Japanese carmakers are moving to cut traditional four- to five-year vehicle development cycles by up to half to counter Chinese competitors that bring new models to market in under two years.

Toyota Motor, Honda Motor, Nissan Motor, Suzuki Motor, and Mitsubishi Motors are overhauling vehicle platforms, cutting part types, and deploying artificial intelligence to speed up product pipelines.

The push targets major operational milestones leading up to 2028, when Nissan plans to launch a vehicle developed under its compressed timeline.

Nissan plans to reduce development lead time for a new sport-utility vehicle intended for North America in 2028 down to three years and one month. The company will then adapt that base platform for derivative vehicles, reducing subsequent model development time by up to 40 per cent to two and a half years.

This family-based vehicle strategy will cover 80 per cent of Nissan’s global vehicle volume. Management expects the common architecture will eliminate 70 per cent of its distinct part types.

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

Honda has rolled out an internal program called Triple Half to halve development expenditures, lead times, and engineering workloads from 2025 baselines. The automaker plans to rely on artificial intelligence and digital design workflows, applying the compressed schedule to vehicle projects that enter development in 2028.

Toyota is targeting manufacturing complexity through a program titled Area 35.
