Is the 2021 All-New Besturn B70 Fuel-Consuming?

[AbigailDella]

2021 All-New Besturn B70 has a fuel consumption ranging between 6.1L-9.4L. It is not very fuel-consuming. Here is some information about fuel consumption: 1. Introduction: Generally refers to the amount of gasoline consumed by a car per 100 kilometers, which is a theoretical indicator of the vehicle. 2. Methods to Reduce Fuel Consumption: The longer the idle parking time, the greater the fuel consumption, so try to minimize idle parking time; avoid rapid acceleration, slamming the throttle, and driving at lower engine speeds. 3. Factors Affecting Fuel Consumption: Various working conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, temperature, and whether the air conditioning is on, all have an impact. 4. Calculation of Fuel Consumption: Fuel consumption per 100 kilometers = volume of a certain amount of fuel (liters) ÷ distance the car can travel with that amount of fuel (kilometers) × 100.

I've been driving the Bestune B70 for almost half a year now, and the 1.5T version does drink a bit more fuel in city commuting. During morning and evening rush hours with heavy traffic, the dashboard shows fuel consumption fluctuating between 9.2 to 10.5 liters per 100 km, and it can even jump to 11 liters when using AC in summer. However, it's quite a pleasant surprise on highway drives during weekends - maintaining 100 km/h cruise control brings it down to around 6.8 liters. Just a heads-up: while the 55-liter fuel tank isn't small, you'll find yourself refueling more frequently than Japanese cars with the same displacement if you often drive in stop-and-go traffic with many traffic lights. I'd recommend installing a fuel consumption tracking app to record refueling data for more accurate measurements.

According to official specifications, the Bestune B70 has a WLTC combined fuel consumption of 6.8L/100km. However, in actual driving, I found the engine tuning to be sporty-oriented. When the turbo kicks in at 2000 rpm, the power delivery becomes quite aggressive, at the cost of instantaneous fuel consumption surging to 15L when flooring the accelerator. Remember to maintain tire pressure above 2.4Bar - I once experienced a 0.7L/100km increase when tire pressure was insufficient. Carrying excess cargo in the trunk also adds burden; after one camping trip when I didn't unload equipment, urban driving consumed an extra half liter. Those who upgrade to larger wheels should be especially cautious - 19-inch wheels consume at least 5% more fuel than the stock 17-inch tires.

After repairing several B70 models, it was found that abnormal fuel consumption is often related to three issues: First, a stuck carbon canister purge valve can steal fuel, with symptoms of a strong gasoline smell; second, carbon buildup on the oxygen sensor leads to inaccurate fuel injection; and third, delayed maintenance, especially using the wrong oil viscosity—5W-30 is more fuel-efficient than 40. One particularly typical case involved a owner complaining about 13 liters per 100 km, which turned out to be caused by a seized brake caliper. It is recommended to clean the throttle body every 20,000 kilometers. For those who frequently drive short distances, pay attention to the battery charge—when the voltage is insufficient, the alternator will burn excessive fuel to recharge.

As someone who drives the B70 daily for business, the fuel consumption fluctuates more than I expected. In winter, warming up the car for five minutes plus using the seat heating increases the one-way fuel consumption by 1.3L compared to spring and autumn. Using cruise control on expressways saves a lot, with 80 km/h being the most economical. However, the most mysterious factor is the fuel type. Using 92-octane fuel results in softer power and higher consumption, while switching to 95-octane saves me 60 yuan per month on the same route. Once, I was in a hurry and used sport mode on the highway, which increased fuel consumption by 2.1L compared to eco mode. Now in summer, I remotely start the air conditioning via my phone in advance, which is much more fuel-efficient than cooling down the car while idling.

Having tested over thirty domestic B-segment sedans, the B70's fuel consumption ranks in the middle. Its 1.5T engine boasts a decent thermal efficiency of 39%, but the 7-speed dual-clutch transmission still exhibits some jerky and fuel-consuming behavior at low speeds. One often-overlooked detail: when the auto start-stop is activated, each restart consumes fuel equivalent to 0.7 seconds of idling. It's only cost-effective for traffic lights exceeding 60 seconds—for my urban commute, turning it off actually saves more fuel. Those cameras on the side mirrors aren't just for driver assistance; they automatically detect inclines to pre-adjust fuel injection, saving about 0.4L/100km on mountain roads compared to models without this feature.
