Audi S6 and S7 will have diesel variants - report

we all know this is not real... if it was the case no petrol cars would be built again

@eddie: What you've said is generally true for the 6 cylinnder diesels. The 4 cylinders are still crude -reletatively speaking. The 3.0TDI in the VW Touareg sounds much like the 2.0TFSI when they are both idling side by side, except the 3.0TDI has 'more sounds'.

agree

Here in Europe, we have been running diesels for a long time, and it's well known that we get a longer engine life from diesels. There are a lot of factors making this happen (rpm, heat, lubrication, and so on), but it's proven. I once said I would never buy a diesel, but after driving a Q7 for the first time with a 3.0 diesel, and then comparing to a petrol version, I was sold. The diesel characteristics may not be what every person like, but for me they just made me buy the car. On the fuel economy side, diesel engines are far more efficient (amount of energy extracted per liter of fuel) than petrol engines, as well as there is more energy in diesel. Putting this two things together and figuring out you have more power from less fuel is easy. :) You can read more here: http://en.wikipedia.org/wiki/Fuel_efficiency.

No. The point of the S6/7 is power and performance. 257kW? That's power. It'll translate into performance. And if you've ever driven a high-powered diesel car, you'll know that the sheer amount of torque these diesels make, combined with the power makes for an unmatched 'shove in the back'. It's utterly relentless. Don't knock it till you've tried it, buddy.

Yes...I own a Mercedes E420 CDI 314 bhp and 730 NM so you would think that I know what a diesel engine is all about. The point of having a petrol engine is that it has more responsiveness and you know you can push the revs to the limit and still have some more power, although I doubt it that Audi reinvented diesel engines and somehow managed to improve them in theese areas.
