2017 Audi S4 First Drive

For all its power and easy performance, the best thing about the last Audi S4 was its uncanny ability to act like a normal (but very high-spec) A4 for most of its life. Then, when you needed or wanted a bit more speed or a bit more grip, you pushed a button or opened the tap and it became something else. It became a thing with more grip, more poise, more focus, and more gristle, but the changeover between the two S4 characters was seamless. That doesn't seem to be the case with the new one. The latest, B9 A4 has been well received and is probably the best mid-sized premium car out there, so that should have left the S4 a simple job to become the best warmed-up premium mid-sizer. It hasn't quite happened like that. The spec sheet suggests the S4 should come out on top in the fight with the BMW 340i and the Mercedes-AMG C43, but the numbers aren't everything. The engine seems impressive on paper; the all-new EA838 3.0-liter turbocharged V6 was jointly developed with Porsche (and it's closely related to Porsche's next V8, with which it will share non-internal bits like the camshaft chain). The 60-degree V6 weighs 31 pounds less than the old S4's supercharged V6, and it's replete with variable valve timing and lift, centrally mounted fuel injectors, and both direct and indirect fuel injection. That gives it 354 horsepower at 5400-6400 rpm (up 6.5 percent) and 369 pound-feet of torque from 1,370 to 4,500 rpm. That gives it a peak 44 lb-ft higher than the old one, spread across a band 600 revs broader. At 2,000 rpm, where drivers live every traffic light, it has another 74 pound-feet. That's enough motivation to move to 62 mph in 4.7 seconds. There's a new all-wheel-drive system that usually shoots 60 percent of the torque to the back but can ramp that up to 85 percent when it needs to, or it can swing it around to fire more than 70 percent to the front axle. The category benchmarks suggest turbocharged 3.0-liter gasoline sixes are the thing to have, with the Mercedes-AMG C43 using one, the 340i BMW having one (though it's straight), and Maserati's Ghibli also using one. The oddball is Jaguar's XE S, which uses a supercharger. You know, like Audi just ditched. The S4 trumps all but the C43 on power (the nine-speed Benz has 362 hp). While it ties the Ghibli for torque, it again trails the Benz (by 15 lb-ft) though its torque peak hits far earlier (the Benz waits until 2,000 rpm).

Volkswagen finds CO2 'irregularities' for 800k vehicles

The latest issue for Volkswagen affects another 800,000 vehicles, and this time its for irregularities in CO2 emissions certifications. VW estimates this issue could cost the company $2.2 billion to fix. The company officially makes no specific mention of which engines are covered, the models they are in, or even where they are located. VW discovered the situation during its ongoing internal investigation, and, according to the automaker, "it was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process." Most of the affected vehicles are diesels, and the company is now reaching out to "the responsible type approval agencies" to figure out the next step. While VW isn't officially confirming which models and engines are involved, Automotive News reports that it affects some 2012 and later VW, Audi, Seat, and Skoda models with the company's 1.4-, 1.6-, and 2.0-liter diesel engines, as well as the 1.4-liter ACT gasoline engine. The issue mainly affects vehicles sold in Europe. "The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency," CEO Matthias Muller said in the announcement. Volkswagen Group of America spokesperson Jeannine Ginivan was able to provide some further clarification to Autoblog. "This is not related to US-certified vehicles," she said. Clarification moving forward: internal investigations at Volkswagen identify irregularities in CO2 levels Matthias Muller: "Relentless and comprehensive clarification is our only alternative." Around 800,000 Group vehicles could be affected Initial estimate puts economic risks at approximately 2 billion euros The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels. Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected. An initial estimate puts the economic risks at approximately two billion euros. The Board of Management of Volkswagen AG will immediately start a dialog with the responsible type approval agencies regarding the consequences of these findings. This should lead to a reliable assessment of the legal, and the subsequent economic consequences of this not yet fully explained issue.

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.
