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.

LaFerrari, McLaren P1, Porsche 918 and Agera R take to Assen

It's the show-down (sort of) we've all been waiting for. The battle of the hybrid hypercars from the performance powerhouses of Europe: Ferrari LaFerrari, McLaren P1 and Porsche 918 Spyder. No one publication has managed to get their hands on all three just yet, but this video has - and with a Koenigsegg Agera R thrown in for good measure.
The video was shot by our (unrelated) Dutch compatriots at Autoblog.nl at the TT Circuit Assen in the Netherlands. The track has played host to Champ Cars and all manner of racing bikes, but this could be the ultimate grid of actual production machinery that's ever lined up behind its start/finish line. Shame the weather was rainy and this unsurpassed array of supercars weren't really racing - more showing off for the crowds. But what a show it was. Scope out the footage in the video below.

Ferrari F50s duel in world's most improbable tug-of-war

If it wasn't obscene enough to go off-roading in a Rolls-Royce Phantom or rally driving a Ferrari Enzo, the Tax The Rich crew has gotten its hands on a pair of ultra-rare Ferrari F50 models to perform a tug-of-war battle, which we usually see reserved for pickup trucks. Only 349 F50s were ever built, but this video pits two of them against each other by attaching a rope to the front ends, throwing the shifter into reverse and punching the throttle.
As we've come to expect from this video troupe, the action starts off with plenty of gravel-chucking, dirt-road drifting before the two cars finally meet head-to-head. Scroll down to watch the 520-hp V12s screaming in reverse as the tires smoke away.
