How many cylinders does the Teana engine have?

The Teana is equipped with a four-cylinder engine. Below is an introduction to engine-related information: 1. Energy conversion: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. 2. Device: The term engine can refer to both the power generation device and the entire machine that includes the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of an engine originates from English, with its original meaning referring to 'a mechanical device that generates power.'
The Altima's engine is quite reliable, with all current models featuring four-cylinder engines. The entry-level version comes with a 2.0L naturally aspirated engine, offering smooth performance and fuel efficiency for family use, with a maximum power output of 156 horsepower, making it perfect for daily commuting. The higher-end 2.0T version is even more interesting, equipped with Nissan's cutting-edge VC-TURBO variable compression ratio technology. It's like an engine that can automatically adjust its heart size—fuel-efficient in the city (compression ratio 14:1) and powerful on the highway (8:1), delivering 239 horsepower with instant acceleration. Although the hybrid version is called e-POWER, its internal combustion engine is still a 1.5T four-cylinder, dedicated solely to generating electricity without driving the wheels, resulting in an impressively low fuel consumption of just over 4 liters. The older models once featured a V6, but that's no longer available—now, the entire lineup is solidly four-cylinder.
Last year, I test drove the Teana, and the salesperson clearly stated that all current models are equipped with four-cylinder engines. The base model features a 2.0L naturally aspirated engine with the code name MR20, known for its durability and low maintenance costs. The high-end model comes with a 2.0T variable compression ratio engine, the KR20, which can accelerate from 0 to 100 km/h in under 7 seconds in real-world tests. The most unique is the e-POWER version, which uses a 1.5T three-cylinder engine solely for generating electricity, not for driving, making the driving experience feel more like an electric car since the output is entirely handled by the electric motor. Compared to the Accord hybrid next door, which uses a 2.0L four-cylinder engine, the Teana's system produces less vibration—so much so that kids sleeping in the back seat weren't even disturbed.
Having run an auto repair shop for ten years, I've seen countless Altimas, from the first-gen VQ35 V6 in 2002 to today's four-cylinders. The current lineup mainly features three engines: the MR20 naturally aspirated four-cylinder is low-maintenance; the KR20 turbocharged four-cylinder, though more complex, delivers strong power; and the highlight is the e-POWER's 1.5T three-cylinder—though a three-cylinder, it operates uniquely, fixed at 2000 RPM to generate electricity without direct drive, making vibrations much less noticeable than traditional three-cylinders. All models use 0W-20 oil, and the oil filter is within easy reach.
