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:

Actor Eric Bana returning to Bathurst 12 enduro race

Eric Bana joins the field of the 2014 Liqui-Moly Bathurst 12-Hour race next month, driving for the Australian FXD Workwear team. Bana's done the race twice before, coming in tenth overall in 2009 in his Love the Beast Mitsubishi Lancer RS Evo X, posting a DNF in the same car in 2010.
This year he'll be in Class B behind the wheel of a Lamborghini Gallardo GT3 prepared by Racing Incident, joined by teammates Peter Hill and Simon Middleton. The race happens during the weekend of February 7-9, you can find a press release with the announcement below. You'll want to take the time to get to know it this year, because it's been widely reported that Eric Bana will return next year to share a Porsche 911 GT3 with Mark Webber.

Lamborghini Aventador SV Roadster gets chilly shakedown

It was only days ago that Lamborghini gave the Aventador Superveloce its official debut at the Geneva Motor Show, but apparently the Italian brand has been hard at work on the next variant too. For those that want a 740-horsepower, 6.5-liter V12 singing a sweet song just behind their ears with the top down, then Lambo is testing an SV Roadster in the arctic. While the model is wearing copious camouflage and some very cool spotlights, the removable roof panel is still fairly obvious in several of these spy photos. Beyond the top, it doesn't look like Lambo is doing much to the body design, though. All of the pieces here can also be found on the SV coupe. There's no word when the SV Roadster might debut. Although with the standard model already complete, development of the convertible probably shouldn't take too long. The official unveiling might even be before the end of the year, especially with the coupe beginning sales in Europe in the spring.
