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 launches F14 T and yet another Formula One nose

Ferrari CEO Luca di Montezemolo said of the 2014 Formula One season, "It's time to win." This is the chassis that's meant to do it, and it is also Exhibit C in this wild, function-over-form F1 pre-season: the Ferrari F14 T. The low, trunk-like snout is another imagining of the year's regulations, after the probing proboscides found on the McLaren and in the image of the coming Williams. The public name of the chassis internally called 665 was chosen by Ferrari's social media fans, F14 T referring to the brand, the year and the turbocharged powerplant, not the McDonnell-Douglas F14 Tomcat.
The 60th Ferrari to contest an F1 season, it keeps the pull-rod front and rear suspensions of cars from the last two years but little else. The narrower front wing, having to package and cool the additional power unit equipment, reworking the rear wing and even moving to brake-by-wire has changed every other aspect of the car.
Fernando Alonso is hoping the F14 T will make the fifth time the charm; in his fifth year with the team, he wants to win the championship this year instead of coming in second again, just like Michael Schumacher won his first title with Ferrari after five years with the team. Our guess is that Kimi Räikkönen has no opinion on anything other than winning races and getting paid for it. A press release below offers a number of details, while the high-res gallery above to can help prepare you for what's coming.

Dubai police add Ferrari FF to keep Lambo company

Supercars are a sulky lot by nature. Leave them to their own devices and they'll quickly grow despondent. That's why so many owners have more than one exotic in the stable. The Dubai Police seem to have caught on to that fact, having just added a Ferrari FF to help keep the force's new Lamborghini Aventador company. The duo will patrol the city's more affluent regions to promote the area's image as a mecca for money.
Mission: accomplished.
Of course, the Dubai PD certainly isn't the first law enforcement agency to adopt flashy cruisers, and car gods willing, it won't be the last. There was the Nissan GT-R gussied up for police duty, as well as the Lamborghini Gallardo LP560-4 and the Mitsubishi Evo X, but we have to say the DPD certainly has the most lust-worthy stable at the moment.
