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 250 Testa Rossas assemble by the shore at Pebble Beach

Seeing one Ferrari 250 Testa Rossa could be a once-in-a-lifetime experience for many people because so few exist, and those that do generally trade hands for tens of millions of dollars. At this year's Pebble Beach Concours d'Elegance, there are 20 of these amazing rarities lined up next to each other.
Situated right on the shore of the Pacific Ocean, you can actually hear the waves lapping against the rocks during the quiet moments. Just a few feet away these thoroughbred Prancing Horses are on display and being polished to perfection. The Testa Rossas represent some of the most important historic racers in the world, and the mix here include a prototype, a Le Mans winner and models that counted drivers like Phil Hill and Dan Gurney behind the wheel.
Not all Testa Rossas were created equal, though. Ferrari built both factory racing and customer versions, and they came with curvaceous bodies from Scaglietti and a bit more angular look with dual snouts from Fantuzzi. Many of them also had further modifications from there to make each one about as unique as a snowflake. Check out our fabulous gallery of all 20 of these beautiful red heads on display together.

Ferrari California replica from Ferris Bueller is so choice

We like car auctions well enough, but often the high-end affairs are a bit too much like outdoor museums - very beautiful and very cold, and you're not allowed to touch anything. A perfect case in point is the upcoming Mecum auction during the 2013 Pebble Beach weekend, which will feature the legendary replica Ferrari 250 GT California Spyder used in none other than Ferris Bueller's Day Off. Only three were made. The current owner spent ten years restoring this car. It is his love, it is his passion. (Well, it was before he decided to auction it, anyway.)
Actually built by Modena Design and Development in El Cajon, CA, the official name of the stunning replica is Modena Spyder California. Built up on a tube frame, with a meticulously maintained interior and powered by a 500-horsepower small block V8 the car is so choice. If you have the means, we highly recommend picking one up.
Mecum hasn't suggested a predicted auction price for the Hollywood relic as of yet, but with the perfect pedigree to pull Gen X heartstrings, and the proliferation of stupid-wealthy fourtysomethings in and around northern California, we wouldn't be surprised to see a decent value. Just don't wait on it, life moves pretty fast around Pebble Beach. If you'd like to read a full description of the car with fewer script-quotes, look, it's real simple, scroll down.
