Japanese OEMs race to halve development time as China gains

Chinese brands outsold their Japanese rivals in Europe over a full quarter for the first time in the three months to September, taking 12.7% of registrations against 11.9% for Japanese manufacturers including Toyota, according to figures reported by Dataforce. In September alone the Chinese share reached a record 14.5%, almost three percentage points above August. Five years ago it was barely 1%.

Europe tips first

The surge was led by hybrids, and registrations of Chinese-branded cars roughly doubled from a year earlier. Chery’s Jaecoo 7 SUV topped the UK sales charts in March and again in September. At the Paris Motor Show earlier this month, Chery, BYD and Zeekr, part of Geely Holding Group, brought well-priced models, among them the BYD Dolphin G DM-i, a compact plug-in hybrid developed specifically for Europe.

But Japanese carmakers did not arrive yesterday. Toyota has sold cars in the region since 1963 and runs factories across the continent, while Nissan has built vehicles at Sunderland in the UK since 1986. The newcomers are now closing the gap on that footprint as well. Chery is preparing production in Barcelona and BYD is nearing completion of a manufacturing site in Hungary.

Mercedes-Benz and other European carmakers have welcomed the political backing behind Made in Europe rules but warned that they could distort global supply chains and push up costs.

The gap is measured in years

The Europe result is a sales story, but the cause sits in the engineering department. Japanese carmakers typically take four to five years to develop a new vehicle, whereas some Chinese rivals are reported to do it in under two.

Bernama-Kyodo, the source of the comparison, stresses that these are broad figures rather than fixed timelines for every model. Even so, the direction is clear enough to have moved Toyota, Honda, Nissan, Suzuki and Mitsubishi Motors to act, with some targeting cuts of up to 50%.

Nissan stops reinventing the platform

Nissan’s answer is a family-based approach in which similarly sized vehicles share common underpinnings. It aims to cut lead time on a new SUV for North America, due in 2028, to three years and one month. Derivatives built on that base would then take two and a half years, a reduction of up to 40%. The strategy is expected to cover 80% of Nissan’s global volume and to eliminate 70% of its distinct part types. The 40% figure applies to derivatives on an established platform, not to every all-new Nissan.

“This is a reform to become a company that responds to changes and delivers good cars in a timely manner,” said Hidemi Sasaki, deputy general manager of Nissan’s product planning division.

Nissan is not working alone. In August 2026 it and Honda announced a joint development agreement to standardise selected electronic control units and software, with application planned from fiscal 2029.

Japan Inc turns to shared parts in fight against China

Toyota's Koji Sato is asking Japan's seven carmakers to standardise the parts drivers never see, from wiring looms to steel grades, as Chinese rivals erode market share and force a rethink of decades-old rules of competition.

Honda, Toyota and the rest

In this fight for accelerated programme times, Honda has gone furthest - on paper. Its Triple Half programme aims to halve development time, cost and engineering workload against 2025 levels, leaning on artificial intelligence, digital engineering and streamlined processes. Minor model changes begin under the scheme in fiscal 2026, and full model-change projects entering development in 2028 follow. The urgency is financial too, because Honda posted its first net loss in the previous fiscal year.

Toyota is attacking complexity on the shop floor. Its Area 35 initiative cuts part variations in line with demand trends, with the goal of raising plant floor space utilisation by 35%. Early trials at 10 Japanese plants reportedly freed capacity for an additional 80,000 vehicles a year, plus development resources equal to three full model-change projects.

Suzuki wants to halve its cycle to roughly two years, and Mitsubishi Motors aims for a 20% reduction to about three years by around 2030.

What compression does to suppliers and quality

Shorter programmes, however, land hardest on the supply base with consequences across the value chain. By condensing development to 24 to 36 months, Japanese carmakers will push tier-one suppliers across Asia to standardise tooling and shorten quotation windows, according to RetailNews Asia’s analysis.

The same analysis notes that Chinese carmakers have accepted higher initial defect rates and used over-the-air software updates to compensate for compressed testing, while Japanese brands built their pricing power on mechanical durability and strict pre-production validation.

Copying the Chinese bargain would put that reputation at risk, and neither Honda after its loss nor Nissan with eroded margins has much room to absorb a wave of recalls.

Despite all this, speed is not everything, and Chinese executives say so themselves. Earlier this year GWM chairman Wei Jianjun acknowledged that Chinese carmakers still trail established global manufacturers in manufacturing experience and technical expertise. Crashworthiness, durability, powertrain, electronics and software validation cannot be skipped. What shared platforms and digital simulation can do is remove duplicated work, which is where the time is being found.

Speed has become the entry ticket. Keeping the validation discipline that made Japanese cars worth buying is the part no rival’s playbook can supply, and the 2028 launches from Nissan and Honda will reveal whether it survives at half the time.
