Audi recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

2017 Audi S5 First Drive

Let's start with the obvious elephant in the room: The new 2017 Audi S5 looks mostly like the model it replaces. Is that a bad thing? We headed to Portugal to test out the S5 on that country's serpentine back roads, and to see if there's something more substantive behind its evolved exterior. Only compared to the decidedly more evocative Mercedes-AMG C43 Coupe does the svelte S5 come across as a little frumpy. It takes parking the new S5 next to the old one to spot the details. A tweaked profile. A more pronounced belt line. A power-dome hood. Narrower A-pillars. The new S5 is different, but the same, in that grand Audi tradition. Underhood, the differences are again evolutionary. The original S5 featured a 4.2-liter, naturally aspirated V8. A few years back, that was replaced by a supercharged 3.0-liter V6, which in turn has been supplanted in the 2017 S5 by a turbocharged 3.0-liter V6. The turbo, a twin-scroll unit nestled between the cylinder banks, helps the direct-injection engine make a healthy 354 horsepower and 369 pound-feet of torque. That power, 21 hp and 44 lb-ft more than its predecessor, is channelled through Quattro all-wheel drive. The newly developed V6 mates exclusively to a conventional eight-speed automatic, which seems like a step backward. Last year's S5 offered either a six-speed manual or a seven-speed dual-clutch gearbox. We pressed Audi and got the answer we expected: Demand for the stick was nonexistent outside the United States (go America!) and the dual-clutch couldn't handle the 44 pound-foot increase in torque. Curiously, the A5 on which the S5 is based trades last year's eight-speed autobox for a seven-speed dual-clutch. It sounds like someone at Audi put the wrong transmission in each car, but in reality the S5's torquey engine is well-suited to the refined eight-speed. Kick the throttle, get into boost, and all four drive wheels scrabble for traction, especially on the wet pavement we encountered outside of Porto, Portugal. Punch the S5 to pass on a tight two-lane road and the sport exhaust roars with the kind of guttural growl we want to hear in a sporty coupe. It positively scoots. Though its Volkswagen MLB 2 platform is new, the S5 rides and handles like a more refined version of its predecessor. Considerably less road rumble penetrates the cabin, and the S5 strikes a pleasant balance between grand-touring plush and sports-car firm.

The Audi RS3 LMS looks hot and ready

Audi had several reveals this week at the Paris Motor Show, but nothing was more batty than the new RS3 LMS race car. Audi's latest hot homologation car starts with the all-new RS3 sedan, removes all of the unnecessary bits and adds all the racing-spec equipment you could want. The result is a full-prepped, relatively affordable factory race car. That relatively affordable part is very important. Audi Sport, the division behind the R8 LMS as well as the R and RS road cars, designed the RS3 LMS for the still-new TCR FIA-spec racing series. The cars will cost about $112,000 USD for the club sport version and $145,000 with the six-speed sequential transmission. Not bad for a fully FIA-friendly factory machine. The new TCR series races follow other FIA series like Formula 1 and WEC. <p>Your browser does not support iframes.</p> All that cash get's nets you a pretty badass looking car, especially in Audi's black and red paint scheme. As you can see in the photos, the RS3 LMS is far wider than the standard sedan, which is fairly compact by modern standards. The requisite giant rear wing is present, as is the big front splitter. The RS3 LMS ditches the new road car's dual exhaust for a cool looking single, center-exit pipe. Inside, it's all bare metal and plastic, ditching any semblance of road-going civility. Under the hood, the RS3 LMS loses the new 2.5-liter turbocharged inline-five and replaces it with Volkswagen's 2.0-liter turbocharged four. In this application, the engine pumps out a healthy 330 horsepower. Audi claims a 0 to 60 mph time of 4.5 seconds. Audi says customer deliveries will start in December, so look for the new car on track starting in 2017.
