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.

Race Recap: Belgian Grand Prix is new skirmishes, same war [spoilers]

It's been four weeks since we last saw a Formula One race, when Lewis Hamilton improbably put his Mercedes-AMG Petronas in P1 in Hungary. Even more improbably, he held onto the first spot at the finish of the race, ahead of Kimi Räikkönen in the Lotus and Sebastian Vettel in the Infiniti Red Bull.
Resuming the season at Belgium's Spa-Francorchamps circuit this weekend, Hamilton picked up his recent - and just as improbable - pole-setting form by putting the Mercedes in P1 for the fourth time in a row. The effort came during a qualifying session visited by intermittent rains and dry spells, his 54th trip to the front of the pack, tying Niki Lauda.
But neither the fireworks and surprises, the mid-field full of backmarkers, nor the tire strategies and timing choices changed the mission for the drivers in with a chance at the title: finish in front of Vettel.
