Ferrari patent suggests one-off SP FFX

You remember that batch of patent drawings we brought you a couple of weeks ago showing an unspecified Ferrari coupe? The interwebs were ablaze in speculation over what the car depicted could be, and we've been watching them all until we landed on the one that seems to make the most sense.
While some speculated that this could be a new California, updated to look more like the F12 and FF, our friends over at Jalopnik suggest, with sound reason, that what we're actually looking at is what we figured in the first place: that this is a one-off FF-based coupe being built for a private customer.
Perhaps the single biggest indicator doesn't lie in the drawings themselves, but the detail that everyone else seemed to have missed: at the same time as these drawings were submitted, Ferrari filed for another patent with the Italian government for the name SP FFX and the logo pictured above.

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: Monaco Grand Prix makes the kettle boil [spoilers]

It's not hard to believe that 80 percent of the action at the Monaco Formula One Grand Prix happened didn't have to do with straight-up racing. Mercedes AMG Petronas wasn't expected to maintain its obscene advantage over the field with Monaco being a short track that rewards corner speed over top speed, but they still ruled two of the three Free Practice sessions.
Off the track, Mercedes driver Lewis Hamilton said he thought it should be easier to beat his teammate and that he was hungrier than his teammate. Then came qualifying and Mirabeau, when Nico Rosberg had set the pole lap in the dying moments of Q3, and as the final few drivers tried to best it on their last chance - including Hamilton, who said he was on the lap that would have got him pole position - Rosberg overcooked it into Mirabeau and brought out a local yellow, killing everyone's chance to better his time. Although the sun was shining in Monaco, the paddock got cold as ice; Rosberg and Hamilton didn't look at one another, speak to one another or touch one another. Rosberg said, "It was an honest mistake." After the race, a disbelieving Hamilton said to the press, "I wish you could have seen the data."
They still lined up first on the grid, though, Rosberg ahead of Hamilton, followed by Daniel Ricciardo and Sebastian Vettel for Infiniti Red Bull Racing, Fernando Alonso and Kimi Räikkönen for Ferrari, Jean-Eric Vergne in the first Toro Rosso and Daniel Kvyat in the second in ninth, split by McLaren rookie Kevin Magnussen in eighth, and Sergio Perez in the Force India in tenth.
