The official combined fuel consumption of the Oshan X7 is 7.4L per 100km. Below is relevant information about the Oshan X7: 1. Brand: The Oshan X7 is a new compact SUV under Oshan. The new vehicle originates from Changan's global R&D center's new modular MPA-2 platform, which has the capability to develop products with three energy forms: EV, hybrid, and traditional fuel vehicles. 2. Design: The Oshan X7 adopts a natural aesthetic design with aerospace-level painting technology. It features a large hexagonal front grille with wave-pattern horizontal bars extending downward on both sides. The Changan Oshan Cloud Eagle logo is suspended above the grille, giving the overall design high recognition. In terms of exterior configurations, it comes with full LED natural light compound headlights and dual-color straight-cut alloy wheels.

I drive the Oshan X7 1.5T automatic transmission version myself, mostly commuting in the city on a daily basis, with fuel consumption fluctuating between 9.5 to 11 liters per 100 kilometers. On long highway trips, it drops to around 7.5 to 8.5 liters, which isn’t considered high—SUVs naturally consume more fuel than compact cars, but they offer greater space and practicality. The vehicle’s weight has a noticeable impact; when fully loaded with family or luggage, fuel consumption can spike above 12 liters. I’m used to driving in eco mode with smooth starts, avoiding sudden acceleration and braking, which helps me squeeze an extra few dozen kilometers out of each tank. The monthly fuel cost of around 400-500 RMB is still manageable. I recommend regularly checking tire pressure and the air filter—maintaining proper tire pressure can save about 5% in fuel consumption. If you frequently encounter city traffic jams, considering the hybrid version might be more cost-effective. The Oshan X7’s fuel efficiency is average among compact SUVs.

The fuel consumption of the Oshan X7 is primarily determined by the engine and transmission system. The 1.5T Blue Whale engine delivers stable power output, and when paired with the 7-speed dual-clutch transmission, it achieves high transmission efficiency. The official combined data from the Ministry of Industry and Information Technology is 8.8 liters per 100 kilometers. In actual use, transmission responsiveness and driving modes have a significant impact on fuel consumption. Switching to Sport mode can increase fuel consumption by 1 to 2 liters. Insufficient tire pressure or overloading with a roof rack increases resistance, while maintaining a speed of 100 km/h during highway cruising can balance wind resistance and reduce fuel consumption to as low as 7 liters. Regular oil changes ensure proper engine lubrication, and the power consumption of the air conditioning compressor can also raise fuel consumption. I have monitored different road conditions using the onboard computer: fuel consumption drops below 6 liters on downhill sections but rises to 10 liters on uphill stretches, highlighting the importance of balanced driving habits.

The Chang'an Oshan X7 typically has a combined fuel consumption of 9-11L/100km, reaching 10-12L in congested urban areas and 7-9L on highways during long-distance trips. The 1.5T engine offers moderate power but consumes slightly more fuel compared to smaller-displacement engines. Owners report that the manual transmission version saves about 1L/100km. Its spacious interior is practical, though the added weight increases fuel consumption. Driving in Eco mode can keep consumption below 9L/100km by avoiding sudden acceleration and braking. Fuel efficiency is slightly higher during the initial few thousand kilometers of the break-in period but stabilizes after 10,000km. Overall, it's suitable for family use—not particularly fuel-efficient but average for its SUV class.

Fuel consumption largely depends on your driving habits. I tested the Oshan X7 in both urban and highway conditions, and the difference was significant. In city traffic with frequent stops and starts, fuel consumption rose to 12L/100km, but on the highway with cruise control set at 80km/h, it dropped to around 7L/100km. Driving style is crucial—each sudden acceleration burns an extra 0.5L of fuel, so it's advisable to start smoothly and anticipate traffic lights. Air conditioning also has a noticeable impact: summer cooling increases consumption by about 1L, while winter heating has a slightly lesser effect. Good habits, like changing engine oil every 5,000km and checking tires, are essential—just 0.1bar lower tire pressure can raise consumption by 0.3L. The Oshan X7 has a 55L fuel tank, and adopting smoother driving habits can extend your range by 50km per tank, saving money and being eco-friendly.

The fuel consumption of Oshan X7 varies significantly under different conditions. On flat highways at 110km/h, it's about 8L/100km, dropping to as low as 6L on downhill sections, but can surge to 12L when climbing or during peak urban traffic. Compared to similar SUVs like the Haval H6, the fuel consumption is roughly the same at around 9L, but about 2L more than sedans. The impact of load is not negligible, with a full load of five people plus luggage increasing fuel consumption by over 10%. Rainy conditions with slippery roads and increased tire resistance also slightly raise fuel usage. On several long trips with moderate air conditioning, the fuel consumption averaged about 9L. Using the cruise control system helps maintain steady speed and save fuel, while adjusting tire pressure seasonally accommodates temperature changes.
