Audi, McLaren to bring winning cars back to Le Mans

Now gearing up for its 83rd running, the 24 Hours of Le Mans is as much about history as it is about racing forward. So this year, two key outfits in the event's history are celebrating by bringing back the cars with which they dominated in years past. Audi has been a force to be reckoned with and the team to beat at Le Mans in the modern era. It still may not have topped its sister brand and chief rival Porsche's record 16 wins, but Audi's 13 have all come in the past fifteen years since the turn of the millennium. That's one heck of a winning streak, which the German outfit will highlight by bringing every single one of its winning prototypes back to La Sarthe this year. From the R8 that kicked it all off in 2000 through the diesel R10 TDI to the R18 E-Tron Quattro that won last year. Ingolstadt won't be alone in racing down memory lane. McLaren announced it will be bringing back all five F1 GTRs that dominated the race in 1995. The quintet that finished first, third, fourth and thirteenth overall will lead a parade lap around the French circuit, joined by the new P1 GTR that will be making its dynamic debut as well as the customer examples of the special edition 650S Le Mans. What's more, winning drivers from '95 – Yannick Dalmas, Masanori Sekiya and JJ Lehto – will be on hand to participate in the parade lap as well, further highlighting the occasion.

Since 2000, the brand has won the race 13 times. This year, Audi has assembled all of its Le Mans winning models for a group photo for the first time. Every single one of them represents 'Vorsprung durch Technik.' The string of victories began with the Audi R8 in 2000. "Following a year of learning and gathering experience at Le Mans, we started the 2000 season with a completely new design," says Head of Audi Motorsport Dr. Wolfgang Ullrich.

2014 Audi SQ5

No Diesel? No Problem
With the exception of a handful of markets (including the US), the Audi SQ5 was a pioneer for the company's S/RS performance line as it was the first model to wear the badge and also get diesel power. Our general "everything is better with a diesel" mentality was put to the test when we first heard we would be getting a non-diesel SQ5 in the US (despite the availability of the diesel-powered Q5 TDI here already), but as usual we can only blame our federal emissions standards. As Audi tells it, the SQ5 TDI engine would require AdBlue to meet US emissions regulations, and the packaging of such a system just wasn't possible, so the global SQ5's diesel engine was replaced by a gasoline-powered V6 borrowed from the Audi S4/S5. To show that little, if anything, was lost in translation from diesel to gas, we headed to southwestern Colorado to spend an afternoon with the all-new 2014 Audi SQ5.
Our drive program had us taking the SQ5 from Durango, CO to the city of Gateway, before heading to Grand Junction the next morning. There's nothing like spending five hours strapped into a seat, traversing hill and mountain, to truly test a vehicle's comfort and driving dynamics. From the first touch of the SQ5's push-button starter, we knew this was no ordinary Q5. As the engine came to life with a deep burble and raspy pops, and we spent the rest of the day trying to come to terms with the fact that not everything needs a diesel. Wait. What?!

The VW emissions carnage assessment with an upside

Bombs cause destruction. Even if they're intelligently guided and pinpoint, there's always collateral damage. The strange Volkswagen brew, which is still spontaneously combusting in plain sight, will result in aftershocks for years. And the professional end of the corporation's top leadership will not be the only casualties. Blows are striking shareholder confidence, the residual value of the cars involved, consumer confidence, and the German economy itself. A hard rain's going to fall elsewhere, too. Here are just four damage assessment areas. The High-Compression Past and Low-Compassion Future of Diesels Despite European and especially German manufacturers' high belief that diesel engines were a way to light-duty automotive salvation, VW's scandal started the last nail in the fuel's coffin. Regulations both in the U.S. and in Europe for particulates and nitrogen oxide (NOx) are getting much harder to meet, and this is at the very core of VW's deception. Even with the high-cost exhaust after-treatment systems, sky-high fuel pressure, and sophisticated electronics, the inescapable NOx realities won't be washable by technology in an affordable way. German engineering pride will have to work a real miracle to meet these looming regs and the stain of VW's scandal did the whole diesel movement no favors. Perhaps not so ironically, the E.U. adopted more stringent emission standards this year, which closely mimic the U.S. Tier 2, Bin 5 figures phased in for 2008. Indeed, when VW announced it was able to meet the stringent US NOx emissions standards in 2009 for its diesel engines without urea injection as an exhaust after-treatment, it was a particularly high point of engineering pride for the company. No other manufacturer had figured out how to do so. One Honda official at the time remarked that they had simply no idea how VW was achieving this feat and Honda couldn't come close. Well, neither could VW. On a macro scale, European cities are also starting to face government fines for air quality violations. This is forcing those cities to find various ways to cut smog-related causes like tailpipe emissions. In fact, Paris has gone to the length of restricting car use on a sliding scale when smog persists, while electric cars are free to roam. France's longer and larger plan is banning diesel fuel for light-duty transportation entirely. But why was there a frothy focus by the European manufacturers on diesels in the first place?
