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.

Sebastian Vettel rips Ferrari FXX K around Fiorano

Sebastian Vettel is without a doubt the most successful driver currently on the Formula One grid. He's won four world championships, 39 grands prix and taken pole position 45 times. That makes him the third most successful driver in F1 history, retired or active. And now that he's signed with Ferrari, he's driving for the most successful team in the series as well. That's good news for the tifosi, but it's also good news for Vettel. Because not only will he be driving one of the best cars on the grid, but he'll have access to some of the best wheels off of it, too. Case in point: This latest video released by the Maranello outfit, in which the multiple world champion takes the new FXX K out for a spin around Fiorano. The track-bound evolution of the hybrid LaFerrari hypercar, the FXX K is said to lap the circuit in 1:14, making it the fastest Prancing Horse this side of a purpose-built racer like the SF15-T he'll be piloting in the 2015 world championship. In short, it's a heck of a step up from the special-edition FX crossover Infiniti made for him when he was still at Red Bull. And while you might think it still wouldn't measure up to some of the race-winning single-seaters he's driven over the years, he does seem to enjoy the experience. At least it's got a bit more elbow room than what he's used to.

Why this 1964 Ferrari 250 GTO will sell for at least $45 million

A 1962 Ferrari 250 GTO by Scaglietti will be up for auction by RM Sotheby's in Monterey next month. Actually, perhaps "the" 1962 Ferrari 250 GTO would be more appropriate, because the list of its accomplishments, claims to fame and reasons for being extremely expensive are probably more than the rest. And by "rest," we mean 36. And by "extremely expensive" we mean an expected sale price of between $45 million and $60 million. View 47 Photos If you want to read in vivid detail about the car in question, RM Sotheby's provides a lengthy tale of "the world's most important, desirable, and legendary motor car." Trying to regurgitate it here really wouldn't do it justice. Instead, here are some of the bullet points. No. 3 of 36 Ferrari GTOs built. Known as 3413. Considered by experts to be one of the most authentic and original of those 36, all of which survive One of only 4 of those 36 to receive upgraded at the time with Series II GTO/64 body work by Scaglietti. It is more aggressive in appearance, more aerodynamic and many say attractive Won the 1962 Italian GT Championship First in class at the 1963 Targa Florio in its original body work First in class at the 1964 Targa Florio in the Series II body work you see today, as detailed in the Sotheby's story Won its class in the 1964 Targa Florio, helping Ferrari win the 1964 International Championship for GT Manufacturers More than 15 class and overall wins from 1962 to 1965 Last purchased in 2000 for $7 million – There's a reason German banks are suggesting adding a classic car to your investment mix. 3413 has actually been driven during that time, making appearances at countless classic events and vintage races Purchase includes exclusive access to some of the world's most prestigious events and rallies, including the GTO club and tours – Value! Currently fitted with a 250 GT engine block built to GTO specification to allow the car to be driven to those countless classic events and vintages races – The original block has been removed for preservation and comes with the car. This Ferrari's expected price of between $45 million and $60 million would make it the most valuable car ever put up for auction. A 1963 250 GTO sold for $70 million in a private sale. Another sold at auction in 2013 for $52 million, so the upper level of 3413's sale estimate definitely seems feasible. Related Video: This content is hosted by a third party.
