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 250 GT SWB California Spider tops Gooding's Saturday auction at $15.18 million

During the weekend's automotive smorgasbord in Pebble Beach, Ferrari has played a huge roll. Twenty examples of the ultra-rare 250 TR, better known as the Testa Rossa, were prominently on display at the Concours d'Elegance, and the Prancing Horses have been top sellers at many of the auctions. You can chalk up one more on that list with a 1961 Ferrari 250 GT SWB California Spider with a scarce, optional hardtop included going for $15.18 million at Gooding & Company's sale on Saturday night. Ferris Bueller would find it so choice.
In all, the auction house brought in about $60.4 million during the night, and 17 of the cars on the block sold for over $1 million. None of the other cars on Saturday managed quite the stratospheric highs of the California, though. A 1955 Aston Martin DB3S was the second-highest seller at $5.5 million. The next four top vehicles were all Ferraris with final prices ranging between $2.09 million and $2.365 million. Clearly, investors are in love with the Prancing Horse these days.

Totaled Ferrari Dino sculpture sold for $250k

How much would you pay for a Dino? Although this sub-brand was supposed to offer lower-cost alternatives to more expensive Ferraris, a 246 GTS model with "chairs and flares" can fetch big bucks. The later, more angular 308 GT4 is less desirable, but the one above just sold for $250,000. Oh, and it's a complete wreck - an absolute write-off, as you can see. So how did it fetch a quarter million when it wouldn't be worth that much in pristine condition? Because this is art.
"Objet trouvé", to be specific, the French term for a common object elevated to a work of art. That's the way it ended up displayed by celebrated French artist Bertrand Lavier and the Galerie Yvon Lambert at the Foire Internationale d'Art Contemporain (FIAC) art fair at the Grand Palais in Paris last week, where an unnamed Turkish collector paid the landmark price. Let's hope he's not planning on restoring it, because it's apparently worth more totaled.
