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.

Mansory La Revoluzione shows at least a little restraint

Mansory has, yet again, taken a supercar and turned the dial up to 11. Or maybe 12 or 13. This time the base car is none other than the Ferrari F12 Berlinetta, a V12-powered GT car. Compared to Mansory's previous Ferrari GT-based creation, the Rambo-inspired Stallone that had used both the 599 and 612 as its base, the new La Revoluzione is a welcome departure.
While the Revoluzione isn't what we'd call subtle, especially from the very front- and rear-most views, we appreciate the small amount of restraint Mansory showed when styling this deep red carbon fiber-bodied car, at least on the outside. As you can see in our image gallery above, the interior of this creation is quite loud and perhaps a little bit obnoxious.
We can't argue with the results seen underhood - claimed horsepower sits at over 1,200 from a twin-turbo 6.3-liter V12 engine. That many ponies pays the expected dividends in performance, with a 0-62 run of 2.9 seconds and a top speed listed at 230 miles per hour. See it yourself in our high-res image gallery above.

Two Ferrari LaFerraris are for sale in Dubai

You can rest assured that a disproportionate share LaFerrari production run headed to the United Arab Emirates. Of those, two examples of which are now listed for sale in Dubai alone on Dubicars.com. Both of them are red, which is no surprise. The first, pictured in the image gallery above, is a brand-new 2014 model for sale at the emirate's famed dealership Al Ain Class Motors. The 2014 model is listed with zero miles on the odometer, though we'd be surprised if it hadn't racked up at least a few delivery and test miles. All it will cost you is a small matter of 11,000 Emirati Dirham, which works out to a hair under $3 million at current exchange rates. GTR Motors hasn't listed how much it wants for this second example depicted in the video below. But you can bet that – even with 398 kilometers (or 247 miles) on the clock – this 2015 example will still command a significant premium over the $1.35 million the factory charged for these hybrid hypercars when they were new. If you can scrape together the cash for either, you'll be getting arguably the ultimate Ferrari road car to date, packing a 6.3-liter V12 hybrid powertrain good for 950 horsepower and a 2.5-second 0-60 time. The factory in Maranello only built 499 of them, so finding one – let alone two – up for grabs is a bit of a rarity. Of course if this particular Prancing Horse isn't your cup of tea, there's plenty of other enticing machinery on offer, including a McLaren P1, Koenigsegg CCX, three Porsche 918 Spyders, and a handful of Bugatti Veyrons.
