Chevy ad compares Spark EV with Ferrari 458 Italia

Chevrolet's new commercial for the 2014 Spark EV emphasizes the little hatchback's performance over pretty much everything else, and it even goes as far as to compare it to a Ferrari 458 Italia. That's right, the electric bubble is pitched in the commercial as having a higher torque figure than the Ferrari - and it does, with a massive 400 pound-feet ready to be unleashed.
That doesn't translate into a quicker car, however, as the 458's V8 with 570 horsepower and not-exactly-quaint 398 lb-ft gives it a 0-60 time of 3.0 seconds compared to the Spark EV's 7.6-second run.
"We think the fun-to-drive element is an area for us to differentiate ourselves," Sam Basile, executive chief engineer for GM's global minicars and emerging-market vehicles, told Automotive News.

F1's Raikkonen to race for Sauber as Leclerc brings youth to Ferrari

Kimi Raikkonen will not be going out of Formula One at the top, or even with a top team. The announcement on Tuesday that the 2007 world champion is leaving Ferrari, the sport's oldest, most glamorous and successful team, at the end of the season was only to be expected. Less so was the subsequent revelation that the 38-year-old "Iceman" had agreed a two-year deal to continue with Ferrari-powered Sauber in a swap with that team's Monegasque rookie Charles Leclerc. That will close a circle at least, the Swiss team being the ones who gave Raikkonen his debut in 2001 despite the powers-that-be fearing he was too inexperienced. And it will keep the Finn racing on into his 40s. It will also please Formula One's owners, already facing the retirement of double world champion Fernando Alonso, by keeping one of the best known and most popular drivers on the starting grid. But the days when Raikkonen could hope for poles and wins, already scarce even at Ferrari where Sebastian Vettel is the main contender and team orders have been applied, are surely over now. Sauber was last in 2017 and is ninth of 10 teams now, even if the signs are more encouraging than they were, and there is a likelihood that Raikkonen will now be simply making up the numbers. The Finn will still relish racing with less media attention and more freedom, while for Ferrari there are also clear benefits. For the first time in four years, they now have a new benchmark for four-time champion Vettel and a (very) young driver who represents the future rather than the past. Vettel has outperformed Raikkonen consistently since the pairing started in 2015 with the German's move from Red Bull, and the Finn is already 62 points adrift this season with seven races remaining. Raikkonen has been more competitive this year, taking nine podium finishes and pole at Ferrari's home Italian Grand Prix with Formula One's fastest ever lap, but there are those who question whether Vettel is being pushed hard enough. Some even wonder just how quick the German really is. Ferrari will hope that 20-year-old Leclerc, unless told to adopt a subservient role, can apply a bit more pressure and help answer those questions. The gamble is that the youngster's relative inexperience could impact, in the short-term at least, Ferrari's constructors' championship hopes as he finds his way under considerable scrutiny.

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.
