New technology allows car functions to be upgraded wirelessly through software updates, just like in iPhones

SAN FRANCISCO • As cars increasingly resemble digital devices, a group of technology firms that can send wireless software updates to cars are in hot demand by carmakers scrambling to catch up to Tesla Motors in the arena of over-the-air updates, or OTAs.

Interest in the technology, through which certain car functions can be upgraded much the same way as an iPhone, comes as Tesla is set to deliver an OTA for hands-free cruise control this month, allowing its electric Model S sedans to drive themselves on freeways.

Said Strategy Analytics consultant Roger Lanctot: "Tesla has made great strides in raising the profile of OTA, making it appear somewhat sexy by showing how features could be added. They're almost poking the traditional carmakers in the eye by making it look so easy."

That has spurred the big carmakers to get more serious about OTAs, although they are hampered by the challenge of making software compatible with internal combustion engines, dealers worried about losing service revenue and security concerns.

"There's a whole mindset change" as carmakers embrace the need for the technology, said Honda spokesman Matt Sloustcher.

Mr Oren Betzaleli, product strategy head for Israeli OTA firm Redbend, said four years ago it was hard to get in the door. "Today, OTA is so important to carmakers that we can get in right away to see the VPs of manufacturing," he said. He added that between six and 10 car companies are "engaged" with Redbend's technology for cars but declined to name them.

There are about 70 different computers in every modern car, each with software that has to be managed, he said.

Ms Michelle Avary, vice- president of car products and strategy at wireless carrier Aeris, said she had "yet to speak to a single original equipment manufacturer who is not active in this space right now".

The technology has set off a wave of partnerships, investments and acquisitions. Audio products maker Harman International Industries paid US$170 million (S$242 million) to acquire Redbend and another US$780 million to buy Silicon Valley-based Symphony Teleca, another OTA firm. Both deals were in January.

Some big carmakers, including GM, BMW and Mercedes, are already using OTA updates, but mostly for their entertainment systems.

Mr Mahbubul Alam, chief technology officer of Michigan-based global OTA firm Movimento, predicted that in three years, nearly all carmakers will have some kind of OTA capability. Tesla has already introduced more than 75 features via OTA, from raising the ground clearance of cars to boosting acceleration. The recent hacking of a Jeep Cherokee through its telematics system has highlighted security vulnerabilities as cars add more digital technology, and car experts say OTAs are the best way to minimise breaches because weak links can be quickly repaired.

Besides the practical advantages for consumers, who do not need to waste time at dealerships for new fixes, the technology may save money for carmakers because up to half of warranty repair issues and recalls can be corrected through OTAs.

The cost of fixing an issue through a safety recall, in which dealers are compensated for repairs, versus an OTA is higher by a factor of 20 to 30, said Mr Alam, without saying how he arrived at that estimate.

A report last month from research company IHS found that global cost savings from OTAs will grow from US$2.7 billion today to more than US$35 billion in 2022. Those potential savings have eroded earlier resistance to OTAs, said Mr Lanctot. "That's where the chief financial officer says to the chief information officer, 'Get out of the way, buddy, if we don't do this, we're going out of business.'"

As much a tech company as a carmaker, 12-year-old Tesla is free of the constraints its rivals face - complicated combustion engines, huge model ranges, four-year development cycles and a reliance on car dealerships. It "started from a blank piece of paper", said Ms Avary. "They didn't have 100 years of legacy engineering to contend with.

"Your typical combustion engine is still very mechanical. Your gasket blows, it's gone. Tesla is different, they have a lot more software in their cars, it's a very different beast."

Traditional carmakers' reliance on car dealers also impedes OTA adoption, with some dealers worried that their lucrative service revenue will drop off if car owners come less frequently to dealerships when fixes are done by OTA updates, said Mr Lanctot. "It's not in carmakers' interest to annoy the dealer," he said.

Jackson, Michigan, Chrysler dealer Wes Lutz defends his role, arguing that while Tesla's higher- income clients may be tech buffs keen on OTAs, the average car owner is less savvy and needs hand- holding.

"When it's daylight saving time and the clock changes, I have customers lining up out the door," he said.
