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:

Lamborghini say no to turbos in supercars, for now

Lamborghini is preparing to launch what will not only be its first crossover (discounting the LM002 that was a proper truck), but also looks to be its first turbocharged model as well. But will the upcoming new Urus open the door for more artificially boosted Lambos in the future? That was the question on our minds when Autoblog caught up with Stephan Winkelmann at the opening of the new Trigeneration Plant in Sant'Agata Bolognese. "Naturally aspirated engines are still the best engines which are on the market for super sports cars, in terms of acceleration, in terms of sound," said Lamborghini's chief executive during a roundtable discussion at the factory. "And unless there is [something] better, we are going to keep them." "Naturally aspirated engines are still the best. Unless there is something better, we are going to keep them." "We are constantly looking for alternatives. We are constantly seeing what we can do to make them better," said Winkelmann. "And there will maybe a day when we are introducing turbos, when the turbos are equalizing or being better than naturally aspirated engines." That moment just hasn't come yet, in Lamborghini's estimation. This in sharp contrast to rivals like Ferrari and McLaren (to say nothing of its sister company Porsche) which are wholeheartedly embracing turbocharged engines, as well as hybrid propulsion. Any engine, turbocharged or otherwise, used to propel the Urus would not be so easily slotted into one of its mid-engined supercars, either. "Usually an SUV engine has a different stroke, so usually those engines have to be adapted if you want" to use them in mid-engined supercars, said Winkelmann. "Then they're at the front so you have to turn them, and if this is going to make sense, I don't know. At this time there are no plans to do that, but in general, these engines are not suitable" for models like the Huracan or Aventador. "There would be a day when we think that turbo can be better than naturally aspirated. And that day, we will step into it."

Autoblog's exclusive Lamborghini Aventador SV Roadster photo shoot

Sometimes it just takes a few little tweaks to transform something from good to great, and that's definitely what Lamborghini's stylists manage to do with the Aventador LP750-4 SuperVeloce Roadster. While there's no question that the Aventador SV coupe is an amazing machine, slicking off the roof for the newest version is the perfect bit of tailoring to create something truly bonkers. Why are we talking about it again? Following the roadster's debut in Monterey, we arranged a date with the car and our photographer extraordinaire, Drew Phillips. The result is the absolutely magnificent gallery of photos you see above, that you're definitely going to want to view in high resolution. The engineers at Lamborghini HQ in Sant'Agata Bolognese, Italy, had a pretty easy job when the time came to the Aventador SV droptop because it carries over all the special parts from the coupe. Still, buyers have no reason to be disappointed with the 6.5-liter V12 making 740 horsepower (750 in metric ponies) and offering a screaming, 8,500 rpm redline. The seven-speed gearbox and all-wheel-drive system zaps the convertible to 60 miles per hour in less than three seconds and to a top speed of over 217 mph. Weight also falls by 110 pounds compared to the standard roadster to tip the scales at 3,472 pounds – some 110 pounds more than the SV coupe. It's the razor-sharp styling that really makes the SV Roadster a showstopper, through. The droptop still wears the coupe's carbon-fiber body panels but somehow makes them look even better. The key is removing the two top sections to create a small break in the roofline, and that little change is enough to accentuate the rear's curvy hips. The side-mounted intakes look big enough to carry extra passengers in a pinch. Removing the roof and reshaping the rear emphasizes the nacelles running behind the seats even more. These elements are somewhat visible on the SV coupe, but the engine cover largely hides them. Here, the angular shapes are brashly obvious and look directly inspired by an F-117 stealth jet. To make things even better for the driver, the rear window can be lowered to fully open the cabin to nature. The first deliveries to customers don't start until early next year, and the $530,075 starting price makes it about $37,000 more expensive than the SV coupe. Lamborghini likely doesn't have to worry about finding buyers for this beautiful machine, and production is limited to 500 units, 100 fewer than the hardtop.
