Sharp on the outside, sumptuous on the inside: can the new NX surpass Audi and co?

Toyota and Lexus have, over the years, worked to make their shared, economy-maximising hybrid-drive powertrains feel more natural, particularly where the matching of vehicle acceleration to engine speed is concerned. The set-up in the Lexus NX represents the latest step in this process and the level of sophistication achieved is commendable, if not always able to match the best efforts of the Otto-cycle crowd.

In the NX 350h, performance itself is acceptable but modest, our test car reaching 60mph in 7.1sec but then needing another 12 seconds to reach triple figures. By comparison, the latest Hyundai Tucson Hybrid – a crossover lower in both price and status – was just 0.5sec slower to 60mph and actually quicker to 100mph.

German rivals tend to deliver a smoother low-speed ride; F Sport hardware might fare better here. Engine soundtrack is sometimes at odds with self-styled luxury billing.

From the saloon ranks, at this price and footprint, you might also find yourself looking at the BMW 3 Series 330e M Sport, which we would expect to reach 60mph in less than six seconds without breaking a sweat. Those wanting more from their mid-size Lexus crossover should therefore opt for the plug-in hybrid NX 450h+ over the NX 350h. The former’s combined 302bhp gives it a turn of pace comparable to that of the BMW.

That said, for the kind of low-stress, everyday driving for which it is intended, the NX 350h does just fine. This hybrid system is roughly 25% more powerful than the one in the old NX, and this manifests in the form of easy all-electric running at town speeds and snappy roll-on acceleration out on the open road. Only when the battery is very low on charge, and the car then needs to rely heavily on engine power for urban driving, does this powertrain begin to feel a touch ill-conceived.

That, and when strong acceleration is called for. Here, Lexus’s hybrid system still reverts to its old problem, whereby the flailing engine feels oddly detached from the driving controls, and the amount of progress made feels less significant than the level of noise made. It never lasts long but is enough to make more interested drivers think twice about owning the NX 350h.

As for the attractive shift paddles mounted to the steering wheel, they are little more than ornamentation, often having no effect at all on how the powertrain is behaving.
