How quaint, a diesel engine. It’s a 2.0-litre four-cylinder with 197bhp, and with the car’s 70-litre tank it will propel the car for over 700 miles without needing to visit the pumps.

The car in question is the new Mercedes-Benz GLC220d Coupe, the second generation of the fast-back version of the GLC SUV. The new car is 31mm longer and 5mm higher than the old model with a longer wheelbase and tracks that are 6mm wider at the front and 23mm at the back.

Good for a little bit of extra space inside, not so good for parking and trying to get out of when you’re in a multi-storey car park next to a pillar.

You’d be hard-pressed to spot the difference between the new and old GLC. Just bumpers and lights. Inside there’s the usual high-class entertainment system as used in multiple Mercedes models.

That means a 12.3in digital instrument display and a 11.9in portrait infotainment touchscreen. There are very few buttons so your options for controlling everything are touch-sensitive buttons on the steering wheel, arranged on the four spokes.

They’re rather fiddly to use but you can use the “Hey Mercedes” voice assistant if you have the patience to put up with it completely misunderstanding your commands.

The infotainment system remains a classy operation

While we’re having a bit of moan and in Luddite mode, our test car is fitted with Merc’s augmented reality system which pops an image up of, say, an upcoming junction and puts an arrow on the image that tells you which way to turn.

Trouble is, it obstructs the map view and is more of a hindrance. Fortunately our car also has a head-up display which allows you to see where you’re going without looking at the infotainment screen.

At least everything is beautifully put together and the materials are high quality. As they should be in a car that costs £69,355 in this AMG Line Premium Plus trim.

We’ve got used to car prices having shot up over the last few years, but even so, almost 70 grand for a car with a four-cylinder diesel engine in it is pretty strong. You’ll have no difficulty in getting comfortable up front and there’s plenty of headroom. There is in the back, too, but not quite as much as you get in the SUV version of the GLC. It’s the same with all these coupe/SUVs, including rivals from BMW and Porsche.

The boot holds 545 litres with the seats in place, 45 litres more than in the previous generation. You can thank the extra length for that. There’s an even bigger bonus with the seats folded as the 1,490 litres available is 90 litres more than before.

"We have a well-made comfortable and able SUV coupe that isn’t good value"

There’s another diesel engine available in the GLC (badged as the 300) that is also a 2.0 litre but has 265bhp. Your other option is a petrol engine of the same displacement with 255bhp.

The less powerful diesel is perfectly adequate with enough grunt and is quiet and smooth. Why pay more? The GLC’s ride is comfortable and the handling secure. All versions come as four-wheel drive.

To sum up, we have a well-made comfortable and able SUV coupe that isn’t good value.
