Ferrari replacing fuel tanks on limited number of LaFerraris

Ferrari is working to repair an issue with its flagship LaFerrari hypercar, but the automaker claims the problem is not as drastic as some widely-circulated rumors would have you believe. In response to our inquiry into the matter, a Ferrari spokesperson told Autoblog that "no recall has been issued regarding the LaFerrari." Instead, the company tells us that "some clients have been invited to take their cars to an authorized service center to substitute the fuel tank with a new one with new paint." The issue seems to revolve around "a possible incorrect adhesion of a layer of paint on the fuel tank," which could result in a fire. Contrary to rumors that suggested the issue would affect every example of the seven-figure supercar built to date and would take several weeks to repair, we're told that "the time to change the fuel tank is relatively short and the intervention concerns only a limited number of LaFerraris." That "relatively short" time period, we're told, "takes approximately one day," and "all of the cars have already been serviced in the US." As to whether this constitutes a recall or simply a suggested service as Ferrari claims, however, is a matter that's open to interpretation. Related Video:

Ferrari developing V-twin motorcycle engine?

When we read reports that Ferrari had applied for a patent on a V-twin engine design, our first thought was to check the date: this says the first of October, right... not April? And so here we are, entertaining the notion that Ferrari could be developing a motorcycle engine.
The report comes from Autocar, which claims to have dug up the application to patent the design for an "internal combustion engine having two cylinders, which are arranged in a 'V' configuration." In other words, a motorcycle engine. The application reportedly goes on to describe a balancing shafts to reduce vibration. Our own research did not lead us to find the application in question, so we'll have to take it with a grain of salt for the moment. But supposing it's all on the up and up, and that Ferrari was actually developing a motorcycle engine. Would that be so out of the ordinary?
Well, yes and no. Parent company Fiat, which is taking increased direct control of Ferrari, is undoubtedly looking at rival Volkswagen and its recent acquisition of Ducati (putting it in close proximity to Lamborghini) and would be keen to get in on that action. However tenuous the relationship, Lotus has also recently authorized a motorcycle bearing its name. And of course automakers like BMW and Honda, with which Ferrari has competed on and off the race track, also make motorcycles.

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.
