F1 teams to test titanium skid plates to reignite spark in series

The 2014 Formula One season opened with one overwhelming complaint - the cars didn't sound right. It sapped the excitement, despite the fact that this season has seen a number of truly thrilling races (Bahrain, Spain and Montreal all come to mind). Attempts have been made to restore some of the audible thrill of the cars, although efforts have remained unsuccessful.
If F1 can't fix the sound of the cars, then other methods need to be considered to restore its self-perceived lack of excitement. One of those involves fitting titanium skid plates to the cars in a bid to reintroduce the sparks that were so prevalent in the sport's past.
Mercedes-AMG and Ferrari conducted initial experiments with the new skid plates during early practice sessions for the 2014 Austrian Grand Prix. Kimi Raikkonen and Nico Rosberg had the plates fitted to different locations of their cars, in a bid to see which created the most dramatic sparks. Considering the photos the tests, though, neither Mercedes' nor Ferrari's setup really seemed successful, which is why you're seeing Johnny Herbert and his 1989 Benneton B188 up top.

Ferrari to debut new twin-turbo California in the spring

Ferrari hadn't made a turbocharged engine since the F40 ended its production cycle in 1992. But that all changed when it helped Maserati develop its new 3.8-liter twin-turbo V8. That turbo engine has so far been shoehorned into the Quattroporte, along with its 3.0-liter V6 cousin that also powers the smaller Ghibli. But soon it'll wear the Prancing Horse badge as further details emerge on the next-generation California.
Set to arrive in time for the spring (likely to be unveiled at the Geneva Motor Show in March), the new California will reportedly ditch its naturally-aspirated V8 in favor of a reworked version of the Quattroporte's twin-turbo unit, which at 523 horsepower and 479 pound-feet of torque is already considerably more muscular than the current California's 483 hp and 372 lb-ft.
The new California will likely be closely based on the outgoing model, but benefit from revised aluminum sheetmetal and an updated cabin with a new infotainment system - two areas in which the current model has scored low marks.

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.
