Diesel replaces V8 in new Audi S6 and S7
Ingolstadt ditches petrol in favour of electric-powered compressor tech
Just when it looked like diesel might have died a death as far as performance cars are concerned, Audi - and, by extension, Volkswagen - have made it clear that they still see life at the end of the oil-burning tunnel. Having already introduced a V8 TDI Tourareg and diesel SQ5 (again), Audi has revealed a new S6 and S7 that will be powered exclusively by a 3.0-litre TDI.
This being a 2019 diesel Audi though, it’s not your regular oil burning old nail. Like the SQ7, these S models use an electric powered compressor, which responds in 250 milliseconds to provide a boost at revs up to 1,650rpm. Essentially it’s there until the exhaust turbo is up to speed: “The EPC supports the TDI’s turbocharger whenever there is insufficient energy in the exhaust gas for spontaneous torque buildup – when starting off or accelerating at low load, from a low engine speed” is how Audi describes it. Working in conjunction with the regular turbo – Audi rather confusingly calls it ‘dual supercharging’ – the EPC provides the S6 and S7 with 516lb ft from 2,500-3,100rpm. Essentially, therefore, it’s a lot like the SQ5 installation. Or sounds like it, at least.
Unlike the SQ5, but along similar lines to the SQ7, these cars use the 48v mild hybrid system with belt alternator starter and lithium ion battery. The former can recover up to 8kW of power when the car is slowing down, storing energy in the latter. Audi claims the technology allows for start-stop operation from 14mph, and a fuel saving of up to 0.4 litres (presumably per 100km) in “real driving conditions.”
All together, Audi says the S6/7 powertrain is good for 349hp, meaning five seconds flat to 62mph for the S6 saloon, or a tenth more for the S7 and S6 Avant. The important efficiency numbers range from 43.5-45.5mpg and 164-171g/km depending on model and wheel size.
Keeping up? Good, because there’s a little more. Like all S Audis, these S6s and S7 use quattro with a self-locking centre diff (and up to 85 per cent of the power going back), but there’s a brace of firsts as well: adaptive air suspension hasn’t been seen on an S model before, and is available here as a “comfort-oriented alternative” to the standard 20mm lower sports set up, and there’s all-wheel steering as an option, too. Audi says the technology, working in conjunction with dynamic steering, makes the cars “more manoeuvrable and agile at low speeds, and provides more directional stability at high speeds when changing lanes.” Seems a little superfluous for cars that will never leave the outside lane, but there we are. Those new inclusions join the familiar sport diff, optional ceramic brakes and drive select in the S6 roster of dynamic tech.
It’s business as usual for the styling, too, the S6 and S7 identified by four exhausts, silver mirrors, a new grille and larger – 20-inch as standard, 21s as an option – wheels to mark them out as something a little racier.
Audi will launch the S6 Saloon, S6 Avant and S7 Sportback this summer, with prices kicking off at 76,500 euros in Germany – expect UK prices shortly. Interestingly, these new uberdiesels will be Europe-only, too - the US, Asia and Middle East get the RS4’s 2.9 TFSI petrol with 450hp. Curious. Still, don’t be too disgruntled – the RS6 isn’t far off, either, and one or two V8 S6s are available - this 2018 saloon is barely run in, and already less than £40k...
40mph on 30mph roads and complain when they get done for it.
45mph on national speed limit roads and complain when they get overtaken.
I'm convinced that most drivers don't know what the national speed limit sign means.
Don't you dare have your own opinion!! You cannot be considered a car fan, and certainly not have a 'warm model' badge on your car if you drive a diesel, irrespective of your mileage and circumstances. You should buy an 15yr old MX5 and bask in it's gloriousness.
Perhaps save the sweeping generalisations for another website?
The quad exhausts aren't even real. They are completely, totally fake. It's just a piece of plastic trim that's totally blocked off.
Go and look at spy shots of these cars testing in camo in the Arctic for proof if you don't believe me. Quad 'exhausts' filled up with ice and snow.
WTF is going on?!
Perhaps save the sweeping generalisations for another website?
But the 'b
ks' element was the assertion/insinuation that anyone that can afford such a car can afford fuel regardless/is unconcerned with fuel consumption. Have you ever made a post without immature stereotypes in? Or have you recently been turned down for a photocopier repair management position?
What other logical reason is there for turning one of their performance models into a Sooter?
As for your comment about stereotypes, cars are sold into markets by stereotyping their average buyer. In this case a man with pointy shoes and a blue suit called Gavin.
You've got to get this correlation between leasing and being stretched financially out of your head. It can be quite the opposite if the cost of leasing is less than depreciation, which is often the case.
Do you have data to prove this is not the case?
