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:

Dad 3D-printed a Lamborghini because his son liked one in Forza

Sterling Backus's son only had one question after he drove a Lamborghini Aventador in the XBOX video game Forza: Can we build one? Most dads would respond with a chuckle and some quip about winning the lottery. But not Backus, whose day job is laser physicist. Backus responded, "Sure," and he meant it. As of this week, the replica is capable of driving under its own power. Backus, the chief scientific officer at KMLabs in Boulder, Colorado, and his 11-year-old son dubbed the project "Interceptor," and the build has a budget of about $20,000. Backus hand-built the steel chassis and pulled an LS1 V8 from a Corvette for power. He found the panel layouts through online design community GrabCAD, and then he modified them for 3D printing.  But he ran into a problem: The 3D-printed plastic would melt in the sun. So, he decided to incorporate carbon-fiber encapsulation (shown below), in which he wraps the parts and covers them in epoxy. Piece by piece, he assembled the shape of the supercar using a Creality CR-10 105 desktop 3D printer that he got for about $900 from Amazon. The front brake air intake alone is said to have taken 52 hours to complete. Additional cool features include a gated shifter, functioning lights, and scissor doors.  One of the fun aspects of the whole story is that Backus admits he had some learning to do when it came to the art form of additive engineering. So, he turned to the same place everybody else goes these days: YouTube. The physicist joked that he went to YouTube University and learned by watching videos.  With the end of the project in sight, Backus says he wants the final product to serve as an educational tool for Science Technology, Engineering, Art, and Mathematics (STEAM) programs.  "The intent is to take the car to local schools to show kids how cool technology can be," the project's Facebook page says.  In the words of Jesse Pinkman, "YEAH SCIENCE!"  This content is hosted by a third party.

Lamborghini braces us for the end of Gallardo production

A changing of the guard is afoot in the Lamborghini stables. The Italian supercar brand sticks with a particular model for a respectably long period of time, thus any model changeover is cause for attention. First came the gloriously badass Aventador succeeding the Murcielago, which signals that the Gallardo replacement is on the way next. Not one to let any occasion go without its due pomp and circumstance, Lambo released a video entitled "The Final Gallardo."
The clip features various footage from the life of the Gallardo, worked in with a manifesto of sorts regarding Lamborghini's purpose, and how that fits into the Italian way of life. Little is stated about the Gallardo itself, let alone the eventual replacement. Additionally, it is unclear if the video is to celebrate a special "Final Edition," or merely the last Gallardo to roll out of Sant'Agata Bolognese. Until we do see the Gallardo successor, feel free to watch Lamborghini reveling in the sound of its own awesomeness in the video below.
