European car sales jumped 10.7% in September 2025, driven by a plug-in hybrid explosion that signals automakers are choosing profitable hybrids over money-losing pure electric vehicles to meet emissions targets. But the real story lies beneath the headline numbers: Tesla’s sales dropped 10.5% while Chinese rival BYD surged 398%, according to data released Tuesday by the European Automobile Manufacturers’ Association.

The September surge marks the third consecutive month of growth for Europe’s struggling car industry, which faces mounting pressure from high production costs, U.S. import tariffs, and a slower-than-expected electric vehicle transition. New vehicle registrations across the European Union, Britain, and the European Free Trade Association reached 1.237 million cars, driven partly by new model launches.

Traditional Automakers Gain While Tesla Bleeds Market Share

Germany and the UK led the September gains, with sales climbing 12.8% and 13.7% respectively. Spain posted a 16.4% increase, Italy rose 4.2%, and France managed just 1% growth. Traditional European manufacturers posted solid results: Volkswagen registrations increased 9.7%, Stellantis climbed 11.5%, and Renault surged 15.2% year-over-year.

Tesla’s decline tells a different story. The American EV maker’s market share shrank to 3.2% from 4.0% a year earlier, extending a months-long collapse that saw the Model Y plummet to 60th place in July before recovering to first place in September with declining volumes. Meanwhile, BYD’s 398% sales explosion lifted its market share to 2% from just 0.4% in September 2024, continuing the Chinese automaker’s aggressive European expansion that first overtook Tesla in April 2025.

The PHEV Pivot: Automakers Choose Profits Over Pure Electric

The September numbers reveal a strategic shift in Europe’s electrification roadmap. Plug-in hybrid sales exploded 65.4%, while battery-electric vehicles rose a comparatively modest 20% and conventional hybrids increased 15.9%. Collectively, electrified vehicles (battery-electric, plug-in hybrid, and hybrid-electric) captured 64% of registrations, up from 57% in September 2024.

But ACEA’s assessment carries a warning. The trade group noted that “the battery-electric car market share held steady at 16.1% YTD, still below the pace required at this stage of the transition.” Through the first nine months of 2025, Europe registered 1.3 million battery-electric cars, with growth concentrated in Germany (+38.3%), Belgium (+12.4%), and the Netherlands (+3.9%). France, by contrast, saw a slight 0.2% decline despite an 11.2% year-over-year gain in September alone.

The PHEV surge reflects economic reality for struggling automakers. As EVXL previously reported, plug-in hybrids offer a profitable middle ground for manufacturers grappling with high production costs and consumer reluctance toward premium-priced pure electric vehicles. By producing cars that technically qualify for emissions credits while remaining affordable and profitable, automakers can meet regulatory requirements without bleeding cash on money-losing BEVs.

Chinese Brands Double Market Share As Western Automakers Stumble

The competitive landscape shifted dramatically in September. Chinese brands more than doubled their European market share to approximately 5.1% for the first half of 2025, now trailing Mercedes-Benz by just 0.1 percentage points. BYD led the charge with aggressive pricing and rapid product rollouts, while brands like MG (owned by SAIC Motor), Jaecoo, Omoda, and Leapmotor made substantial gains.

Europe’s automotive giants face mounting challenges. Volkswagen, despite posting September gains, continues grappling with factory closure considerations for the first time in its 87-year history. The German automaker’s software division Cariad reported a €2.4 billion ($2.6 billion) loss in 2023, while its core EV lineup struggles against faster-moving Chinese competitors with development cycles of two years versus VW’s eight-plus years.

Stellantis faces similar pressure with an aging combustion-engine lineup and EV pricing challenges. The group’s new CEO Antonio Filosa inherited a portfolio where profitable gas vehicles subsidize loss-making electric models, creating what industry analysts describe as an unsustainable long-term business model.

Supply Chain Disruptions Loom As Transition Stalls

Beyond the sales numbers, Europe’s car industry confronts immediate threats. A standoff between China and the Netherlands over chipmaker Nexperia threatens supply disruptions that could halt vehicle manufacturing. U.S. import tariffs continue draining billions in earnings from European automakers with significant American operations. And the gap between regulatory mandates and market reality widens as battery-electric adoption falls below the pace needed to meet 2027 targets.

Hybrid-electric vehicles emerged as the most popular powertrain choice, capturing 34.7% of the market through September. Meanwhile, petrol and diesel registrations declined sharply, with gasoline dropping 18.7% and diesel falling 24.7% year-to-date. Petrol’s market share contracted to 27.7% from 34.4% a year earlier, while diesel collapsed to just 9.3%.

EVXL’s Take

The September surge masks a troubling reality for Europe’s electric transition. Automakers aren’t accelerating toward zero-emission futures—they’re retreating to profitable plug-in hybrids while pure battery-electric adoption stalls at 16.1%, well below regulatory targets.

We’ve been tracking this pattern for months at EVXL. When European EV sales plummeted in August 2024, the writing appeared on the wall: consumers balked at premium pricing while automakers struggled with profitability. The PHEV boom in May 2025 confirmed the industry’s strategic pivot toward vehicles that check regulatory boxes without requiring the massive battery investments that make pure BEVs unprofitable.

Tesla’s continued decline reveals another uncomfortable truth: when European consumers can directly compare value, performance, and price, Chinese competitors consistently win. BYD’s 398% explosion follows a pattern we documented throughout 2025—first overtaking Tesla in April, then posting stunning gains with models like the Seal U that surge 833% while offering comparable technology at substantially lower prices.

Volkswagen’s September gains shouldn’t distract from its existential crisis. The company faces potential German plant closures, a €2.4 billion software disaster, and Chinese competitors who develop new models in two years versus VW’s eight. When your EV strategy falters this badly, a 9.7% monthly bump won’t save you.

The real question isn’t whether Europe’s car sales are recovering—it’s whether this PHEV-fueled “recovery” represents a strategic retreat from the electric transition. With battery-electric share stuck below targets and automakers flooding the market with profitable hybrids instead of investing in money-losing pure BEVs, Europe may be choosing short-term profitability over long-term electrification.
