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 to stop supplying Maserati with its engines

The Ferrari Q1 earnings call was full of information, and perhaps the biggest revelation was that Ferrari is going to stop supplying engines to Maserati. CEO Louis Camilleri broke the news, and The Motley Fool posted a transcript of the whole call online. "Eventually, we will no longer supply engines to Maserati, which actually from our perspective is actually a good thing, both from a margin perspective, but also the fact that we can transfer a lot of the labor that's been focused on the engines to the car side of the business," Camilleri says. Maserati has used Ferrari engines (arguably, one of the most compelling reasons to buy a Maserati) in its vehicles since 2002, a little while after Fiat passed Maserati off to the prancing horse. The partnership continued as both Ferrari and Maserati were under the same house at FCA. Then when Ferrari was spun off from FCA in 2015, they kept the supply steady to Maserati. Those engines include a 3.8-liter twin-turbo V8, 3.0-liter twin-turbo V6 and a 4.7-liter naturally aspirated V8. Camilleri said Ferrari will officially stop in 2021 or 2022, with no intention of supplying anybody with engines beyond that. Of course, this leaves Maserati high and dry with no engines for its growing lineup. Maserati will have to reach into the FCA parts bin, find a new outside supplier or develop its own engines. Battery electric sounds out of the question. As of now, there doesn't appear to be a clear plan going forward. We've reached out to Maserati to see if they have any comment on the situation as it stands.

Ferrari F12 TdF shrieks like a banshee on the Gumball

With all the exotic metal (or carbon) participating in the Gumball 3000 rally each year, it takes something truly exceptional to turn heads. The new Ferrari F12 TdF is up to the challenge. For those who may have missed the reveal back in October (and this week's episode of Top Gear), the F12 TdF could very well be the ultimate naturally-aspirated twelve-cylinder Prancing Horse. And by "ultimate," we mean possibly the last, before turbochargers and hybrids take over Maranello completely. Named after the legendary Tour de France (for automobiles, not cyclists), Maranello's latest is based on the F12 Berlinetta, but like the 599 GTO before it, the TdF pushes the envelope even further. Its 6.3-liter atmospheric V12 revs all the way up to 8,900 rpm, producing a monstrous 769 horsepower and 520 pound-feet of torque along the way – enough, in other words, to put the Lamborghini Aventador SV (and most anything else) to shame. It'll reach 62 miles per hour from a standstill in less than three seconds, top out at over 211 mph, lap Fiorano faster than any road car this side of LaFerrari, and slide around all day and all night with its four-wheel steering system. And it screams. Don't take our word for it: turn up the speakers, hit "play," and listen to the F1-like shriek it emits out in the wild.
