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.

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.

Scuderia Corsa ready to recapture glory at Le Mans

There's nothing else in this world like endurance car racing. Be it a relatively short race like the 6 Hours of Nurburgring or 24-hour endeavors like Le Mans or Daytona, drivers and cars alike are put through long and grueling racing that either ends in triumph or heartbreak. At this year's Detroit Grand Prix, we had a chance to sit down with Scuderia Corsa drivers Alessandro Balzan and Christina Nielsen just hours before they left for France to participate in first practice for the 24 Hours of Le Mans. Scuderia Corsa competes in the IMSA WeatherTech Sportscar Championship team in the GT Daytona class. This is the second year Balzan and Nielsen have partnered, and the relationship has been fruitful. The pair won the class championship in 2016 and are currently sitting in second for 2017. Despite being in the sport longer, this will be Balzan's first attempt at Le Mans. The pair will be joined by American Bret Curtis in the race, usually racing against Balzan and Nielsen behind the wheel of a BMW. "There's a lot to prepare for with this race," Balzan said. "Christina raced there last year, so she's helping me prepare. It's not like any other race, even something like Daytona. There's a lot of preparation that goes into this race." Everything from food intake to sleep schedules has to be adjusted and set appropriately. There's 24 hours of on-track action bookended by pre-race prep and a post-race cool down. Your body and mind must adjust accordingly, and it's not as simple as drinking a few cups of coffee and munching on an energy bar. Scuderia Corsa is the defending class champion at Le Mans, though not with Nielsen behind the wheel. The team is backed by Ferrari and competes with 488 GT3s, a stripped out, lightweight, race-only version of the 488 GTB. The cars share a version the 3.9-liter turbocharged V8, but the rest of the car has been extensively modified, bearing little resemblance beyond styling. "The cars don't share much with the regular car," Balzan said. The interior is all removed and the suspension and aero are all different. It looks similar, but it's really changed. It drives like a totally different car." That's par for the course with GT cars. While they might share more in common with road cars than something like the Porsche 919 Hybrid prototype, the world of race cars and production cars are far removed. That said, Balzan and Nielsen both enjoy the road car correlation.
