Audi Prologue concept drives itself to CES with updated powertrain

What's the point in crafting a one-off concept car if it only gets to stand in the spotlight at one show? That's what automakers have been asking themselves recently, and the answer has, generally speaking, been to repaint their show cars, give them a bit of new tech and put them back on center stage. And the latest to do so is Audi, which has given its Prologue concept a new lease on life. The Prologue was originally unveiled at the Los Angeles Auto Show less than two months ago, showing the way forward for the future of Audi design, in an elegant coupe form that looked ready to take on the Mercedes S-Class Coupe. We even got a chance to drive it around the streets of LA, and when we did, we marveled at the concept's advanced infotainment system that caters a range of personal preferences according to who's on board. "It's easy to see how this could even reach for chauffeured, or autonomously driven vehicles" in the future, we said at the time. And it turns out Audi was on the same page. At CES this year, Audi has brought back the Prologue concept, given it a darker coat of grey paint, a grey-tone interior (instead of the previous shades of brown and tan), a fresh set of wheels and equipped it with the autonomous tech the German automaker has been at the forefront of developing. Though other automakers have been fitting their self-driving prototypes with all-electric powertrains, Audi kept the 4.0-liter twin-turbo V8 in place – but fitted it with a hybrid assist to drive output up from an already prodigious 605 horsepower and 516 pound-feet of torque to an even more impressive 677 hp and 701 lb-ft, dropping the 0-62 time down to 3.5 seconds. Now that's the kind of "piloted driving" tech (as Audi calls it) that we can get behind.

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.

Audi reveals 'rightsized' 2.0 TFSI engine for next A4

Downsizing engines is a trend sweeping the industry. It's not a new thing, and downsizing helps automakers cut fuel consumption and emissions while employing techniques like turbocharging and direct injection. Audi, however, is taking a different approach with its latest engine. Revealed at the Vienna Motor Symposium in Austria is Audi's newest trick powertrain. Where others are going with smaller engines, Ingolstadt's latest displaces a nice round 2.0 liters, employing a shorter intake time to use less fuel. It's sort of like the Miller cycle that Mazda brought to market on the old Millenia, only turbocharged (instead of supercharged) and brought up to date. Audi calls the four-pot "rightsized," producing 190 horsepower and 236 pound-feet of torque across a broad rev range, while getting 47 miles to the gallon – and that's on the US cycle, which is tougher than the European standard a company like Audi would usually quote. In short, it's designed to provide power where needed but only sip at the fuel tank when it's not, but the geekiest among us will want to delve into all the intricacies outlined in the announcement below. The engine is set to power the next-generation A4 before being rolled out in additional models in the future. Ingolstadt/Vienna, 2015-05-07 World premiere at the Vienna Motor Symposium: new high-efficiency engine from Audi - New 2.0 TFSI four-cylinder engine with innovative combustion method - Top figures: 190 hp, 320 Nm (236.0 lb-ft), less than 5 l/100 km (47.0 US mpg) - To be implemented in the new Audi A4 by the end of 2015 - Prof. Dr. Ulrich Hackenberg: "A prime example of the Audi rightsizing strategy" Audi presents the most efficient two-liter gasoline engine in its class. The new 2.0 TFSI with 140 kW (190 hp) demonstrates the engine expertise of the brand – with a ground-breaking new combustion method. Audi will be using the engine for the first time in the next generation of the A4. Over ten years ago, Audi was the first manufacturer worldwide to bring the TFSI engine with turbocharging and direct injection into series production. This made the brand with the four rings the trendsetter in downsizing and downspeeding. "We're now taking a crucial step further with rightsizing," said Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at AUDI AG.
