What is the fuel consumption of the A45?

[RhettMarie]

Generally speaking, the fuel consumption of a Mercedes-Benz AMG sedan is considered normal within the range of 8-15 liters per 100 kilometers. The specific fuel consumption also depends on the vehicle's condition, road conditions, and the driver's habits. Car fuel consumption varies slightly depending on each individual's driving habits and skills. More stable driving habits result in lower fuel consumption, while frequent aggressive driving, overtaking, and other high-revving operations will appropriately increase fuel consumption. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance will require increasing the fan speed and lowering the temperature to achieve a cooling effect. 2. Frequent sudden braking: Frequent sudden braking is a primary reason for persistently high car fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive air conditioning in small-displacement cars: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after entering. First, open the windows and set the fan to a higher setting without turning on the air conditioning to expel the hot air inside. After the vehicle has cooled down moderately, then turn on the air conditioning.

As an A45 owner who drives it regularly, I think fuel consumption really depends on how you drive. My daily commute involves a lot of congested urban roads, averaging around 9L/100km overall. In city driving, it can jump to 11L, while on highways maintaining steady speeds can bring it down to about 7.5L. With its AMG high-performance engine, this car delivers fierce power but has a hearty appetite—it's definitely thirstier compared to regular family cars. Many factors affect consumption: AC usage spikes fuel burn, and winter engine thermal efficiency drops slightly. After years of ownership, I've learned that gentle throttle inputs and avoiding sudden acceleration can save a liter or half-liter. Ultimately, if you're after driving excitement, don't obsess over fuel costs—but do maintain air filters and spark plugs properly for long-term savings and reliability.

Speaking of the AMG A45, fuel consumption varies from person to person. Mine is the 2019 model, with an official combined figure of 9.5 liters per 100 kilometers, but in reality, I get just over 10 liters in the city and below 8 liters on the highway—which is normal, considering the strong burst of power from the 2.0T turbocharged engine. The exhilarating acceleration comes at the cost of a rapidly dropping fuel gauge. There are many factors at play: aggressive driving sends fuel consumption soaring, and it’s no exaggeration to hit 12 liters per 100 km with a heavy foot. Driving more gently in daily use helps. With performance cars, you can’t have your cake and eat it too—if you want fast acceleration, you’ll need to feed it more fuel. I recommend using high-quality engine oil and regularly cleaning carbon deposits to optimize fuel efficiency, but at the end of the day, if you bought it for the thrill, don’t sweat the numbers too much.

I'm quite sensitive about car fuel consumption, especially for high-performance models like the A45. Its official combined fuel consumption is rated at 8.5 to 10 liters per 100 kilometers, but in actual city driving it can exceed 10 liters, while on highways it's around 7.5 liters - this has a significant carbon emission impact, being notably higher than comparable vehicles in its class. Driving habits are crucial: a single hard acceleration with aggressive throttle input can consume over 1 liter extra fuel, so I recommend gentle driving and avoiding congested routes to reduce emissions. Although the AMG engine is powerful, from an environmental perspective, opting for a hybrid version would be more eco-friendly. In the long run, higher fuel consumption also means annual fuel costs could increase by several thousand, requiring careful consideration of performance needs.

My experience with the A45's fuel consumption shows an average of 9 liters per 100 km, but it can be managed with skill. After driving it for several years, I developed the habit of gently pressing the brake when starting: it drops to 8 liters in the city and stabilizes at 7.5 liters on the highway. Maintaining proper tire pressure and carrying less heavy luggage also helps. Real-world data often exceeds the manufacturer's claimed values, and it's not uncommon for consumption to rise to 11 liters in traffic jams. This is related to AMG's high-performance design: the large turbo needs ample fuel to perform well. I recommend owners regularly maintain and check the oil system to avoid aging components affecting fuel efficiency. Overall, don't expect ultra-low fuel consumption; optimizing driving habits while enjoying the power is the most practical approach.

From my driving experience, the A45's fuel consumption is dynamically variable. When new, it averaged 8.5 liters per 100 km, but after several years of city driving, it has increased to 10 liters. On long highway trips, it averages 7.5 liters. Many factors influence this: using air conditioning in summer adds 1 liter to consumption, engine efficiency is poorer in winter, and slippery roads during rain increase fuel usage. Its powerful performance comes at the cost of faster fuel gauge drops—it's fuel-efficient during gentle cruising, but fuel consumption spikes when switching to S mode. Maintenance tips include regular throttle body cleaning and using premium fuel, which helps maintain stable fuel consumption. When buying such a performance car, be mentally prepared—fuel efficiency isn't its strong suit; reliability and handling are the highlights.
