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 sets diesel records on road and track

Ever the proponent of diesel propulsion, Audi has claimed two very different kinds of records in Europe with its finest oil-burners. The more exciting of the two was achieved recently at the Sachsenring, where the Audi RS5 TDI Competition Concept posted the fastest diesel-powered lap time ever recorded on the track. As you may recall, Audi revealed the RS5 TDI Concept last year, swapping the gasoline-burning 4.2-liter V8 in the production RS5 coupe for a 3.0-liter V6 diesel with two turbochargers and an electric supercharger. The result was 385 horsepower and 553 pound-feet of torque, but Audi's been working on the prototype over the course of the past year. In the new Competition version, output is up to 435 hp and 590 lb-ft, and despite the inherently heavier diesel engine, it actually weighs 531 pounds less than the production model. That helped the RS5 TDI Competition lap the circuit in 1:35.35, besting the previous diesel lap record by 1.87 seconds, and adding to the Hockenheim record it took previously. Around the same time, another team set out from Maastricht in the Netherlands in an Audi A6 TDI Ultra and drove it for 28 hours straight, hitting 14 countries and logging 1,158.9 miles on a single tank of diesel. The achievement, certified by Guinness World Records, was completed in a showroom-stock vehicle, with automotive journalist Andrew Frankel and racing driver Rebecca Jackson splitting driving duties. They achieved an average of 75.9 miles per gallon – much better than the advertised rating of 67 mpg – as they cruised through from Holland to Hungary, passing along the way through Belgium, Luxembourg, France, Switzerland, Lichtenstein, Austria, Germany, Italy, Slovenia, Croatia, Bosnia, and Serbia. Record: Audi RS 5 TDI competition concept drives to record time on the Sachsenring track - Audi sets new lap record for cars with diesel engines - Superior technology platform with 435 hp and 800 Nm (590.0 lb-ft) - Electric compressor: overcomes turbo lag, enhances sprint performance Audi has set a new record time on the Sachsenring for cars with a diesel engine. The Audi RS 5 TDI competition concept rounded the 3.6 km (2.2 mi) race course in a time of 1 minute 35.35 seconds. The technology platform draws its power from a 3.0-liter V6 biturbo TDI with 320 kW (435 hp) of power and 800 Nm (590.0 lb-ft) of torque. The highlight is an electrically driven compressor.

Audi shows off the Prologue Avant Concept as a plug-in hybrid

The Audi Prologue Avant Concept goes in a different direction than the Prologue coupe, in more ways than just its five-door wagon body. The coupe was first shown at the LA Auto Show with a 4.0-liter, twin-turbo V8, then went redux at CES as a hybrid with a total of 677 horsepower and 701 pound-feet of torque. The only-slightly-larger Prologue Avant sticks with the hybrid but gets the system from the Q7 E-Tron quattro, meaning a 3.0-liter, twin-turbo V6 TDI with 353 hp and a 100-kW electric motor strapped to the eight-speed transmission. Total output is 455 hp and 553 lb-ft, pure electric range is 33 miles, and 0-62 miles per hour comes in 5.1 seconds. The forward section of cabin with its screen-based Tie Fighter displays and controls comes over from the coupe, as well as the four individual seats, but the Avant lavishes attention on rear passengers in ways not possible in the two-door. They also get a screen on the pass-through center console for convenience controls, and detachable OLED screens - a la the detachable tablets in the Q7 - with which they can send information to the front occupants. As a traditional Audi avant is to a coupe relative, the Prologue Avant is all about bringing the family along on the digital highway. We'll see it at the Geneva Motor Show next week, and Audi is again talking up how the design language will migrate to production cars. It also makes noises in the press release below about near-production many of the technologies are in the concept, so it looks like there could be all sorts of Easter Eggs on the way from the Ingolstadt brand.
