Audi RS6 Avant and Mercedes-AMG E63 S drag race for Top Gear

Sometimes the kids are late for school, and you need a wagon to get them there in a hurry. In its latest drag race, Top Gear finds out which is the quicker high-performance family hauler: the Audi RS6 Avant or the Mercedes-AMG E63 S. The specs suggest this race should be quite close at the finish line. The RS6 has a 4.0-liter twin-turbo V8 with 552 horsepower, but the E63 S is a little more powerful with 577 hp from a 5.5-liter twin-turbo V8. However, the Audi has a traction advantage from the all-wheel drive system, whereas the Mercedes only spins its rear wheels. Pick your favorite, and then watch the video to see if the similar numbers translate to a photo finish in the real world. Related Video:

Audi prepping A5 Sportback for US market

Audi is prepping one of its European-market models for the US market. No, it's not the RS3. Or the RS6. Or even an RS model at all. Sorry. Instead, just be happy we might be finally seeing the handsome A5 Sportback on American roads. Automotive News is citing Audi of America boss Scott Keogh, who hinted that a third A5 body style would be offered in the very near future. And since there are only three A5 body styles – coupe, convertible, and Sportback – and Americans can already buy the first two, the five-door variant is almost certainly what he was referring to. "I feel confident that there will be another variant of the A5 that will be a real home run," Keogh told AN during the US launch for the new A4. Keogh then went on to make the same argument we made above, that Audi only has one more A5 body to sell over here. Audi sells the Sportback with a number of powertrains in Europe, including gas, diesel, and S performance varieties, but we'd expect the US-spec model to mimic the new A4. That means the only choice facing owners would be whether they went for front- or Quattro all-wheel drive. According to Automotive News, we can expect some kind of announcement on the A5 Sportback ahead of the second quarter of 2017, when it's expected to go on sale. We're impatient, though, so we reached out to Audi for confirmation. As soon as they respond, we'll update this post. Related Video:

The real reason Audi races

The world has watched Audi have its way with endurance racing since 1998. What started as an intriguing race winner in 2000 that could be rebuilt so quickly that the ACO oversight organization changed the rules to slow Audi mechanics down, slowly morphed into a unique assassin, employing novel engineering methods to achieve series domination with its R18 E-Tron Quattro. Until recently. It's strange, then, that for all these years we didn't fully comprehend Audi's stated approach to motorsport. And so we sat down with Dr. Wolfgang Ulrich, head of Audi Motorsport, and Chris Reinke, head of Le Mans Prototype development while in Austin, TX, for the Lone Star Le Mans and World Endurance Championship race for answers. BMW, Corvette, Porsche, and Ferrari have healthy reputations, lucrative option sheets, and supported a robust trade in special editions by winning races. They have standalone racing divisions and they transfer the entire sheen of their racing endeavors to their road cars, a healthy part of what their customers buy into. Even though we know they improve their road cars with lessons learned racing, the belief is that they race because that's just what they do; those brand names mean racing. "Not one single euro is spent on a separate motorsports program." Yet Reinke said that for Audi, "Not one single euro is spent on a separate motorsports program. We [Audi Motorsport] are part of the Technical Department [of the road car company]. We are a pre-development lab for road-relevant technology." As in, Audi isn't racing out of core philosophy, it's racing only to improve its road cars. That helps explain why Audi's entire road car lineup doesn't bask in the same racing aura as those other brands even though Audi has been racing since it was called Horch. It's not a racing brand, it's a technology brand. Said Ulrich, "Instead of components, look at technologies – not lights, but lighting technologies, not engines, but engine technologies, like injection pressure technology is the same from the race car to the road car." That's nowhere near as exciting as, "Win on Sunday, sell on Monday," but it is arguably much more practical. Quattro is the most obvious example of racing tech for the street. For a less obvious one, Reinke said, "Audi Motorsport developed codes for computational fluid dynamics, and then we'd run the calculations on the Technical Department computers at night.
