While Audi's RS models have been getting progressively more powerful, some of its 'S'-badged sporting models have been going in the opposite direction. Take the S6. The third generation 'Type 4F' model which sold between 2004 and 2011 had a Lamborghini Gallardo-derived petrol V10 developing a massive 429hp. That was replaced in 2012 by a 414hp petrol V8 in the fourth generation 'Type 4G'-series model. Seven years later, this fifth generation 'Type 4K'-series car arrived with an output of 'just' 350hp. And you get a diesel engine, though a very impressively-specified 3.0-litre V6 TDI one. Anyway, don't worry: there are compensations. Pulling power this time round rises hugely despite the power output drop - from 550 to a massive 700Nm. So this S6 should prove as quick as its badge suggests it ought to be.
It's tempting to dismiss this S6 on a number of grounds. For Audi owners, it's not as agile as an S4 that would save you plenty. And it's not as fast as the kind of RS 6 that wouldn't cost that much more. And that's before you even start to think about the talented opposition. But as soon as you do, you begin to realise that within its little market niche, this car is something quite special. It's also a very clever contender indeed. Over 35 miles to the gallon from a car that, de-restricted, would probably reach well over 180mph? And at the same time, pulling power that would embarrass most of this model's powerful petrol-engined rivals. So what if an RS6 is faster? Or an M5 or an E63 come to that. This, in contrast, is the stealth bomber of the executive segment, the car that creeps in under the radar. The only one in its sector with diesel drive. And the only one with Audi's S-inspired ring of confidence. Four rings in fact.
