Big change for popular luxury car: 2025 Audi A4 changes its name to A5 as it gears up to take on the BMW 3 Series and Mercedes-Benz C-Class

Audi has revealed its new A4 sedan and wagon, but not as you know it.

The German brand has changed the name of the A4 to A5. The next A4 will be an electric car, as will all future even numbered Audi vehicles and odd numbers are reserved for those with petrol or hybrid power.

So the new A4 is now the new A5.

It is available in sedan and wagon form and is built on the brand’s new Premium Platform Combustion architecture.

Both body styles are longer and wider than before and feature updated styling.

It has a low slung body with larger wheels and wheelbase - the distance between the front and rear wheels - that give it more luxury appeal.

Dynamic LED lighting front and back is paired with a reworked front grille and rear end.

All versions will feature mild hybrid technology and there will be performance focused S variants.

The standard A5 will be available with the choice of petrol or diesel power.

A 2.0-litre four-cylinder turbocharged petrol engine is available in two tunes that pump out either 110kW and 150kW. 

Both are paired with a dual-clutch auto (with as-yet unknown number of ratios) and all-wheel drive is optional on the more potent variant.

A 2.0-litre turbo diesel motor makes 150kW and 400Nm, again matched to a dual-clutch auto and the option of either front or all-wheel drive.

The S5 uses a 3.0-litre V6 turbo-petrol engine to make 270kW sent to all four wheels via a dual-clutch auto.

There are a range of tech updates such as a giant 14.5-inch multimedia touchscreen and an 11.9-inch digital cockpit. There is also an optional 10.9-inch display for the front seat passenger.

Audi is expected to add a plug-in hybrid version at a later date. That model pairs an efficient petrol engine with a sizeable battery and an electric motor to deliver a driving range of up to 100km.
