Description
The Mercedes-Benz 230 Cabriolet B was the four-seat open touring variant of the W143 series, introduced in 1937 as one of the most versatile and elegantly balanced models in Mercedes-Benz’s mid-size six-cylinder range. Positioned between the intimate two-seat Cabriolet A and the formal four-door Cabriolet D, the Cabriolet B offered a harmonious combination of practicality, luxury and style. It appealed to buyers who wanted genuine four-passenger comfort in an open car without the scale or expense of Mercedes’ larger luxury cabriolets, making it one of the most admired and usable body styles of the period.
Power was supplied by the smooth and flexible 2.3-litre inline-six, producing around 55 horsepower. This engine was renowned for its quietness, reliable torque delivery and exceptional refinement. It offered relaxed acceleration and confident cruising, perfectly suited to touring with passengers. The four-speed manual gearbox, equipped with synchromesh on the upper gears, provided clean, precise shifting and contributed to the car’s civilised driving manners. The combination of six-cylinder smoothness and a well-matched transmission made the Cabriolet B an impressively refined mid-size car for the late 1930s.
The Cabriolet B was built on the long-wheelbase version of the W143 chassis, a configuration that provided generous interior space and a settled, comfortable ride. The ladder-frame construction offered strength and rigidity, essential for an open four-seat body. Independent front suspension with a transverse leaf spring and a swing-axle rear suspension with coil springs ensured a supple, stable and predictable driving experience. Mechanical drum brakes on all four wheels delivered dependable stopping performance. The longer wheelbase improved ride comfort but still allowed the car to feel balanced and manageable on winding roads.
Sindelfingen’s bodywork was one of the highlights of the 230 Cabriolet B. The proportions were elegant and cohesive: a long bonnet, sweeping front wings, four large side doors and a gracefully contoured rear deck that housed the folding roof. The fabric top, crafted from high-quality materials, provided good weather protection when raised and folded neatly to maintain the car’s flowing lines when lowered. With the roof down, the Cabriolet B became a classic pre-war tourer, open, airy and inviting. With the roof up, it retained a dignified, well-appointed presence, suitable for both leisure driving and formal occasions.
Inside, the Cabriolet B offered a spacious and welcoming cabin for four adults. The rear compartment, benefitting from the extended wheelbase, provided generous legroom and comfortable seating. Upholstery ranged from durable cloth for practical users to fine leather for buyers seeking greater luxury. The dashboard displayed the period’s characteristic Mercedes elegance, with clear instruments, polished wood or painted metal trim and finely made switchgear. The overall environment balanced durability with refined craftsmanship, giving the car a genuinely high-quality feel without excessive ornamentation.
On the road, the Mercedes-Benz 230 Cabriolet B delivered a pleasant, composed driving experience. The six-cylinder engine provided quiet, smooth power ideal for long-distance touring, and the suspension absorbed rough surfaces with ease. The long wheelbase gave the car a stable, comfortable gait at cruising speeds, while the open-top configuration made it particularly enjoyable for scenic drives. The Cabriolet B was not intended for sporting use, but for relaxed, elegant motoring with enough power and refinement to ensure comfort over extended journeys.
The Cabriolet B occupied an important middle ground in the W143 lineup. It offered far more space and practicality than the Cabriolet A, yet remained less formal and more manoeuvrable than the larger Cabriolet D. This versatility made it popular among well-to-do families, touring enthusiasts and private owners who wanted a stylish, high-quality open car that could accommodate four passengers without compromise. Production numbers were relatively modest, as the body style required extensive handcrafting, which adds to its desirability today.
In the present day, the Mercedes-Benz 230 Cabriolet B is regarded as one of the most appealing and collectible variants of the W143 series. Its combination of graceful Sindelfingen design, smooth six-cylinder refinement and genuine four-seat open-top usability gives it a unique place in pre-war Mercedes history. Well-preserved examples embody the craftsmanship, mechanical quality and elegant touring spirit that defined Mercedes-Benz in the late 1930s, making the 230 Cabriolet B a prized and evocative reminder of the company’s finest pre-war achievements.
