Toyota Motor Corp. will reconstruct a capital alliance with Isuzu Motors Ltd., with the two firms investing more than ¥40 billion in each other, in a bid to jointly develop advanced vehicles such as small autonomous trucks.

The revived alliance, announced Wednesday, signals the urgent need for carmakers to find partners in developing new, costly technologies, particularly for automotive electrification.

The alliance, also involving truck-maker and Toyota subsidiary Hino Motors Ltd., aims to clear emissions regulations and meet demand from customers who are increasingly aware of global warming, the companies said.
