Audi has revealed the details on the newest engine in the company's portfolio. The 1.8-liter, direct-injection, turbocharged gasoline four-cylinder produces an impressive 170 horsepower and 236 pound-feet of torque while returning 41.27 mpg in the A5 on the U.S. scale. That's a reduction in fuel consumption of as much as 21 percent compared to the outgoing engine, thanks in part to the clever use of both direct and indirect injection. In part-load range, fuel is injected into the intake runners

If you're a sports car aficionado, you already know what Nürburgring is: one of the world's most famous race tracks that is used both by car fans and auto journalists to test cars while going a little faster than authorities allow on normal streets. Audi, though, is proud of a recent event at the 'ring that had more to do with reducing fuel use than simple speed. Two Audi TTs with 2.0 TFSI engines mated to 6-speed manual gearboxes entered an efficiency contest, with the winner using 1.6 lit

Automakers claim that the new generation of small turbocharged engines keep the same performance or even improve older powertrains, as we saw for a VW Passat. However, it's good to know that a mostly performance-oriented publication, Auto News, has tested the new 122 hp 1.4-liter turbocharged VW engine, mated to a 7-speed DSG transmission. Their veredict? Yes, it works as advertised. The magazine's measurements verified the automaker's claims and found the Octavia a pleasure to drive although th

Volkswagen is introducing a new 160hp version of its 1.4-liter TFSI engine. This engine and the 122hp version are replacing VW's 1.6 FSI and 2.0 FSI engines which produced 115 and 150hp, respectively. This change in the engine lineup will start in the Golf Plus, Jetta and Golf Variant versions.

There have been countless conflicting reports about what will power the next generation Audi RS4 and the forthcoming RS5. Fourtitude had heard the rumors and decided to go straight to its sources for clarification. While the four-ringed obessesives weren't able to divulge the identity of their insiders (neither did CAR, which published of one the first stories about future RS powertrains), Fourtitude may have put to rest the rumblings that the next RS4 would ditch it's V8 in favor of a superchar

A 1.4-liter engine in such a large sedan? The downsized yet powerful 1.4 TFSI engine can now be ordered for the Volkswagen Passat with the new 7-speed DSG dual-clutch gearchange (a combination announced in the Seat Bocanegra concept recently as well). With these options, the car manages to get around with 6.4 l/100 km (6.5 in the station wagon version, which comes to about 37 mpg U.S.) and yet still reaches 200 km/h (115 mph). This Passat can also be ordered with the DCC adaptative chassis for a

Volkswagen has been one of the leaders in recent years in the area of downsizing engines. The German company was one of the first to start employing boosted and direct injected small displacement four cylinder engines to replace larger displacement equivalents. Yes, I know turbocharged engines have been used by the likes of Saab and others for years. I'm speaking specifically of the latest DI versions that are able to run higher boost and compression without pre-ignition. The same technology is

Just after introducing the TDI diesel version of their TT sports car, Audi also added a new, more fuel efficient gasoline version. The TT is now available with a 1.8L TFSI four cylinder. The new engine is turbocharged and direct injected to the tune of 160hp and 184.39 lb-ft of torque. The engine also features a variety of measures to reduce parasitic losses like a demand based oil pump that only delivers as much oil pressure as is actually needed. In the front wheel drive coupe, the 1.8L delive

Audi is launching a new TFSI engine in the A8 benemoth sedan car to compete with the other "eco" (let's just say less polluting) boats such as the Lexus LS 600h or even the BMW 7 Hydrogen (ahem). For only 61,000 EUR (around 80,000 USD) you can buy one of these in Germany.

It's well known by now that the enormous growth in the car population in China over the past decade and a half has put serious environmental pressure on cities there and dramatically increased gasoline consumption. Volkswagen was one of the first western car-makers to get involved in building cars there through their joint-venture with First Auto Works. Now VW wants to help clean up the air and reduce gas consumption. Volkswagen has already invested €80 million toward a total of €145 m

Audi has developed a new 1.8-liter turbo FSI direct inject engine to become the new base engine for its A3 compact in Europe. The new motor is likely a downsized version of the brand's 2.0 TFSI engine and produces around 160 horsepower and 185 ft-lbs. of torque. It will be able to propel the A3 to 62 mph in 8.2 seconds.
