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.

Second day of RM's Monterey auction continues the million dollar madness

RM Auctions' two-day event during the Monterey car week is pretty much a matter of appetizer and main course. Friday night's appetizer saw a trio of multi-million-dollar Ferraris, along with a pre-war Mercedes-Benz and a Jaguar D-Type. You can read all about those beauties right here. But as we said in that post, the action would really happen on Saturday night. The prices listed below include RM's ten-percent commission fee, and, as you'll see, the auction house did pretty well for itself.
We've already told you about the $27.5 million winning bid for the 1967 Ferrari 275 GTB/4 NART Spyder, with all the profits headed to charity. While there were more seven-figure winners on night two, the overall prices weren't quit as high as we saw on Friday night. The Ferrari F50 (pictured above) shown during the car's Geneva debut back in the 1990s and with only 1,100 miles on the clock took $1,677,500 (on a $1.25 to $1.6 million estimate). Another winner was a 1935 Hispano-Suiza K6 Cabriolet, which brought in $2,255,000 on a $1.5 to $2 million estimate. A 1974 McLaren M16C Indianapolis, the race winner of the 1974 Indy 500, brought home $3.52 million, essentially doubling its expected price of $1.25 to $1.75 million.
The night wasn't a success for everybody, though. The 1928 Mercedes-Benz 680S Torpedo Roadster, which took Best In Show at the 2012 Pebble Beach Concours d'Elegance failed to reach its $10-million expectations, selling for $8.25 million. That's not peanuts by any stretch, but a car that only goes for about 80 percent of its expected price isn't something to be enthusiastic about. A 1960 Maserati Tipo 61 Birdcage, which was expected to go for $3 to $4 million only took in $2,090,000.

Dan Gurney, legendary all-American racer, dies at 86

American racer Dan Gurney, who raced and won in Formula One, the 24 Hours of Le Mans, IndyCar and NASCAR in the 1960s and who started a trend by spraying champagne on the victory podium, died in California on Sunday. He was 86. The news was announced by his wife, Evi, and family in a statement. "With one last smile on his handsome face, Dan drove off into the unknown just before noon today, January 14, 2018," they said. "In deepest sorrow, with gratitude in our hearts for the love and joy you have given us during your time on this earth, we say, 'Godspeed.'" The family said Gurney, whose Formula One career spanned one of the most glamorous and dangerous periods of the sport's history from 1959 to 1970, had died of complications from pneumonia. He won seven IndyCar races, five in NASCAR and four in F1, placing second twice in the Indianapolis 500. He raced in multiple series concurrently throughout much of his career. He was the first of just three drivers to win races in four series — sports cars, Indycars, Formula One and NASCAR. The feat was later replicated by Mario Andretti and Joan Pablo Montoya. At the height of his popularity, in 1964, Car and Driver promoted the idea of electing him president. He retired from racing in 1970 but returned for a NASCAR race in 1980. Between 1965 and 2012, his All American Racers, which he founded with Carroll Shelby and Goodyear, built 158 race cars and is the only constructor to have built a winning F1 Grand Prix car, a winning Indy 500 car and a winning Sports Car.
