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.

Audi traffic light recognition could save 240 million gallons of fuel [UPDATE]

Any hypermiler will tell you that the way you drive your car has a huge impact on how much energy it uses. But these greenfoot drivers haven't had a car that's smart enough to tell them about the inner lives of traffic lights. That's what a prototype system in an Audi A6 Saloon that the German automaker recently tested in Las Vegas can do. Since the car can communicate with local traffic signals and is able to predict when lights will change, the car can help reduce CO2 emissions by up to 15 percent. Further, Audi says that the system could save some 238 million gallons of fuel (900 million liters), if deployed across Germany. We can only imagine what hypermilers could do with this. We got to drive the Audi Online traffic light information system prototype in January, but we focused more on how the system worked rather than the green aspect. Now that Audi has had a bit more time to crunch the numbers, it has released fuel economy information for the connected car. The key points for the eco-side of things are that the driver is told in the dashboard how fast/slow to go to hit the next green light. This can help prevent unnecessary speeding and or encourage drivers to go a bit faster in order to hit the green, thus preventing idling and wasted time. The system is too smart to let you idle for long. Except that Audi Online is too smart to let you idle for long. The Audi connect system can calculate how much longer the light will be red and can access the car's start-stop capabilities and will fire up the engine "five seconds before the green phase." That seems like an awful long time in a world where competitors have figured out ways to restart an engine in 0.35 seconds. We've asked Audi for an explanation on why this buffer is so lengthy, and will let you know what the reasoning is when we hear back. Despite the trials in the A6, Audi says the Audi Online traffic system could be integrated into any Audi model, "subject to the necessary government legislation." Aside from the Sin City tests, Audi is running trials of the connected car in Verona, Italy and Berlin, Germany. If you'd like to test it out yourself some day, take heart from this line in the press release, available below: "A market launch is currently the subject of intense analysis in the United States." *UPDATE: Audi's Mark Dahncke told AutoblogGreen that the five second window is meant, "To alert the driver that the light is about to turn green.

VW execs didn't think diesel problem would be so serious

Volkswagen Group has admitted that former chairman Martin Winterkorn received two memos about the diesel scandal in 2014. Top execs ignored the problem because they didn't think it was a serious issue. VW disclosed these details to counter allegations in a German shareholder lawsuit that alleged the automaker violated the law by withholding the info from investors. A memo on May 23, 2014 first advised Winterkorn about emissions cheating. A memo on May 23, 2014, first advised Winterkorn about the study from the International Council on Clean Transportation, which identified the emissions cheating. According to VW, the document was part of the exec's weekend mail, and the company's investigation didn't discover whether Winterkorn actually read it. A rumor last month alleged this memo existed. Another memo for Winterkorn on November 14, 2014 was about several defects, including the diesel engines. The document estimated it would cost 20 million euros ($22 million US at current rates) to fix the problem. The chairman learned about the issue again on July 27, 2015, during a meeting on product issues. "Mr. Winterkorn asked for further clarification of the issue," according to VW's statement. Things got serious at the end of August 2015. Things got serious at the end of August 2015 when technicians explained the diesel issue to the legal department. VW came clean to the California Air Resources Board and the Environmental Protection Agency on September 3. A memo told Winterkorn the next day, which was also previously alleged. According to this investigation, management didn't believe the diesel problem would affect the stock price, and they estimated the cheating might cost at most a few hundred million dollars in fines. The execs were clearly wrong. The share price dropped after the scandal broke last September, and the problems have started to affect its divisions. According to Reuters, Audi reported it suffered 228 million euros ($249 million) in costs in 2015 from the emissions issue and repairing Takata's faulty airbag inflators. Volkswagen still doesn't know the exact costs of the scandal, but the automaker's law firm, Jones Day, plans to release a report in the second half of April to explain the whole affair. By that time, we might also know how VW plans to fix the problem because a judge recently gave the company until March 24 to outline a fix for the 2.0-liter TDI. CARB started evaluating a repair plan for the 3.0-liter TDI in early February.
