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.

2014 Audi SQ5 Road Test

It may be obvious at this point, but here in the United States, European manufacturers routinely give us the short end of the stick. Now, I'm not talking about models or brands that don't come here, like the Mercedes-Benz A-Class or the entire Renault line. No, instead, I'm referring to cars that are sold right here in the Land of the Free in one bodystyle, while Europe enjoys the same vehicle with a wider variety of configurations. A prime example of this is the Audi S4/S5 line. In America, we can have the supercharged twins in two-door coupe, four-door sedan, and cabriolet body styles. Meanwhile, our Euroland cousins get the same trio of bodystyles, as well as the A5/S5 Sportback, a characterful 'four-door coupe,' and a versatile hauler, the S4 Avant. At first glance, Audi of America lacks a vehicle that can compete with the latter's blend of performance, versatility and subdued looks. So, what's an American with around $60,000 and an obsession with quick, conservative haulers to do? Well, he can buy an SQ5. (Though it bears mentioning, our US-spec SQ5 is vastly different than what's available to our European friends.) The SQ5 has a huge number of things going for it that make it a viable alternative to a proper hot wagon, and foremost among them are its looks – this is a sleeper. Audi has thankfully decided not to molest the clean looks of the standard Q5 when penning the sportier model. The SQ5 gains a unique set of wheels: 20-inchers are standard, but our tester was fitted with a set of 21-inch rollers. Visually, neither make a huge departure from the standard Q5 though. Other standard features of Audi's S models are also found on the SQ5, including a set of quad exhausts, silver mirror caps and mildly different front grille and foglight surrounds. If anything, the Q5 TDI diesel I tested late last year looks sportier than today's tester. Audi has decided not to molest the clean looks of the standard Q5 when penning the sportier model. It's a similar story of minor but purposeful changes in the cabin. Audi has ditched the Q5's standard steering wheel and slotted in the excellent, flat-bottomed unit found in other S models, which in this case is flanked by a set of high-quality "alu-optic" paddles. Upgraded leather seats complement the new wheel, while my SQ5 offered the Carbon Atlas interior trim (a $500 option).
