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.

2018 Mercedes-Benz GLA250 Summary

Buuuuuuuur, parp, buuuuuuuuuuuur, parp. Anyone who knows anything about cars immediately recognises the sound of a 45-engined A-class derivative. It's the sound you hear in a tunnel as old mate blasts past with a giant carbon-fibre wing atop his hatchback. It's the sound you hear at 3:00am on a summer morning (if your suburb has no speed bumps, of course).

In short, that sound means big power from a 2.0-litre turbocharged engine, a seven-speed transmission, and a bunch of Germans who clearly had a sense of humour in charge of tuning the exhaust note.

Sure, the GLA compact SUV is probably a slightly unexpected source of all that noise. But then, Merc's Ingolstadt rivals stuffed Audi's stupendous five-cylinder engine into a Q3 to make the hugely improbable RSQ3, so why not do the same with their skirts-lifted A-Class?

To be honest, my expectations for this car were low. So do I owe Mercedes a grovelling apology? Or can I still claim the moral high ground after a week of GLA 45 "ownership"?
