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 threatening to fine journalists $69,000 for breaking LaFerrari embargo?

In automotive journalism, we deal with embargoes on a regular basis. For the uninitiated, these are agreements between publications like Autoblog and manufacturers. While news embargoes (where pubs are provided with information and images and agree to hold until a predetermined date) are fairly common, today, we're focusing on drive embargoes. These are what we generally end up signing when we attend a vehicle launch. Generally, these are in the media's best interest. As drive programs are spread out over a week or two with multiple different "waves" of media, drive embargoes put the biggest and smallest publications on level footing when it comes to publishing reviews.
According to a report from Autocar's Steve Sutcliffe, Ferrari has taken its drive embargo for the LaFerrari hypercar a bit too far. See, initial reviews from the few publications that attended the drive event for the hybrid-powered monster can hit the newsstand or internet on April 30. Originally, syndicated stories - those sold by freelancers or publications to other outlets - couldn't be published until May 12. These syndicated reviews are big money for larger magazines and, in the case of freelance journalists, are a primary source of revenue. Inexplicably, though, Ferrari has pushed the syndication embargo back to May 26, which is bad news for everyone involved (aside from Ferrari).
This could have been nothing more than an annoyance. The stories would still get sold (although it might be for a bit less coin, considering the initial reviews will be nearly a month old) and you'll still be bombarded by reviews of the LaFerrari not once, but twice, just as Ferrari planned.

Ferrari 458 Speciale is our Frankfurt fantasy [w/video]

This is the Ferrari 458 Speciale, and while its name might underwhelm, its performance and lineage more than make up for it. The successor to the proud line of hot, higher-performance, mid-engined Ferraris like the 360 Challenge Stradale and 430 Scuderia, the 458 Speciale is blessed with a 596-horsepower, 4.5-liter V8 and the ability to skip to 62 miles per hour in three seconds. It also comes with a not-so-subtle racing stripe, which we like.
Thanks to a scarcely believable curb weight of 2,844 pounds, special Michelin Pilot Sport cup 2 tires, and a few tweaks to the electronic diff, the Speciale is quite a dancer as well. Naturally, Ferrari is showing off the newest member of the scuderia at Frankfurt, and we made it a priority to see it in person. We've got a full gallery of live images above, a video and stock photography from Ferrari down below, and our original coverage of the car, from August, right here.
