Audi considering turbo option for longer, wider Hurac?n-based R8

The debut of the Lamborghini Huracán was (and remains) big news in and of itself, but equally as exciting is the imminent arrival of the Audi R8, which the Huracán presages. While the two will share a common architecture, don't expect that new R8 will simply be a cheaper version of the Huracán (like the current one arguably is to the Gallardo).
For one, the next R8 will be larger than the Huracán. According to emerging intelligence, Audi will make its sports car both longer and wider than the Lamborghini version. It'll also share the new Lambo's innovative carbon-fiber structure that will replace both the firewall and central tunnel. But to power it all, Audi will get more creative.
The next R8 will, like the current model and like the Huracán, offer a V10 engine at the top of the range. It will also offer the same 4.2-liter V8 as the outgoing model. But that won't be the end of the matter. Word has it that Audi is also working on a smaller, turbocharged engine to offer in certain markets that mandate smaller-capacity engines.

2015 Audi S8

You've gotta hand it to the Audi A8. Last year, Mercedes-Benz launched the truly stunning S-Class, putting the rest of the high-dollar luxury flagship class on notice. With the brand-new S-Class turning heads and garnering all sorts of praise from the automotive press, classmates like the BMW 7 Series, Jaguar XJ and Audi A8 started to look, well, old. But Audi didn't see fit to just let its big sedan carry on and let the Mercedes take the cake.
So when Audi refreshed its A8 line for the 2015 model year with only minor updates, I kind of shrugged it off as just a quick way to keep the big sedan fresh until an all-new, hopefully S-Class-trumping version arrives. But then I drove the S8 pictured above, and I'm no longer so sure the Merc's shadow is as big and imposing as it once was.
Spoiler alert: the Audi S8 is simply fantastic.

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.
