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 Modulo catches fire driving through Monaco

Accidents happen when you drive a car. The one-off Ferrari Modulo concept is not immune to such a fate, as the spaceship of a car recently caught on fire while out driving. In fact, it's certainly far more likely for an untested concept car to experience more issues than any kind of a production car that's gone through years of testing and development. This particular incident was documented on Twitter by Scuderia Cameron Glickenhaus. Jim Glickenhaus and his team recently bought the Modulo concept with the intention of making it road-worthy. The car was originally shown at the 1970 Turin Motor Show. We've since seen videos of it driving around, but this last drive went all sorts of wrong. This content is hosted by a third party.

He says that an unnamed firm they're no longer involved with designed the muffler that caught fire. Glickenhaus was prepared for such an occurrence (it does have a Ferrari engine in there after all). Jokes aside, the onboard fire suppression system did its job and extinguished the fire shortly after it began, saving the rest of the car. Unfortunately, it didn't act fast enough to save it from some pretty nasty damage to the rear of the body. Glickenhaus was driving the car through downtown Monaco when the fire began, so we can assume there was an excessive amount of heat building up in there. This content is hosted by a third party.

He tweeted a photo just an hour after the blaze showing the scarred Modulo charging up the mountains around Monaco. It's tough to trust a car right after a faulty design just caused it to catch fire, but who are we to doubt Glickenhaus? No plans for restoration were detailed yet, but we imagine the Glickenhaus team will have it looking like new as soon as it can. This content is hosted by a third party.

Porsche Taycan 4S, Ferrari Roma and a tuned Ford Ranger | Autoblog Podcast #624

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski and Senior Editor, Green, John Beltz Snyder to recap Earth Day 2020 coverage, including a first drive and range test of the 2020 Porsche Taycan 4S, Tesla and the state of the EV industry, and what we think are the best green cars of all time. Then they shift gears to talk about the Ranger pickup getting a tuning package from Ford, as well as their own dives through the Ferrari Roma configurator. They discuss the cars they've been driving — the 2020 VW Jetta and our long-term 2019 Subaru Forester. Lastly, they reach into the mailbag to help a listener buy a used car.
