The difference is significant. The 1.5T and 2.0T engines differ greatly in terms of displacement, starting, acceleration, and overtaking. Mazda's 2.0T engine outperforms the 1.5T engine in power, starting, overtaking, acceleration, and displacement. Specific differences: Displacement: The larger the engine displacement, the higher the fuel consumption. The 1.5T engine consumes less fuel than the 2.0T engine. The 2.0T engine also has a higher displacement than the 1.5T engine. Different engines also vary significantly in power. Cars equipped with a 1.5T engine have weaker power when starting but offer higher fuel economy and lower fuel consumption. In contrast, cars with a 2.0T engine have stronger power, leaning towards a sportier performance, but with higher fuel consumption. Maintenance costs: The maintenance costs for a 1.5L engine are also lower than those for a 2.0L engine in the long run.

I've previously driven Mazda models with 1.5L and 2.0L engines, and the main difference lies in their power performance. The 1.5L engine is perfectly adequate for city commuting, offering smooth starts and lower fuel consumption, saving about 1 liter per 100 kilometers compared to the 2.0L. However, it feels somewhat underpowered when overtaking on highways or climbing hills, with noticeably louder noise at higher RPMs. The 2.0L engine, on the other hand, delivers significantly more punch during acceleration, providing immediate response on highways, especially with the exhilarating zoom sound past 4000 RPM. Both transmissions are quite smart in terms of matching, but the 2.0L's power reserve is more suited for those who enjoy spirited driving. Maintenance costs are fairly similar, though higher-end models mostly come with the 2.0L, so it's important to note the price difference when buying used.

Having driven my friend's Mazda 3 with both 1.5L and 2.0L engines, the difference is quite noticeable. The 1.5L engine feels light and agile, making it effortless to follow traffic in congestion with its responsive throttle. The 2.0L version delivers significantly stronger acceleration, especially when climbing hills with full load and air conditioning on, without any struggle. In terms of fuel consumption, the 1.5L is indeed more economical, but the 2.0L also performs quite efficiently during highway cruising. The key difference lies in the driving experience—the 2.0L engine's Skyactiv technology is particularly lively in the high rev range, providing smoother power delivery when exiting corners, with more refined vibrations transmitted through the steering wheel. If you frequently drive on mountain roads, the 2.0L is recommended, while the 1.5L is perfectly sufficient for pure city commuting.

As a car owner, here are my thoughts. The 1.5L engine is quiet enough, with minimal vibration when running the AC at low speeds, making it suitable for beginners or female drivers. The 2.0L offers more robust power, accelerating about 2 seconds faster at full throttle and providing much steadier overtaking on highways. However, in city driving, the 1.5L's 8.5L fuel consumption is more economical compared to the 2.0L's 9.8L, and it also has fewer carbon deposit issues. Both require maintenance every 10,000 kilometers, with similar spare parts costs. If you mainly use it for commuting, the 1.5L version offers better value for money. For frequent long-distance travel or those seeking driving pleasure, the 2.0L has greater potential for later modifications—just changing the exhaust can give it a sporty feel.
