 8/38 PS set the technical and stylistic tone for subsequent generations – notably, its 1926 evolution into the 'Stuttgart' model with minor but important style adjustments, reflecting the transition in automotive design language of the era.

Model History

The precursor of the 8/38 PS was the pre-merger Benz and Daimler models, transitioning into a unified Mercedes-Benz product lineup post-1926. The W 02 series was influential as it introduced new construction methods and a more refined chassis. Its direct successor, the enhanced 'Stuttgart' model, further improved on driving dynamics and stylistic cues while keeping the core mechanical DNA—specifically the robust inline-six engine and consistent use of rear-wheel drive. The model history is defined by a shift from technical experimentation towards a more standardised and recognisable Mercedes-Benz identity.

Highlights of the Mercedes-Benz 8/38 PS

The 8/38 PS is renowned for its robust 2.0 litre, six-cylinder M02 engine delivering 38 PS at 3400 rpm, and a notable maximum torque of 98 Nm at just 1400 rpm. Buyers in the 1920s enjoyed a choice of body variants—including saloon, coupé, and cabriolet—often featuring rare details like opposing 'suicide' doors or hidden Mercedes-Benz engravings at the rocker panel. The car balanced flowing rounded lines with square cabin geometry, giving it a distinctive, well-proportioned look.

Technical Data

Special Editions and Collectible Models

The 8/38 PS was available in a range of body configurations: classic saloon, elegant coupé, and various cabriolet forms. Some variants stand out for their rare door mechanisms—such as rear-hinged 'suicide' doors or counter-opening types—providing additional collector interest. Limited-production coachbuilt bodies offered further exclusivity, often with custom engravings and unique interior trim combinations.

Weak Spots and Common Issues

No specific weak spots are reported in the provided sources. However, for a vehicle of this vintage, particular attention should be paid to engine lubrication (especially crank bearings), carburettor calibration, and the structural integrity of coachbuilt bodies—especially around door hinges and rocker panels where hidden corrosion can occur. The manual gearbox and rear axle should also be regularly checked for oil leaks and wear.

Engine, Performance, Transmission and Handling

The 8/38 PS delivers a harmonious blend of period-typical dynamics and comfort. Its straight-six engine provides balanced power output for its era, with 38 PS ensuring steady cruising and the full 98 Nm of torque accessible at low revs. The 3-speed manual gearbox requires deliberate shifting and rewards precise input. Weight distribution, aided by a 2.81 m wheelbase, gives the car a confident stance and comparably stable handling for a prewar saloon, even at its stock ride height and with period suspension components. Saloon and Cabriolet variants with special door configurations or coachbuilt features are particularly remarkable due to their rare blend of engineering and period coachwork.

Interior, Comfort, Exterior and Design

Design of the 8/38 PS is defined by a balanced interplay of round flowing contours and the square, upright architecture of the cabin. The car’s relatively high standing stance emphasises its practical dimensions (438 cm long, 168 cm wide, 180 cm high). Notable details include Mercedes-Benz engravings strategically placed but discretely hidden, as well as interior variations adapted for luxury or utility. Multiple body colours and cabin materials offered buyers bespoke options; some models included ornate wood trim and period-correct upholstery combinations. Accessories such as period luggage racks and custom wheel covers were available, and body forms ranged from four-door limousines to sporty two-door cabriolets.

Other Relevant Features

Left-hand drive configuration as standard, an unusual feature for its day. The model played a significant role as a blueprint for subsequent Mercedes-Benz generations, both in technical and stylistic development. Coachbuilt variations sometimes included quasi-experimental features not seen on later models.

Summary

The Mercedes-Benz 8/38 PS remains a touchstone for prewar German engineering, combining a reliable straight-six engine, versatile body styles, and characteristic period details. It continues to define its era in the classic car market, supported by comprehensive supply and demand, and serves as a reference point for enthusiasts and collectors interested in the roots of the Mercedes-Benz brand.
