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 dominant at high-priced RM Auctions' Monterey event

Of the 21 multi-million-dollar lots sold over RM Auctions' two-day Monterey event, the top six were Ferraris while the top four were members of the vaunted 275 family. In total, 13 of the 21 seven- and eight-figure entries bore the yellow shield and prancing horse of the Scuderia.
Two cars in particular wowed bidders at the Monterey event - the exceptionally rare Ferrari 275 GTB/C Speciale and a 275 GTB/4 that was originally owned by Hollywood legend Steve McQueen.
The GTB/C Speciale was the first of a three-car run. Ferrari originally planned on campaigning the new range as a GT complement to its prototype entries at Le Mans, although squabbles with the FIA limited its racing career. Still, the extremely rare nature of this car means another example probably won't be coming up for auction for several years. Considering that, the GTB/C's selling price of $26.4 million does make a bit of sense.

If you need a carbon-fiber-bodied Ferrari F12, meet the Caballeria

Customizing a Ferrari, or any exotic for that matter, is a tricky process. Extreme looks and performance mean tuners and designers can't push the envelope much further without getting into tacky territory. But Spanish designers Bengala have toed the line with the new F12 Caballeria. Based on the F12berlinetta, obviously, Bengala claims the Caballeria draws inspiration from Ferrari's GT3 racers. We don't see it, but sure. The all-carbon-fiber body includes numerous smaller tweaks – check out the vents behind the doors and the new hood, for example – on top of much more drastic changes. The restyled fascia, larger intake, carbon-fiber splitter, and massive rear diffuser are the most obvious callbacks to Ferrari's road-going racers, while it looks like Bengala plucked certain new elements, like the three louver-style vents on top of the front fenders, from other Ferrari production cars. Those are the rear fender vents of the F12 TdF, for example. Bengala also swapped out the wheels for an Alpina-like fan-blade design. If you have money burning a hole in your pocket and dig the Caballeria's style, it might not look like a bad purchase. But be warned, unlike some other noted Ferrari modifiers, it doesn't sound like Bengala made any changes to the F12's 6.3-liter V12 engine. The company's press release didn't call out any mechanical changes, although that means there's still 730 ponies on tap – it's probably not a deal breaker. Like most of its projects, Bengala will only build 10 F12 Caballerias. It expects to wrap up production by the end of summer 2017. Related Video:
