Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.

Comparison test: 2019 Acura RDX vs. compact luxury SUV competitors

Truth be told, if we were to compare the all-new 2019 Acura RDX with those compact luxury crossover SUVs it would most likely be cross-shopped against, you'd be looking at a different list. Even Acura admits that Lexus and Infiniti are the most likely bogies, but with the 2019 RDX, Honda's luxury brand is attempting to attract those customers who think as much with their hearts as with their heads. And for the most part, those folks have been buying from German brands: the Audi Q5, BMW X3 and Mercedes-Benz GLC-Class. So, to show how the new RDX compares to them, Acura actually provided examples of each during the recent press drive along with a Volvo XC60. All were determined to have greater emotional appeal than the last RDX, and we would certainly agree. For, as much as the previous-generation RDX made sense on paper, it was really hard to get excited about it. And when you're paying extra for a luxury vehicle, shouldn't you get a little excited? Well, as luck would have it, Consumer Editor Jeremy Korzeniewski and I were on hand in Whistler, British Columbia, for the press launch. We didn't have an abundance of time in each RDX competitor, but in conjunction with our usual comparison chart, our impressions should provide a good first taste of how the new RDX compares. Performance and fuel economy Contributing Editor James Riswick: On paper at least, the RDX is gutsier than its comparably powered European rivals. It also weighs the same or less, which logically should mean it'll be the quickest in a straight line. During my brief drives, though, I'm not sure it really stood taller than the three Germans. It at least matches them for smoothness, which is something that can't be said about the Volvo. Fuel economy is lower than them all when you consider all but the Mercedes come standard with all-wheel drive. It's also worth noting that all the competitors are available with engine upgrades, and unless Acura's forthcoming resurrection of Type S models includes the RDX, it should stay that way. Consumer Editor Jeremy Korzeniewski: Line 'em all up in a drag race, and I have a feeling the Acura would squirt away to victory. A good bit of that, though, would be due to its 10-speed automatic transmission, which offers a huge spread of ratios and fires off extremely quick shifts. In the real world, I'd guess fuel economy will be similar across the board, so I'm willing to call that category a draw.

German prosecutors have recorded calls between VW bigwigs talking dieselgate

It's barely possible to believe how poorly Volkswagen continues to handle dieselgate. Depending on which day you catch the news, the German carmaker embodies the corporate venality of "Michael Clayton," the comic blundering of the Coen Brothers' "Burn After Reading," and the every-man-for-himself vengeance of "Reservoir Dogs." Today is Tarantino day, with news that German prosecutors have recordings of phone calls between former Audi and Porsche development boss Wolfgang Hatz, ex-Volkswagen Group executive Matthias Muller, and current Porsche executives Oliver Blume and Michael Steiner. Hatz made the calls to the trio in November 2015, two months after Volkswagen admitted its diesel-particulate sins to the U.S. Environmental Protection Agency. Hatz was still employed at the time, and in his company car. Who recorded the calls? His wife. Hatz and his missus apparently saw the storm coming and started stacking defenses early. Hatz's wife, who can be heard encouraging Hatz during at least one call, sent the recordings to Hatz's attorney from her mobile phone. According to a Google translation of the German newspaper Handelsblatt's report, she included the note, "Here is a very long, but quite informative conversation on the current situation with useful formulations." The report in Handelsblatt said that in Germany it is generally "not allowed" to record a conversation and pass it on to a third party. We don't know how the authorities will handle this matter, since prosecutors found the recordings in e-mail attachments on Mrs. Hatz's mobile phone. Remember, when the diesel scandal broke, VW spent months saying that only a small number of low-level personnel were behind it, and all of the higher-ups had been blindsided. Ex-CEO Martin Winterkorn claimed to be "stunned that misconduct on such a scale was possible in the Volkswagen Group." Winterkorn successor Matthias Muller said, "according to current information, a few developers interfered in the engine management." Former VW USA honcho Michael Horn told a congressional committee that "a couple of software engineers" programmed the software for reasons no one could understand. In the recorded conversations, Hatz apparently called Muller to find out how VW planned to treat him.
