Adoption of short-range V2X continues at full steam in China, will take off in Europe in 2027, and is closer to getting the green light in the United States. According to ABI Research, a global technology intelligence firm, more than 10 million vehicles will be capable of short-range V2X communication by 2025. However, indirect communication via the cellular network (e.g., V2N2X, I2N2V) still constitutes the most significant yet untapped V2X opportunity. v2x technology

What Is V2X after all?

The world is full of confusing acronyms, and unfortunately this one a biggie. Vehicle-to-everything, or V2X, is an all-encompassing term for a vehicle’s connected communications. The overall idea is that a vehicle is able, or will be able to, use its on-board communication tools to deliver real-time traffic information, preemptively react to changing road conditions, recognize road signs and warnings, and more. While V2X functions alone won’t be able to manage a vehicle without a driver on board, they are important building blocks in an autonomous vehicle’s ability to piece together a picture of its environment. Within the V2X stable, there are several other “vehicle-to” points of interest.

In 2021, Europe was the region with the largest fleet of short-range V2X communication-enabled cars, but all from a single automaker, Volkswagen. “Given the lack of commitment of more automakers so far, by 2023, China alone will overtake Europe. The inauspicious scenario in Europe is leading industry players to place more emphasis on cellular network tests for the time being. However, there are still fundamental business model challenges to be overcome with this route. Although a truck and a private vehicle OEM may deploy ITS-G5 in 2023, the crucial market driver for mass adoption will be the V2X inclusion in the Euro NCAP scoring, as is currently happening in China. Lagging, the United States now has a solid regulatory framework for C-V2X, paving the way for deployments,” explains Maite Bezerra, Smart Mobility and Automotive Industry Analyst at ABI Research.

Insufficient time to develop new test protocols? V2X technology

There are suggestions in the industry that the V2X inclusion in the 2025 Euro NCAP rating scheme will be delayed to 2027 due to insufficient time to develop new test protocols. This includes establishing enough labs and validating new vehicle capabilities. “If this is the case, it would conveniently coincide with New Radio technologies’ readiness (802.11bd/NR-V2X PC5), meaning that carmakers could ‘skip’ the implementation of existing/legacy radios – provided backward compatibility with current ITS-G5 infrastructure and vehicles is not required. However, it would delay the take-off of the technology even further,” says Bezerra.

While the NCAP has not officially confirmed any changes, there is consensus that if the 2025 timeframe is maintained, it will focus on Day One use cases. There is also consensus that 2027 will be the inflection point for mass adoption because a complete range of Day Two use cases will become part of the Euro NCAP scoring.

C-V2X can be found in low-volume premium vehicle models in China

The recent dismissal of the appeal against the FCC’s 5.9GHz spectrum proceedings means that C-V2X has a clear path in the US and should spur the FCC to grant the existing C-V2X waiver requests faster. On the downside, the US may not have enough spectrum for some advanced cooperative perception/Day 2 use cases in the future. In China, C-V2X is currently found in low-volume premium vehicle models, but there are at least 25 OEMs in different stages of V2X production in the country. COVID-19 lockdowns and discussions about the GNSS positioning standard slowed down deployments in 2022. However, shipments of vehicles with C-V2X will grow exponentially in 2023, surpassing the one million mark as carmakers prepare for China NCAP 2025.

V2X technology has a lot of potential

V2X has significant potential to increase traffic safety, optimize traffic flow, and reduce traffic congestion and emissions. “Therefore, the long wait for mass adoption should not discourage interest in the technology. Instead, it should motivate players to leverage the sizeable installed base of vehicles and infrastructure with embedded cellular connectivity. This will deliver immediate value through basic V2X services that do not rely on low latency and can greatly increase driver awareness scopes, such as road, traffic, traffic-light, and weather hazard alerts and information,” Bezerra concludes. v2x technology
