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.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

2015 Audi A8 and S8 get some new goodies

Luxury car buyers are a demanding bunch. They've got this crazy notion that just because they're spending the better part of a hundred grand on a top-tier luxury sedan, they should get the very best and the cutting edge of what the industry has to offer. That has tended to come down to the S-Class even when it had grown long in the tooth, and now that Mercedes-Benz has rolled out an all-new version, the competition is falling all over itself to release updates to keep their flagship sedans in the running. Jaguar did that just yesterday with its XJ sedan, and now Audi has revealed the latest revisions to its A8 range.
Set to debut at the Frankfurt show in just a few weeks from now, the latest A8 (and its performance version, the S8) benefits from a series of stylistic, powertrain, and technology upgrades. Among the most prominent, of all things, are the new Matrix LED headlights that can automatically lower the high-beams for oncoming vehicles, with integrated turn signals that light up to point in the direction the driver's about to turn. But that's hardly the end of the story.
Audi has apparently reduced the output on the 3.0-liter supercharged V6 to from 328 horsepower to 310 but raised the 4.0-liter twin-turbo V8 from 414 hp to 435, which now offers a 0-60 run of just 4.5 seconds. That's just three tenths behind the S8, which remains unchanged at 513 hp, as does the 493-hp 6.3-liter W12. The 3.0-liter TDI is up from 247 hp to 258, the 4.2-liter TDI grows from 345 hp to at 385 (with a massive 627 pound-feet of torque to boot) and the hybrid that offers a combined 245 hp and 354 lb-ft. That makes for one massive array of engines globally, although only some of them will be offered Stateside. Each is mated to an eight-speed automatic transmission and Quattro all-wheel drive, but thanks to the A8's lightweight construction, it's lighter than any other all-wheel-drive model in its class.
