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 Huracan LP 610-4 Spyder opens up in Frankfurt

The Lamborghini Huracan is still a fairly fresh member to the supercar scene, but at the Frankfurt Motor Show, Lamborghini is giving its wealthy clientele an open-air variant of the V10 with the newly unveiled LP 610-4 Spyder. The introduction finally gives the brand a natural successor to the discontinued Gallardo Spyder. Mechanically, buyers are still getting a Huracan with its 5.2-liter V10 pumping out 602 horsepower (the 610 in the name is in metric ponies) and 413 pound-feet. A seven-speed dual-clutch gearbox routes power to all four wheels. Performance is quite brisk, with the sprint to 62 miles per hour coming in 3.4 seconds and to a top speed of 201 miles per hour. One thing the hardtop obviously can't match is the power-retracting roof that can open up in just 17 seconds at speeds up to 31 mph. Lambo's designers didn't just take a saw to the top and go sip an espresso, either. The roofline is thoroughly resculpted behind the seats both for improved aesthetics and to direct airflow around the occupants. When the roof is down, it's easier to spot the new nacelles that run down the rear of the supercar. Ducts in those bits help reduce turbulence, and they look great too. Another cool touch is that the rear glass is power operated and can be opened to let the V10's roar into the cabin. The first Huracan LP 610-4 Spyders arrive in spring 2016. Lamborghini is setting prices in Europe at 186,450 euros before taxes ($210,111 at current rates). The actual US figure could be somewhat different, though. Related Video:

The Huracan Performante is still a supercar steal, regardless of 'Ring time validity

When Lamborghini released video of its new Huracan Performante lapping the Nurburgring in a stunning 6:52, not everyone was convinced the record was honest. As a result, Lamborghini's director of research and development provided some data to Roadshow to shore up the lap time claim. He addressed the tire issue by telling Roadshow that the car used the optional Pirelli Trofeo Rs. And he noted that it was quicker than its more powerful brother, the Aventador SV, because it cornered and accelerated faster. He even provided VBox data of the lap. The thing is, none of this really matters in the end, particularly for the Huracan. Let us explain. For one thing, if you're going to question the Performante's time, you should question all of the times. All of these records are presented by the manufacturers, so there isn't a truly impartial party measuring the results and inspecting cars. Even with a company presenting plenty of data and explanations, it's hard to be 100 percent sure everything is on the level without an unbiased third party inspecting the cars before and after the lap, and keeping timing. But besides the issue of impartiality, the times themselves aren't really important. As interesting and fun as it is to compare lap times at the Nurburgring, they're really only relevant for rich owners and car companies to brag, and for less-rich fans to bench race. That's not a bad thing, but to look at the lap time of one single track doesn't really give a full picture of a car's performance. A car that's fast at the Nurburgring could be really slow on a tight course like Streets of Willow Springs. There's also the issue of who's driving the car. The manufacturers put their top drivers out on the 'Ring to set times. If you're not a factory test driver, you'll probably never go that fast even if you did get your car to the track. It's all a bit like the silly "blind" or two-wheeled car records. They don't actually provide much info on what the car is really like, or how you could drive it. Even if you're not on board with this explanation, and trust all the 'Ring records except this Lamborghini, we still have a reason why it doesn't matter. You see, even if you're convinced that there's no way the Huracan could best the Porsche 918 Spyder and the Aventador around the Nordschleife, it's still a screaming supercar bargain. The Porsche is a million-dollar car, and the Aventador, just the base model, is $125,000 more than the Huracan Performante.
