Lexus pivots to PHEV tech with NX 450h+

In This Article:

Toyota continues to secure its place as Europe’s number two brand, second only to Volkswagen. But what of Lexus? Globally it was a record 2024, deliveries reaching 851,214 units of which Europe region accounted for 82,571 vehicles (according to Lexus HQ in Japan; Lexus GB says it was 88,184). Within that, the UK comprised 16,678, a 4.5 per cent gain over 2023 and the best result yet.

Worldwide, electrified model variants rose to a new high (52 per cent) though that percentage was even greater in not only the UK but all of the European region. Reinforcing that, the best selling NX range offers both HEV and PHEV versions, a distinction it shares with the larger RX.

In the British market, registrations exceeded 4,300 last year, of which two thirds were the plug-in hybrid. And for the greater European region, the NX sales tally was 26,635 (HEV: 16,841, PHEV: 9,182) making it the number one model. The smaller LBX, a newer hybrid-only SUV, was in second place with 23,018 deliveries. Then came the RX (13,772) followed by the UX (10,959 of which only 1,860 were the EV).

Clearly, buyers like the idea of being able to choose which powertrain best suits their needs and budget, the NX 450h+ sitting at the top of the line-up, the plus signifying a plug-in hybrid. In some other regions there is now a third PHEV, that being the TX 550h+, but this big, US-built SUV is restricted mainly to North America.

Not a turbocharger in sight

Whereas the TX comes with a 3.5-litre V6, the NX is instead powered by a 136 kW (185 PS) and 228 Nm 2.5-litre four-cylinder engine, supported by two motors. Their outputs are 134 kW (182 PS) with 270 Nm (front) and 40 kW (54 PS) plus 121 Nm (rear). Lexus quotes combined power as being 227 kW (309 PS). All of these numbers are for the all-wheel drive 450h+.

In some countries, though not the UK, there is also an NX 400h+ which has the same engine and 18.1 kWh battery but lacks a motor on the back axle. Drive therefore is to the front tyres only. Lexus GB counters this by offering the 350h in FWD or AWD forms. There are also multiple trim levels for both h and h+ powertrains.

Quiet though not always peaceful

The first thing which immediately strikes you about any Lexus is how quiet it is. The test vehicle was typical, even when the engine started itself. Impressive engineering with an emphasis on minimising or eliminating NVH levels at source has long been an obsession for the brand. The EV range is good too, though around 30-40 miles seems a real-world distance rather than the 55 quoted as the official WLTP number.
