Audi A5 Coupe: Taking on the A4 Saloon

  • Our long term A5 Coupe meets the A4 saloon
  • Both cars are fitted with 2-litre Ultra diesel engine
  • One is more practical while the other more pleasing on the eye

If you grew up in a large family like me you’ll know all about the constant bickering, comparisons and mistaken identities that happen between siblings.

No matter how many times you’ve told your great auntie Maureen that you’re not your older sister, she still never manages to remember. And the amount of times she then proceeds to compare the two of you afterwards... well, you catch my drift.

We recently had an A4 saloon in on test and I thought I’d take a leaf out of Maureen’s book and see how the A4 Saloon compares against our long-term Audi A5 Coupe.

On paper

Both cars are fitted with Audi’s 2-litre TDI diesel Ultra engine and offer identical performance figures. The 163bhp and 400Nm enables both cars to accelerate from 0-62mph in 8.3 seconds with a top speed of 140mph.

Running costs are identical for both cars too, which suprised us as our Coupe is lighter than the Saloon. The 2-litre Ultra diesel engine is fairly new to both cars and offers impressive combined fuel economy of 67.3mpg and low CO2 emissions of only 109g/km.

The first obvious difference between these two cars is the saloon has five doors while our Coupe has a less practical three. What's probably not immediately noticeable is that the saloon is longer too while the Coupe is marginally wider.

Although looks are subjective, we definitely prefer the look of our long term A5 Coupe, its curves and sloping roof line making it a real head-turner, while the A4 Saloon's design is more conservative; no doubt to appeal to the thousands of company car drivers which order one every year.


Here is where the saloon really stands out, offering more interior room than the Coupe, especially when it comes to headroom for those in the rear which is seriously lacking in our A5.

When it comes to boot space, both cars offer plenty but it's the saloon that comes out on top with 480 litres available verses the Coupe’s 455 litres. The loading lip in the saloon is lower too making it easier to pack your shopping or suitcases in.

Out on the road both cars are luxurious and smooth while the soft suspension soaks up bumps and potholes effortlessly. Both are excellent motorway cars but the saloon is more comfortable over longer journeys and thanks to its slightly skinnier profile, is easy to drive around the town too. 

Trim details

Our long term A5 comes in SE trim and has a price tag of £30,825, the saloon, despite being in the slightly higher trim of SE Technik costs less at £28,675.

Among the standard kit, both cars feature three-zone air-con, DAB Radio, cruise control, 17-inch alloy wheels, automatic boot opening, Milano leather upholstery, electronic parking brake, 6.5-inch colour centre display, Bluetooth and automatic lights and wipers.

The only major differences between the two is that our A5 comes with front and rear parking sensors, the A4 Saloon has only rear sensors and there are heated front seats in our long term A5 while the A4 you’ll have to add as an option for £300.

Plus the striking red paintwork on the A5 Coupe is included as standard but if you want the boring silver paintwork on the A4 Saloon it’ll cost you £615 extra.

Which would we choose?

If I was making this decision using purely my head then it would have to be the A4 Saloon as it’s more practical and comfortable on long journeys. But if I was letting my heart make the decisions (which I frequently do) it would have to be our A5 Coupe which overshadows the conservative A4 Saloon when it comes to good-looks and stylish appeal.
