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.

1971 Lamborghini Countach LP prototype 500 lives again

On March 11, 1971, Lamborghini unveiled the Countach LP 500 prototype at the Geneva Motor Show on the Carrozzeria Bertone stand. Lamborghini had also brought the reworked Miura P400 SV to the show, and believing it would be the star, had placed the Miura at its own stand and dispatched the Countach to the design house stand. Admittedly, Lamborghini had done the same thing in 1966 when the Miura debuted in Geneva. The Countach ruled the 1971 show and was soon on magazine covers around the world. The Italian house spent three years developing the prototype for production, putting the Countach LP 400 on sale in 1974. The prototype sacrificed its life during crash testing for the production model. Now the prototype is back, or the best facsimile thereof. Lamborghini says "an important collector" approached the firm in 2017 asking if they could recreate the yellow shock that started the 50-year craze for V12 engines and scissor doors. That customer might have got his idea from the 1971 Miura P400 SV prototype that Lamborghini restored in 2017 using archival documents. So the automaker's classics division, Polo Storico, went back to the archives for drawings, documents, meeting notes and pictures; interviewed people who were there at the time; and contacted suppliers like Pirelli for an updated version of the Cinturato CN12 and paint maker PPG for the Giallo Fly Yellow Speciale color.

It took 2,000 hours for the design house, Lamborghini Centro Stile, to reproduce the bodywork, all of it hand-beaten as it was in 1971. It took more than 25,000 hours to recreate the entire coupe with parts that were either original, restored, or fabricated from scratch ranging from the platform frame (instead of the tubular frame in the production car) to the partially electronic instrumentation. Lamborghini didn't mention the engine, though. The prototype contained a 5.0-liter V12; the production model downsized that for a more reliable 4.0-liter unit. We'll guess a collector committed enough to pay for 25,000 hours of Lamborghini work wouldn't compromise on the heart of the matter. Whatever's back there, it sounds righteous in the video.  The result is now on display in the concept class at the Concorso d'Eleganza Villa d'Este.

Lamborghini's Aventador replacement will receive a new V12 engine

Lamborghini is about to close one of the longest and most significant chapters in its history. It announced the Aventador Ultimae unveiled in July 2021 is the last non-electrified, V12-powered street-legal model it will build. The car's successor, whose name hasn't been revealed yet, will inaugurate a gasoline-electric hybrid powertrain built around a new V12 engine. Company boss Stephan Winkelmann filled us in on some of the details. Sending off the non-electrified, V12-powered supercar is a big deal for Lamborghini, so a lot of time and resources went into increasing the engine's output for the grand finale. It develops 770 horsepower at 8,500 rpm and 531 pound-feet of torque at 6,750 rpm, figures that eclipse both the Aventador S and the Aventador SVJ. Winkelmann told Autoblog that 770 horses was "the best possible power output we could get" out of the 6.5-liter engine. It's the end of the road for this V12, because the Aventador's replacement will receive a new engine. Winkelmann said it's too early to reveal specific details, like its displacement, but he stressed it's not something we've seen before. And the hybrid system is notably not related to the technology that powered the limited-edition Sian. "The technology is different, it's a completely new engine, a completely new drivetrain, a new battery, everything is completely new. There's nothing out of the Sian or out of the Aventador [in the next flagship]," he said. Some things won't change. Winkelmann cited carbon fiber construction, four-wheel-drive, active aerodynamic technology, and a four-wheel steering system as attributes from the Aventador that are worth keeping. And, adding a turbo (or two, or three, or four) to the new V12 was never considered — forced induction adds weight and puts unnecessary stress on an engine. Besides, the V12 has "horsepower en masse." Natural aspiration is here to stay. Regulatory hurdles are part of what's driving Lamborghini towards electrification, so the Ultimae truly is the last of its kind. However, the non-electrified V12 could live on in some few-off models built for track use, like the Essenza SCV12. "For homologated cars, it's a no. For the others, we will see. It's not planned so far, but there could be an opportunity," Winkelmann replied when asked if future V12-powered race cars could eschew a hybrid system. This is it, then. Lamborghini will build 600 units of the Aventador Ultimae, a number split 350-250 between coupes and roadsters.
