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.

1962 Ferrari 250 GTO hits record $38 million sale at Bonhams' Monterey auction

This weekend's Pebble Beach Concours d'Elegrance brings together some of the rarest and most expensive automobiles in the world onto a tiny peninsula in California jutting out into the Pacific Ocean. But this year, there has been one vehicle on everyone's lips - a 1962 Ferrari 250 GTO. Bonhams put up this incredibly rare Prancing Horse at no reserve for its auction at the Quail Lodge, meaning it could have sold for just a dollar. It didn't though, this ex-Jo Schlesser owned Ferrari sold for a staggering $38.115 million. That makes it the most expensive car ever sold at auction, beating out Bonhams' sale of a Mercedes W196R last year for $29.65 million.
Ferrari only built 39 of these racers, and they have been million-dollar cars for years. One reportedly sold privately for $52 million last year, and one built for Stirling Moss went for $35 million privately in 2012.
While the spectacle of seeing a 250 GTO drive across the auction block with no reserve and then set a record price was certainly amazing, it wasn't the only rare Ferrari up for sale during the evening. Bonhams also handpicked some of the most collectible Ferraris in the world and brought them to the stage. The ten cars included a 1962 250 GT Short-Wheelbase Speciale Aerodinamica that went for $6.875 million, a 1953 250 Mille Miglia Berlinetta driven to racing victory by Phil Hill for $7.26 million and even a 1978 312 T3 Formula One car for $2.31 million. All told, the group of them sold for $65.945 million.

This '61 Ferrari 250 GT SWB could be yours for eight figures

The 250 GT SWB Berlinetta ranks among the most desirable of Ferraris, and this one has been under the same ownership for the last 47 years. Now it's coming up for auction. Chassis No. 2917GT served as the Prancing Horse marque's centerpiece at the 1961 Paris Motor Show, where it was displayed in light blue. Its first owner, however, only owned black cars, so he had it repainted. It changed hands a few times over the years, and was repainted in classic red somewhere along the way. That's the color it remains today. Its current owner is described as a well-regarded collector living in the Brittany region of France and has reportedly taken exceptional care of it, driving it regularly and bringing in the best mechanics to service it. But after nearly half a century in his care, he's letting it go. Artcurial will be handling its sale during the Le Mans Classic on July 9. We're waiting on word regarding how much the auction house expects it to sell for, but the records at Sports Car Market have similar examples selling in the past couple of years for upwards of $10 million. Given the apparent condition of this particular specimen, we don't doubt that it'll fetch top dollar. THE EX-PARIS MOTOR SHOW 1961 FERRARI 250 GT SWB BERLINETTA IN SAME OWNERSHIP FOR 47 YEARS – LE MANS CLASSIC, SALE 9 JULY 2016 – Paris – Artcurial Motorcars has raised its international profile in recent years by offering some of the world's rarest and most valuable cars at auction. The top ten most expensive cars ever to sell at auction include two cars from each of Artcurial Motorcars' last two Retromobile sales: the ex-Bardinon 1957 Ferrari 335 S Spider Scaglietti that sold on 5 February 2016 for 32.1Mˆ / 35.7M$ – a world record price (in ˆ and GBP) for a car sold at auction – and the 1961 Ferrari 250 GT SWB California Spider from the Baillon Collection that fetched ˆ16.3M / 18.5M on 6 February 2015. Artcurial Motorcars is also known for consigning important cars that are new to the market, a key feature of the star car in the next sale at Le Mans Classic on 9 July. The 1961 Ferrari 250 GT SWB Berlinetta #2917GT has been in the hands of the present owner some 47 years, and has had just five owners from new. This remarkable car was displayed new at the 1961 Paris Motor Show, presented in a light blue Azzuro.
