On July 1, we learned from the Buick brand official that Zhiguang L7 launched a new energy "worry-free double insurance", which includes spontaneous combustion and car damage-free. It is worth mentioning that the "Safety Requirements for Power Batteries for Electric Vehicles" (GB38031-2025) (hereinafter referred to as the "New National Standard for Batteries") has been formally implemented from today, adding harsh tests such as fast charging cycles and bottom impact. Specifically, look at the official "Worry-Free Double Insurance", which includes spontaneous combustion within 8 years or 160,000 kilometers. If the tram spontaneously combusts due to the quality problem of the three-electric system and meets the national motor vehicle scrapping standards, you can enjoy the "spontaneous combustion" rights and compensation and other values of new cars provided by the manufacturer; while the car damage is worry-free, users can also choose to purchase the "gold and stone contract" protection service for major car damage "only in exchange for no repair". Within 3 years, the single accident car damage exceeds 30% of the purchase fare, and you can also enjoy the free replacement of new car rights. Simply reviewing the appearance of the vehicle, the Buick Transit L7 adopts the styling design concept of the concept car ELECTRA-L, and adopts the Buick family design language with the star spreading wing headlight group and the active intake grille, which has a good visual recognition as a whole. In terms of dimensions, the length, width and height are 5032/1952/1500mm and the wheelbase is 3000mm. At the same time, the first L7 to the border is equipped with the "Xiaoyao Zhixing" assisted driving system based on the Momenta R6 flywheel model, which is the first to provide leading functions such as "No Breakpoint City Noa" and "All Types of Parking Assistance", which can accurately identify complex road conditions. Inside, the car features a wrap-around design with a 10.25 -inch all-LCD meter, a 15.6-inch center control screen, and a 50-inch panoramic AR-HUD head-up display. The vehicle will be equipped with Qualcomm's latest-generation SA8775P chip with the Adreno 663 graphics processing unit, which has 72 tops of NPU neural computing power. In terms of power, the Buick Frontier L7 will use the 1.5T engine model LD3 produced by SAIC General Motors as the range extender, with a maximum power of 115 kW, a peak torque of 230 Nm, and a maximum drive motor power of 252 kW. Its 0-100km/h acceleration time is 5.9 seconds, and the combined fuel consumption is as low as 0.5L/100km. At the same time, the Buick Frontier L7 is equipped with a full-stack self-developed range extension system, which uses a newly developed 40.2kWh Allen battery. The CLTC has a pure electric range of 302km and a comprehensive range of more than 1400km. (Wen/Auto Home Zhou Yi).
