Audi details updated 3.0L V6 TDI engine

The brands in the Volkswagen Group have shown that they can develop some of the world's best diesel engines for passenger cars. At the Vienna Motor Symposium taking place May 8 and 9, Audi has an updated one to add to its lineup. It's launching a new version of the 3.0 TDI V6 with better efficiency and more power than the version currently in the US.
The new diesel will be offered in two tunes: 215 horsepower or 268 hp. However, Audi isn't giving away all of the new engine's secrets just yet. It says "depending on model" the mill makes as much as 442.5 pound-feet of torque and gets as much as 13 percent better fuel economy. That likely means the more powerful version gets the twist, and the other one has the better consumption, but we'll have to see.
To compare, the current 3.0 TDI offered in the US produces 240 hp and 428 lb-ft of torque. In the A6, it's rated at 24 miles per gallon city, 38 mpg highway and 29 mpg combined, according to the EPA.

Refreshed A1 packs Audi's first three-cylinder gas engine [w/video]

Back in 2010, Audi debuted the diminutive A1, and it's sold over half a million of them since. Now, more than four years later, the German automaker has given its smallest and most accessible model a facelift and some updated equipment.
The latest version of the A1 benefits from a range of updates, including a sharpened take on the company's familiar styling with a reshaped single-frame grille, new bumpers front and rear as well as new wheel and color choices. But the biggest news is the introduction of Audi's first three-cylinder gasoline engine.
The turbocharged, direct-injected 1.0-liter three-pot churns out just 94 horsepower, but that's still six more than the previous base 1.2-liter four offered, all the while returning better fuel economy and emissions figures. Of course, that turbo three is not the only engine on offer, joining the 1.4-liter turbo four in 123- and 148-hp states of tune and the 113-hp 1.6-liter TDI. And of course there's still the 228-hp S1 performance model. Depending on specification, the engines are mated to a five- or six-speed manual, but can all be optioned with a seven-speed dual-clutch transmission as well.

Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.
