Next BMW 4 Series convertible may ditch folding hardtop

In 2007 the E93 BMW 3 Series convertible switched from a fabric roof to a folding hardtop, but reports out of Germany and BMW say that the next-generation 4 Series convertible will go back to a fabric roof. AutoBild disclosed that nugget last month, now BMW Blog says a BMW source told their sister German publication BimmerToday that it's official and "a decision has already been made." The official car of pro tennis clubs around the world, the droptop 4 Series isn't due in dealers until 2020 or 2021 so one would think there remains some leeway about the top. However, teams of designers are working on the new car right now, so it's entirely possible that a design course is fixed. From the time that the model made the switch, fabric roofs have got so good that there is barely, if any, penalty for using them. It's supposed the change is being made to save weight and free up space. The next 4 Series range is aiming for a lot more sportiness, so on top of its CLAR (cluster architecture) body, it's expected to get active steering, adjustable dampers and anti-roll bars, bigger brakes, and brake-based torque vectoring. Detail improvements like reduced-friction wheel bearings, and faster torque transfer for its all-wheel-drive system are on the long list of upgrades. So too are aluminum and carbon fiber wheels, which will likely be developments based on the carbon wheels BMW showed off last year. Driver assistance options will be legion, with remote-controlled parking, semi-autonomous driving up to 40 mph, and hands-free overtaking perhaps among them.

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.
