The Lexus NX 300h is a five-door SUV with extrovert styling. Sitting beneath the bigger RX 450h in the Lexus line-up, the NX 300h shares much with its bigger brother, including what Lexus calls a 'self-charging' hybrid powertrain and standard four-wheel drive.

The NX 300h has many rivals, such as the Audi Q5, BMW X3 and Range Rover Evoque if you’re prepared to look at traditional diesel power, but pickings are a bit thinner in SUV class if you want to be greener. The Hyundai Kona is an attractive electric SUV, but it hardly has the badge kudos of the Lexus, and the same could be said of both the MINI Countryman S E All4 and Mitsubishi Outlander PHEV plug-in hybrids.

The Volvo XC60 Twin Engine is more upmarket though, and life will surely become tougher for the NX 300h when BMW and Audi introduce hybrid versions of the X3 and Q5 respectively.

Unlike most of its SUV rivals, the Lexus doesn’t need to be plugged in to a mains socket to charge its battery. The SUV’s main propulsion unit is a 2.5-litre petrol engine, which is assisted by an electric motor to maximise fuel efficiency. There’s a relatively small battery under the floor at the rear and this is topped up by the engine and regenerative braking – a system that harvests waste energy when the car slows down.

The engine drives through a CVT gearbox, which is a type of automatic designed to keep the engine at optimum efficiency. All NX 300h trim levels feature four-wheel drive.

In use, the electric batteries can provide 100% of the drive and particularly in city stop-start situations, the Lexus will often drive for short periods at low speed in electric-only mode. However, the batteries only store sufficient energy for around a mile of driving, after which the engine cuts in to power the car and recharge the battery.

This means the NX is good around town and in stop-start traffic, but plug-in hybrids have a significant edge with their larger batteries and much greater electric-only range.

There are several ways to order your Lexus NX 300h, starting with the entry-level model. It’s as well equipped as you’d expect a premium SUV to be: the kit list includes 18-inch alloys, the Lexus Safety System+ pack of safety kit, heated front seats with Tahara upholstery and eight-inch sat-nav.

The sat nav can be upgraded to a 10-inch screen as an option (but is poor by class standards regardless of screen size), while a Sport Pack can also be added, bringing a bronze/machined finish to the wheels, as well as a black spindle grille and black door mirror casings.

F Sport cars offer styling upgrades designed to make the NX look a little racier, while the NX 300h Takumi is the range-topper, and it’s lavishly specced with a panoramic roof, heated and ventilated front seats, a 360-degree camera, head-up display, leather upholstery, 14-speaker Mark Levinson stereo, blind-spot monitoring and rear cross-traffic alert.

There’s no doubt the NX 300h is a sporty looker, but on the road it loses out in comparison to rivals, as it’s not very engaging to drive. It handles tidily enough, but the ride is less compliant than a BMW or Range Rover over the UK’s potholed roads and the steering feels a bit remote.

The biggest drawback is the CVT gearbox, which makes the engine rev noisily before the car begins accelerating. It means the response feels sluggish, while the revving engine drones and doesn’t sound at all sporty.

For drivers unconcerned about sporty credentials, the NX 300h offers a luxurious and spacious experience with a proper premium feel. It makes most sense around town, where it’s clean and relatively efficient compared to diesel rivals, although those more traditional SUVs will tend to be more economical over higher mileages.
