What cylinder is the Lexus NX hybrid?
The Lexus NX hybrid uses a four-cylinder engine.
Beyond the basic question, the NX lineup pairs a 2.5-liter four-cylinder petrol engine with electric motors in its hybrid configurations. In most markets, the core options are the self-charging NX 350h and the plug-in NX 450h+, both built around the same four-cylinder base and electrified drivetrain. There is no V6 option in the NX hybrid family.
Engine configuration and cylinder count
All NX hybrid models rely on a 2.5-liter inline-four gasoline engine paired with electric motors. The engine operates in Atkinson-cycle mode to maximize efficiency, and the hybrid system uses an electric continuously variable transmission (e-CVT) to blend power from the engine and motors. Across the NX hybrids, the cylinder count remains four, prioritizing efficiency and smooth operation over larger-displacement options.
Two main hybrid configurations
Below is a concise look at the two primary NX hybrid configurations offered in many markets. The list highlights how each variant uses the same four-cylinder core with different battery and electric-motor setups.
- NX 350h: Self-charging hybrid with the 2.5-liter inline-4 engine paired with electric motors; no plug-in charging capability.
- NX 450h+: Plug-in hybrid variant with a larger battery and electric motors; can operate on electric power for short distances and offers higher total system output in markets where it is available.
Both variants share the four-cylinder engine foundation, with the primary differences being battery capacity, electric range, and overall performance characteristics rather than a different engine cylinder configuration.
What this means for buyers
From a cylinder perspective, the NX hybrid lineup remains four-cylinder across the board. The choice between 350h and 450h+ is driven by battery size and the degree of electrification you want — including whether you need an electric-only driving option — rather than a change in engine architecture.
Summary
The Lexus NX hybrid is powered by a four-cylinder inline-4 engine paired with an electric drivetrain in both its self-charging (350h) and plug-in (450h+) variants. This configuration emphasizes efficiency, quiet operation, and refined daily driving without introducing a V6 option in the NX lineup.
Is the Lexus NX 4 or 6 cylinder?
Engine, Transmission, and Performance
The 2025 NX has two nonhybrid powertrain options. The base NX250 comes with a 203-hp 2.5-liter four-cylinder, while the NX350 is powered by a 275-hp turbocharged 2.4-liter.
Which Lexus SUV has a 6 cylinder?
Lexus offers several 6-cylinder SUVs, most of which are powered by a twin-turbocharged V6 engine. The LX is a large luxury SUV with a twin-turbo V6, and the GX is a rugged, mid-size SUV also featuring a twin-turbo V6. Additionally, the TX 550h+ is a plug-in hybrid SUV with a 6-cylinder engine.

What are the common problems with the NX hybrid?
A 2020 Lexus NX Hybrid is experiencing power loss, increased fuel consumption, black smoke from the exhaust, engine stalling, and a strong exhaust smell. These issues may be linked to a low-pressure fuel system fault, potentially caused by incorrect software values for the fuel pump.
Is the Lexus NX 350 a 4-cylinder?
NX 350h (FWD/AWD): Horsepower and Hybrid Electric
The NX 350h brings power and fuel economy improvements, pairing the D4-S fuel injection 2.5-liter, 4-cylinder gasoline engine with up to two high-torque electric drive motor-generators for strong acceleration and passing performance.
