2018 BMW 6 Series Summary

What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.

That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.

Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.

I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.

2025 Audi A3 Summary

Can a hatchback still be a fun and fashionable way to get around when the SUV has become such a status trend?

The facelifted Audi A3 certainly makes a case for it.

The refreshed 2025 A3 is, as Audi puts it, more competitive than before when it comes to not only value but also, you might agree, style.

Last year, before the update even arrived, the A3 sold almost as well as its Volkswagen Golf corporate sibling. In fact, it’s Audi’s third most popular model behind the Q3 and Q5 SUVs.

It’s also third in its segment of ‘Small cars under $40,000’, behind only the MG4 electric car and, you guessed it, the VW Golf.

As such, it also outsells its actual closest rivals the BMW 1 Series and Mercedes-Benz A-Class, both of which are close to the A3 on price.

Now that it’s been given a bit more razzle dazzle, let’s see if the A3 can keep that momentum going.

Deep dive comparison

2018 BMW 6 Series 2025 Audi A3

Verdict

This isn't a car for everyone's tastes, but if you fit in to the buyer group that just doesn't really know what they want in a luxury car, it could be the perfect fit for your family. The 6 Series GT is a practical large prestige car, albeit one that will likely find very few buyers.

Verdict

Closing in on $60,000 for a small car isn’t cheap. Ask a car dealer and they might even say the hatchback is a good way to get someone into a showroom to eventually look at an SUV.

But I reckon you’d be doing the A3 a disservice to count it out. It’s always been one of those cars that does everything well, and with this current facelift manages to keep its practicality without becoming boring.

It looks good on the outside, it’s smart on the inside and it’s fun to drive while remaining sensible. Even if you get it in bright yellow.
