In the face of adversities within the autonomous vehicle market, car manufacturers are not hitting the brakes. Rather, they’re zeroing in, adopting more focused and streamlined strategies, deeply rooted in core technologies.

Eager to expedite the mass-scale rollout of Robotaxis, Tesla recently announced an acceleration in the development of their Dojo supercomputer. They are now committing an investment of $1 billion and set to have 100,000 NVIDIA A100 GPUs ready by early 2024, potentially placing them among the top five global computing powerhouses.

While Tesla already boasts a supercomputer built on NVIDIA GPUs, they’re still passionate about crafting a highly efficient one in-house. This move signifies that computational capability is becoming an essential arsenal for automakers, reflecting the importance of mastering R&D in this regard.

HPC Fosters Collaboration in the Car Ecosystem

According to forecasts from TrendForce, the global high-performance computing(HPC) market could touch $42.6 billion by 2023, further expanding to $56.8 billion by 2027 with an annual growth rate of over 7%. And it is highly believed that the automotive sector is anticipated to be the primary force propelling this growth.

Feeling the heat of industry upgrades, major automakers like BMW, Continental, General Motors, and Toyota aren’t just investing in high-performance computing systems; they’re also forging deep ties with ecosystem partners, enhancing cloud, edge, chip design, and manufacturing technologies.

For example, BMW, who’s currently joining forces with EcoDataCenter, is currently seeking to extend its high-performance computing footprint, aiming to elevate their autonomous driving and driver-assist systems.

On another front, Continental, the leading tier-1 supplier, is betting on its cross-domain integration and scalable CAEdge (Car Edge framework). Set to debut in the first half of 2023, this solution for smart cockpits offers automakers a much more flexible development environment.

In-house Tech Driving Towards Level 3 and Beyond

To successfully roll out autonomous driving on a grand scale, three pillars are paramount: extensive real-world data, neural network training, and in-vehicle hardware/software. None can be overlooked, thereby prompting many automakers and Tier 1 enterprises to double down on their tech blueprints.

Tesla has already made significant strides in various related products. Beyond their supercomputer plan, their repertoire includes the D1 chip, Full Self-Driving (FSD) computation, multi-camera neural networks, and automated tagging, with inter-platform data serving as the backbone for their supercomputer’s operations.

In a similar vein, General Motors’ subsidiary, Cruise, while being mindful of cost considerations, is gradually phasing out NVIDIA GPUs, opting instead to develop custom ASIC chips to power its vehicles.

Another front-runner, Valeo, unveiled their Scala 3 in the first half of 2023, nudging LiDAR technology closer to Level 3, and laying a foundation for robotaxi(Level 4) deployment.

All this paints a picture – even with a subdued auto market, car manufacturers’ commitment to autonomous tech R&D hasn’t waned. In the long run, those who steadfastly stick to their tech strategies and nimbly adjust to market fluctuations are poised to lead the next market resurgence, becoming beacons in the industry.

Toyota announced during a technical conference on June 13, 2023, that Toyota has identified suitable materials to commercialize solid-state battery technology around 2027-2028, intending to introduce new energy vehicles powered by these batteries to the market.

Out of the 2.17 million electric vehicles (including BEV, PHEV, HEV, FCV) sold by Toyota in 2022, BEVs accounted for less than 1%, indicating a significant lag behind its competitors in the BEV sector. However, Toyota possesses over 100 solid-state battery patents and showcased a solid-state battery prototype as early as 2020, finally catching up in the solid-state battery race.

According to TrendForce’s analysis, current new energy vehicles primarily use nickel-cobalt-manganese (NCM) or lithium iron phosphate (LFP) as cathode materials, and graphite as anode material. NCM batteries offer higher energy density, with a system limit of around 250-260Wh/kg, but come with higher costs and a risk of thermal runaway. On the other hand, although LFP batteries are safer, less prone to thermal runaway, and more cost-effective, their energy density is significantly lower than that of NCM, with a system limit of approximately 160-170Wh/kg.

To achieve energy densities surpassing 300Wh/kg and reaching the 400-500Wh/kg target, lithium batteries will primarily focus on adjusting anode materials in the future. This includes incorporating higher-capacity materials such as silicon oxide, silicon carbon, or metallic lithium to increase the capacity of individual battery cells. However, using these high-activity anode materials in combination with traditional liquid electrolytes carries a higher risk of triggering thermal runaway during the charging and discharging processes.

In contrast, solid-state electrolytes provide structural stability, effectively preventing short circuits in batteries. By removing the separator film, solid-state batteries achieve a more compact size and higher energy density compared to liquid lithium batteries. In summary, solid-state batteries solve the challenge of balancing safety and energy density that traditional lithium batteries face, making them the most promising battery solution for future new energy vehicles.

However, during the development of solid-state battery technology, Toyota encountered an increase in interface impedance and a decrease in electrode-electrolyte adhesion due to the transition from liquid to solid electrolytes. These issues lead to battery capacity decline and affect cycle life, posing one of the many technical challenges in the current development of solid-state batteries.

Considering the difficulties involved, some battery manufacturers have shifted their focus to semi-solid-state batteries, such as CATL and Welion. Given Toyota’s current reliance on Chinese liquid battery technology for their development of solid-state batteries, it seems like a formidable task to achieve a breakthrough. Even if they overcome these challenges, the ability to replicate the success from the lab to actual vehicles remains uncertain.

Nevertheless, considering Toyota’s current situation, it may be more reasonable to place their bet on solid-state batteries rather than persistently chasing after the liquid battery sector. Although this strategic move carries high risks, it represents Toyota’s best and potentially last opportunity for overtaking competitors in the new energy vehicle field.

Since the 1980s, Toyota collaborated with Denso to conduct research on SiC. In 2014, SiC inverters were installed in Toyota’s Prius and Camry hybrid electric vehicles (HEVs) for driving and on-road testing, confirming a 5-10% improvement in energy efficiency. After this successful testing, Toyota adopted SiC in its hydrogen fuel cell buses that were put into formal operation in 2015 and 2018. At that time, the cost of SiC chips was higher than it is now, so Toyota continued to primarily use Si-IGBT inverters in its hybrid vehicle models.

Model 3 SiC Inverter Sparks Toyota’s Concerns About Electrification

In 2017, the Model 3, equipped with SiC inverters, became the best-selling battery electric vehicle (BEV) on the market due to its high performance and long range. It also contributed to the surge of new BEV sales, which exceeded 1.2 million vehicles in 2018. Since then, many automakers have targeted SiC as the basis for next-generation BEV drivetrain systems, while Toyota continued to adhere to its hybrid electric vehicle (HEV) and hydrogen fuel cell vehicle (FCV) strategies. According to TrendForce, the total new sales of PHEVs and BEVs is estimated to reach approximately 10.63 million vehicles in 2022, while Toyota’s sales in this sub-market are only close to 100,000, accounting for about 1% of the market share, far behind BYD’s 19% and Tesla’s 15%.

In the current EV industry, BEVs and PHEVs have become the mainstream, while HEVs may gradually shrink in the future market. Pressures from the changing market have forced Toyota, which has not fully focused on BEVs and PHEVs in the past, to rethink its overall electrification strategy and accelerate the production capacity and technological layout of key components, such as SiC.

Toyota aims to sell 3.5 million electric vehicles by 2030, and has demonstrated its commitment to electrification through the establishment of a SiC wafer manufacturing technology research company. SiC chips have the potential to improve energy efficiency in electric vehicles, but their high cost is currently a challenge due to low SiC wafer yields in the manufacturing process. QureDA Research’s Dynamic AGE-ing technology could help improve wafer yields and lower chip costs. If successful, this technology, combined with Toyota’s market presence, could enhance the competitiveness of Toyota’s electric vehicles and give them a chance to compete for a leading position in the future electric vehicle market.

According to TrendForce data, total sales of new energy vehicles (NEVs including battery electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles) in 1Q22 was 2.004 million units, an annual growth rate of 80%. Battery electric vehicles (BEV) demonstrated the strongest growth with sales reaching 1.508 million units. Plug-in hybrid electric vehicles (PHEVs) sold 493,000 units. Growth in NEV sales did not come easy, as global auto market sales (regardless of powertrain type) fell by 7% YoY in 1Q22 due to factors such as the chip shortage, Russian-Ukrainian war, and China’s pandemic lockdown and prevention measures.

In terms of BEV brands, Tesla’s sales in 1Q22 exceeded 310,000 units, ranking first with a market share of 20.5%. Chinese automaker BYD ranked second with 143,000 units and a market share of 9.5%. BYD announced in April that it would stop producing fossil-fueled vehicles and transform fully into a NEV manufacturer. Its BEV sales rose sharply by 271% in 1Q22 compared to the same period last year. Wuling, a subsidiary of SAIC-GM, has been ranked second since the launch of the Wuling Hongguang MINI in 2020 but dropped to third place in 1Q22. The main contributor to this was the multitude of models positioned as miniature and low-priced launched in the past year such as the Chery Ant and Changan Benben. As similar products arrived on the market, sales competition hindered growth.

In terms of PHEVs, BYD once again broke its quarterly sales record. Sales volume in 1Q22 reached 142,000 units, with a market share of 28.8%. As more PHEV models gradually appear in the market, it has become increasingly more difficult to capture a large market share. It is worth noting that the sales volume of PHEVs in the European market was lower in 1Q22 both when compared with the same period last year and when compared to 4Q21, affected the performance of some European brands.

TrendForce expects that most automakers will adopt a strategy of prioritizing the production of EVs. Therefore, continued growth in the sale of NEVs is expected in 2022. However, automakers will be under greater cost pressure this year. In particular, the Russian-Ukrainian war has greatly increased the cost of power batteries. This has caused automakers to increase their prices. Some countries including China will withdraw car purchase subsidies which dampens the market for low-priced mini-cars that previously supported the rapid growth of NEVs. Factors such as global inflation will become variables in the future growth momentum of NEVs.

Due to the Russian-Ukrainian war, automotive factories currently located in Russia have shut down successively and stopped importing vehicles, TrendForce asserts. In addition, Russia has stated that if foreign-funded enterprises choose to permanently suspend business or withdraw from the market during this period, the Russian government will nationalize their business assets. Most automotive brands have factories in Russia and now face the dual pressures of international public opinion and corporate losses. According to TrendForce investigations, after Renault-Nissan acquired the Russian brand LADA, its market share reached 32%, making it the largest automotive brand in Russia followed by Hyundai-Kia at 23% and Volkswagen at 12%.

According to TrendForce, since Renault is the largest shareholder of local automaker AVTOVAZ and Russia is the company’s second largest market, whether AVTOVAZ is nationalized or sales are lost, the overall impact on Renault cannot be underestimated. In addition, even if production can continue, the depreciation of the ruble will greatly increase the cost of importing components.

Soaring costs not conducive to automotive industry recovery

The large number of components and the long supply chain inherent in the automotive industry makes mitigating geopolitical risk difficult. Almost all international or regional events will affect the normal operation of this industry. The Russian-Ukrainian war will not only affect automaker assets, supply chains, sales, and revenue in Russia and around the world in the short term but, in the long term, geopolitics will influence business planning, competiveness, and technology options. More broadly, geopolitical and economic conflicts are derailing automakers’ plans to recover from the pandemic and chip shortages.

According to TrendForce, there are three major factors impeding the recovery of the automotive industry and these factors will further affect automobile sales in 2022. First, the production of vehicle components in Ukraine has halted, affecting the production of complete vehicles. Volkswagen indicated that it intends to move production capacity to North America and China due to the shortage of vehicle wiring harnesses. Second, Russia produces various upstream raw materials such as nickel and palladium for vehicle manufacturing. Due to supply constraints, various costs have risen sharply and some car manufacturers have begun to increase the price of complete vehicles. Third, inflationary pressures have risen sharply, leading to rising costs of living and a reduction of consumer spending power.
