Ferrari planning 458 Speciale Spider?

The Ferrari 458 comes from a long line of mid-engined V8 supercars to roll out of Maranello, from the 348 and F355 to the 360 and F430. Each has also bred a Spider version, and starting with the 360 Challenge Stradale (through the 430 Scuderia and 458 Speciale), a hardcore performance version. But combining the best attributes of Spider and performance model is relatively new territory for Ferrari, one which it attempted only with the limited-production Scuderia Spider 16M. And if the latest rumors are to be believed, it's about to go at it again.
Though we can't verify its sources, 4WheelsNews says it has double confirmation from within Ferrari that a 458 Speciale Spider is in the works. When reached for confirmation, Ferrari refused to comment, as it typically does on the prospect of new models yet to be announced. Given the precedent of the Scuderia Spider 16M, it would seem to make sense, but for the time being we'll have to chalk this one up as a rumor.
If it were built, the Ferrari 458 Scuderia Spider (or whatever it would ultimately be called) would take the best of the 458 Spider and 458 Speciale to pack the 600-horsepower version of Maranello's sweet-revving 4.5-liter V8 underneath a folding hardtop. The latter is something the 16M did not offer, but crucially, the new McLaren 650S Spider does. We'd also expect only a limited number to be produced at a suitable premium over the Spider's $257k MSRP and the Speciale's $288k sticker.

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.

At St. Moritz, the Ferraris and Bugattis are small wonders

The Little Car Company is once again taking to glitzy St. Moritz in the Alps to show off an array of scaled-down automotive classics that will include a Bugatti Baby II, Ferrari Testa Rossa J (for junior) in both base and Pacco Gara models, and an Aston Martin DB5 Junior. The elegant, electrified miniatures, all available for test drives, will be assembled at the upcoming International Concours of Elegance at St. Moritz this Friday and Saturday to entertain the rich and famous, and others perhaps not so well positioned. The Little Car Company is a U.K.-based firm that has re-created everything from a pint-sized Bugatti Type 35 to a life-sized dune buggy based on a Tamiya R/C kit from the 1980s. Their cars run on electric power. Other models are put on static display, and one of those at St. Moritz is to be its newly launched Bentley Blower Jnr. "A step into new territory for the brand," the company says, the Blower Jnr is an 85 percent scale electric version of the British manufacturer's legendary original, and is The Little Car Company’s first road-legal automobile. Said CEO Ben Hedley, "This year will be the third time that we have participated in this wonderful event, so it is only right that we bring even more unique pieces for guests to get behind the wheel of, but also that we bring something new for guests to look at: the Bentley Blower Jnr." Operating for about five years, the Little Car Company hand-builds licensed products in entertaining partnerships with some elite manufacturers. Its cars are aimed mainly at collectors but can be driven. Among its recent offerings, the Testa Rossa was launched in 2021 as a 3/4-scale replica of the legendary "red head,” powered by a 12kW battery and able to reach a top speed of 47 mph, Little Car Company planned to build only 299 examples of the Testa Rossa. One of them was on display at Harrods in London just before Christmas, priced at just about $100,000. A terrific gift, but youÂ’ll need a bigger tree.   Featured Gallery The Little Car Company at St Moritz Design/Style Aston Martin Bentley Bugatti Ferrari Electric
