Mercedes-AMG E63 S vs Audi RS6 Performance
Four tonnes, 1,200hp and more than £200,000 - super estates get really silly, but which is best?
Why no mention of Mercedes-AMG yet? Well in terms of everyday usability, gigglesome though the old CLS and E-Class were, 585hp and two driven wheels didn't always ensure the smoothest progress. Great if you wanted to lout about, not so suitable for Sunday visits to the in-laws.
Of course AMG now offers fast families the best of both worlds, with an all-wheel drive E-Class wagon that can also play the tyre smoking hooligan if required. In fact the similarities to the RS6 are uncanny, further proof if it was required that the Audi is the car to beat: both have twin-turbo 4.0-litre V8s, both have more than 600hp and both allow the driver almost infinite configuration to deliver their perfect uber wagon. Place your bets...
The day begins in the E63, because Nic really likes an RS6 and isn't someone to upset before 10am. No bother, because the Mercedes is excellent. Better perhaps than the saloon we drove recently, and not simply due to the practicality perks. It might be a placebo, but the ride of this estate - one of the chief bugbears of the saloon - does feel fractionally less punishing. It's still tough, it's still a bit irksome sometimes, yet here it doesn't seem to get in the way as much as before. Could it be the optional ceramic brakes taking a tad off the unsprung weight?
Whatever, above urban speeds it doesn't take long for the E63 to work its magic. Combining fantastic luxury with absurd performance is an AMG tradition that stretches back decades, an obligation the E63 happily (and hilariously) fulfils. The difference here is a dynamic intensity that these big Benzes have previously lacked, a tenacity and coherence that's fairly shocking in all honesty. The more aggressive modes are redundant on the road, yet the devastating speed and precision are clear - the E63 has already set a very high standard even before the RS6 has turned up.
Then the Audi arrives with Nic at the wheel, broad shouldered, angry and intimidating. The RS6 also looks fantastic. There's a level of menace and a presence with the Audi that neither the passage of time nor the Mercedes parked next to it can diminish. Uberholt prestige may have little relevance in the UK, though we can be grateful that it has created such a cool estate.
'Charismatic' is a word that comes up a lot when discussing the big, fast Audi. Not only is that a phrase seldom used to describe a product with four rings on its grille, it's often a euphemistic term applied to cars with lots of power and little else going for them.
Here, it applies in every positive sense, the RS6 delivering on the V8 muscle car thunder potentially even better than the Mercedes, and complementing it with genuine dynamic prowess. It's not the last word in communication, the RS6, though that's arguably of limited relevance with this sort of car; what there is, however, is an accurate, capable and enjoyable fast Audi.
It rides with decent suppleness, controls its weight well and the sport differential makes the big old lump more neutral than you might expect on corner exit. Furthermore, older engine or not, this RS6 is still tremendously rapid. And it sounds better; sounds brilliant, in fact.
That the Mercedes raises the bar yet again is not a criticism of the Audi, more a reflection of where AMG has moved the goalposts to. The red car reveals weaknesses in the blue one you simply hadn't recognised before: a slight mushiness to the throttle response, the tiniest delay in gearshifts, occasional lapses in body control. By any other measure the Audi is great in these areas, and it's only this test that has brought those deficiencies - and even that seems too harsh a term - to light.
There's a distinct Nissan GT-R vibe to the way the E63 drives, and that's meant entirely as a compliment. Even if it does begin with the graunching and grinding of diffs at parking speed. There's that unrelenting and underlying firmness, yes, but also this sense of ceaseless twin-turbocharged speed and unflappable composure. There's traction, control and poise that you wouldn't have believed possible in something this large, and a balance to the 4WD system that enhances rather than detracts from the experience. After that, the Audi starts to feel a tad laboured.
The Mercedes has everyday advantages too, the interior more stylish and the engine more efficient. It's not even significantly more expensive either: £4K at list price becomes more with these two particular cars, but with the brakes and the carbon off the AMG they're level. At £98,000, yes, but level all the same...
Comparing a car that's been on sale since 2013 with a brand new one launched this year will always prompt calls of foul play, but when a rival is such a perfect fit the comparison has to be done. That the RS6 still comes out of this test with its credibility intact shows what an accomplished, likeable car it remains; declaring it the loser in this test seems deeply unfair, and even second seems to sell its achievements short.
In the company of this Mercedes though, that's how the result must read. It's an unequivocal victory for the E63, and it was never in much doubt. It's an astoundingly complete car, offering an armoury of talents with which even an RS6 can't meaningfully contend. This is one of the best AMG products ever, the engine tweaks delivering a level of excitement over a C63 and the interior a sense of opulence not that far off an S-Class. Previously that would have been sufficient for a deeply endearing fast Mercedes; that the E63 now also offers a formidably strong dynamic repertoire secures its place as the best super estate around, and confirms AMG is in a richly exciting vain of form.

I would gladly take either of them home but am still slightly biased towards the Audi. One thing I never quite understand about some of the AMG products is the nice big swollen wheel arches up front and nothing at the back - looks very mismatched.
Thing was - as an ownership proposition the Audi was always the better choice. They were nicer places to sit and you could use them every day of the year, anywhere you liked thanks to 4WD and their less edgy nature.
So I have to conclude that MB steeping-up with 4WD and nicer materials etc. actually moved the game towards Audi rather than away from it!?
The real issue is that these cars are just too-bloody-big and the real interest for drivers wanting some practicality exists in the A4/C bracket anyway (which you can now get dog crates into!!)???
And seeing as bmw seem to ignore this niche completely (and at heart I'm a Bayern man) I'll just have to keep my e61 M5

We have a Jaguar XF diesel s with the 8 speed auto. It's too busy changing gears to take advantage of the near 400lb.ft. of the V6. Took a test drive in an earlier version and the old 6 speed seemed a far better match for the engine. The mapping for the 8 speed is frustrating for going a bit quickly
Have had a 4 cylinder XF for a day (with the 8 speed) and that made more sense as a match to compensate for the engine's limitations.
In any version of the 8 speed, best forget about manual changes - for me at least, too many to choose from or my little brain.

I just mentioned diesel. The UK government has now launched cruise missiles at my house due to me, thicko, thinking that would reduce CO2 whilst giving me a longer range between fill ups. How many stops for petrol will these two bad boys do on a trip from Glasgow to London used as meant to be? 2? 3?
5?
You need a car that can take you trans UK with only one stop for the service station where they have the special half price offer on a Ginsters peppered steak slice. End of story.
