2016 Mercedes-Benz SL-Class Summary

Peter Anderson road tests and reviews the 2016 Mercedes-AMG SL63 with specs, fuel consumption and verdict.

Well. They don't make cars like this anymore, do they? Time was, a big coupe or convertible were de rigeur for the well-heeled banker, with 12 cylinders almost a given and fuel consumption measured in super tankers, or more likely just not talked about at all.

The world has changed but Mercedes’ SL hasn't. That's not strictly true, of course. The SL63 may drop four of the SL65's 12 cylinders, but at just half a litre smaller and still with twin-turbos it generates the enormous thrust a luxo-barge like this needs. The things that made it an icon are indeed still there - lots of tech, a style all its own and a name everyone recognises.

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.
