Ferrari 458 Speciale with aftermarket exhaust screams

Take an already amazing Ferrari 458 Speciale, add an aftermarket exhaust capable of shooting flames, and unleash the coupe in a tunnel to maximize its sonic glory. This video uses that simple formula, and the result sounds spectacular. According to the YouTube description, the Ferrari has a system from the company Frequency Intelligent Exhaust, and the new pipes make the high-revving V8 scream. The little jets of flame that come out the back only sweeten the experience. The video lets you hear these wonderful pipes while the 458 is stationary and on the move. From inside, the sound is surprisingly subdued when the driver doesn't have the throttle against the floor. It seems like you could actually cruise around without needing earplugs but still enjoy the superb noise when desired. Related Video:

Ferrari California T has a turbo V8 lurking under new nose [w/video]

The Ferrari California might technically be the Prancing Horse's entry-level model, but there is nothing basic about the latest upgrade for the California T. Showing its face to the public for the first time at the Geneva Motor Show, it is now propelled by a 3.9-liter, turbocharged V8 with 560 horsepower and 557 pound-feet of torque, which equates to an extra 70 hp and a 49 percent increase in torque over the previous engine.
The forced induction mill is enough to accelerate it to 62 miles per hour in 3.6 seconds. Also not that many Ferrari buyers are going to care, but the switch also means a 15 percent improvement in fuel economy. Oh, and based on the video preview below, it sounds pretty good, too.
While the new engine is certainly the headline grabber, there are other upgrades as well: a top that closes in 14 seconds, new steering box, improved magnetic dampers and an upgraded traction control system. Pininfarina also reshaped the nose to make it more look like Ferraris of the 1960s. This is seems to be the best looking and performing California yet.

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.
