Why is the fuel consumption of Jetta VS7 so high?
3 Answers
The high fuel consumption of Jetta VS7 is caused by the engine's technical condition leading to excessive fuel consumption. The following is an introduction about Jetta VS7: 1. Overview: Jetta VS7 is another SUV product under the Jetta brand, positioned as a mid-size SUV. With the launch of VS7, Jetta's SUV product line has been further enriched. 2. Exterior: It adopts Jetta brand's latest design language, featuring a newly designed brand logo with distinctive personality. The polygonal chrome dot-matrix front grille combined with layered LED headlights on both sides gives people a brand-new perception of Jetta. The added LED daytime running lights, along with the neat front bumper matched with silver front lip decoration, further create a sporty atmosphere.
I've been driving the Jetta VS7 for almost two years now, and I've figured out a few things about its high fuel consumption. First, it's normal for a 1.4-ton SUV to consume more fuel than a sedan, especially when a 1.4T engine is pulling such a large body. During peak traffic hours in the morning and evening, fuel consumption is at its highest, with the gauge showing up to 11 liters per 100 km, but on the highway, it stabilizes at around 7 liters. I recommend developing good habits: avoid sudden braking and acceleration, and maintaining a steady speed of 60-80 km/h is the most fuel-efficient. Also, remember to check tire pressure, as low pressure increases rolling resistance and significantly boosts fuel consumption. Running the air conditioning in summer also consumes more fuel, so for short trips, I find it more economical to just open the windows for ventilation. Lastly, I suggest installing a real-time fuel consumption monitor—it clearly shows which driving behaviors are the most costly.
After driving the VS7 for half a year, I found its actual fuel consumption differs significantly from the official figures. Here are my key observations. The engine tuning is relatively conservative—150 horsepower pulling a midsize SUV often leads to excessive fuel injection during power delivery. There are also minor transmission matching issues; the automatic gearbox hesitates for about half a second around 2000 RPM, wasting fuel. Driving conditions play a bigger role—commuting during rush hours in cities like Beijing, Shanghai, or Guangzhou pushes fuel consumption above 10L/100km on the display. Another detail is oil viscosity; switching to 5W40 during the first maintenance noticeably improved smoothness and fuel efficiency compared to the factory oil. Regular throttle body carbon cleaning and spark plug replacement are crucial—doing this every 20,000 km reduces consumption by about 0.5L/100km.
