2021 Lexus IS Summary

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.

2023 Mazda 6 Summary

Has it really been 20 years since the humble Mazda6 station wagon hit our roads? You betcha, but I was more shocked that I remembered when it did!

I have a sudden flashback of questionable fashion choices, glittery butterfly hair clips and how Skipper was making a play at being the coolest 'Barbie' (she wasn't).

I've always had a soft spot for wagons, they are the forgotten heroes for family hauling. It's hard not to glide over them when the market is dominated by SUVs but if you happen to remember they still exist (albeit, barely) you might remember why they were popular back in the day.

Being a 20th Anniversary Edition means there are some nods to the past in this model but unlike the low-slung jeans of my youth, they're stylishly done. With some luxuriously-appointed rivals to contend with, like the Skoda Octavia and Volkswagen Passat, does it offer enough to be considered by a modern family?

My little family of three has been in it all week to find out for you!

Verdict

Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.

While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.

Verdict

So, what did my family think about the Mazda6 20th Anniversary wagon? Firstly, I like that it drives well and how many luxe features are up front. The trims and body paint look divine but there's a disconnect with family practicality in the back seat. Besides the multimedia system, which 100 per cent needs to be improved, I don't mind the retro-feeling elements in the cockpit but my husband's first comment was that it looked old.

It may be better suited to a smaller and older family that isn't carting around a stack of gear but you get a lot of features for your cash in this model. So, this gets a 7.0/10 from me.

My son didn't spend heaps of time in this one but he liked the colour of it and the seats. He gives it a 7.0/10.
