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.

2020 Audi S6 Summary

Most buyers don’t care for sedans these days, but those in the premium market are still spoilt for choice, with new model after new model being launched.

The latest on offer is the new Audi S6, which once again attempts to mix executive style with boy-racer performance.

With its predecessor’s 4.0-litre twin-turbo V8 succeeded by an engine that is 1.1 litres and two cylinders short, does it still serve up enough bang for your back?

Of course, the only way to find out is to put the new S6 sedan to test, so that’s exactly what we did. Read on.
