Audi’s finalised plans for the all-new A4 include an electric-only four-wheel-drive performance RS model and a hybrid RS4 to top a line-up underpinned by two different platforms, according to well-placed Ingolstadt insiders. One platform will be used for combustion-engined hybrid variants and the other for pure-electric models.
The sixth-generation Audi A4 is due to go on sale in the UK in 2023. Volume-selling versions of Audi’s long-running BMW 3 Series rival will continue to be sold in saloon and estate (Avant) bodystyles based on a modified version of the existing MLB platform, which underpins a wide variety of other Volkswagen Group models.
The Audi A4 Avant has now broken cover for the first time on public roads, giving clues to a design overhaul that will bring it into line with Audi's newer models, including the E-tron line of EVs. A low, wide front grille, slimline headlights and a more rakish roofline look to be the key differentiators from the current car – and while this mule's distinctive circular rear lights may not make it to production, we would expect a redesign at the back, too.
The new A4 will offer a range of upgraded petrol and diesel engines equipped with either mild- or plug-in hybrid assistance and offered in both front- and four-wheel-drive (quattro) layouts.
Markus Hoffmann, head of R&D at Audi, said: “We already have electrification modules today, from mild hybrids to plug-in hybrids – and we will be focusing even more intensively on electrification in the cars that follow.”
Electrification will extend throughout the range, all the way up to the successor to the RS4, which will retain today’s twin-turbocharged 2.9-litre V6 petrol engine but is in line to receive electric assistance that will lift its output beyond the 444bhp and 443lb ft of the existing model.
Also under development at the German car maker is the new pure-electric A4 E-tron. Set to challenge the Tesla Model 3 and newly unveiled BMW i4, it is based around the Premium Platform Electric (PPE) architecture that has been developed in a joint engineering programme between Audi and Volkswagen Group sibling company Porsche.
The PPE platform used by the A4 E-tron will be shared with the upcoming Audi Q6 E-tron, as well as an electric version of the secondgeneration Macan currently under development at Porsche. The architecture will also underpin the new Audi A6 E-tron, recently revealed in concept form and which, like the A4 E-tron, will be sold alongside its combustion-engined namesake until petrol and diesel are discontinued.
The new electric A4 is set to adopt broadly similar exterior styling to its combustion-engined siblings but will be differentiated visually by a blanked-off grille and other unique design elements to further improve its aerodynamic efficiency. Although not yet confirmed, it is likely to feature a five-door layout with a liftback-style tailgate similar to today’s A5 Sportback, following the lead of the A6 E-tron.
The A4 E-tron will be sold with a choice of single-motor rear-drive and dual-motor four-wheel-drive (quattro) layouts when it arrives in 2024.
The line-up will be crowned by an electric RS performance model from the Audi Sport division, packing up to 469bhp and 590lb ft.
Audi is committed to introducing up to 20 new pure-electric models by 2025. But with the existing A4 accounting for roughly a fifth of annual global Audi sales in recent years, a move to electric power exclusively for its successor was considered too premature by Ingolstadt decision makers, who have said the company will produce petrol and diesel A4s through to 2030.
