The RS4+ is a 530 hp ABT-Tuned Winter Sled

My love for fast wagons is no secret. They combine various attributes you really want; interior space rivaling some big SUVs, performance rivaling some serious sports cars, and looks rivaling some long sleek missiles on wheels. This one is no different and, being a fast Audi wagon, it's also AWD for year-round fun. This is a bit bittersweet, of course, because of such vehicles as the B7 S4 and RS4 Avants which had magnificent 6-speed manuals and 4.2 litre naturally aspirated V8's. But let's focus on the bright side. There's a 530 hp version of the current RS4 Avant/wagon.

It's based on the Audi RS4 Avant (wagon) which we unfortunately don't get here in North America. As an Audi-backed DTM racing team, ABT Sportsline is no stranger to fast Audi's, and is actually intimately familiar with the RS4 Avant in particular, having already offered the RS4-R last year. ABT says that the demand for the RS4-R far exceeded the limited 50-car run they offered (no surprise there) so they are offering the RS4+ for those who came away empty handed.

Thanks to ABT's own separate computer control unit, every RS4+ will come with "at least" 510 hp. For those that hunger for more power, an optional ABT Power S package brings an upgraded water radiator kit and circulating pump as well as upgraded exhaust, which will be good for 530 hp. I would definitely get that package because, well, it's more power and the added cooling would come in very handy on a track day with that much power.

ABT estimates that a standard RS4 is good for a 0-60 mph run in 4.1 seconds, and their "standard RS4+" with 510 hp is good for 3.9 seconds. But when Car and Driver magazine tested a standard US-spec RS5 with 444 hp, it did 0-60 mph in only 3.5 seconds, so expect this to be even faster.

To make sure there is better handling to go with more power, the RS4+ also comes with modified height-adjustable springs and dampers with help from suspension supplier KW. Or for a little extra, you can get an automatic height-adjustable air-suspension like you get on a Mercedes AMG E63 S. The rear anti-roll bar is also upgraded for sharper turn-in and more neutral handling.

Rounding off the performance upgrades is a host of exterior modifications, some are aerodynamic and functional. All of them are rendered in carbon fibre, including a front lip spoiler/splitter, front blades/cunards, grille surround/frame, rear spoiler, and side skirt. Expect also a spattering of RS4+ logos inside and outside.

All of this will cost €28,900; the equivalent of $32,860 USD. That's on top of the price of an RS4 Avant, of course. Or, if you want the extra bit of power and air-suspension, you'll have to pay €4,490 ($5,105 USD) for the engine upgrades and €1,590 ($1,808 USD) for the suspension. The closest thing to it to the RS4 here is the RS5 Sportback, which carries an MSRP $75,195 USD, meaning it would cost over $110k when all is said and done, a little more than the starting price of an AMG E63 S Wagon with a proper twin turbo V8, which also comes with AWD.

The RS4 is sure to be lighter, likely by 500-600 lb. and will likely feel that way. How much is that worth to you? You do get peace of mind as ABT is confident enough to offer a warranty in certain European regions, up to 2 years and 100,000 kms from first registration. If you want one, make sure to head over to ABT Sportsline immediately since they are only making 50 this time around as well and they likely won't last.

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

How would a Mustang 3.5L EcoBoost compare to the 5.0L V8?

Ever wonder how a 3.5 litre EcoBoost might fair against the 5.0 litre V8 in the Mustang? Of course you have. Ever since Ford dropped it in the F150 (and perhaps well before), everyone has been wondering how it would perform. There are basically two camps; those who think it would be awesome because of tuneability and power potential and those who think it means the death of the V8 in the Mustang. If you are in the latter group, we seem to be good so far with continuous upgrades to the 5.0 litre Coyote and the brand new Shelby GT500 which still uses a supercharged V8 as it has been for over a decade and multiple iterations. But what if... Well, it seems we are closer than ever to finding out the answer to that question. American Trucks recently got together two crew cab, short box, 4x4 F150's but one has the 5.0 litre V8 and the other has the 3.5 litre EcoBoost V6. There has been a few comparisons between 5.0 litre and 3.5 litre EB F150's, but this seems to be the most di

Bridgestone Potenza RE-71R Track Review

2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are: 1. They grip as well or better than most R comps. 2. They don't wear as quickly as R comps if driven occasionally on the street. 3. They work better in the rain than R comps. The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine. In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman
