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.

What next for Stefano Domenicali?

Ferrari is a team that's used to being on top. It does, after all, have more world championships to its name - 15 drivers' titles and 16 constructors' - than any other team in the history of Formula One racing. But despite having some of the best drivers and resources at its disposal, it hasn't won a championship in over five years. Someone had to take the blame for that, and that someone turned out to be Stefano Domenicali.
The team principal who took over after Jean Todt stepped back to focus first on the running of the entire company and then the FIA, Domenicali has presided over the driest spell in the team's history since Michael Schumacher and Ross Brawn arrived in the late 90s to bring Ferrari back to its winning form. Whether that ultimately proves to have been Domenicali's fault or not, the buck stopped on his desk and he resigned a couple of weeks ago, making way for Ferrari's North American chief Marco Mattiacci to take the reins. At least for now, anyway, as rumors circulate of a longer-term solution that could bring Ross Brawn back into the fold following his recent departure from Mercedes.
The big question now, however, is what Domenicali will do next. The latest intel suggests that he could leave four wheels behind but stay in the field of competitive sports to coach an Italian basketball team. The rumors are fueled by reports that Domenicali has been in touch with Giovanni Petrucci, head of the Federazione Italiana Pallacanestro - Italy's national basketball federation. The organization runs two professional basketball leagues within Italy as well as its national team that's won eight international championships, two gold, four silver and four bronze medals in the European league and two silver medals in the Olympics.

Intel-Mobileye tech in 2M BMWs, VWs, Nissans will crowdsource maps for autonomy

Intel Chief Executive Brian Krzanich said on Monday 2 million vehicles from BMW, Nissan and Volkswagen would use its unit Mobileye's technology to crowdsource data for building maps that enable autonomous driving. The world's largest chipmaker bought Israeli firm Mobileye last year to compete with peers such as Qualcomm and Nvidia Corp and tap the fast-growing market of driverless cars, filled with a complex tangle of alliances. (VW, for example, is also working with Nvidia.) Krzanich was the keynote speaker at the Consumer Electronics Show. He said data from Mobileye's Road Experience Management software would gather data to build and update scalable high-definition maps. He also announced that Intel would be working with Ferrari on AI drones to cover Ferrari Challenge North America Series racing. The drones would provide video of the races, but ultimately they would provide drivers with data — video that would let them see their racing performance from overhead, but also telemetry information about, say, how they enter and exit a turn. Intel will also tie up with SAIC Motor Corp, which will use Mobileye technology to develop Level 3, 4 and 5 autonomous cars in China, the chipmaker said. Krzanich also said Intel had not received any information of customer data being compromised so far after the company confirmed last week that security issues reported by researchers in its widely used microprocessors could allow hackers to steal sensitive information from computers, phones and other devices. Security researchers had disclosed two security flaws exposing vulnerability of nearly every modern computing device containing chips from Intel, Advanced Micro Devices and ARM Holdings.
