BMW 3/15 PS DA 4 Model

Production Period: Mid-February 1931 and onwards

In mid-February 1931, BMW launched the third generation of its 3/15 PS model, designated the BMW 3/15 PS DA 4. This new iteration of the Dixi's successor marked a significant evolution in design, particularly in terms of interior space and comfort.

One of the key modifications was the lengthening of the superstructure by approximately 20 centimeters. This adjustment allowed for a more generous interior, offering enough room to comfortably accommodate four adults, thus enhancing the car's practicality for families or groups. Additionally, the small trunk at the rear was removed, further increasing passenger space.

The production process began with the conversion of the sedans to the new specification, followed by other body styles, including two-seaters, coupés, and touring cars. However, by the introduction of the DA 4, the production of the two-seater and three-to-four-seater convertibles was discontinued.

With these changes, the BMW 3/15 PS DA 4 provided a more spacious and comfortable experience for drivers and passengers, cementing its place as a practical and popular choice in the 1930s automotive market.

Construction Period: January 1931 - February 1932

In the final model year of the BMW 3/15 PS DA 4, several improvements were made to the sedan version to address issues previously criticized by both consumers and automotive experts. One of the main concerns had been the lack of space and the hard front suspension, and BMW sought to improve both aspects.

Design modifications included significant reinforcements to the all-steel body, ensuring greater durability. The interior length was increased by 20 cm, which was especially advantageous for passengers in the rear seats, providing them with more legroom and comfort.

Additionally, BMW introduced a new front swing axle, which was intended to enhance road holding and driving safety. The new suspension system aimed to offer a smoother ride and better handling on various terrains.

However, despite these efforts, the softer cushioning of the new suspension did not deliver the expected results. Instead of improving stability, the adjustments led to reduced overall stability and directional stability, which attracted negative reviews from the trade press. The sedan's handling issues and its inability to fully address the desired improvements led to criticism from automotive experts and consumers alike.

Despite these setbacks, the BMW 3/15 PS DA 4 Sedan continued to be a significant model in the brand's history, offering improvements in comfort and design, though falling short in terms of performance and driving dynamics.

Construction Period: January 1931 - February 1932

Launched in January 1931, the BMW 3/15 PS DA 4 Coupé represented the final bodywork version of the 2-seater convertible. The target audience for this model was primarily professionals who needed to travel long distances overland, often with significant luggage, but still desired high comfort and the ability to maintain high average speeds during their journeys.

This coupé was designed with perfect weather protection, ensuring that drivers and passengers were shielded from the elements during travel. The inclusion of a large trunk made the car particularly suitable for business travelers, such as medical practitioners, who required space for luggage or equipment.

In terms of convenience, the wide doors provided easy entry and exit, while the comfortable seating ensured that long trips could be completed with ease. Additionally, the low running costs of the coupé were an attractive feature, making it a practical choice for those who needed an efficient and reliable vehicle for frequent travel.

Marketing efforts for the BMW 3/15 PS DA 4 Coupé were directed towards individuals who spent much of their time on the road, emphasizing its practicality, comfort, and affordability. As a result, it became a popular choice among business travelers seeking a reliable, comfortable, and cost-effective vehicle.

Construction Period: January 1931 - November 1931

The BMW 3/15 PS DA 4 Phaeton (also known as the Touring Car) was part of a limited product range within the DA 4 model series. This version retained the wood/steel body construction of the previous models, but it was uniquely designed with a leather canopy roof, making it an open-top version ideal for those seeking a more open-air driving experience.

The bodywork of the Phaeton remained largely unchanged from the earlier DA 2 models, except for one significant modification: the front rigid axle was replaced by the newly developed swing axle. This alteration aimed to enhance the vehicle's handling and comfort, offering improved road holding and a smoother ride for passengers.

While the DA 4 Phaeton offered fewer variations compared to its predecessors, its elegant design and the appeal of an open-top vehicle made it a standout in the BMW lineup of the time. It continued to embody the characteristics of affordability and versatility, catering to drivers who appreciated both style and practicality.

The BMW 3/15 PS DA 4 Open-Top Two-Seater was one of the limited versions produced within the DA 4 model series. This variant was characterized by its affordably priced wood/steel body, offering an accessible option for those seeking an open-top driving experience. Like the touring cars, it was equipped with a leather canopy roof, providing a more rustic charm while allowing drivers to enjoy the open air when desired.

The bodywork of the DA 4 Open-Top Two-Seater was nearly identical to that of the DA 2 model, with the only significant difference being the replacement of the front rigid axle with the newly developed swing axle. This modification was designed to improve the car’s road handling and comfort, offering a more refined driving experience.

Despite the limited production and fewer model variants, this two-seater continued BMW's tradition of producing vehicles that combined economical pricing with stylish design, perfect for those who sought both performance and practicality in a compact, open-top car.
