Changan Suzuki Tianyu SX4 is a brand new family sedan, which integrates many advantages of SUVs, not only has strong passing ability, but also has a tall body, wide tires, and large wheels, which is not an ordinary family sedan at first glance. Because of the high fuel consumption of SUVs, the Tianyu SX4 caused people to worry about its fuel consumption at the beginning of its launch. However, judging from the sales volume three years ago, the fuel consumption of Tianyu SX4 is not high, but it has been widely recognized in terms of energy saving.
Practice has proved that Tianyu SX4 is indeed very fuel-efficient.
Anyone who has used it knows that even in the metropolis, the Tianyu SX4 can drive to about 8 liters, and the average fuel consumption of many people is only 7 liters. This performance has far surpassed the family cars of the same class, and even surpassed the fuel economy of the Corolla and Civic. Such a stark contrast has made many Tianyu SX4 owners have questions, and many people are discussing, how can Tianyu SX4, a model that does not seem to be a "fuel-efficient car", consume so little fuel?
Excellent powertrain design is key.
The Changan Suzuki Tianyu SX4 is equipped with an M16 engine, which looks like most models in the same class, made of aluminum alloy and equipped with VVT variable valve timing, but no one knows that there are so many secrets hidden in it. How well an engine performs is not determined by the technology we are familiar with, but by its design. Many cars that look like they're tech-efficient aren't actually fuel-efficient, and that's the secret. For example, the precision of engine design, processing, and assembly will have a direct impact on the operating resistance of the engine. There is also the accuracy of fuel injection, the more fuel injection, the greater the fuel consumption, the less injection, the weaker the power of the engine, and the amount of fuel injection, but also affected by many factors such as speed, load, temperature, etc., so there must be a set of accurate calculation and control procedures. All of this is a great test for an engine engineer.
And in this regard, it is Changan Suzuki's strength. Suzuki made motorcycles in the earliest days. Motorcycles have high requirements for engines, so Changan Suzuki has a strong accomplishment in engines. This should also be felt by our domestic consumers. As early as the end of the last century, all models under Changan Suzuki were equipped with all-aluminum alloy engines, which could be said to be unique in China at that time. These foundations are used in the design of the engine, and fuel consumption is one aspect.
A good match is also important.
Anyone driving the Changan Tianyu SX4 can feel the power of this engine at low speeds, and at the same time, they can also feel its smoothness. And this is another secret of the Skywhisper SX4's fuel saving.
At 2000 rpm, the Changan Suzuki M16 engine burst out with maximum torque. This feature not only makes the driver feel relaxed when driving in normal times, but also automatically shifts gears and reduces fuel consumption because of sufficient power. Don't underestimate the speed of the engine, every time it is doubled, the frequency of the engine will be doubled, and the number of injections will also be doubled, which has a great impact on the overall fuel consumption of the car. When the driver uses it incorrectly, the ECU can correct the operation through the electronic throttle, which also includes financial compensation.
And all of this thanks to this game. The drivetrain adopted by Changan Suzuki on the Tianyu SX4 can be described as a perfect match. Tianyu SX4 is smaller than the average family car in terms of gear ratio in fourth and fifth gears, and the difference in gear ratio between different gears is also relatively large. At high speeds, a smaller gear ratio is beneficial for reducing rotational speed at higher speeds and reducing fuel consumption. Such a large tooth pitch difference is also thanks to the wide torque platform provided by the Tianyu SX4 engine. In fact, the two go hand in hand. Chang'an Suzuki's technicians have finally achieved today's results through continuous testing, continuous debugging, and continuous matching. The ultimate goal is to combine power and economy perfectly.
This is not only the matching of the powertrain, but also the adjustment of the chassis, the design of the body, and the configuration of the tires. Especially the tires. Many people have discovered that the tires of Changan Tianyu SX4 are not produced in China like other manufacturers, but use the same Yokohama tires as the overseas version. In fact, there's a reason for that. Judging from the size, pattern and material of the tires, Changan Suzuki and Suzuki have made corresponding adjustments, which can not only improve the grip of the tires, but also improve the economic performance of the vehicle.
The performance of a car depends on various factors, including fuel consumption. This is not just engine technology, nor is it a special design, but an improvement in all aspects. The reason why the Tianyu SX4 can surprise people is because of Changan Suzuki's strong automobile manufacturing strength. In fact, not only the Tianyu SX4, but every car in Changan Suzuki is notoriously fuel-efficient, but the Tianyu SX4 is a very conspicuous cross.
