What is the difference between Mazda PE and P5 engines?
4 Answers
Mazda PE and P5 engine differences: 1. Displacement varies: PE refers to a 2.0L naturally aspirated engine; P5 refers to a 1.5L naturally aspirated engine. 2. Power output differs: The PE 2.0L naturally aspirated engine delivers a maximum power of 116kW and maximum torque of 202Nm; The P5 1.5L naturally aspirated engine produces a maximum power of 86kW and maximum torque of 148Nm. 3. Transmission matching varies: The PE 2.0L naturally aspirated engine pairs with a 6AT transmission; The P5 1.5L naturally aspirated engine can be matched with either a 6-speed manual transmission or 6AT transmission. Both engines feature direct fuel injection technology and utilize aluminum alloy cylinder heads and blocks.
The differences between Mazda's PE and P5 engines are quite distinct. The PE is a 1.5L small-displacement engine from the late 1990s, used in older models like the 323, with just over 90 horsepower. It's quite fuel-efficient but accelerates sluggishly—you have to floor the throttle when overtaking, listening to the engine whine. The P5 is different; it belongs to the SkyActiv series as a 2.0L version, found in recent Mazda3 models, delivering around 160 horsepower. The power delivery is much more direct, with smooth starts and effortless acceleration at city traffic lights. It also incorporates some SkyActiv technology for better fuel efficiency. Having driven a friend's P5-equipped car, I found the handling more responsive. In terms of maintenance, the PE is simpler but parts are harder to find, while the P5 relies more on electronic controls and requires professional servicing. Overall, the PE is an economical, practical choice, while the P5 leans toward performance and modernity. If buying used, I recommend checking the engine's age—older PEs are cheaper but may suffer from rust or oil leaks, whereas the P5 is pricier but worth it.
I've been working with cars for many years. The PE engine is a classic from Mazda, the 1.5L variant. It has a simple structure, small displacement, and low horsepower, feeling a bit sluggish when driving, especially noticeably weak when climbing hills. The P5 engine is a later 2.0L model, with significantly increased power output, quick starts, sharp response, and effortless overtaking. It also incorporates more advanced control systems, such as variable valve timing, optimizing fuel efficiency. In terms of usage scenarios, the PE is mostly paired with compact cars like the Mazda2, suitable for city commuting; the P5 is used in SUVs like the CX-5, handling long trips with ease. Maintenance-wise, the older PE has parts that are prone to failure but repairs are cheap, while the P5 has more electronic components, occasionally causing troublesome diagnostics—I've heard several owners complain about this. The overall difference lies in the generational update: the PE represents low-cost durability, while the P5 is more modern and intelligent. For peace of mind, go with the P5.
From a car enthusiast's perspective, the Mazda PE engine is an old-school 1.5L unit with less than 100 horsepower. It offers linear acceleration but lacks punch, delivering a rather bland driving experience with limited tuning potential. The P5 engine, on the other hand, is a modern 2.0L powerhouse boasting over 150 horsepower and aggressive torque output. Equipped with dual overhead camshafts, it delivers lightning-fast throttle response, making it thrilling on both tracks and mountain roads, while maintaining fuel efficiency advantages. Having test-driven both, the differences are immediately apparent: the PE feels sluggish in older vehicles with delayed acceleration, whereas the P5-equipped Mazda3 feels nimble – even cornering becomes exhilarating. Technologically, the PE lacks advanced electronic assists, while the P5 features optimized intake/exhaust systems for enhanced efficiency. Maintenance-wise, the PE is more reliable but outdated, while the P5 requires regular electronic system checks. Their applications differ significantly – the P5 offers far greater tuning potential for modifiers.
