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.

Sebastian Vettel captures Belgian Grand Prix

SPA-FRANCORCHAMPS, Belgium – Ferrari's Sebastian Vettel sped away from first corner carnage to celebrate a commanding Belgian Grand Prix victory on Sunday and trim Lewis Hamilton's Formula One lead to 17 points with eight races remaining. Hamilton, last year's winner in Belgium, started from pole position but finished second for Mercedes while Red Bull's Max Verstappen gave his army of Dutch fans something to cheer with third place. In the battle of four-times world champions, Hamilton now has 231 points to Vettel's 214. "I had a great start, I'm not sure Lewis saw me as he pushed me to the left in the first lap, but after last year I ended up short, and this year it was the other way around," said Vettel of his decisive pass on Hamilton. "As soon as I was ahead I relaxed. I had a good restart after the safety car, and after that it was a very smooth race," he added. The start provided most of the afternoon's excitement, with Fernando Alonso's McLaren flying over Charles Leclerc's Sauber at the La Source hairpin after being rammed by Renault's Nico Hulkenberg. All three retired as the safety car was deployed for four laps but Leclerc had reason to thank the 'halo' head protection system -- introduced this season -- for allowing him to step away unscathed. Television close-up images after the race showed the structure heavily marked by the impact. "The Halo was a very good thing to have today. I think for him, it helped," commented Spaniard Alonso, who will be leaving Formula One at the end of the season. Ferrari's Kimi Raikkonen, a four times winner in Belgium, and Red Bull's Daniel Ricciardo also collided at the start and retired after pitting, the Finn having to wait for his 100th career podium. At the front, Vettel swiftly seized the lead from Hamilton down the Kemmel straight on the opening lap and never looked back, taking the checkered flag 11.0 seconds clear of Hamilton. "He drove past me like I wasn't even there on the straight," said Hamilton, who was quick to shake his rival's hand and offer congratulations. "They have got a few trick things going on in the car," he added. "I did what I could, we did what we could so we have to keep working." It was the German's fifth win of the campaign, matching his British rival, and 52nd of his career -- one more than the great four times champion Alain Prost managed. Hamilton's team mate Valtteri Bottas finished fourth, and set the fastest lap, after starting 17th.

Meet the man that discovered and restored the oldest existing Porsche

Luciano Rupolo is an absolutely fascinating gentleman. He was born in France but spent nearly his entire life in Italy as an auto mechanic running his own shop. His grandfather and father instilled a love of sports cars in him that he carried on by historic racing in Italy for decades. He saw his life-long automotive passion repaid when he found and restored the car that might have been the first Porsche registered for the road.
You can spot in his garage a split-window Corvette, Ferrari 250 GTE and other exotics, but Rupolo's most interesting automotive story concerns his Iso Grifo Competizione (pictured above). The sports coupe was found in the Canary Islands as little more than a shell, but Rupolo got help from a prestigious source for its restoration. The result is a motoring masterpiece.
Rupolo is a fantastic storyteller with a captivating, tale to tell. Settle in, scroll down and watch the bittersweet documentary about his life with one of the first Porsches.
