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.

Chief justice invokes 'Ferris Bueller' Ferrari in Supreme Court car case

WASHINGTON — U.S. Supreme Court justices on Tuesday wrestled with the scope of police authority to search vehicles without warrants, with Chief Justice John Roberts referencing the shiny red Ferrari taken for a joyride in the 1986 comedy film "Ferris Bueller's Day Off" to make a serious legal point. The justices heard arguments in two cases in which convicted defendants are seeking to have key evidence against them thrown out because it was obtained by police officers through vehicle searches conducted without a court-issued warrant. One case involved a stolen motorcycle that was covered by a tarpaulin and parked on private property next to a house in Charlottesville, Virginia. The other involved a rental car stopped by police in Pennsylvania — driven by a man who was not named on the agreement with the rental agency — in which heroin was found. At issue is whether police in the two cases violated the U.S. Constitution's Fourth Amendment, which protects against unreasonable searches and seizures. In the motorcycle case, Roberts and other justices seemed concerned about issuing a broad ruling in favor of law enforcement that would let police officers not just inspect the immediate area outside a property without a warrant but also potentially inside a house if a vehicle is located there. Under the Fourth Amendment, police need a warrant to search a house unless there is an emergency situation. In the case of convicted defendant Ryan Collins, the motorcycle was a few feet from the house. In "Ferris Bueller's Day Off" starring Matthew Broderick, three teenagers skip school and take a ride in a red 1963 Ferrari Modena Spyder California that was parked inside a showroom-type garage apparently attached to a house. After mentioning the film's car, Roberts asked Trevor Cox, the state of Virginia's lawyer who was defending the police search, whether he was arguing that police "can just go in" to a house without a warrant because a car is "mobile and they got it in there somehow (so) they can get it out." Roberts also mentioned comedian Jay Leno, known for storing a large collection of cars. Other justices voiced similar concerns, including Neil Gorsuch, who seemed troubled about police officers being able to search garages and other outbuildings without a warrant. "Not many people live in their garage. Some people do, some people do, and in barns, but usually they're reserved for cars and for animals.

The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.
Or you can go straight to the high-res galleries above.
