Formula 1's reputation for mechanical reliability has been shaken in the 2026 season, with a series of technical failures disrupting races. The Canadian Grand Prix, held on the artificial island built for Expo 67, saw multiple retirements due to engine and gearbox issues. Teams that had enjoyed years of trouble-free operation are now grappling with unexpected breakdowns.

Mercedes driver Kimi Antonelli extended his championship lead with a fourth consecutive victory in Canada. The 19-year-old Italian now holds a 43-point advantage over teammate George Russell. With 25 points awarded for a win, Russell faces a deficit equivalent to two race victories, a precarious position when competing with identical machinery.

The weekend was a sprint event, limiting practice time for teams to gather data on their upgrade packages. Several teams introduced new components in Montreal, but not all performed as expected. Reliability problems affected both power unit manufacturers and chassis suppliers, raising questions about the direction of technical development.

Ferrari, which unveiled its new electric vehicle during the race weekend, also struggled with reliability. The team's drivers reported inconsistent power delivery and braking issues during the race. Other midfield teams experienced similar problems, with some failing to finish the 70-lap event.

The trend of reduced reliability marks a departure from recent seasons, where mechanical failures were rare. In 2024 and 2025, the average number of race retirements per event was below three. In 2026, that figure has climbed to nearly five, according to team data.

Drivers have expressed frustration with the situation, noting that races are increasingly decided by reliability rather than driver skill. The Canadian Grand Prix winner, Antonelli, acknowledged that his victory was aided by the retirements of several rivals. He stated that the team is working to understand the root causes of the issues.

Teams are now prioritizing reliability upgrades over performance gains for the next races. The championship battle may hinge on which team can best address these mechanical concerns. The next event, the Austrian Grand Prix, will provide another test of the cars' durability.

Formula 1's governing body, the FIA, has not yet commented on the reliability trend. However, sources indicate that technical directives may be issued to address common failure modes. The 2026 season continues with the Austrian Grand Prix on June 30.

BYD has released a new test video demonstrating the effectiveness of its ultra-fast charging system in extreme cold conditions. The Chinese automaker showcased the Denza Z9GT model achieving a charge from 20% to 97% in just 12 minutes at -30 degrees Celsius.

The test was conducted in a controlled environment simulating severe winter temperatures. BYD's proprietary blade battery technology and advanced thermal management system enabled the rapid charging despite the freezing conditions.

Ultra-fast charging typically faces challenges in low temperatures due to increased internal resistance and reduced chemical reaction rates. BYD claims its system overcomes these limitations through intelligent battery heating and optimized charging protocols.

The Denza Z9GT is an electric luxury sedan under BYD's Denza brand, co-developed with Mercedes-Benz. It features an 800-volt architecture supporting peak charging power of up to 360 kW.

BYD has been expanding its ultra-fast charging network across China, with plans to install thousands of charging stations capable of delivering such high power. The company aims to make long-distance travel more convenient for EV owners.

The test video comes as BYD continues to compete with other automakers in the fast-charging race. Competitors like Tesla and Hyundai have also demonstrated rapid charging capabilities, but extreme cold performance remains a key differentiator.

BYD's blade battery, known for its safety and energy density, is now being adapted for even faster charging without compromising longevity. The company says the battery can maintain high charging speeds across a wide temperature range.

The Denza Z9GT is expected to launch in China later this year, with pricing starting around 400,000 yuan (approximately $55,000). BYD has not yet announced international availability for the model.

A recent study has brought solar-powered cars closer to reality, indicating they could add up to 30 kilometers of range per day. Researchers from multiple institutions analyzed the potential of integrating photovoltaic cells into vehicle surfaces. Their findings suggest that even with current technology, solar energy could meaningfully extend electric vehicle range.

The study examined various factors including geographic location, weather patterns, and vehicle design. In sunny regions, a car covered in solar panels could generate enough energy for 30 km of driving daily. Even in overcast areas, the researchers estimated a gain of 10 to 15 km per day.

Modern solar cells have reached efficiencies above 20%, making them practical for automotive use. The team considered both traditional rooftop panels and newer technologies like transparent solar films for windows. They concluded that a combination of these could cover a significant portion of daily commuting needs.

The research also addressed common concerns about solar cars, such as weight and cost. While adding solar panels increases vehicle weight, the energy generated over the car's lifetime offsets this. The cost of photovoltaic cells has dropped dramatically, making integration economically feasible.

Several automakers have already experimented with solar roofs. Hyundai's Sonata Hybrid and Toyota's Prius Prime offer optional solar panels, though they primarily power auxiliary systems. The new study suggests that with optimized design, solar could directly contribute to propulsion.

The researchers emphasized that solar charging is not a replacement for grid charging but a supplement. For urban commuters driving less than 30 km daily, solar could cover their entire energy needs. This could reduce strain on the electrical grid and lower charging costs.

Practical implementation faces challenges, including panel durability and efficiency in low light. However, the study notes that solar technology is advancing rapidly. Perovskite solar cells, for example, promise higher efficiency and flexibility, which could be integrated into curved car surfaces.

The study was published in the journal Nature Energy. The researchers plan to collaborate with automotive manufacturers to develop prototypes. They estimate that solar-assisted electric vehicles could enter the market within five years, with initial models offering 20 km of solar range per day.

Lexus has unveiled the TZ, marking the brand's entry into the fully electric three-row SUV segment. The vehicle is positioned as a more refined and upscale counterpart to the Toyota Highlander EV, sharing its platform but offering distinct styling and a quieter cabin experience. The TZ is expected to go on sale in late 2024, with pricing starting around $60,000.

The TZ is built on Toyota's e-TNGA platform, which also underpins the bZ4X and the Subaru Solterra.
