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.

Trump's old Ferrari F430 sells for $270,000

You may remember that Auctions America was going to sell a 2007 Ferrari F430 owned by the current president of the United States. It was estimated at between $250,000 and $350,000. It went for auction this weekend and just barely fell into that range. According to Bloomberg, Donald Trump's old Ferrari failed to meet the reserve, set at $250,000, with a final bid of $240,000. However, Auctions America said the car sold after the auction at $270,000. So the auction company did get its estimate right, but just barely. As for what the new owner purchased, he or she got an F430 with celebrity and presidential heritage, the F1 automatic gearbox, low miles, a service history, and a classic Ferrari red paint job. Of course we still stand by our preference for a manual one in our choice of color and without any celebrity history (or baggage depending on your opinion). Check out our original piece for more details on the car. Related Video:

Listen to the Ferrari 488 GTB for the first time

We've received the initial information, seen it on the floor of the Geneva Motor Show and even played around with the online configurator. The one thing we haven't seen (or heard) just yet is the new Ferrari 488 GTB actually firing up. (Well, that and driving the thing, but let's not get ahead of ourselves.) Fortunately some paparazzi with a video camera have caught the new mid-engined, eight-cylinder Ferrari undergoing testing – still under wraps despite having already been unveiled – in Maranello, entering and exiting the factory. And in case you were worried that the twin turbochargers would muffle the exhaust note, it seems the boys in red have invested some time making sure that wouldn't be an issue. Not only that, but we appear to have here our first glimpse at the convertible version, expected (in accordance with traditional Ferrari nomenclature) to be dubbed the 488 GTS – that S standing for Spider instead of the B for Berlinetta. Expect a similar folding hardtop mechanism to that found on the outgoing 458 Spider. Then again, the last time the GTB handle was used on this line was with the F355, where the GTB was the coupe, GTS was the partial convertible with the removable roof panel, and the full convertible was called the F355 Spider. (The more recent, twelve-cylinder 599 GTB Fiorano only led to the limited-edition 599 SA Aperta, as Ferrari doesn't typically offer twelve-cylinder roadsters in "regular" production.)
