On June 16th, the Chongqing-Chengdu intercity transit event for the Deep Blue S7 was successfully held. The event was led by senior executives from Changan Automobile, in collaboration with product engineers and industry experts. Through continuous live streaming, they provided an online analysis of the Deep Blue S7's super range extension technology.

It is understood that the Deep Blue S7 is currently in the pre-order stage, with the official pre-order starting price for the range-extended version set at 169,900 yuan. There are currently two models available, with pure electric ranges of 121km and 200km under CLTC conditions, and a maximum combined range of up to 1,120km.

The core competitiveness of the Deep Blue S7 range-extended version comes from Changan Automobile's super range extension technology. This technology has three major highlights: "pure electric drive," "long range," and "low energy consumption."

The Deep Blue S7 range extension technology features three key range extension highlights: pure electric drive, long range, and low energy consumption. The so-called pure electric drive means that the engine operates imperceptibly across the entire range, providing a thousand kilometers of pure electric quiet enjoyment. The Deep Blue S7 range extension technology employs four core technical strategies: NVH intelligent balance strategy, engine imperceptible start strategy, full-scenario low-torque vibration structure design, and howling frequency conversion active control technology, to bring users a driving experience that is as quiet, smooth, vibration-free, and imperceptible as a pure electric vehicle under all conditions and scenarios.

It is worth mentioning the engine imperceptible start strategy, which means that the engine can start and stop silently and generate power imperceptibly, providing a smooth and imperceptible driving pleasure throughout the journey, just like a pure electric drive. In addition, the howling frequency conversion active control technology precisely controls the switching frequency of the range extender generator, reducing vibration noise caused by high-frequency vibrations, further optimizing the quiet and imperceptible experience of the entire vehicle.The Deep Blue S7's extended-range mode offers a driving range of 1120km, meeting the needs for long-distance travel without the need to search for charging stations along the way, just refuel and go. It combines the advantages of pure electric and fuel-powered vehicles, offering both extremely low operating costs and solving various issues such as range anxiety and inconvenient charging associated with pure electric models. With technological innovations such as high compression ratio and deep Atkinson cycle, the generator achieves a maximum efficiency of 96%, and under CLTC conditions, it can generate approximately 3.3 kWh of electricity per liter of fuel. Even in a depleted battery state, the Deep Blue S7 still boasts a fuel consumption as low as 4.95L/100km, leading the industry in its class.

In terms of low energy consumption, under CLTC conditions, the Deep Blue S7 has an impressive pure electric range of 200km, not only meeting the needs for environmental protection and low-carbon daily commuting but also significantly reducing operating costs, allowing for a month without refueling and a week without charging. With technological innovations such as high compression ratio and deep Atkinson cycle, the Deep Blue S7 has achieved a generator efficiency of up to 96%, and under CLTC conditions, it can generate approximately 3.3 kWh of electricity per liter of fuel. Even in a depleted battery state, the Deep Blue S7 still boasts a fuel consumption as low as 4.95L/100km, leading the industry in its class.

In extended-range mode, the Deep Blue S7's total driving range can reach 1120km, satisfying users' needs for long-distance travel. And even in a depleted battery state, the Deep Blue S7 still boasts a fuel consumption as low as 4.95L/100km.

It is worth mentioning that the Deep Blue S7 is born from the EPA1 all-electric digital platform, which has four major technological characteristics: high efficiency, high performance, high intelligence, and high safety. It is compatible with various power forms such as pure electric, extended-range, and hydrogen electric, meeting users' needs for all-scenario travel.

Changan Automobile has also endowed the Deep Blue S7 with rear-wheel drive genes and a nearly 50:50 front-to-rear axle weight distribution, equipped with a rear H-arm type multi-link system. While possessing the driving quality of pure electric products, it also has the driving pleasure of rear-wheel drive models, fully satisfying individuals' pursuit of driving fun.

At the current stage where new energy vehicles and traditional fuel vehicles are advancing side by side, the Deep Blue S7 not only addresses users' various doubts about new energy vehicles but also, with the support of multiple technologies such as NVH intelligent balancing strategy, full-scenario low-torque vibration structure design, engine imperceptible start strategy, and howling frequency conversion active control, it helps to overturn users' perception of new energy vehicles. At the same time, the Deep Blue S7's inherent rear-wheel drive genes can make the driving pleasure exceed expectations.
