An amazing Group B rally car collection heads to auction

Kicking off in 1982, the Group B era spawned some of the most fearsome rally cars of all time. The technologically advanced pioneers of all-wheel drive and turbocharging defined a time when automakers had carte blanche to build machines with unrestricted power, without the burden of homologating a large number of road cars to qualify. The results were sometimes deadly, leading the FIA to ban the class after 1986. Now, a collection of seven Group B monsters is headed across the block in Paris as part of the Artcurial auction, held in partnership with France's famed Retromobile show. The show has been delayed to June, however. There's a 1985 Peugeot 205 Turbo 16, one of 20 Evo II models that helped the company achieve two championships in Group B's short run. This particular example was driven by world champion Timo Salonen at the 1986 Swedish Rally, where it finished seventh due to an oil filter seal failure. Bruno Saby subsequently drove it at the 1986 Tour de Corse and Peugeot entered it at the 1986 Acropolis Rally as well. It's still registered to Peugeot Talbot Sport and represents a French technological achievement, according to Artcurial, comparable to the Concorde or TGV train. Representing Italy are a pair of Lancias in the iconic Martini livery. The Lancia 037 helped Bel Paese clinch its only Group B victory in 1983, after a hard-fought rivalry with Audi. It's one of the few Group B cars that weren't AWD, achieving its success the old-fashioned way, through lightness and superb handling. A second Lancia, a 1986 Delta S4, was the culmination of the Italian firm's later Group B efforts and one of Saby's favorites. While Group B was no more in 1987, the S4 was the predecessor to the Delta Integrale that would dominate WRC from 1987 through 1992. While the collection also includes greats like a Ford RS200, Renault 5 Maxi Turbo, and MG Metro 6R4, the centerpiece is the Audi Quattro Sport S1. The ultimate Group B machine, it introduced all-wheel-drive and turbocharging to the sport. It also employed the wildest use of wings and air dams to generate downforce. Tunable up to 590 horsepower, it could rocket to 60 mph in about three seconds. The car offered for sale came straight from Ingolstadt, a 1988 model built for the Race of Champions of ex-Group B cars. The collection was amassed in the late 80s and early 90s, not long after Group B's dissolution.

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.

Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.
