Ferrari pays tribute to Niki Lauda with one-off 458

Though Niki Lauda may today be chairman of the Mercedes F1 team, anyone who's seen Rush will know that he's inexorably tied to Ferrari. And it's that bond that Ferrari has celebrated with this special-edition 458 Italia.
Commissioned by an evidently dedicated fan through Maranello's Tailor Made program, this one-off 458 features a red paintjob with white roof and gold wheels. It's a livery that apes the cars Lauda drove for the Scuderia in the mid-70s, and carries through with tricolore racing stripes over the roof and throughout the red-stitched black leather interior.
Not the most subtle treatment we've seen, but then the Italia is hardly a subtle car to begin with. Lets just hope this particular example manages to steer clear of going up in flames as have so many 458s - and one notable 312 T2. Feel free to read more in the press release below.

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 458 M spotted, is there a turbo under there?

While it's still absolutely beautiful and a performance marvel (especially in Speciale trim), the Ferrari 458 Italia has to keep up with the rapidly evolving world in supercars if it wants to continue its success. Ferrari seems to know that it can't sit back and relax, because we're now seeing a disguised 458 testing for the second time.
Since we first saw it, rumor has emerged that it updated 458, reportedly called 458 M, may follow the lead of the recently revised California by using its turbocharged 3.9-liter V8 engine. The mill makes 553 horsepower and 557 pound-feet in that application, but those numbers clearly won't be enough for the Prancing Horse, because the standard 458 already makes more. Instead, Ferrari is expected to turn things up significantly to produce around 670hp, even more than the already gutsy Speciale.
Of course, to make the big change work, the 458 M must be able to ingest huge quantities of cool air to feed those turbos, and the camouflage on this test car is likely hiding the body changes to make that possible. Ferrari does a great job here of disguising things up front on this prototype, making it frustratingly hard to spot any changes.
