Lexus RX450H vs Lexus IS

What's the difference?

This is a review with a difference. For three days, I had a Lexus RX450h and thought it was pretty terrible to drive. Every time I turned the steering wheel, the tyres would squeal as though they weren't inflated with air but instead with tiny, fluffy kittens.

I was bitterly disappointed. How could a car get out the door of the Lexus engineering division with such an aversion to corners. I mean, I know it's not meant to be a corner-carving monster, but normal cornering should have been okay.

After those three days, I'd had enough. The low tyre pressure warning light came on and the penny dropped. I hadn't even thought to check the pressures. They were very, very low. Like only at two-thirds of recommended. So after visiting three separate establishments to find a working pump, I had a whole different car.

One question frequently discussed in the skunkworks of the CarsGuide office is: What exactly does Lexus stand for?

When the brand debuted its original export-market IS sedan in 1999 the messaging was more or less clear: Toyota’s premium sub-brand was here to be a Japanese BMW.

The brand even employed Nobuaki Katayama – chief engineer on the iconic Corolla AE86 program – to again take the reins of its small rear-wheel drive sedan program.

As the years went on though, Lexus changed. Fundamentally geared toward the US market, the second-generation (wild IS F aside) became a bit more sedate and softer around the edges, while the third generation strayed even further from the sedan’s performance-inspired roots, leaning into a plush interior, hybrid drive, and even CVT transmissions.

This brings us to today’s Lexus IS. Essentially a heavy facelift of the third generation (which arrived back in 2013), the brand has “reimagined” its core sedan with a tweaked design and updated technology for 2021.

Is it enough to keep it relevant against its ever-present European rivals and the newly arrived threat from Hyundai’s Genesis G70? I took a signature IS300h hybrid for a week to find out.
