Audi A4 buying guide

A4 models are offered with a selection of different trim and engines. Keep reading to learn more about each option so you can pick the right version for you.

What Audi A4 trim levels are there?

The entry-level trim for A4 models is called Technik, borrowing its name from the brand’s “Vorsprung durch Technik” mantra. This trim includes alloy wheels, LED headlights, front and rear parking sensors with a rearview camera, cruise control, an infotainment system with sat nav, digital dials, Apple CarPlay and Android Auto.

Sport is the next step up and adds larger alloy wheels, a slightly more aggressive body kit, leather sports seats up front and an interior LED lighting package.

S Line is Audi’s even sportier trim and competes with Mercedes’ AMG-Line and BMW’s M Sport. You get even larger alloy wheels, an even meaner-looking body kit, and even sportier front seats to keep you in place around bends. You also get upgraded LED headlights with sweeping indicators and sports suspension, which is lowered by 23mm compared to regular models.

At the top of the range sits Black Edition. This is similar to S Line versions but leans into the black theme, with black badges, black exterior styling details and black inlays in the cabin. You also get some of the flashiest alloy wheels Audi has in its catalogue.

Audi A4 interior and technology

Audi has long been known for building excellent cabins and the A4's doesn’t disappoint. All functions are laid out in a simple, ergonomic fashion making everything easy to use, but it doesn’t skimp on style, with an elegant layout and upmarket materials. All post-facelift versions gain Audi’s Virtual Cockpit, which adds a screen in place of the driver’s dials, helping the A4 feel suitably high-tech.

Audi’s infotainment system is one of the best in the industry, with all the functions you’d expect and an intuitive, responsive interface. All post-facelift versions get Apple CarPlay and Android Auto as standard so you can easily and safely interact with your smartphone on the move.

While it’s no van, the A4 makes a great practical choice for family buyers. The interior is large enough for five adults, and there’s enough room in the back seats to manoeuvre awkwardly shaped child seats into position. Boot space is strong on both the saloon and Avant estate models but the latter is a better choice for carrying dogs or bulky cargo.

Audi A4 engine range explained

Audi A4 35 TFSI

The entry-level petrol choice for the A4 is the 35 TFSI. This is a 2.0-litre turbo four-cylinder with 150hp, which can complete the 0-62mph sprint in under nine seconds. Average economy can rise as high as 47mpg if you drive gently.

Audi A4 40 TFSI

If you’re looking for a little more punch from your A4’s engine, check out the 40 TFSI option. This turns up the boost on the 2.0-litre engine to 190hp, dropping the 0-62mph time to less than eight seconds.

Audi A4 40 TFSI 204

Audi bumped up the power output of the 40 TFSI engine with the A4’s facelift. As a result A4 40 TFSI models built from 2020 onwards now come with 204hp, which drops the 0-62mph time to a whisker over seven seconds.

Audi A4 30 TDI

A4s have long been a favoured weapon of choice for high-mileage drivers, with the 2.0-litre diesel engine choices remaining a popular choice for several generations. The entry-level 30 TDI makes 136hp, which can still accelerate this model to 62mph from rest in less than 10 seconds. Average economy can crest 70mpg if you drive with a light foot.

Audi A4 35 TDI

Most diesel A4s come equipped with the 35 TDI engine option. This boosts power to 163hp, dropping the 0-62mph time down to less than nine seconds. Average economy stands at 66mpg if you can resist using the extra power.

Audi A4 40 TDI

For buyers that want the long-legged range of a diesel but crave a little power under their right foot, the 40 TDI option might be just right. Here, the 2.0-litre diesel makes a strong 204hp, which is enough to get the 40 TDI to 62mph from rest in around seven seconds.

Audi A4 S4 TDI

The king of the hill among A4s is the S4 TDI. This wades into battle with a mighty 3.0-litre turbodiesel six-cylinder engine making nearly 350hp. Combined with the standard automatic gearbox and quattro all-wheel drive, the S4 TDI sprints from 0-62mph in just 4.8 seconds – just a stone’s throw from the kind of performance you’d expect from an out-and-out supercar.
