2020 Lexus RX 450h review: dependably different

In 1983, Toyota’s CEO challenged his company to build “a car that is better than the best in the world”. The benchmark Eiji Toyoda had in mind was almost certainly the Mercedes-Benz S-Class. And the Lexus LS 400, revealed six years later, duly went above and beyond. Its near-silent V8 and peerless build quality led to many a sleepless night in Stuttgart.

The herculean effort put into the LS 400 makes you wonder if it ever made money. No less than 1,400 engineers were assigned to the project, driving 450 prototypes more than 2.7 million miles. Almost 1,000 development engines were tested, too. Oh, and 24 types of wood were assessed for the interior. This was perhaps the closest a ‘mass-production’ car has come to being built without compromise.

The LS 400 wasn’t simply about being the best, though. Its real raison d’être was to launch Toyota’s then-new luxury brand. Thirty years on, the success of Lexus owes much to this flying start. However, the subsequent RX also deserves much credit. When it debuted in 1997, the RX 300 was the original luxury crossover: an SUV with no pretensions to going off-road. The RX 400h of 2004 was another milestone, offering a hybrid alternative to diesel for the first time in its class.

Today, 95 percent of Lexus cars sold in the UK have hybrid power, while the RX is well into its fourth iteration. Which brings me, somewhat circuitously, to the new RX 450h. The time when this SUV had a sector to itself is long gone – competitors include the BMW X5 and Mercedes-Benz GLE – so Lexus has given it a mid-life update for the 2020 model-year.

You could be forgiven for not spotting the differences straight away. Pointier headlights – now with ‘Bladescan’ adaptive high-beam tech – frame a subtly redesigned grille, while the bumpers are better blended with the bodywork. Still, the RX remains a striking design: angular, aggressive and unmistakably Japanese. It looks particularly svelte in F Sport trim, with dark chrome, 20-inch alloys and a sportier chassis. More on that shortly.

Inside, the big news is the arrival of Apple CarPlay and Android Auto, which lets you operate your phone, including music and messages, via the touchscreen (I gave up on the skittish touchpad controller). Quality seems good enough to satisfy even a nit-picking LS 400 engineer, but the cluttered dashboard shows its age. Even if I was perversely pleased to discover a new car that still has a CD player.

I grab the keys to seven-seat RX 450hL and glide away in silent EV mode. Around town, Lexus says up to 50 percent of driving is electric and emissions-free, although the snarling 3.5-litre V6 kicks in when you reach the open road. The E-CVT gearbox reacts promptly, without the ‘rubber band’ lethargy once a hallmark of hybrids, and a combined 313hp petrol/electric output makes for effortless overtaking. However, while a ride softer than a freshly-plumped pillow is lovely in a straight line, it all goes a bit awry in the corners.

To be blunt, the standard RX feels like a car built for America. And indeed it is – this is the bestselling luxury SUV there by a huge margin. Most UK buyers, however, opt for the F Sport, and rightly so; stiffer dampers and beefier anti-roll bars really transform how it drives. It’s still less engaging than, say, a BMW X5, but it no longer feels you’re grazing the door handles on a rural road.

With public opinion turning against diesel, the RX feels more relevant than ever. As a ‘self-charging’ hybrid, it isn’t as cheap to tax as newer plug-in rivals – particularly for company drivers – but it majors on the original Lexus strengths of comfort, refinement and reliability. The LS 400’s legacy lives on.
