Ferrari names new F1 car F138

Don't call it the F150. Ferrari has officially announced it will name its newest Formula One car the F138. The machine is the 59th car Ferrari has built to compete in F1, and it's also the last of the company's F1 efforts to rely on a high-strung V8 for propulsion. F1 rules have changed for next year, forcing competitors to use smaller cylinder counts to get around the track. Ferrari has already said it will use a 1.6-liter turbocharged V6 to do its dirty work. That moves brings an end to the eight-year reign the V8 enjoyed.
Ferrari isn't saying much more about the 2013 car, and the only image we have to go on at the moment is the logo you see above. Stay tuned for more information, and in the interim, be sure to check out the painfully brief press release below.

Weekly Recap: Aston Martin to add another sports car, new Lagonda sedan, EVs

Aston Martin will revamp and expand its lineup as part of a five-year plan laid out by the company's new executives. If it succeeds, the strategy will position Aston for growth as an independent automaker with a more stable future in its second century. Aston will replace all of the cars in its current lineup and add a fourth sports car to its stable. It currently has three: the DB9, Vanquish and Vantage. The unnamed sports car will be joined by a production version of the DBX concept – an all-wheel-drive electric car that treads near crossover territory – that was revealed at the Geneva Motor Show. Aston's electric strategy also includes a potential electric-powered Rapide. Eventually, Aston plans to build a new four-door Lagonda. Though Aston will diversify its portfolio and the range could expand to seven vehicles, it will limit production to around 7,000 units annually, said Aston Martin marketing and communications director Simon Sproule, who described the company's strategy in an interview with Autoblog. CEO Andy Palmer, who joined Aston last year from Infiniti, has also spoken recently about remaking the company for the future. EVs are a major part of Aston's future, Sproule stressed, because they allow the automaker to "balance" its portfolio. Aston is studying the feasibility of an electric Rapide and is working with an undisclosed engineering firm. It's likely to use a plug-in setup and would cost $200,000 to $250,000 or more. It could use either a rear-wheel or all-wheel-drive configuration. View 14 Photos "It's a study, but we're serious about it," Sproule said. He added for emphasis: "If not this, there will be an electric Aston Martin in the future." Aston has taken note of what Tesla has done with the brisk-driving Model S and decided that's the dynamic it wants for some of its own cars. Even though EVs don't emit the same sonorous note as a V12 – they're better than the alternative, Sproule said. "The sound of silence is much more preferable than the sound of a four-cylinder whining away under the hood of an Aston Martin," he said. Speaking of V12s, they're not going away. Aston will continue to make its own V12 engine, but will source its V8 from Mercedes-AMG (whose parent, Daimler, owns a small stake in Aston). While the V12 is sure to please the faithful, Aston admits EVs and the crossover-like DBX will rankle many. Sproule argues those are the moves that will keep Aston relevant.

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.
