Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

2016 Audi TT Second Drive [w/video]

The original Audi TT is a modern style icon. But having a one-time design hit isn't a recipe for longevity. In order to succeed, you have to bolster style with substance. Thankfully, that's exactly what Audi did with its third-generation TT. Now more than ever, the TT is a proper sports car, and it debuts with a host of new technology. The car still looks good, but it's no longer a one-off masterpiece. Instead, it takes many of the original TT's elements and incorporates new bits of modern detailing. The shape is all TT – the roofline, the wheel arches – even smaller details like the fuel filler cap and exhaust outlets moved closer to the center of the vehicle pay homage to the original car's design. But the new car's face is more angular, more robotic. Park the new R8 next to this TT and the family resemblance is clear. "It's fair to say that the new car hasn't been comprehensively reconceived; it's been comprehensively re-detailed," says associate editor Jonathon Ramsey, who first drove a Euro-spec TT back in September. It's a good move, a way to "keep the icon alive," according to Audi AG exterior designer Dany Garand. But the better news is that the rest of the car is more than just a comprehensively re-detailed machine. Launch a TT coupe from a stop and you'll hit 60 miles per hour in 5.3 seconds. The TT rides on the same modular MQB architecture as the Volkswagen Golf. The whole package is the same length as before, but the wheelbase is stretched by 1.5 inches. At 3,186 pounds, the TT is only 11 pounds heavier than its predecessor, but thanks to new body components, it's 25-percent stiffer than the second generation. We sampled the base TT on the roads of northwest Oregon – that means there's a 2.0-liter turbocharged inline-four good for 220 horsepower and 258 pound-feet of torque. It's the same output as a GTI with the Performance Package in a two-door coupe that's 155 pounds heavier. But stay with us – the magic of Quattro all-wheel drive seriously comes into play here. Launch a TT coupe from a stop and you'll hit 60 miles per hour in 5.3 seconds. Even the TT Roadster is a firecracker, able to do that same 0-60 run in 5.6 seconds. That 220-hp, front-wheel-drive GTI, by comparison, hits 60 in about six seconds flat. We didn't get to drive the TTS, but based on numbers alone, it ought to be a real honey. The S uses the more powerful version of the 2.0T engine from the Golf R, with 292 hp and 280 lb-ft of torque. Zero-60: 4.6 seconds.

Audi prepping a flex-fuel A3 for Latin America

Volkswagen's Audi division hasn't fared well from its parent company's diesel-emissions scandal, especially in the US and Europe. In South America, though, Audi is set to unveil its first vehicle of the flex-fuel variety, according to Nseavoice. Perhaps the German automaker can earn some good karma down in the Southern Hemisphere. The model is the 2016 Audi A3, which is made in Audi's Brazil factory. The engine is a 1.4-liter variety, and it will be able to run on either conventional gasoline or ethanol, or a blend of both. The decision makes sense because ethanol is plentiful in Brazil since the government has long pushed for it and there's plenty of sugar-cane feedstock to produce the stuff. Audi can use all of the positive news it can get, especially in the wake of VW's diesel-emissions scandal. As many as 11 million VW and Audi diesels may have been fitted with software that cheats emissions-testing systems. One result from the scandal's proverbial shrapnel is that the Audi A3 TDI diesel was stripped of its 2010 Green Car of the Year Award by Green Car Journal. The decision marks the first time in the award's history that a winner was stripped of the honor. VW has a long history offering flex-fuel vehicles in Brazil. In 2003, the German automaker was the first to debut a flex-fuel engine, and within two years, VW's Brazil factories were making 300,000 flex-fuel vehicles annually. Other companies have since jumped into Brazil's flex-fuel fray, including Nissan and Honda.
