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.

Motor Trend hits Laguna Seca with Ferrari F12, Chevy Corvette, Porsche 911

According to the crew at Motor Trend, we should think of the video below "as an addendum to Best Driver's Car," a test the magazine put together that elevated the 2013 Porsche 911 Carrera 4S above all others in the category of driving joy. It seems the brand-new 2014 Chevy Corvette Stingray wasn't able to take part in the magazine's official test, and neither was the Ferrari F12 Berlinetta.
And so Motor Trend did the only logical thing: It procured both the 'Vette and Prancing Horse as soon as it could, and put them both on track with the Driver's Car-winning 911. Of course, these cars don't actually compete against each other - the Ferrari offers up 731 horsepower and wears an asking price of $434,144 as tested, which means you could buy four loaded Corvettes for the price of one F12, and still have money left for a garage to store them in - but that's not the point of this particular test.
The point of this test isn't to listen to the beautiful sounds coming from the Porsche's flat-six-cylinder, the Corvette's pushrod V8 or the Ferrari's luscious V12, either, but the video below is worth watching for those three reasons alone. You know what to do.

Scarbo Performance SVF1 First Drive Review | A hot-rodder's take on vintage F1

THERMAL, Calif. — Some turn their nose to the sky as soon as they hear the term, "replica." They only care for "originals," cars that are inevitably destined to collect dust in someone's impeccably clean garage, preserved for posterity, and never revved in anger or given the beans in fear of fouling up an "investment." Joe Scarbo thinks this "mere existence" is a boring one, that cars are meant to be driven hard – period. That's the outlook that spurned him to create the SVF1, an ass-kickin' track weapon so good, and so demanding, our body quit well before we wanted to hand back the keys. Once you realize what the Scarbo Performance SVF1 actually is, you'll get it. The open-wheeled, open-cockpit retro-racer is modeled after a 1967 Ferrari F312 Formula One car, and many, justifiably, consider its sultry, minimalist lines to be among the prettiest F1 designs. However, the guts under its beautifully hand-beaten aluminum exterior are more SoCal hot-rodder than devout Tifosi replica. Made even clearer that this track beast resides in the former is what powers it; a Red, White, and Blue-blooded GM-sourced, 430-horsepower LS1 V8. You can't get much more American than that. Our date with the SVF1 occurred at The Thermal Club near Palm Springs, an automotive oasis plopped squarely in the middle of an agricultural hub. The freshly finished facility is just a few hours outside of Los Angeles, but unlike the better-known Willow Springs, the track surface here is absolutely pristine, on top of which there was a fine mist of sand, a condition which kept both us and the SVF1 on our tiptoes. To provide the perfect soundtrack for our track adventure, Scarbo married the LS1's fly-by-wire throttle system with eight velocity stacks, providing an otherworldly induction yowl. This is punctuated by a guttural exhaust featuring an eight-into-one collector with a three-inch exit. Upon startup, the SVF1 is sends shivers through your body, and like chain lightning it propagates through the bodies of anyone within 60 feet. Grunt and stamina are required to shift the transaxle 5-speed manual transmission from a 986-generation Porsche Boxster mated up to the LS1. No flappy paddles or dual-clutches here. You get into the SVF1 by placing your feet onto the softly padded seat and sliding your butt in-between its fuel tank, which straddle your hips and posterior. Clip into the five-point harness and you're eyeball level with the truly massive Avon race-spec slicks.
