Well to answer that it’s pretty damn awesome , and I’ll explain why. Covering thousands of miles a year can be a fairly laborious process with little engaging or entertaining about it. I’ve daily driven 3 RS4s now , one b7 saloon one b5 avant and this charged avant. They’ve all been very good at providing a fun factor to my trips and outings no matter how routine they might be. Possibly the strangest thing to comment on is the fact fuel consumption is no worse than my naturally aspirated saloon if anything at times it’s better. I think what this car does best is exude class, with it being Daytona grey it’s subtle and good at lurking in the background when you just want to get home after a long day. Despite the wingback bucket seats being specced this car is incredibly comfortable for a motorway jaunt and the RNSE satnav I still find every useful. Cruise control and heated seats just add to the experience as a warm backside is never a bad thing on a cold winters morning. But what we all want to know about… is this car daily drivable ? And the answer I’m happy to report is yes and it fits the bill perfectly. It’s effortless power allows you to surge past near any obstacle you may encounter with the simple drop of a gear and a moment of lead foot. You’ll be pinned back in your seat and roar past Deborah in her diesel Passat stuck behind the lorry you’ve just launched past like a ballistic missile. The standard 8 pot brakes cope remarkably well with the extra grunt but upgraded pads are strongly advised. You’ll need them should you catch yourself above the speed limit. Ceramics would be better, I had a set for a short while and they were fantastic but that’s a story for another day.
Servicing is where things start to differ from your oem RS4. your long-life service schedule just won’t cut the mustard here. Oil changes are advised every 5000 miles with plugs being done every 10000 miles. A detonation of any maintenance parts at this sort of power will no doubt destroy your engine. Carbon cleaning is said to not be required , my car has been supercharged now for 91k miles and is till producing 613ps 656nm , would a carbon clean maybe a produce an extra 5-10ps? probably. But is it worth the large cost? Not at all. Tyres become more consumable than usual I think simply because of the speeds you’re now able to accomplish so easily you’ll find yourself braking harder and entering corners just that bit faster. There are much faster ways of changing gear but is there anything more satisfying than the blip of the throttle as you rev match down through the gears…. I don’t think so.
Warming up and cooling down of these cars is essential even more so when they’re supercharged. They can take some punishment once they’re hot but mechanical sympathy is essential for longevity. Something I’ve found useful during day to day life with the supercharger is octane booster. I run Millers its only £15 for around a litre and it gives you 10 tanks worth of boost , only a RON or two but more is more and I like to think it helps to keep things running well. Water-methanol injection is another advised after-market part for the safe running of these forced-induction cars. Lowering intake temperatures and increasing the octane levels the car will not only run cooler but create more power as a side product, so a win win. But other than the fact it’s a 13 year old estate car with a manual gearbox and 200bhp more than it left the factory with. It’s just a grey estate so there’s loads of room in the boot for whatever you may need to chuck in there , it’s comfortable it’s kinda quiet (100 cel downpipes and a non resonated Milltek) it’s pretty much the ultimate daily driver.
