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.

Ex-Ferrari chairman sounds off on IPO

Former Ferrari chairman Luca di Montezemolo preferred to put exclusivity over profits when he ran the company, and the lower volume still meant huge amounts of cash for the business. FCA CEO Sergio Marchionne has since taken over Ferrari, but that hasn't stopped di Montezemolo from voicing his opinions. "I hope that the clients will remain more important than the analyst or the investor or the financial markets," di Montezemolo said prior to his induction into the Automotive Hall of Fame in Detroit, the Detroit Free Press reported. The former chairman argued that once on the stock exchange, a company would need to maximize profits quarter after quarter to keep investors happy. Conversely, di Montezemolo said Ferrari's years of success came from an "exclusivity in terms of number of cars, exclusivity in terms of how you deal with the clients." When di Montezemolo left Ferrari last year, he and Marchionne were scuffling about the future of the brand, including the health of the Formula 1 program. With the change in leadership, the company has reversed course in some ways. Where volume was previously kept around 7,000 units annually, the carmaker has set a new goal of closer to 10,000. The paperwork was filed for the IPO, and Marchionne thinks the company could be worth over $11 billion. The actual shares are rumored to go on sale in October. Related Video:

Mansory Stallone makes a man out of Ferrari F12

The Mansory Stallone you see above isn't the first such transmogrification of a Prancing Horse. This one is based on the Ferrari F12 Berlinetta, but the first honor, as far as we can tell, went to the Stallone based on the 599 GTB Fiorano. The F12 version was unveiled at the Geneva Motor Show this year, but we missed out, and we were sure you wouldn't want to miss it.
As with its predecessor, this one gets a total makeover, from the new front clip and hood to the side skirts, new rear end, rear diffuser and rear wing. There is additional muscle for the 6.0-liter V12, too - a tweaked ECU and sports exhaust with a stainless steel muffler getting matters up from 740 horsepower to 775, and torque from 509 pound-feet to 535. Moving things forward is a set of bespoke, staggered, lightweight aluminum wheels, 21 inches up front, 22 in the back.
The showstopper is inside, where a red and black leather treatment and redesigned steering wheel will make the cabin a very intense place to be. Check out the press release below for the minutiae, and the high-res gallery above for more angles.
