What is the fuel consumption of a 1.4T engine?
3 Answers
Most cars equipped with a 1.4T engine have a fuel consumption of around 7.5 liters per 100 kilometers. The 1.4T engine with a maximum power of 150 horsepower, which is currently the most powerful engine installed in the T-Roc, has a relatively higher fuel consumption. Relevant information about fuel consumption is as follows: 1. Introduction: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. 2. Testing method: The test can be conducted on the road or on a chassis dynamometer, and then the fuel consumption per 100 kilometers is calculated using the 'flow meter method' or 'carbon balance method'.
It's actually quite difficult to give a definitive number for the fuel consumption of a 1.4T engine. After driving my car with this displacement for over two years, I've found there are too many factors affecting fuel efficiency. For example, during my daily urban commute with frequent traffic lights and congestion, the dashboard shows fuel consumption fluctuating between 7.5-8.5 liters. But on weekend highway trips, it's a different story - maintaining 100 km/h with cruise control can drop it to around 5.8 liters, with my personal best being 5.3 liters. Vehicle weight is another key factor; my friend's SUV with roof racks consistently consumes about 1 liter more than mine. Driving habits make a huge difference too - my gentle acceleration and minimal braking style contrasts with a colleague who loves aggressive overtaking, resulting in 10% higher fuel consumption in the same model. Overall, 6.5-9 liters per 100km is a normal range for this engine size, with actual consumption largely depending on usage patterns.
The fuel consumption of a 1.4T engine largely depends on the turbo's working state. I've noticed it's quite fuel-efficient before the turbo kicks in. On highways, when the turbo is fully engaged, the performance is impressive, but in city driving with frequent stops and starts, the turbo often operates near its engagement threshold, which can actually increase fuel consumption. From my experience, carrying over 200 kg noticeably raises fuel consumption, and using air conditioning typically adds about 1 liter. Fuel quality also matters—using substandard 92-octane gasoline can cause rough engine operation, increasing consumption by 0.5 liters per 100 km. After the first maintenance, I observed a drop of 0.8 liters in fuel consumption, highlighting the importance of regular servicing. The advantage of this displacement is fuel-efficient mid-range acceleration, though new cars tend to have higher fuel consumption during the break-in period, stabilizing after about 5,000 km.
