Audi R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:

Audi claims America unfairly pushes electrics over diesels, backed by survey

Audi, in case you haven't noticed, is quite committed to diesel technology. It champions oil burners in both the racing world and to consumers, offering American customers a total of five diesel-powered models, which is more than any brand in the US market save for its parent company, Volkswagen. In a bid to prove that diesels aren't some passing trend and are actually gaining momentum in the US, Audi commissioned Harris Interactive to conduct a poll of 1,600 American drivers, to see how they felt about diesel power. The resulting statistics are rather surprising.
57 percent of the 1,629 drivers surveyed think the government has unfairly favored hybrids and electrics over diesel power
65 percent of drivers support laws being passed to make diesel more accessible, while 66 percent support tax incentives for diesel-powered vehicles

Leaked design sketch may preview Audi TT Sportback Concept for Paris

With the debut of the new TT and TTS hardtops in Geneva earlier this year, as well as the more recent debut of the convertible model, Audi has ticked the same body style boxes as the first two generations of TT. Unlike those earlier examples, though, the German luxury manufacturer has provided a slow and steady parade of concepts showing off possible directions for the TT.
First, we had the Allroad Shooting Brake Concept from the 2014 Detroit Auto Show. Then, in April, we saw the Offroad Concept, whose biggest differentiation from the Detroit concept was its extra pair of doors, making it appear, at least superficially, quite similar to one of Audi's Sportback models. This clear evolution from shooting brake to neo-Sportback might not have meant much, had the image you see above not leaked.
This is, allegedly, the third member of the larger TT-based concept family, and - surprise, surprise - it has massaged the profile of the Offroad Concept into something that, to our eyes, appears far more grounded in reality. It looks like a natural fit into Audi's line of four-door-coupe models, which are more fleshed out in Europe, thanks to the presence of the A5/S5 Sportback. Slotting in a TT-based model could represent a coup for Audi, as such a small four-door with such obvious sports car roots would be mostly unchallenged.
