Creative minds build lightweight Lambos and Bugattis with cardboard and pedals

As manufacturers continue their quests to reduce the weight of their vehicles, they switch out heavy steel for lighter materials such as aluminum, carbon fiber, titanium, and sometimes even magnesium. But they've been ignoring a cheap alternative that is widely available: cardboard. Leave it to two visionaries from Vietnam to crack the code and build supercars and superbikes out of the versatile paper product. Vietnamese YouTube channel NHET TV, via CarScoops, might only have a year under its belt, but in that short amount of time, it has amassed more than 350,000 subscribers. What initially started out as a random collection of harmless pranks, trolls, and makeshift time-killers has blossomed into an entertaining channel of ultra-low-budget car and motorcycle builds.  The first video posted is a paper plane competition, but the second video shows the first appearance of a vehicle, a Ducati Panigale made out of cardboard and a bicycle. This isn't like Paper Mario with a two-dimensional silhouette, it's a close-enough three-dimensional replica. That project was admittedly pretty rough, but the work has only improved as the channel has matured.  Throughout the past year, NHET TV has stuck with high-performance transportation for inspiration. They've built projects that mimic a Lamborghini Sian, a Lamborghini Aventador SVJ, a Ferrari LaFerrari FXX K, a Bugatti Chiron, a BMW S 1000 RR, and a Yamaha YZF-R6, among others. Some of the builds, such as the Bugatti, go beyond the typical cardboard-body-on-bicycle-frame. As seen in the video below, the NHET TV built a tubular frame for the car using spare bike parts that they welded together. The Bug even has a custom steering column and steering wheel, though the high-quality model continues to use bike chains and pedals for power. The SVJ might be the most advanced vehicle, as it has a real engine for power and has custom reverse gearing. These guys are creating fun out of the limited resources they do have, and that's what right now is all about. Enjoy the videos below and watch more on the full NHET TV channel.

The 2016 BMW M2 is a steroid-addled M235i [UPDATE]

UPDATE: As it turns out, BMW mixed up the weight specs in the official press materials. We spoke to BMW for confirmation, and the manual M2 weighs 3,450 pounds, the DCT car weighs 3,505. We've updated the text to reflect this. If you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. When we first got behind the wheel of the M235i early last year, BMW was quick to point out the spiritual link between the small quasi-M car and its ancestors, the 2002 Turbo and the E30 M3, but we couldn't help but think fondly of the more potent 1M Coupe. And while the M235i got a lot of things right, its weight and price took some of the shine off it. But more importantly, the intangibles that those older BMWs nailed was somewhat lacking in the M235i – while fun, it was somewhat distant, unlike the visceral 1M. Until we drive the 2016 BMW M2, those intangibles will remain intangible. But on paper, the M2 looks to be a super-M235i, buffed up with M goodies like an active rear differential and lightened suspension components. But if you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. With the manual it weighs 3,450 pounds, an 85-pound reduction. With the DCT, it's a wash at 3,505 pounds. At least the M2 looks like a proper M car. The side bodywork swells 2.1 inches up front and 3.1 inches in the rear to accommodate wide 19-inch forged wheels wrapped in Michelin Pilot Super Sport tires. The front end takes the M235i theme (itself an adrenaline-injected version of lesser 2 Series cars) and adds steroidal menace, with the expected larger intakes to feed the extra engine radiator. Out back, there's a diffuser in the rear tray that the M235i lacks, and the scallops that incorporate the taillights plainly telegraph the extra rear width. It's the M4's handsome younger sibling. Like the M235i to which its clearly related, the heart of the M2 is a 3.0-liter inline-six that inhales through a TwinScroll exhaust manifold-integrated turbocharger. High-precision direct injection, Double-VANOS, and Valvetronic are all present and accounted for, with some M goodies like pistons and crank bearings trickling down from the M3 and M4. The result is 365 horsepower at 6,500 rpm and 343 pound-feet of torque available from as low as 1,400 rpm.

What does the open patents deal mean for Tesla ... and BMW?

Gift to the world or trade bait? Tesla Motors announced this week it would open its patents for other automakers to use. That has analysts guessing whether the California-based electric-vehicle maker is looking to either swap trade secrets with other automakers or to expand the proverbial pie that represents the plug-in vehicle market. For its part, Tesla says the answer is B. BMW, which is establishing its i sub-brand of plug-in vehicles, would be a natural collaborator with Tesla, Forbes says. In fact, executives from the two companies met in Europe this week. Details were not released, but a BMW spokesman said, "Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level." While Tesla brings battery technology to the table, BMW offers its carbon-fiber advancements that lighten vehicle-body weight. Those advancements are key to range-extending efforts and could do wonders for Tesla on its journey to help spur technology for the sake of getting more of the general public to accept plug-in technology as a viable first-car option. Then again, Forbes says Tesla, whose investors include Mercedes-Benz parent Daimler and Toyota, may be keeping its best technologies to itself by not patenting certain advancements at all. What's in Tesla's patent pool? uAutoInsurance analyzed Tesla's 249 patents and found that 104 of them related to battery technology, while 28 pertained to recharging activity, which wasn't surprising (about a quarter of those 249 patents couldn't readily be categorized). Tesla also has nine patents related to sunroof technology. The company is based in California, after all.
