How many cylinders is the Lexus NX 300?
The Lexus NX 300 has four cylinders.
Historically, the NX 300 badge referred to a 2.0-liter turbocharged inline-4 engine. In recent U.S. market lineups, Lexus has used other names for NX variants (such as NX 250, NX 350, and NX 350h). Across generations and markets, the NX family predominantly uses four-cylinder engines, including turbocharged, naturally aspirated, hybrid, and plug-in hybrid configurations.
Engine configurations in the NX family
Below is a snapshot of how the NX model names map to cylinder counts in common markets and generations.
- NX 300 (historical): four-cylinder engine (2.0-liter turbocharged inline-4).
- NX 250: four-cylinder engine (2.5-liter naturally aspirated inline-4).
- NX 350: four-cylinder engine (2.4-liter turbocharged inline-4).
- NX 350h: four-cylinder hybrid powertrain (2.5-liter Atkinson-cycle inline-4 with electric motors).
- NX 450h+: four-cylinder plug-in hybrid powertrain (2.5-liter inline-4 with electric motors).
In practice, the cylinder count across the NX lineup remains four cylinders for all current non-performance variants, with the hybrid and plug-in variants sharing the same four-cylinder base paired with electric motors.
Notes by market and generation
Some regions outside the United States continue to use the NX 300 badge for a 2.0-liter turbo engine in older or specific market variants. Since the second-generation NX (launched around 2021), Lexus has largely adopted the NX 250/350/350h naming in many markets, so the NX 300 badge is less common in new-car fleets there. Always check the exact engine specification for a given model year and market when evaluating a vehicle.
Summary
The Lexus NX 300 uses four cylinders, specifically a 2.0-liter turbocharged inline-4 in its traditional configuration. Modern NX variants carry different names (NX 250, NX 350, NX 350h, NX 450h+) but remain four-cylinder-based, with hybrids and plug-in hybrids adding electric motors rather than extra cylinders. Verify the exact engine and power output for a given year and market when researching a specific vehicle.
