Ferrari patents a fancy and fascinating electric turbocharger

While turbocharging has improved vastly over the years, and it has enabled cars to become both more powerful and more efficient, there's always room for improvement. Turbochargers scavenge exhaust gas pressure and use it to turn a compressor that forces intake air into the cylinders. However, as the patent points out, this means the intake compressor and the exhaust turbine are physically coupled, and have to spin at the same rate. Ferrari's design divorces the two, and it's a happy breakup. The key is hooking up the two components of the turbo to their own individual electric motors, with an energy storage device in between. It's different than the electric supercharger systems you have seen on certain Audi products, for example. Those systems recover energy like a hybrid, store it, and then use it to drive an intake compressor. It supplements conventional turbochargers that harvest energy from the exhaust. In systems like Audi's, the electric supercharger is supplementing the sequential conventional turbochargers when they're not operating efficiently, at very low RPM in particular. It works well, but it's complicated, and it is a workaround for the limitations of a conventional turbocharger. See below for an animation of the Audi system. This content is hosted by a third party.

A smaller compressor generates boost more quickly, but loses efficiency at higher RPM. But there's way more energy in high-RPM exhaust gasses. By hooking up the turbine to an electric motor instead, you can harvest energy from the exhaust throughout the rev range, and particularly when the engine is pushing lots of gasses through. And you can store that energy in a battery if it's not needed at that moment. The intake-side compressor also has a reversible electric motor attached. It is not physically connected to the turbine, so it can operate at any time the computers decide it's beneficial. As engine RPM increases, the compressor doesn't have to increase its speed beyond its optimal range, so there's less energy wasted. And at low RPM situations, when a conventional turbocharger wouldn't have enough exhaust gas passing through its turbine side to generate useful boost in the compressor side, the electric motor can spin up Ferrari's divorced compressor to provide some boost.

Nissan GT-R and Ferrari 458 Speciale in track battle by Evo

Supercar slayer. That's what they call the Nissan GT-R. And in many ways it is, even though its price and performance over the years have risen to put it squarely in supercar territory of its own right.
In fact, as Evo magazine has been compiling a list of its fastest cars - using the Anglesey Circuit in Wales as its common ground - the GT-R has came out on top... that is, until Evo tested the Ferrari 458 Speciale. The two are about as different as you can get within the supercar segment: one has a turbo six up front driving all four wheels in a 2+2 configuration, the other a mid-engined, rear-drive V8 two-seater. In fact the only common ground you're likely to find between them comes down to their two doors and dual-clutch transmissions. Though they serve it up in different ways, both are class-leading performers.
We're looking forward to watching Evo populate its leaderboard with more entries like the McLaren 650S and more potent Nismo GT-R, but in the meantime the British enthusiast magazine, by popular demand, has released side-by-side in-car footage of both supercars putting their best lap forward around the seaside circuit.

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.
