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.

2026 Tesla Model 3 Summary

It’s been in Australia since 2019 and despite the arrival of a comprehensively upgraded version in late 2023, the Tesla Model 3’s once gargantuan popularity has been declining in recent years.

A seemingly never-ending influx of pure-electric alternatives, primarily from China, has eroded the mid-size sedan’s positioning as the go-to, best-value EV choice. 

But to its credit Tesla has again evolved the Model 3 proposition with the introduction of this Long Range Rear-Wheel Drive grade in October last year, at the time positioning it as “the longest-range EV in Australia”.

Since then, Tesla has adjusted the model grade name to Premium Long Range Rear-Wheel Drive.

Some additional tweaks, made in response to customer feedback, also illustrates the EV pioneer’s determination to step up in the face of increasingly fierce competition.

So, does this latest Model 3 do enough to earn a spot on your electric vehicle shopping list? We spent a week behind the wheel to find out.
