Audi Has Built An 85kg, 610bhp Inline-Four
DTM is in for a big change this year. The 4.0-litre, naturally-aspirated V8s have gone, replaced with 2.0-litre inline-four turbos.
But you won’t need to worry about the speed dropping. Quite the opposite: power will actually increase from around 500bhp to 600, while the fuel consumption has reduced to a new mandated maximum of 95kg per hour.
Audi has revealed its own power unit for the new regulations, and it’s a fascinating thing. Despite the addition of the turbocharger and all its related components, Audi’s motorsport bods have come up with something that is half the weight of the old V8.
That means it weighs just 85kg, the minimum weight figure allowed under the ‘Class One’ rules. It’ll be used in eight of Audi’s RS5 silhouette racers, competing against new entrants Aston Martin, and DTM veterans BMW.
All DTM machines this year will have a push to push-to-pass system which briefly raises the power by 30bhp while increasing consumption by 5kg per hour.
Audi Motorsport’s engine development boss Ulrich Baretzky reckons there’s potential for road car relevance here, too. He said:
“In terms of weight and lightweight design – especially in the context of avoiding CO2 emissions – we’re pointing out a few approaches that will hopefully find their way into future road-going vehicles – like in the case of the first TFSI for Le Mans and the TDI.”
The 2019 season begins on 4 May at Hockenheim.
Growing up on a diet of World Rally Championship highlights and lengthy Gran Turismo 2 sessions, a life in cars was as good as inevitable for Matt.

This is actually so cool how they have engineered a 4 cylinder to create more horsepower than a v8
OwO
I need this
RIP cooling system
:O
does it fit in my honda?
They should stop TORTURING aliens
In 10 years time, there will be a 0.8L two cylinder that produces 1000 hp
There’s no replacement for displacem… Oh wait, yes there is.
I feel like DTM (and other series) should go towards electrification rather than downsizing
E.g. rather then ditching V8s in favour of inline 4s, why not make hybrid V8s?
✅ Sound stays as good as before
✅ Fuel efficiency increases
✅ Power output increases (although there is a weight penalty)
✅ More R&D into electric drivetrains that may trickle down to road cars (at this moment in time this is more valuable than R&D in downsized engines which is already high)
