Watch the Ferrari LaFerrari get put through its paces by Top Gear and Evo

Do you know what today is? Well, besides being the anniversary of the signing of the Louisiana Purchase (thanks France!), Consumer Protection Day in Thailand and Michael Waltrip's birthday, April 30 marks the expiration of the first of two embargoes on the Ferrari LaFerrari.
That means you're probably going to see quite a bit on Ferrari's hypercar in the coming days. One of the first things we've stumbled across is this video from our friends at Top Gear. Now, this isn't Jeremy, James and Richard playing with the ultra-powerful hybrid (although it's probably only a matter of time before the LaFerrari arrives at Dunsfold), it's the TG magazine crew. It's best to think of the Top Gear video as an appetizer, though.
The main course comes from Evo, which has a far lengthier and more detailed spot, running a full 10 minutes of fun. Dickie Meaden samples the 900-plus-horsepower monster on both the Italian roads and the Fiorano test track. We won't spoil the outcome, so be sure to take a look below for both videos.

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.
