The 2018 Audi A5 and S5 Cabriolets are here just in time for winter

There are no big surprises with the 2018 A5 and S5 Cabriolet. As you'd expect, the convertibles share a design with their coupe counterparts, the A5 and S5 coupes, refreshed versions of which were unveiled earlier this year. Alongside the coupes and upcoming sportback models, the Cabriolets complete the A5 lineup. At least until another RS 5 comes along. In Europe, the A5 will have five available engine options, including three TDI engines maxing out at a 286-horsepower 3.0-liter, and two TFSI gas engines, with the most powerful putting out 252 hp. There will also be a choice of three transmissions including a six-speed manual, a seven-speed S-Tronic dual-clutch gearbox, and as an eight-speed automatic. For the US, though, the powertrains should be the same as the new coupe's, with a 2.0-liter turbocharged four-cylinder generating 252 hp and 273 lb-ft of torque in the A5, replacing the 220-hp turbo four in the previous model. An eight-speed automatic is a definite, although the existence of a manual A4 sedan for our market leaves some hope that a six-speed could be available in the A5 Cabriolet or at least the coupe. Audi also hasn't made final decisions on whether a front-drive model will be available here as it has been in the past. View 13 Photos The S5 Cabriolet, just like the two-door model, uses a new 3.0-liter turbocharged V6 engine that produces 354 hp and 369 lb-ft of torque, which is 21 more horsepower and 44 more pound-feet of torque than the old 3.0-liter supercharged V6 made. Despite the bump in power, the new S5 Cab hits 62 miles per hour in 5.1 seconds, just like the previous model. It is again electronically limited to 155 mph. And like the coupe, it will use an eight-speed automatic and get Quattro all-wheel drive standard. The A5 Cabriolet loses roughly 88 pounds compared to the previous model. The cars use an updated five-link front suspension and Audi claims the chassis is 40 percent stiffer than before. The soft tops have more insulation to cancel out road noise, take 15 seconds to open, and 18 seconds to close. You can do either at speeds up to 31 mph. The A5 Cabriolet will be available with Audi's latest array of driver assistance systems, including its navigation-linked adaptive cruise control and collision avoidance assist. A seven-inch display, seat belt microphones, Audi's Virtual Cockpit infotainment and gauge package, and a head-up display are available on the inside.

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.

VW execs didn't think diesel problem would be so serious

Volkswagen Group has admitted that former chairman Martin Winterkorn received two memos about the diesel scandal in 2014. Top execs ignored the problem because they didn't think it was a serious issue. VW disclosed these details to counter allegations in a German shareholder lawsuit that alleged the automaker violated the law by withholding the info from investors. A memo on May 23, 2014 first advised Winterkorn about emissions cheating. A memo on May 23, 2014, first advised Winterkorn about the study from the International Council on Clean Transportation, which identified the emissions cheating. According to VW, the document was part of the exec's weekend mail, and the company's investigation didn't discover whether Winterkorn actually read it. A rumor last month alleged this memo existed. Another memo for Winterkorn on November 14, 2014 was about several defects, including the diesel engines. The document estimated it would cost 20 million euros ($22 million US at current rates) to fix the problem. The chairman learned about the issue again on July 27, 2015, during a meeting on product issues. "Mr. Winterkorn asked for further clarification of the issue," according to VW's statement. Things got serious at the end of August 2015. Things got serious at the end of August 2015 when technicians explained the diesel issue to the legal department. VW came clean to the California Air Resources Board and the Environmental Protection Agency on September 3. A memo told Winterkorn the next day, which was also previously alleged. According to this investigation, management didn't believe the diesel problem would affect the stock price, and they estimated the cheating might cost at most a few hundred million dollars in fines. The execs were clearly wrong. The share price dropped after the scandal broke last September, and the problems have started to affect its divisions. According to Reuters, Audi reported it suffered 228 million euros ($249 million) in costs in 2015 from the emissions issue and repairing Takata's faulty airbag inflators. Volkswagen still doesn't know the exact costs of the scandal, but the automaker's law firm, Jones Day, plans to release a report in the second half of April to explain the whole affair. By that time, we might also know how VW plans to fix the problem because a judge recently gave the company until March 24 to outline a fix for the 2.0-liter TDI. CARB started evaluating a repair plan for the 3.0-liter TDI in early February.
