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.

The real Wolf of Wall Street's Ferrari Testarossa is for sale

In 2013, acclaimed filmmaker Martin Scorsese profiled the rise and fall of financial crook Jordan Belfort in the movie The Wolf of Wall Street, with Leonardo Di Caprio in the lead role. Now you can own an automotive piece of that fascinating real-life tale by buying Belfort's 1991 Ferrari Testarossa. According to the seller, Belfort bought the Ferrari in New York in 1991. He must not have driven it very much, though. There have been other owners since him, but the Testarossa still has only covered 8,300 miles. With its white exterior, your friends might think you're trying to emulate Sonny Crockett from Miami Vice, and the interior has beige leather, which still looks to be in great condition. To prove Belfort's ownership, the sale comes with his name and address in the warranty book and on supply invoices. There's even a set of matching luggage, and the seller allegedly found a $50 bill in one of the bags' lining. Even if Belfort didn't drive the Testarossa too much, he might have had some fun with it. According to the listing, "it was involved in a 'Wolf' moment as early as the original test drive." However, the seller will only tell the next buyer what that means. Belfort's Testarossa is currently for sale in Monaco for an undisclosed price, but as a car formerly used in the United States, it might not be too hard to bring back. If you do decide to buy Belfort's Ferrari, remember to treat The Wolf of Wall Street as a cautionary tale. Related Video:

Ferrari LaFerrari supercar to spawn Maserati LaMaserati?

CAR reports Maserati may benefit from the introduction of Enzo-succeeding Ferrari LaFerrari (shown below). According to unnamed parties, Maserati is keen to create a successor for the MC12 (above) based on the bones of the new Ferrari.
Details are about as scarce as they come, but CAR reckons Maserati has a few options when it comes to building its own supercar. Those include using the suspension, chassis and electrical systems of the Ferrari but with a unique carbon fiber body and without the LaFerrari's hybrid system. The new take on the MC12 could use a detuned version of the 6.3-liter V12 from the LaFerrari or stick a quad-turbo 3.8-liter V8 behind the front seats.
The latter option could see the next MC12 yield up to 900 horsepower, putting it within reach of its cousin as well as hardware like the McLaren P1. Of course, all of this - including our fanciful name in the headline - is just speculation for the time being. CAR says that if the machine makes its way to production, it would could cost well over $1.3 million.
