Between Chery and Changan, Chery has slightly lower fuel consumption. Transmission impact on fuel consumption: The transmission is a power-speed regulation device connected between the engine output and the wheel drive shaft. Its basic functions are: changing the corresponding "power-speed" combination according to driving needs, altering rotation direction (reverse gear), and disconnecting the engine from the drive shaft (idle). Vehicle weight impact on fuel consumption: The heavier the vehicle body, the more power is required, naturally leading to higher fuel consumption. Design factors affecting fuel consumption: Primarily refers to the drag coefficient. Body design isn't just about aesthetics but also considers the drag coefficient. The more streamlined and smoother the car design, with smaller body attachments, the more effectively wind resistance can be reduced. A lower drag coefficient means less wind resistance, better stability, and improved fuel efficiency. Generally, a 10% reduction in drag coefficient can decrease fuel consumption by 3%.

To be honest, this issue really can't be generalized. I've helped friends compare data on many models, and the fuel consumption between Chery and Changan's vehicles in the same class is actually quite similar. For example, the Tiggo 8 and CS75 PLUS both have a combined fuel consumption of around 8-9 liters per 100 km in real-world driving. The key is which model you choose—smaller displacement engines like the 1.5T are definitely more fuel-efficient than the 2.0T, and manual transmissions usually save about 1 liter compared to automatics. I recently drove Chery's Tiggo 7, and the dashboard showed just 6.8 liters per 100 km during highway cruising, but it shot up to 10 liters in traffic jams. Changan's new Blue Core engines have indeed optimized fuel economy, but it still depends on actual driving habits—aggressive acceleration and braking can easily add 2-3 liters to your consumption.

Last week, I helped my father-in-law choose a car and specifically visited four or five dealerships to compare fuel consumption data. I found that among compact SUVs, the Chery Tiggo 5x has an urban fuel consumption of around 8L, while the Changan CS55 PLUS is about 8.2L—the difference is negligible. However, it's important to note that vehicle weight plays a significant role; Changan models are generally about 50kg heavier, equivalent to carrying an extra child. Additionally, there's a noticeable difference in transmission tuning: Changan's AT transmission shifts more smoothly in traffic but is slightly less fuel-efficient, whereas Chery's CVT is more economical at a steady 70 km/h. My advice is to focus on asking about the curb weight when checking out cars and to watch the instant fuel consumption gauge for ten minutes during a test drive—it's far more reliable than listening to sales pitches.

I specifically checked last year's fuel consumption report from Autohome. In the compact car category, the Chery Arrizo 5 automatic transmission model consumes 7.2L per 100km, while the Changan Yidong DT requires 7.5L. However, when it comes to mid-size SUVs, this gap reverses. Hybrid models show particularly noticeable differences, with the Changan iDD achieving a measured fuel consumption of 4.3L, significantly lower than Chery's plug-in hybrid at 5.1L. In fact, tires have a greater impact than imagined—switching to low rolling resistance tires can save 0.8L per 100km. Hot weather with air conditioning directly increases fuel consumption by 15%, and these factors are far more critical than brand differences. Ultimately, it's about specific configurations rather than just comparing car badges.

My friend recently bought a Changan UNI-T, while I drive a Chery Tiggo 8. We often swap cars to conduct fuel consumption tests. During morning and evening rush hours in the city, the Changan shows 9.2 L/100km, and the Chery shows 9.0 L/100km. However, when cruising at 110 km/h on the highway, the Changan is actually 0.3 L/100km lower. An interesting observation: the Chery's start-stop system is quite aggressive, which saves some fuel at red lights, but the frequent restarts can be annoying for some people. The Changan's driving mode adjustment is smarter, with its Eco mode able to keep the RPM very low. New cars generally have higher fuel consumption during the break-in period, but it typically drops by about 0.8 L/100km after running over 5,000 km. If fuel efficiency is a top priority, considering a hybrid version is recommended.
