Is the Lexus Nx300 good on gas?
In brief, the NX300 badge isn’t used on the current Lexus NX lineup, and fuel efficiency depends on which trim you choose. The gas-powered options are the NX250 and NX350, with a plug-in hybrid variant (NX450h+) available in many markets. Generally, the NX250 is more fuel-efficient than the NX350, and the NX450h+ can offer the best economy when charged and used for short trips.
The NX300 badge and the current lineup
The NX300 name was used on older Lexus crossovers (such as the NX200t and NX300h in previous generations). In the latest generation, Lexus shifted to naming that centers on the NX250 and NX350 for gas-powered trims, plus a plug-in hybrid option (NX450h+ in many regions). Availability can vary by market and model year, so check local specs before shopping.
Current NX gas-powered trims and fuel economy
Below is a concise guide to the typical fuel economy you can expect from each gas-only NX variant. Real-world results depend on drivetrain (FWD vs AWD) and other factors.
- NX250 (2.5L four-cylinder) — generally the most fuel-efficient NX option; usually offers better efficiency, with FWD typically edging ahead of AWD in combined mpg estimates.
- NX350 (2.4L turbo) — more power and a corresponding drop in fuel efficiency compared with the NX250; combined mpg tends to be in the mid-20s to high-20s range depending on drivetrain.
In short, the NX250 is the more economical choice among the gas-only NX models, while the NX350 prioritizes performance at a modest hit to mpg. Exact EPA numbers vary by model year and drivetrain, so consult the latest ratings for your specific configuration.
Plug-in hybrid option: NX450h+
For buyers prioritizing fuel economy, the NX450h+ adds plug-in hybrid capability, delivering substantial efficiency gains when the battery is charged and used for short trips. It offers electric-only driving for a portion of daily commuting and higher MPGe ratings overall, though availability and pricing vary by market.
Real-world fuel economy and influencing factors
While EPA numbers provide a baseline, real-world mpg can differ due to several factors. The following considerations commonly affect NX fuel economy in everyday use.
- Driving style: smooth acceleration, conservative braking, and steady speeds improve efficiency.
- Terrain and climate: hilly routes, stop-and-go traffic, extreme temperatures, and air conditioning use can raise consumption.
- Drivetrain and tires: AWD typically reduces mpg versus FWD, and tire type/pressure affects rolling resistance.
- Vehicle maintenance: timely maintenance, clean air filters, and proper oil/lubricant choices help sustain mpg.
- Load and aerodynamics: excess weight and roof racks or external accessories can lower fuel economy.
In practice, real-world mpg often trails EPA estimates, especially in city driving with AWD. Your actual mileage will reflect how you drive, where you drive, and how well the vehicle is maintained.
Tips to maximize fuel economy
The following steps can help you get the most from any NX variant. Use these practical tips to approach the EPA estimates more closely in everyday driving.
- Choose eco or normal driving modes to optimize throttle response and climate control for efficiency.
- Accelerate gradually and anticipate traffic to minimize sharp starts and stops.
- Keep tires inflated to the recommended pressure and maintain proper alignment.
- Follow a regular maintenance schedule: timely oil changes, air-filter replacements, and tune-ups.
- Reduce unnecessary weight and avoid roof racks when not needed to lower drag and load.
- Plan routes to minimize idling and use highway cruising where appropriate; use cruise control on highways if suitable.
- If you own the NX450h+, charge the battery regularly to maximize electric driving and MPGe.
- Use climate control efficiently: precondition the cabin while plugged in and limit continuous cabin heating or cooling when possible.
By applying these practices, you can often improve both city and highway fuel economy and come closer to the published figures in real-world use.
Summary
The Lexus NX300 badge is not part of the current NX lineup. For gas-powered efficiency, the NX250 generally offers better fuel economy than the turbocharged NX350, while the NX450h+ plug-in hybrid provides the strongest economy when charged and used for shorter trips. Real-world mpg depends on driving habits, terrain, climate, and maintenance, so review EPA ratings for your exact configuration and model year, and apply practical efficiency tips to maximize fuel economy.
