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.

Ferrari production to increase under Marchionne

The head of any company has to juggle the relationship between supply and demand. Of course, that applies to automakers too, even ones as high-end as Ferrari. And as with many other decisions, the way Ferrari has addressed supply and demand has come down principally to the principal.
Enzo Ferrari may have only wanted to sell as many vehicles as he needed in order to fund his company's racing department, but with the F40 - the last model made under his watch - Ferrari ended up increasing supply to meet growing demand. However, after Luca di Montezemolo took over in the wake of Enzo's passing, he started constricting supply. He figured Ferrari could sell 400 units of the F50, for example, so he built 399. More recently, Montezemolo undertook a course of action that spread Ferrari into more markets, while simultaneously constricting supply to increase demand and thereby profitability.
It's been a winning formula for Ferrari. Just days ago, the company announced record earnings up by 14.5 percent in the first half of 2014 over the same period last year, which itself had seen a 7.1-percent increase over the year before. Clearly the strategy has worked, but Montezemolo's successor is already eying a different approach.

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.
