2015 Rolex 24 at Daytona pre-race notes

Reigning Indy 500 champion Ryan Hunter-Reay summarized our feelings on every year's Rolex 24 Hours at Daytona when he said, "The 24 kind of kicks off the year and has become part of my calendar... It definitely helps you get in race shape after a long layoff." Speaking of IndyCar drivers, 14 of the 33 pilots who started last year's Indy 500 are driving in Daytona this year, and an IndyCar driver has been part of the overall winning team for the last four years. The race starts at 2:10 pm Eastern Standard Time, here's where you can watch it: 2-4 pm: Fox Sports Network 4-8 pm: Fox Sports 2 8-10 pm: Fox Sports 1 10 pm-7 am: IMSA TV on IMSA.com - commentary available here for the full 24 hours 7 am – 2:30 pm (Sunday) – Fox Sports 1 Timing and Scoring Andy Blackmore's typically awesome Spotter's Guide Video primer on the four classes: Prototype (16 in this year's race), Prototype Challenge (8), GT Le Mans (10), GTD (19), and how to identify them. Daytona International Speedway: tri-oval with an infield road course, 3.56 miles long, 12 turns Entry list Qualifying results We've tagged along with Audi for the 53rd running of the race, which marks the first event in the Tudor United SportsCar Car Championship. After a difficult first year of teething – IMSA president and COO Scott Atherton said, "Everybody on our staff and everybody that raced with us last year would tell you it was the most challenging season on record" – some things are smoother this year, some things aren't, starting with the field: 53 cars are expected to line up, 14 fewer than last year, the smallest field since 48 cars lined up in 2011. The Prototype class shed three teams from 2014 and the GT Daytona class lost ten, so there's a 19-car field in that class (nine Porsche 911 GT Americas, three Ferrari 458 Italias, two each of the Aston-Martin V12 Vantage, Dodge Viper SRT, Audi R8 LMS, and one BMW Z4). Truth be told, last year's number was probably inflated by having the previous American Le Mans Series and Grand-Am Rolex Sports Car Championship combined to make the USCC; the field in 2013 was 57 cars, in 2012 it was 59 cars. Another factor in this year's race is that the GT class adopts FIA GT3 rules from next year. Brad Kettler, manager of Audi's customer motorsport program, said they'd sold five R8 LMS cars last year but zero for this year – there are undoubtedly teams waiting on the sidelines for the rules unification before spending the money.

Audi Sport Quattro Concept to spawn volume sports car?

There have been two modern re-imaginings of the original 1984 Audi Ur-Quattro: the Quattro Concept of 2010 (shown above) and the Sport Quattro Concept revealed at the 2013 Frankfurt Motor Show. In between them, there have been numerous rumors about what, if any, kind of production car Audi might make of them. According to a new report in Auto Motor und Sport, Audi CEO Rupert Stadler has "indicated... that the car will come," and based on the specs presented, what we get might end up being a mix of the two.
Ulrich Hackenberg, Audi's head of R&D, apparently wants a sports car with wider appeal than the 700-horsepower hybrid Sport Quattro Concept. AMS says his vision would be built on a modified A6 platform - the same MLB architecture under the Sport Quattro Concept - with ample use of carbon and aluminum keeping the weight down to around 1,300 kilograms (under 2,900 pounds). Engines could include a 2.5-liter, five-cylinder (like that of the original, smaller Quattro Concept) offering anything from 310 to 360 hp. Those numbers would be at least 48 horsepower shy of the first concept, but a less-powerful entry point to a new model range would provide a lower cost of entry. Besides, a full model range would likely include a significantly healthier powertrain option on the top end.
At the moment, Hackenberg is said to be unsatisfied with the design of the car, which could well mean we'll get another concept car before a production version appears.

2017 Audi A4 Deep Dive

Unchanged. Plain. Boring. These words have been used to describe the new 2017 Audi A4, but they all miss the point entirely. Yes, the design of the new A4 is evolutionary, rather than a ground-up restyling. But as they say in ancient High German, "If it ain't broke, don't fix it." Of course, if you're at all interested in the 2017 Audi A4, you've probably read all about it in the official press release a few days ago. So we'll cut to the chase and tell you the bits you don't already know: the American-market details. We spent a day at Audi headquarters in Ingolstadt last week finding out the latest and poking around the A4 in the metal. The new A4 is wider, longer, and roomier than before. The lines are crisper and sharper, but yes, the proportions have remained very similar. That was done on purpose, thoughtfully. Not out of laziness. Stand any two sequential generations of Porsche 911 next to each other and you'll find they are rather similar. And yes, people do complain about that. But they also complain about the property tax rate on their third home in Monaco. That familiar-looking body gets a shockingly low coefficient of drag of just 0.23. The improvements in drag come from fine-tuning details down to the placement of the side mirror (now on the door, rather than the triangular window panel) and the contouring of the inner edge of the side mirror, which gets little vortex generating bumps to improve the turbulent airflow in that area, reducing drag. Attention to detail and refinement of a successful design – not boring, lazy repetition. Another notable departure in the styling of the new A4 is equally subtle, but even more significant from a precision manufacturing perspective: the hood has no cut lines on its upper surface. Instead, the hood now wraps around the tops of the fenders, the cut line integrating with the sharp crease that runs down the entire body side. The creation of this cut line requires extremely tight manufacturing tolerances to enable the precise alignment of the hood and fender gap with the stamped-in crease in the door panel; misalignment would be obvious and catastrophic to the clean, simple design's flow. Now, let's rip off this Band-Aid: no, we won't be getting the Avant. Why? Because no one buys it, vociferous vocalizations on the Internet aside.
