Japanese carmaker Honda has joined forces with the General Motors (GM) tech startup Cruise to develop autonomous vehicles as the race to market self-driving cars heats up, the companies announced Wednesday.

Honda’s investment promises broader market access for the new cars once they are ready for the public. The Japanese government hopes to showcase self-driving cars when Tokyo hosts the Summer Olympics in 2020.

With a $2.75 billion commitment in equity and shared development costs over 12 years, Honda joins Japanese conglomerate Softbank in backing the GM venture to create a multi-purpose vehicle that can be manufactured in high volume for use worldwide, the US auto giant said.

Major automakers, start-ups and tech firms are racing to develop truly autonomous vehicles, which the industries see as the next frontier in personal mobility.

Honda’s announcement comes on the heels of Toyota’s move in August to invest $500 million in the ride-hailing service Uber to collaborate on a similar venture to mass-produce self-driving vehicles.

“As is becoming increasingly apparent, this is an effort that requires very, very significant resources to pull off and we’re thrilled to have Honda join forces with us,” GM president Dan Ammann said during an investor call.

Ammann said developers were working “as quickly as we can” to deploy the new technology but did not say when this could occur.

“What we’re giving you here is just an early glimpse of what we think the future looks like,” he said.

The vehicle to be developed with Honda will have no steering wheel or other manual controls when deployed, according to GM.

The race for driverless

With Softbank’s $2.25 billion investment announced in May, Cruise is now valued at more than $14 billion, according to GM.

The company, in which GM now holds an 85 per cent stake, says it is currently testing driverless cars on open roads in Arizona, California and Michigan, “navigating some of the most challenging and unpredictable driving environments.”

Sandy Schwartz, president of Cox Automotive, said the battle to be the first with a driverless product was likely to produce more unexpected partnerships in the coming months.

“I’m a little surprised at seeing bitter rivals joining forces but this is coming. Everybody knows it,” he said.

Combining the strengths of different manufacturers raises the chances of early success, he said.

“You want your partner to be the best partner during that race.”

While fully autonomous vehicles remain a theoretical goal at this point, developing technologies promise swift changes to the market for consumer and commercial vehicles.

The efforts have suffered setbacks especially after some crashes during testing, including a fatality.

Uber briefly suspended tests of self-driving cars in March following a fatal accident in Arizona. It resumed testing in Pennsylvania in July, but with a driver behind the wheel at all times, the company said.

One of self-driving tech firm Waymo’s minivans crashed into a highway median in June, reportedly after its human driver manning the wheel fell asleep.

Ford Motor Company on Tuesday unveiled a proposed standard it said all manufacturers should adopt for vehicles to signal their intentions – like yielding or preparing to stop – to other users of the road.

Ride-hailing service Uber last month also announced it would spend $154 million over five years to expand an existing Toronto laboratory that is developing artificial intelligence for self-driving cars.

The news helped drive shares in GM up 2.1 per cent in New York to $34.00.
