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.

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.

Lewis Hamilton on pole in France, Sebastian Vettel only seventh

LE CASTELLET, France — Lewis Hamilton seized pole position for the French Grand Prix in track record time as Mercedes, chasing their 10th successive win, swept the front row of the grid in dominant fashion on Saturday. The Formula One world championship leader was 0.286 seconds quicker than team mate Valtteri Bottas. Ferrari's Charles Leclerc qualified third with team mate Sebastian Vettel a distant seventh on a distinctly off day for the German. The pole, in a time of one minute 28.319 seconds, was a record-extending 86th of Hamilton's career and his third of the season. "I'm happy that I got the potential out of the car, the team did a fantastic job," said five-times world champion Hamilton, last year's winner from pole at Le Castellet's Paul Ricard circuit. "We've just been chipping away at improving the set-up of the car," added the Briton, who is 29 points clear of Bottas after seven races — all won by the pair. Hamilton also triumphed in the last two of 2018. Bottas was fastest in the second phase of qualifying but could not match Hamilton's sizzling pace when it mattered in the final shoot-out. "The wind changed direction and there was a couple of corners my line didn't work and I had to work it out but Lewis had a better lap," said the Finn. Mercedes have looked to be in a class of their own all weekend, with Hamilton or Bottas fastest in every practice session with Leclerc, rather than Vettel, consistently the best of the rest. Vettel struggled, backing out of his first hot lap and then failing to string together all the sectors smoothly on his second attempt. "I don't know what happened, I lost so much momentum there was no point to finish that lap," said the German, who starts behind the Renault-powered McLarens of British rookie Lando Norris (fifth) and Spaniard Carlos Sainz (sixth). "Some laps it felt good and others it didn't. I didn't get the best out of the car but it was difficult for me, but some laps I didn't have he grip I had before." Vettel's time of 1:29.799 was eighth tenths of a second slower than Leclerc's best. Leclerc, who starts with Red Bull's Max Verstappen alongside, asked the team over the radio to get Vettel to speed up but the Monegasque said his lap had not been compromised. Australian Daniel Ricciardo starts eighth for Renault and Red Bull's Pierre Gasly lines up ninth for his home race with Italian Antonio Giovinazzi 10th for Alfa Romeo.
