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.

Seinfeld's Porsches, '61 Ferrari lead the way at Gooding Amelia Island sale

If you're in the market for a sports car with celebrity provenance or just an incredibly well-preserved high-performance machine, then you'll want to check out Gooding & Company's Amelia Island auction in Florida on March 11. The highlight of the sale is likely 18 cars, mostly Porsches, from Jerry Seinfeld's collection, but there's more to see than just the comedian's sporting metal. While several of Seinfeld's cars carry auction estimates in the millions, they aren't the most valuable at the sale. That honor falls on a 1961 Ferrari 250 GT SWB California Spider, which could sell for between $15 million and $17 million. This one is among the 37 examples with covered headlights, and it has some theatrical provenance after appearing in the Sophia Loren film Yesterday, Today, Tomorrow. If your tastes skew more American, then one of 31 Ford GT40 MKI road cars is also among the lots. Gooding expects the rare coupe to sell for between $3.2 million and $3.6 million. Ford originally used this GT40 for dealer promotions, but it eventually fell into private hands. Even today, its multiple owners have only covered around 3,200 miles in it. Gooding also expects a 1931 Duesenberg Model J Disappearing-Top Convertible Coupe with a body by Murphy to bring $2.5 million to $3 million. The auction house claims this might be the "most original" example left because of a history of owners who kept it for long periods – and the vehicle never needed a complete restoration. Some lots carry more attainable estimates like $35,000 for a 1962 MGA. You can check out all the listings on Gooding's online catalog and some of the highlights in the gallery above. You've probably read the news about Seinfeld's Porsches, but here's a refresher: The collection includes amazing cars like a 550 Spyder, 917/30 Can-Am Spyder, and a 718 RSK. Related Video:

Ferrari Purosangue SUV test mule spied in video

We all know Ferrari has lost its shame and is working on an SUV, but here's the first hint of it with this video of what's most likely a Purosangue test mule. Yes, Ferrari Purosangue is the terrible name reportedly being given to the upcoming vehicle that Ferrari will not want you to call an "SUV." But what we're looking at here is the body of a GTC4Lusso with some obvious SUV hints. Just look at the ground clearance and wheel gap on this thing. That's clearly not typical Ferrari style. The video was captured by SupercarsNews on YouTube, and is actually quite comical too. As soon as the driver of the Ferrari notices the videographer standing by the fence, he jumps on the brakes and backs out of there behind the cover of trees. All was for naught, however, because we got to see and hear the test mule anyways. We don't imagine the Purosangue SUV/crossover thing will end up looking like this when it comes out. It is the first physical "proof" of the Ferrari utility vehicle, though, with a launch sometime early in the next decade forthcoming. Unfortunately, the quality of the video is on the poorer side of things, so it's difficult to pick much out beyond the high ride height. The sound of a modern Ferrari engine is evidently there — we wouldn't doubt this car being offered with an electrified powertrain too eventually. There's no information on where this video was shot, but chances are the videographer is right next to Ferrari's home in Maranello with this kind of a vehicle out and about. So go ahead and watch the video above -- it's a pretty weird sight to see a lifted Ferrari. Related video: Rumormill Spy Photos Ferrari Crossover SUV Luxury Performance
