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: 2013 German Grand Prix is old beginnings, new endings [spoilers]

Just like at Silverstone last weekend, the German Formula One Grand Prix started with Lewis Hamilton putting his Mercedes-AMG Petronas on pole. The only thing missing at the pointy end of the grid was his teammate Nico Rosberg, who lined up beside him in England but back in 11th in Germany because of a team error in qualifying. So instead it was Vettel in the first Infiniti Red Bull in second, his teammate Mark Webber in third, the Lotus duo of Kimi Räikkönen and Romain Grosjean.
Again, just like at Silverstone - and Canada - Daniel Ricciardo used his magic beans to impress with the Toro Rosso, lining up in sixth, followed by Felipe Massa in the first Ferrari, Fernando Alonso in the second. Jenson Button in the McLaren, Nico Hülkenberg finished up the top ten.
When the lights went green, it didn't take long for the race to become a black-and-blue affair...

Ferrari family won't sell stake in company

Ferrari may be splitting off from the Fiat Chrysler Automobiles group and launching its IPO independently, but those stocks it's going to float are coming out of Fiat's hands. The small portion still held by the Ferrari family looks destined to stay in their control for the time being. According to the latest report from Reuters, Enzo's son Piero says he has no intention of selling any of the 10 percent interest he and his family hold in the company founded by his late father. "I have never sold and I have no intention of doing so," said Piero, as quoted in the report. Piero Ferrari is the illegitimate son of Enzo Ferrari and his mistress Lina Lardi. His half-brother Dino died in his twenties from complications associated with muscular dystrophy, and in accordance with Italian custom, Piero was only acknowledged as Enzo's heir after the death of the father in 1988. Representing the family's holdings, Piero still acts as vice-chairman of the company but devotes his day-to-day to running aerospace manufacturer Piaggio Aero.
