Car company mergers: what happens when two automakers join forces?

The auto industry is constantly evolving, and when two major car brands merge, it’s a big deal. Recently, reports surfaced about Honda and Nissan exploring a potential partnership, a move that—if it happens—could reshape the Japanese car market and influence global competition. While no deal is official yet, this kind of strategic alliance isn’t new. Over the years, automakers have joined forces for innovation, survival, or market domination, sending ripple effects through production lines, dealerships, and even your next car purchase.

From streamlining operations to reshaping the vehicles we drive, car company mergers aren’t just corporate headlines—they change the entire landscape of the industry. So, what actually happens when automakers merge? Let’s take a drive through the mechanics of an automotive merger.

Streamlining operations (a.k.a. cutting costs)

Running an automotive brand isn’t cheap—R&D, manufacturing, marketing, and supply chain logistics all add up. By joining forces, companies can cut redundant costs, share production facilities, and negotiate better deals with suppliers.

This usually leads to more efficient operations, but it often comes with tough decisions. Plant closures, workforce reductions, and restructuring can follow, as companies eliminate redundancies to stay profitable.

Shared technology and innovation

Merging means pooling resources, which is especially crucial in a time when electric vehicles (EVs) and autonomous technology are transforming the market. Instead of spending billions separately on battery tech, AI software, and fuel efficiency, two companies can fast-track innovations together.

This is why many mergers lead to exciting new models, hybrid platforms, and major safety advancements. According to the International Energy Agency (IEA), automaker collaborations on EV production are driving down manufacturing costs and accelerating battery advancements, making electric vehicles more accessible.

Brand identity and market positioning

When two car companies merge, they need to figure out their brand strategy. Does one take over while the other fades into the background? Or do both continue independently while sharing engineering and production behind the scenes?

Some mergers lead to brand consolidation, while others allow companies to maintain their identities but operate with shared resources. Think about past partnerships—some brands disappeared entirely, while others evolved into stronger, more innovative competitors.

More choices… or fewer?

At first, a merger might seem like great news for car buyers—more collaboration could mean new models and better technology. But behind the scenes, automakers don’t want to compete with themselves.

If two merging brands both make a midsize SUV, for example, one of them might get the axe to avoid internal competition. While this can result in better-designed cars, it can also reduce options in certain segments.

The impact on dealerships and customer service

Mergers shake up dealership networks as brands consolidate, expand, or phase out locations. This means some dealerships may close, while others gain more offerings.

For customers, this can affect warranty programs, service availability, and even how easy it is to find replacement parts for older models. In fact, customer satisfaction often takes a hit after a major merger. According to Smithers, companies that acquire another brand typically see a 3% drop in customer satisfaction over the first two years as operations adjust.

What it means for used and junk cars

Mergers don’t just affect new cars—they shake up the used and junk car markets, too.

If a brand gets discontinued, its used models might lose value faster due to limited parts and service availability. On the other hand, a successful merger can boost demand for older models, making them more valuable in resale and junk car pricing.

The road ahead

Automotive mergers reshape the industry, influencing everything from the cars we drive to how much we pay for them. Whether they lead to groundbreaking innovation or the loss of familiar brands, one thing is certain—the road ahead is always changing.
