What kind of engine does the Atenza have?
3 Answers
The Atenza is equipped with a Skyactiv-G engine. The main components of the engine include: 1. Valve train; 2. Crankshaft and connecting rod mechanism; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Fuel supply system. Taking the 2020 Atenza as an example, it belongs to the mid-size sedan category, with body dimensions of: length 4870mm, width 1840mm, height 1445mm, and a wheelbase of 2830mm. The 2020 Atenza is powered by a 2.0L naturally aspirated engine, delivering a maximum horsepower of 158ps, maximum power of 116kW, maximum torque of 202Nm, and is paired with a 6-speed automatic transmission.
I've been researching Mazda models for a long time, and the Atz's engine is truly distinctive. It comes equipped with Mazda's self-developed SKYACTIV series engines across the entire lineup. In the early stages, it mainly featured naturally aspirated 2.0L and 2.5L displacements, like the SKYACTIV-G. The most impressive aspect is its ultra-high compression ratio, with the standard version achieving 13:1, and it can run on 92-octane fuel in China. Starting with the 2019 model, Mazda introduced spark-controlled compression ignition technology, called SKYACTIV-X, with the compression ratio soaring to 18.8:1, delivering surprising fuel efficiency and power response. This engine excels in fuel economy and quick throttle response, and when paired with Mazda's tuned 6AT transmission, it feels particularly smooth and responsive to drive. However, the compression ignition version is relatively rare in China, with most vehicles on the road being the 2.5L naturally aspirated version.
I've been driving the Atenza for two years, and its powertrain is quite reliable. It uses Mazda's signature Skyactiv engine, and most models on the road now are equipped with the 2.5L naturally aspirated version, delivering a maximum of 192 horsepower. The key advantage is its excellent fuel efficiency – I've achieved as low as 6.3L/100km on highways, and it's only around 8L/100km in city traffic with frequent congestion. The transmission is exceptionally well-matched, downshifting very promptly when you floor the accelerator. The newer models after 2019 even feature the cutting-edge Spark Controlled Compression Ignition (SPCCI) technology, offering stronger power and lower fuel consumption, though at a higher price. If you're considering a used one, pay attention to the engine model number on the identification plate for clarity.
