Jetta does not have a 1.8L displacement model. Classification of vehicle displacements: In China, passenger car classifications are determined by engine displacement. cars have displacements ≤ 1.0L; compact cars range from 1.0-1.6L; midsize cars range from 1.6-2.5L; executive cars range from 2.5-4.0L; luxury cars have displacements > 4.0L. Total cylinder displacement: Displacement refers to exhaust volume. Cylinder working volume is the swept volume when the piston moves from top dead center to bottom dead center, also called single-cylinder displacement, determined by bore and stroke. Engine displacement is the sum of all cylinder working volumes, usually expressed in liters (L). Engine displacement is one of the most important structural parameters, representing engine size more accurately than bore or cylinder count. Many engine specifications are closely related to displacement.

I've been driving a Jetta for almost ten years, and the displacement changes of this car are quite interesting. The old Jetta King from the 1990s did use a 1.8L naturally aspirated engine, and the acceleration was noticeably strong when you stepped on the gas—many veteran drivers still miss that model. Later, in the early 2000s, the facelifted version mainly switched to a 1.6L engine. However, around 2008, the Jetta Champion Edition briefly reintroduced the 1.8L version, and those models equipped with ESP can still be found in the market today. Nowadays, Jetta has long become an independent brand. For example, the VS5 uses a 1.4T turbocharged engine with a 1.4L displacement, but its power is even stronger than the old 1.8L. The VS7 lineup is entirely powered by the 1.4T engine. If you're specifically looking for a 1.8L displacement, you’ll have to hunt for models over fifteen years old.

Friends who want to buy a Jetta, listen to me, new cars haven't had a 1.8L displacement for a long time. I remember driving the Jetta King at work back in 2000, with a 1.8L engine paired with a 5-speed manual transmission—it didn't struggle even when climbing hills with the AC on in summer. After the 2004 model year, they mostly switched to 1.6L engines, until the limited-edition Jetta Champion in 2007 brought back the 1.8L, which you can still occasionally spot on the road today. The current Jetta lineup has all gone small-displacement turbo, with the 1.5L naturally aspirated and 1.4T being the main options. As for the advantages of the 1.8L, aside from smoother power delivery, its fuel consumption is much higher than today's new cars—my old Jetta used at least 9 liters per 100 kilometers.

Those who know cars are aware that Jetta's displacement history can be divided into three stages. In the mid-to-late 1990s when the second-generation Jetta (codenamed A2) was introduced to China, it initially used a carbureted 1.8L engine. After switching to electronic fuel injection in 1997, it became the classic Jetta King. In 2004, with the facelift to the PQ32 platform, the displacement was entirely reduced to 1.6L. The third stage was the Jetta Champion Edition launched in the 2008 Olympic year, which revived the 1.8L displacement with the EA113 engine paired with a 6AT transmission, lasting until its discontinuation in 2012. The currently available Jetta VA3 uses a 1.5L engine, while the VS5/VS7 models are equipped with a 1.4T. For specific parameters, the old 1.8L had a maximum power output of 92 horsepower, whereas the current 1.4T delivers 150 horsepower.

Young people around me who just got their driver's licenses often ask me if the old Jetta has a large displacement. Actually, the 2007 Champion Edition was the last model with a 1.8L engine, and now you can buy one in the market for just three to five thousand, but it's rare to find one in good condition. I suggest beginners avoid old cars as parts are hard to find and they consume more fuel. The current Jetta VS5's 1.4T is much more powerful than the old 1.8L, making city overtaking effortless. If you really want to experience an old car, pay attention to checking for engine oil leaks, a common issue with Volkswagen's EA113 engine from that era. Also, test the transmission thoroughly, as the old 4AT has noticeable gear shift jerks. Actually, the key to choosing a car depends on your needs: a 1.5L naturally aspirated engine is sufficient for daily commuting, while a 1.4T is better for frequent highway driving.

Last week, I accompanied a friend to the market and happened to see a 2009 Jetta 1.8L Champion Edition. The owner said that with proper maintenance, the car's fuel consumption is around 8L in the city and can drop to 6.5L on the highway, but in reality, it consumes more fuel than the data suggests. The mechanical hydraulic power steering is heavy, making it quite strenuous for women to drive. The biggest issue is that it struggles to pass the annual emissions test, as the National III emission standard now faces restrictions in many cities. If you're considering buying such an old car, you should budget for necessary repairs, such as replacing wear-prone parts like the timing belt and engine mounts. In comparison, the new Jetta models all meet the National VI standard, with the 1.4T version consuming just over 6L per 100 kilometers, resulting in significantly lower operating costs.
