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.

Autoblog Minute: Ferrari F12 TdF, Tesla Autopilot, Fiat brand leadership change

Ferrari unleashes the F12 TdF, Model S owners get an exciting announcement from Tesla, and Fiat North America undergoes a leadership change. Senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Ferrari unleashes the F12 TdF, Model S owners get an exciting announcement from Tesla, and Fiat North America undergoes a leadership change. I'm Senior editor Greg Migliore, this is your Autoblog Minute Weekly Recap. Ferrari's new F12 TdF gets its name from the legendary Tour de France race that Ferrari dominated back in the 50s and 60s. [00:00:30] This new Ferrari is derived from the naturally aspirated F12 Berlinetta's engine. There are styling and performance upgrades, and the company highlights changes in aerodynamics, weight reduction, and faster shifts. The result, Ferrari says, is a blistering zero to sixty-two time of, 2.9 seconds. It's pretty fast. Tesla released software version 7.0 for Model S owners. The big takeaway from this update is the much anticipated Autopilot mode. Tesla says Autopilot [00:01:00] allows Model S to steer within a lane, change lanes, and manage speed. Software version 7.0 will also allow for digital control of the motors, brakes, and steering for collision prevention. Now do you hate parallel parking? Tesla's got you covered. The Model S can park on command, right after it scans for a spot and alerts you when one becomes available. Jason Stoicevich resigns shortly after losing control of the Fiat brand. Automotive News reported that Stoicevich's leadership role at Fiat was handed over to the company's [00:01:30] head of the Dodge brand. That's Tim Kuniskis. The report cites diminished sales figures as a key reason for the personnel change at Fiat. This change resulted in Stoicevich leaving FCA altogether. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. Plus I'll have some added insight into BMW's M2. For Autoblog, I'm Greg Migliore.

Berger and Vettel swap F1 cars old and new at the Red Bull Ring

This weekend the Formula One circus heads to Spielberg. No, not the Hollywood director, but the town in Austria that's home to the Österreichring. Subsequently known as the A1-Ring, these days it's called the Red Bull Ring, which makes this weekend's revived Austrian Grand Prix something of a home race for the defending champion Red Bull Racing team. But long before that it was the home race of the sixteen F1 drivers that call Austria their home - not the least of them Gerhard Berger.
The only Austrian driver to have won a grand prix (ten of them, all told) but not a championship, Berger was a fixture of F1 racing in the 1980s and 90s, spending much of his career driving for Ferrari. He later ran Scuderia Toro Rosso for three seasons, during which time Sebastian Vettel won his first (and still the team's only) grand prix. So with the Austrian Grand Prix back on the calendar for this weekend, the two highly accomplished drivers headed to the Red Bull Ring for a little juxtaposition.
Gerhard rolled in with the Ferrari F1/87-88C in which he won the 1988 Italian Grand Prix at Monza (which was, incidentally, the same race that Vettel won for STR twenty years later under Ferrari power), and Seb in his championship-winning RB8. Then they switched off, giving the four-time world champion his first chance to drive a grand prix racer with three pedals. If you can't believe that, it's also (as far as we can tell) the first time, despite years of neck-and-neck competition and retention of some of the best drivers on the grid, that a Red Bull or Toro Rosso driver has driven a Ferrari F1 car, and vice versa. See how it went down in the video below.
