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 reveals S3 Cabriolet ahead of Geneva debut

It used to be if you wanted an Audi S3, your choices in bodystyle came down to hatchback or... hatchback. That is, in markets where the model was offered at all. But Audi has been expanding the A3 global family upon which the S3 is based, and it intends to offer the performance-minded derivative as a three-door hatch, five-door hatch, four-door sedan and - with the introduction of the version you see here - a two-door convertible.
Set to be presented in public for the first time at the Geneva Motor Show early next month, the new Audi S3 Cabriolet packs the same 2.0-liter turbo four as its fixed-roof counterparts - all 290 horsepower and 280 pound-feet of it - but ditches the extra doors and the tin top in favor of the two-door cabriolet bodystyle of the A3 Cabriolet.
The added weight of the folding fabric roof mechanism and the extra body reinforcement required means that the S3 cabrio takes half a second more to reach 62 miles per hour from a standstill than it would take the sedan version, clocking the run at 5.4 seconds instead of 4.9. This, despite more generous use of magnesium, aluminum and high-strength steel in its construction. Top speed, as is the German custom, remains pinned at 155 mph.

Audi 4.2-liter V8 to live again in next-gen R8

Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.
We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.
It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.
