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.

Ferrari IPO may turn out to be good news for enthusiasts

Sergio Marchionne's strategy to spin off Ferrari from FCA and make the Italian automaker a publicly traded company has been met with ire from a vocal contingent of enthusiasts ever since rumors about the plan began to surface a few years ago. Some of these particularly pessimistic automotive pundits have voiced fears that with stockholders in the mix, it would not only spell the demise of the exclusive Italian supercar maker as we know it, but would in fact "ruin" the company. Call me dense, but I fail to see what the issue is. That isn't to say that I don't understand what's causing the fear. When profitability becomes a higher priority for a brand that's historically relied on exclusivity to keep its products in the highest echelons of desirability, there's a high potential for internal philosophical conflict. And then there are concerns about the sorts of products that Ferrari might develop that aren't the high-performance sports cars that the brand is known for. But individuals with those apprehensions seem to forget that Ferrari has already lent its name to a multitude of things that are not LaFerraris, 488 GTBs, or F12 Berlinettas, including clothing, headphones, and even laptops. But let's assume for a moment that the core anxiety is about future vehicles – including the unspeakable notion that Ferrari might develop an SUV. Why wouldn't Ferrari build an SUV, especially after seeing how incredibly successful that endeavor has been for Porsche? I think it's likely that Ferrari will put engineers to task creating some sort of crossover or high-rolling cruiser with room for the whole family at some point in the near future. And why wouldn't it, after seeing how incredibly successful that endeavor has been for Porsche? After all, the Cayenne accounted for more US sales in 2013 than the Boxster, Cayman, 911, and 918 combined, and it only gave up about a thousand units of sales last year to make room for the Macan crossover, the latter of which Porsche sold nearly as many of as it did Boxsters and Caymans. People want these vehicles, and they're willing to pay quite a bit of money for them. If we use Porsche's recent trajectory as a foreshadowing metric for what's in store for Ferrari, the future actually looks pretty good. After all, those SUV sales keep plenty of cash in Porsche's coffers for the low-volume projects that we enthusiasts love, like the 918 Spyder and the 911 GT3 RS.

Former Top Gear crew starts filming for Amazon show

We might have only a hint at the name and no exact date for a premiere, but fans can celebrate that Jeremy Clarkson, Richard Hammond, and James May are filming once again. Plus, it looks like every cent of Amazon's reportedly lavish budget is being put on the screen. A photo tweeted by Clarkson shows the three hosts standing proudly in front of a Porsche 918 Spyder, Ferrari LaFerrari, and McLaren P1 at a racetrack. Clarkson jokes that the show has just a "skeleton crew" but behind him stand several dozen people, a sophisticated-looking camera rig, and two big trucks. This definitely looks worth the anticipation of the premiere on Amazon Prime next fall. Hammond tweeted the same picture and wrote: "The band is back together and it feels brilliant."

Intriguingly, it appears that fellow British auto journalist Chris Harris is currently filming at the same track. He tweeted a photo to Clarkson of the McLaren doing a very smoky slide, while being followed by the other two hypercars. The Porsches in both photos wear the same red-and-white number 3 livery and have the same license plate number. In a later message, Harris was also clear that he wasn't filming there in connection with the trio's Amazon show. This content is hosted by a third party.
