2013 Audi RS5 Cabriolet

The Audi RS5 is a bit of an odd duck in the brand's US lineup. At the moment it is one of only two RS models - the other being the TT RS - atop a pyramid of A and higher-performing S models. It is not, however, the brand's flagship performance model - not even close - that space being occupied by variants of the R8 supercar, specifically the V10 and GT models, and upcoming 560-horsepower RS7.
The RS5 does, however, owe its beating heart to those ten-cylinder R8s, its own 4.2-liter V8 almost identical to those engines save for two fewer cylinders. Outside of the R8, then, the RS5 is the lone bastion of naturally aspirated V8 power in a brand that once happily shoved 4.2-liter V8s under any hood that they would fit. Today, not even the giant Q7 SUV offers a V8. Lastly, the RS5 is not new, except to us, having been on sale in Europe in coupe form the last couple of years.
While Europeans were able to enjoy the hardtop two-door without us, the RS5 Cabriolet is reaching both peoples around the same time: now. We reviewed the RS5 coupe just recently, and having spent some time with the tin-top model myself as well, here is my take on the droptop version of what I consider one of Audi's most interesting models.

Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.

Porsche would have entered F1 if Audi had blocked its Le Mans program

Go back a few years and you may have heard rumors of Porsche heading into Formula One. That never came to pass - or at least, it hasn't yet - but that doesn't mean that it wasn't close to happening. That's how committed to returning to top-level motorsport competition Porsche has become recently.
Autosport reports that just as Porsche was merging fully into the Volkswagen Group, Zuffenhausen was weighing its options for a factory racing program. Le Mans was its favorite, which makes sense, as it remains far and away the most successful constructor in the history of the famous endurance race. But the strategists at Porsche were worried that its new corporate overlords at Volkswagen wouldn't support two LMP1 programs and would favor Audi, which has positively dominated the modern era of endurance racing, coming second only to Porsche in the number of Le Mans victories it has scored to date.
Porsche's Plan B was reportedly to head into Formula One, although it isn't clear if the German automaker was intent on starting its own team, buying an existing one or merely providing engines to other teams. Porsche fielded its own cars in F1 in the late 1950s and early 60s, and returned as an engine supplier with TAG to power McLaren in the 1980s, powering Niki Lauda and Alain Prost to the World Championship in 1984 and 1985.
