We're now over 3,000 miles into what is already one of the best everyday car experiences I've enjoyed. This is the last time I'll mention the unintelligible differences that exist between this and the smaller RS4, but the more I drive it, the more I hope Audi RS's Franciscus van Meel was part of the team that preferred the extra comfort and usability of the RS6. If so, BMW's gain really is Audi's loss.
I am an unashamed F10 M5 fan, but the RS6 is just more usable and, heading into winter, it will only become more so. It is also damn near as good fun to drive, and in many ways the more complete package.
What is the role of this type of car in one's life? Many people think it's just a complete waste of time - too expensive and barely any real-world faster than the briskest turbodiesel wagons. Wouldn't you just have a 535d? And so on. If you could afford this car, I can't see why you'd want anything else. It is crazy fast, but really does look quite innocuous to the casual bystander. Is it really that much quicker than some torque-monster with 'd' in its badge?
The other accusation is a lack of excitement. Which I find odd. I don't want my everyday car to be some whinnying lunatic, I want it to be relaxing and comfortable and have a killer hi-fi. And then when I want to blitz past something, I want the motive force of Saturn 5 to thwack me into the near future.
This car's perfect role is getting to places fast, with the minimum of fuss, regardless of conditions, and attracting as little attention as possible. You wouldn't ever seek out a wriggly B-road for the sake of it, but when you do find yourself on one the car is just so damn fast and capable. This one runs the sports suspension which isn't the fancy air-supported version and I think it's the best road suspension in the class. For someone like me to say that about an Audi is a bit strange. Even the lovely E63 wagon can't match the Audi's balance of ride comfort and support.
There is a proviso to this and it comes if you try and drive very fast. Then the car does begin to lose some control, but you really shouldn't be driving that fast on the road anyway. And if you buy an RS6 to do track days then you probably have a Morgan 3-wheeler for long journeys.
My brain is just about tuned into the MMI system - but I still don't find it as intuitive as the Merc equivalent. Furthermore, there's no USB socket for charging your phone and the Audi media interface cable supplied with the car is for an iPhone 4. Why is it the motor industry simply refused to acknowledge the new iPhone 5 connector? First world problems and all that. Sometimes the Bluetooth connection goes south, and you can't reconnect in the telephone mode, instead needing to reconnect the device as a telephone, and then switch back to the media function. Are you still awake back there? I'm trying to be objective here!
The front seats are very, very good - and they adjust low enough which isn't always the case. Rear room is generous and despite the rear glass having more of a slope (no complaints to the BBC please) than the E-Class wagon, the boot is still vast. Two mountain bikes fit easily with the seats folded flat.
And there's a slight powertrain coarseness that's crept in over the past few days. It doesn't feel like a wheel inbalance, but I suppose it might be. There's a slight thrum at a fast cruise and under full power you can sense something isn't quite balanced. I shall investigate further.
As for the cries of '£100K for an Audi estate car, you have to be joking!!', well, I've been trying to think of another car that could cover the same roles, and there just isn't one. The fact that most people assume it's just a normal A6 driven by a bloke who was too mean to pay for metallic paint adds to its appeal. Easily the best Audi I've driven, and the best car in its class.
