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 488 Special Series finally shown in official teaser video

It's been no secret that a hopped up version of the Ferrari 488 GTB is on the way. The car will follow the trend of previous models like the 458 Speciale and 430 Scuderia by reducing weight, boosting power and re-tuning the suspension and aero. Today, Ferrari itself finally gave us an official teaser on its Facebook page, and it looks like the leaked image from a few weeks back was correct. The timing of the video suggests we'll get the full breakdown in just a few weeks at the 2018 Geneva Motor Show. This is just a teaser, so all the video shows is a few very brief cuts and angles of the new car. We've taken a screenshot of the front end, and it's pretty obvious that it's the car we've been following in spy shots for months now. It's blurry, but — as seen in the linked image above — it looks like there are substantial changes to the front bumper. There also appears to be a few small aero tweeks on other places, but again it's difficult to discern. What's obvious is that the blue and white stripes have made another comeback. For a while, the car was being referred to as the 488 GTO. That no longer seems to be the case, though what it will be called is unclear. In the leaked presentation, Ferrari called the car the "New V8 Sport Special Series," though something a little more romantic is likely. Look for a twin-turbo V8 making upwards of 700 horsepower, up from the standard 488 GTB's 660 horsepower rating. Stay tuned for more news in the next few weeks. Related Video:

Ferrari 612 Scaglietti gets the shooting brake treatment

As much as we love shooting brakes, since they're basically two-door wagons, the world clearly isn't willing to buy them. Most remain concepts or just designs. But someone took up Dutch coachbuilder Vandenbrink on its design for a Ferrari 612 Scaglietti shooting brake. The company finished the car this year, and the results are impressive. The shooting brake's roof fits the existing roofline of the Ferrari well, and the car's signature wide haunches haven't been hidden. The hatchback also looks like Ferrari included it from the beginning, making the car look like a precursor to the FF and GTC4Lusso. The skylights in the roof are also fascinating, and they surely make the rear seats less claustrophobic. Vandenbrink's choice of the 612 Scaglietti is a good one, too, even if it was partly dictated by the fact the company penned this design over a decade ago. It's a classic grand touring car designed to be fast but comfortable. Its large size, particularly its prominent prow, suits a long-roof design, too. The one part we slightly question are the rear pillars, which even with some creases to break them up, look a bit large and out of place. This is currently the only example of the 612 shooting brake, but Vandenbrink is happy to build additional cars on request. The company says it will work with buyers every step of the way to make sure their example is customized exactly as they wish, from the paint to the equipment. Vandenbrink even suggests it could make one geared toward horse riding or falconry. There's no price for the vehicle, though, which is probably due to the fact that each one will be custom ordered and the cost will vary. And this is undoubtedly a car you can't afford if you have to ask the price. Vandenbrink is also happy to create one of a few other sports cars, such as a roadster version of the 599 GTB Fiorano. All you have to do is ask and bring tons of money.
