Ferrari LaFerrari is beautifully redundant

The successor the Ferrari Enzo has officially bowed. Ferrari pulled the sheets back on the oddly named LaFerrari at the 2013 Geneva Motor Show, calling the machine the "maximum expression" of what defines the automaker. In this case, that includes a 6.3-liter V12 engine with 789 horsepower married to a 160-hp electric motor. The combination is good for a full 949 hp and 663 pound-feet of torque, and Ferrari says the LaFerrari can punch to 62 miles per hour in under three seconds. Keep your foot planted and 124 mph will click by in a scant seven seconds, while top speed sits at a lofty 205 mph.
Engineers turned to a total of four different types of hand-laminatated carbon fiber to create a chassis that's both stiffer and lighter than would have otherwise been possible. With a 41/59 weight distribution, carbon-ceramic brakes and ultra-light calipers, the LaFerrari is unlike anything we've seen from the company to date. The automaker says its creation is the fastest in its long history. You can take a look at the in-depth press release below for more information, and be sure to check out the model's new site here.

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.
