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.

This is the amazing Christmas wonderland Ferrari builds for kids every year

Granted, when we think of a "Ferrari Christmas Wonderland" our dreams naturally manifest something like a red FF with a bow on the hood and keys on the seat, parked in front of a Fiorano Circuit that's ours for the day. A guy's gotta dream, right?
But, luckily for a lot of beaming children and their grateful, non-selfish parents, Ferrari's gift back to the people of Maranello is far more festive. The Italian automaker clearly pulls out all of the stops for its annual Kids Christmas party to celebrate the season. The event, which sees the Ferrari grounds transformed in to a veritable amusement park in a holiday theme, seems pretty massive of scale and impressive in its detail.

Marchionne hints at once-'obscene' idea: a Formula E electric Ferrari

Ferrari is certainly protective of its brand image, even if it means coming off as a Luddite. A year ago, Chairman and ( now) CEO Sergio Marchionne said that an all-electric Ferrari would be " almost an obscene concept," adding, "You'd have to shoot me first." So it's surprising to see him tell Auto, the FIA's magazine, that "we need to be involved" in all-electric racing series Formula E. Earlier the interview, Marchionne talks up Ferrari's need for electrification, at least in terms of incorporating more hybrid technology. "Hybridization is crucial to Ferrari," he says, not necessarily in meeting emissions targets, but for performance. Ferrari will use new technology, electrification included, in future models, with a focus on creating an emotional experience for the driver. Late last year, Marchionne said that the brand would leverage hybrid technology to boost production figures and profits, and that every model would offer some hybrid technology by 2019. When asked about the likelihood of Formula E entry, Marchionne says, "It's difficult to say." He then adds, "We need to be involved in Formula E because electrification via hybridization is going to be part of our future." What that level of involvement would be is also uncertain, but he didn't rule out the possibility of a Ferrari Formula E racer, which would by necessity be all-electric. Of course, Ferrari could find a development role in the race series without entering its own vehicle. Regardless of the type of involvement, Ferrari's reputation could stand to gain from representation in the series, especially if it means it's not appearing to fall behind the likes of McLaren, Jaguar, BMW, and Audi, who have all played a part in Formula E. Either way, it appears that Marchionne is warming up to electrification, and that the idea of an all-electric Ferrari – even if it's confined to a single race series — isn't quite as obscene as it once seemed.
