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 testing 458 successor in the snow?

It may not seem so long ago that Ferrari introduced the 458 Italia. But it's been on the market a solid 5 years since its launch in 2009, which makes it not only the oldest model in the company's lineup, but one of the oldest in its segment, the Lamborghini Huracan and McLaren 650S just having been launched in the past couple of months. So while a solitary Ferrari playing in the snow might otherwise seem like little more than an unlikely place for it to be, its chronology suggests the crew from Maranello could be up to something more.
The white 458 captured by our spy photographers in Northern Sweden appears to have something going on around its wheel arches. Aside from the panel gap that's taped up between the quarter panel and rear fender in front of the rear wheel arch, there appear to be some modifications around the front wheel arch. Just what they're for, we don't know, but their presence suggests something's up.
The test mule pictured here could be simply testing some new components, for whatever application, but if this is indeed a prototype for the 458's replacement, we'll probably start seeing more of these from here on in before the finished product comes around within the next couple of years - by which time the 458 will be a good seven years old, longer than the F430 or 360 Modena before it were on the market.

Ferrari considering return to Le Mans racing in 2015

Rumors are swirling that Ferrari may be contemplating a return to Le Mans racing as soon as 2015. Germany's Auto Motor und Sport reports the Italian automaker may apply the development of a new 1.6-liter turbocharged V6 engine for Formula One to an LMP1 car for Le Mans, and have it ready for the 24 Hours of Le Mans in two years. This follows hints made by Scuderia Ferrari CEO Stefano Domenicali last month that the newly developed F1 engine could be used for "some interesting projects."
Ferrari has a history of success in Le Mans racing, though it hasn't won the big endurance outright since 1965. The image above captures the exact moment when the No. 21 car of Masten Gregory and Jochen Rindt crossed the finish line that year to win the race. That win was the last of six consecutive outright victories before the infamous arrival of the Ford GT40 in 1966. Despite never reaching the top of the podium again, Ferrari's nine wins still stand as the third most overall by a manufacturer behind Porsche (16) and Audi (11).
If Ferrari does return to Le Mans in 2015, the LMP1 class will suddenly be teaming with worthy competitors for Audi, which has dominated the race since 2000. After Peugeot's exit from the sport in early 2012, Toyota entered the race in 2012 and has continued to develop its TS030 Hybrid LMP1 car. Porsche, meanwhile, is well into developing a new LMP1 car that will first compete in next year's race.
