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 Aventador SV gets more, less weight [w/video]

Following Lamborghini's recent tease, we were pretty certain that the Italian supercar brand would unveil its Aventador Superveloce at the 2015 Geneva Motor Show. Sure enough, during the Volkswagen Group Night event, the supercar with more power and less weight made its grand debut. Technically dubbed the Aventador 750-4 SV, Lambo revised the valve train and added a new four-exit exhaust with less backpressure. The result is a redline now at 8,500 rpm and a boost to 740 horsepower and 509 pound-feet of torque. Grunt still gets to all four wheels via a seven-speed gearbox. The changes help reduce the sprint to 62 miles per hour to just 2.8 seconds, and if that's not enough, 124 mph is just 8.6 seconds away from a standing start. The top speed reportedly rises to 217 mph. The other major factor in helping this improved performance is a 110-pounds reduction in weight to tip the scales at 3,362 pounds, which comes thanks to copious amounts of carbon fiber. On the outside, the door panels, side sills, fenders and new fixed rear wing are all made from the lightweight material, and the upgraded parts for the body reportedly increase downforce by 170 percent. The interior even features Lambo's Carbon Skin fabric for the headliner. Beyond the lighter weight and extra power, customers get magneto-rheological dampers, carbon-ceramic brakes and variable ratio electric power steering. All of this Italian performance comes at a price of 327,190 euros before any value-added tax when the cars go on sale in the spring. Official US pricing isn't announced yet , but that figure equates to about $366,000. Check out a video of the car being unveiled at VW's Group Night festivities in Geneva.

Details emerge on production-bound Lamborghini Sesto Elemento

The last we heard about the Lamborghini Sesto Elemento, Lamborghini had confirmed its production with only 20 examples of the track-only car planned, but now we're finally starting to get some of the details about this knife-edged car. AutoVisie recently had the chance to talk to Maurizio Reggiani, Director of R&D at Lamborghini, who not only confirmed what will power the new car, he also said that the production version will carryover almost untouched from what we saw in concept form at the 2010 Paris Motor Show.
What we now know is that the Sesto Elemento will share the same powertrain as the Gallardo LP570-4 Superleggera including the 570-horsepower V10 and the all-wheel-drive system, and it will be built at a new factory dedicated to building prototypes and limited-volume cars like this. Also, the report states a curb weight of 2,200 pounds, a top speed of 320 kilometers per hour (198 miles per hour) and a 0-100 kph (0-62) time of just 2.5 seconds. The only changes made to bring the concept to production were to increase the car's rigidity and its safety. This means the car will still feature all-carbon-fiber construction and unique bucket seats that are actually built into the car's body; driver adjustments coming from the steering wheel and pedals.
The estimated price for the Sesto Elemento is two million euros, or around $2.6 million US, and although the original production date was slated for early 2013, Motor Authority now says that we'll have to wait for another "year or two" to see this car in the wild. Also, it does not appear that this is the mystery car recently teased in a 50th anniversary video released by Lamborghini.
