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.

Race Recap: Brazil ends the 2013 F1 season with whimpers, bangs [spoilers]

When the grid lined up at the Autódromo José Carlos Pace in Brazil there were just 71 laps, almost 306 kilometers, until the end of the 2013 season. Sometimes the circuit in Interlagos is deciding a Championship winner or showcasing new talent, and sometimes it's merely deciding a winner. This year was the latter.
2013 World Champion Sebastian Vettel in the first Infiniti Red Bull Racing lined up in front of Nico Rosberg in the first Mercedes-AMG Petronas, Fernando Alonso in the first Ferrari, Mark Webber in the second Red Bull and his final Formula One race, Lewis Hamilton in the second Mercedes, Romain Grosjean in the Lotus, Daniel Ricciardo in the first Toro Rosso and his final race for the team before moving to Red Bull, his teammate Jean-Éric Vergne, Felipe Massa in the second Ferrari and Nico Hülkenberg in the Sauber.
There were numerous theories about what surprises might occur, with race day being the first dry running of the weekend and rain predicted to fall at some point during the running. The first surprise came when the lights went out and Vettel, the consummate starter, got beat to the first corner.

F1 driver underestimates talent needed for wet-weather burnout

Whoops. That's a word nobody wants to hear in racing, and that's especially true in Formula 1, where the cars cost untold millions to design, develop, build and operate. In other words, just about any 'whoops' is an expensive 'whoops.'
Kamui Kobayashi, who made his F1 debut in 2009 driving for Toyota, has always been known as a bit of a wild card in the sport. He is notoriously difficult to pass, driving as he does with seemingly reckless abandon, and he's not afraid to get tangled up with the world's best drivers in the world's fastest race cars.
That brash attitude sometimes serves him well. Other times... well, not so much. See what happens with Kobayashi tries to show off in a Ferrari F1 car for fans on a wet track in Moscow in the twin videos below.
