In EV battle, Toyota bets on new technology and old-school thinking

At factories in Japan's industrial heartland, Toyota (7203.T) has turned to self-propelled assembly lines, massive die casting and even old-fashioned hand polishing as it aims to make up for lost ground in battery electric vehicles.

The world's top-selling automaker believes it can close the gap with Tesla (TSLA.O) and others by combining new technology with the famous lean production methods it has used for decades to wring inefficiency, including excess costs, out of manufacturing.

It also showed off examples of thrifty ingenuity, such as a technique to make high-gloss bumpers without any paint. The mold is hand polished to a mirror finish, giving the bumper its lustre.

TRENDING NOW

Elsewhere, three-decade-old equipment used to process parts can now be run at night and on weekends after being automated through robotics and 3D modeling, improvements Toyota said had trebled equipment productivity.

"The strength of Toyota's manufacturing lies in our ability to respond to changing times," Chief Product Officer Kazuaki Shingo told reporters on the tour.

He pointed to engineering and technology expertise anchored in "TPS", shorthand for the Toyota Production System.

Toyota revolutionised modern manufacturing with its system of lean production, just-in-time delivery and "kanban" workflow organisation. Its methods have since been adopted everywhere from hospitals to software firms and studied widely in business schools and boardrooms around the world.
