1955 Belgian GP movie tells the story of Spa

With the Belgian Formula One Grand Prix happening this weekend, Shell reminded a few guests what the Spa-Francorchamps track and Belgian countryside were like in 1955. That year the petroleum company made a 30-minute movie about the grand prix - this is back when the track was called the Francorchamps National Circuit, near the town of Spa, and a list of its important corners didn't include a mention of Eau Rouge - where it was doing the same thing it still does today: working on fuels and lubricants via its technical partnership with Ferrari.
To create the mood, journalists were invited to a vintage cinema where they mingled with Ferrari F1 drivers Fernando Alonso and Felipe Massa and other extras in period fifties gear, and watched a screening of 1955 Belgian Grand Prix. You can scroll down for a screening of your own, as well as the press release, minus the petits-fours and pinups.

LaFerrari XX coming early next year with F1 engine

With the embargo up on early reviews, the repetitively named Ferrari LaFerrari has become the supercar du jour. It has already been put through its paces by Top Gear and Evo. However, we know that Ferrari isn't done with development of its current halo model just yet. News continues to leak out about the even more hardcore LaFerrari XX track car.
Ferrari already confirmed directly to Autoblog that the XX is under development. There are even spy photos of it testing at the Nürburgring (pictured above). It reportedly clocked an astonishingly fast six-minute, 35-second lap at the historic track. The latest scuttlebutt about the track-focused supercar, according to Top Gear, is that it ditches standard car's hybrid 6.3-liter V12 engine with a combined output of 949 horsepower and 663 pound-feet of torque in favor of a Formula One-derived V6 turbo hybrid. That would be a huge change but would likely cut weight. The more insane LaFerrari could debut as soon as January or February of next year.
Ferrari says it's difficult to make the XX accelerate much quicker than a standard LaFerrari, but slick tires, revised suspension and aero changes should cut lap times. A version that doesn't have to worry about road car laws and just focuses on being fast could be truly mental.

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.
