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.

1959 Ferrari 250 GT California sells for nearly $18M, exceeding expectations

RM Sotheby's just wrapped up its auction in New York, where it sold off a pair of gorgeous silver roadsters, with one of them selling for the incredible price of $17.99 million. That car was a 1959 Ferrari 250 GT LWB California that we covered previously, and Sotheby's was only expecting it to go for between $14 million and $17 million. Apparently someone felt the car's rare aluminum construction and racing history was worth the extra cash. View 11 Photos The other roadster went for considerably less money but was notable because of its previous owner, late Apple CEO Steve Jobs. The car is a 2000 BMW Z8 that the tech mogul had for around three years. The final sale price only met expectations, though, at $329,500. The original auction estimate was between $300,000 and $400,000.

White Christmas: Miami Vice Ferrari Testarossa on eBay for $1.75M

Were the eighties responsible for more iconic television cars than any other decade? Without even thinking about it we can reel off B.A. Baracus' GMC van, the Knight Industries Two Thousand and General Lee, Hardcastle and McCormick's Coyote, Magnum P.I.'s Ferrari 308. That's before we dip into personal favorites like The Fall Guy's GMC and the Dodge Ram Power Wagon from Simon and Simon, or hop over to cartoons like Transformers, the GoBots and MASK. And then there was this, among the top rung of eighties memorabilia, a 1986 Ferrari Testarossa claimed to be one of two used in Miami Vice. You'll remember that the show began with James "Sonny" Crockett driving a black Daytona Coupe, but it was a replica built on C3 Corvette running gear. The story is that Ferrari sued the replica maker and made the show's producers an offer: blow up the replica on the show in return for two Testarossas to use. And that, it's said, is how Crockett's convertible got hit by a missile during an undercover assignment with an arms dealer. The original cars were Carbon Black, but the show's cameras couldn't keep up with them at night, so director Michael Mann had them painted white. For sale on eBay with a Buy It Now price of $1.75M, the seller says he has the all of the service history paperwork and documentation from Ferrari North America. According to the seller, he bought it about three years ago; before that, it was last sold in 1991 and sat in a Miami garage for years, so it has 16,000 miles on the odometer. The Hagerty Price Guide Report shows Testarossa values have nearly doubled in four years, but a pristine find should still only fetch about $93,500, just to make sure you're clear on the seller's Hollywood premium. Nostalgia awaits you in the gallery, and perhaps a new car at the link.
