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.

Ferrari third-quarter profit doubles on one-off tax break

MILAN — Ferrari says its net earnings doubled in the third quarter thanks mostly to one-off tax benefit. The sports car maker said Monday that net earnings were 287 million euros ($327 million) compared with 141 million euros a year earlier. The company said earnings grew 5 percent when excluding the so-called patent box tax break, agreed on with Italian authorities, covering use of copyrights, patents, trademarks, design and know-how. Deliveries were up 11 percent to 2,262 vehicles driven by sales of the 812 Superfast and the Ferrari Portofino, with revenues flat at 838 million euros. Europe and Middle East sales were up by double digits to 1,005. The Americas grew by 5 percent and greater China by 7 percent. Ferrari forecast full-year sales at over 9,000 cars with profits of 1.1 billion euros.Related Video:

Ferrari names Edwin Fenech head of North American office

Ferrari North America has been sailing without a captain for the past several months since its previous chief executive, Marco Mattiacci, was called home to Italy to run the Scuderia. But now the Italian automaker has announced a new capo to run the office in New Jersey, and his name is Edwin Fenech.
Not to be confused with the French-Italian actress Edwige Fenech (who obviously showed up in our research before the Ferrari exec did), Edwin Fenech has a long history of running regional offices for the Prancing Horse marque. Prior to making the jump to the North American division, Fenech ran the company's operations in the Middle East, Africa, Asia Pacific and China, and previously served as sales and marketing director for France and sales manager for all of Europe.
Now in charge of Ferrari's largest market, Fenech will be responsible for expanding the company's presence not only in the United States - in which Ferrari has been present now for sixty years - but also in Canada as well as Central and South America.
