The 2026 Lexus NX 450h+ brings plug-in hybrid technology to the NX lineup, and it does something the self-charging NX 350h cannot: it allows you to run on electricity alone for a significant stretch of daily driving before the combustion engine plays any role. Its 18.1 kWh battery delivers an estimated 60 km of electric-only range, which covers the daily commute for most Canadians without consuming a drop of fuel. On longer drives, the system transitions automatically to classic hybrid-electric operation.
The NX 450h+ sits at the top of the NX powertrain lineup, producing 304 combined system horsepower from a 2.5 L four-cylinder engine paired with an electronically controlled continuously variable transmission and AWD through Lexus's AWD-e system. For buyers who want the efficiency of a plug-in, the versatility of AWD, and the premium features of the upper NX grades, the 450h+ delivers all three.
The Plug-In Hybrid Powertrain: How It Works
The NX 450h+ uses a 2.5 L four-cylinder DOHC 16-valve engine combined with Lexus Hybrid Drive technology. The battery system uses an 18.1 kWh lithium-ion battery pack positioned under the floor to lower the centre of gravity. In EV mode, the front and rear electric motors power the vehicle without the combustion engine running, giving the NX 450h+ genuine all-electric acceleration for city driving, parking, and slow-speed manoeuvring.
When the battery charge is depleted, the system transitions to self-charging hybrid operation, maintaining efficiency through regenerative braking and engine management. At that point, fuel economy runs at 6.6 L/100 km combined. Across the full range of operation, for a driver who charges regularly and does most trips within 60 km, real-world fuel consumption can be dramatically lower than the hybrid-only rating suggests.
- Battery: 18.1 kWh lithium-ion
- Estimated EV-only range: 60 km
- On-board AC charger: 6.6 kW
- Hybrid fuel economy (battery depleted): 6.6 L/100 km combined
- System output: 304 combined hp
AWD-e System: Electric-Driven Rear Axle
Every NX 450h+ comes with Lexus AWD-e as standard. Unlike a mechanical AWD system that physically connects front and rear axles, the AWD-e system uses a rear electric motor to independently drive the rear wheels on demand. This means there is no mechanical link between the front engine and rear wheels, making the system lighter and more responsive than conventional AWD arrangements.
The rear motor engages when the vehicle detects wheel slip, during acceleration from a stop, or when navigating low-traction surfaces. Torque distribution between front and rear adjusts continuously. In everyday dry-road driving, the system can run in front-wheel-drive mode to minimize energy consumption; in wet or slippery conditions, rear torque is applied almost instantaneously.
For buyers in New Brunswick, where shoulder seasons bring rain, leaf cover, ice, and spring slush in rapid succession, the AWD-e system's ability to react quickly without the driver doing anything is a practical advantage.
Chassis and Suspension Options by Grade
The AWD-e system runs across all four NX 450h+ grades, but suspension calibration varies. The F SPORT 2 and F SPORT 3 grades add Adaptive Variable Suspension (AVS) and front and rear performance rods, which tighten the body control and steering response. These grades also swap to 20-inch F SPORT black alloy wheels and apply F SPORT styling throughout the cabin.
The Ultra Premium and Executive grades use a more comfort-oriented suspension tune appropriate to their luxury positioning. Both still benefit from the AWD-e system's dynamic torque delivery.
Grade Lineup: Four Configurations
NX 450h+ Ultra Premium establishes the PHEV entry point. It includes the 14-inch Lexus Interface touchscreen with all four connected services, a 7-inch multi-information display, 18-inch alloy wheels, heated and ventilated front seats, heated rear seats, leather upholstery, driver's seat memory, single-colour ambient lighting, power moonroof, power back door, Blind Spot Monitor with Rear Cross Traffic Alert, and 2,000 lbs (907 kg) towing capacity.
NX 450h+ Executive builds on Ultra Premium with a panoramic moonroof, 17-speaker Mark Levinson Premium Audio system, advanced touch steering wheel, head-up display, triple beam headlamps, decorative wood trim, power rear door kick sensor, Advanced Park system, Panoramic View Monitor, and a digital rearview mirror.
NX 450h+ F SPORT 2 (new for 2026) applies F SPORT hardware to the Ultra Premium base: 20-inch F SPORT black alloy wheels, F SPORT NuLuxe seats, 3-spoke F SPORT steering wheel, AVS, front and rear performance dampers, 64-colour ambient lighting, wireless charging dock, digital key, Lane Change Assist, and Intuitive Parking Assist. Black trim accents and painted wheel arch mouldings reinforce the exterior look.
NX 450h+ F SPORT 3 builds on F SPORT 2, adding a Panoramic View Monitor, head-up display, triple beam headlamps, power rear door kick sensor, digital rearview mirror, and a panoramic moonroof.

The NX 350h is the better fit for buyers who want a simple, no-plug-required hybrid with slightly better fuel economy once the battery is not a factor. The NX 450h+ suits buyers who charge at home or at work and want to significantly reduce fuel use on daily trips while still having a full hybrid powertrain for longer drives.
