See what the Chevy C7 ZR1 may be benchmarked against

One of the greatest things every Corvette has had going for it, and also one of the most re-used arguments against it, is its price-to-performance equation - long before the Nissan GT-R became the de facto Porsche 911 comparator the Corvette spent decades as Exhibit A. Depending on which side of the argument you stressed, supporters crowed about how much performance you got for how (comparatively) little, detractors carped on how little you got everywhere else in the bargain.
It appears Chevrolet is working as hard as ever to render the argument meaningless. Spy shooters at KGP captured a convocation of European birds of prey leaving the General Motors test center, and aimed at benchmarking the C7 Corvette ZR1. The road train comprised of two C7 Corvette Stingrays, a 2013 Corvette ZR1, McLaren MP4-12C, Ferrari 458 Italia, Audi R8 V10 Spyder and Porsche 911 Carrera S and it was last seen heading down the same kinked-up back roads used to hone the Corvette Stingray.
The C7-series ZR1 and its possible 700 horsepower are still a ways off. If it really is being positioned to compete with the celestial exotica in the testing group, could it be the first Corvette to regularly be the first answer to the question "Cost no object, which would would you rather have?"

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.

FCA's European boss quits after losing out as Marchionne's replacement

MILAN — Fiat Chrysler's European boss has quit, adding to the problems facing new CEO Mike Manley, who must deliver on promises to boost production of SUVs and catch up with rivals in electric cars. Jeep division head Manley was named on Saturday to succeed Chief Executive Sergio Marchionne, one of the auto industry's most tenacious and respected leaders, who fell seriously ill after suffering complications following surgery. It emerged on Monday that Alfredo Altavilla, head of Fiat Chrysler's business in the Europe, Middle East Africa had resigned, according to a source with knowledge of the matter. He had been a rival for the top job along with Manley and Chief Financial Officer Richard Palmer. It's another complication to new CEO Manley's task of executing his predecessor's plan to keep the world's seventh-largest carmaker competitive in the absence of a merger. Marchionne had been due to step down next April, so the market reaction was limited on Monday. The shares initially fell more than 5 percent, but then pared some losses and were down 2.4 percent by 0930 GMT. "The downside may be modest, at least in the next 12 months. But long-term concerns will build — Marchionne ran FCA in a command and control style, with constant firefighting measures," said Bernstein analyst Max Warburton. Fiat Chrysler Automobiles (FCA) said British-born Manley would pursue the strategy that Marchionne outlined last month. FCA has pledged to increase production of sport utility vehicles and invest in electric and hybrid cars to double operating profit by 2022. It also unveiled bold targets for Jeep, which has become FCA's ticket to creating a high-margin brand with global appeal. Reviving struggling brands Analysts said that choosing Manley, 54, under whose watch Jeep's sales surged fourfold, sent a clear message that FCA was staying on course and would keep the Jeep brand at the heart of its growth plan. "Manley knows that his primary focus is on execution and that, already, he has a strategy into which his team has bought," said George Galliers, an analyst at Evercore ISI. "There is no reason the 2022 plan cannot be executed." Under Manley, the company is expected to sharpen its focus on revamping individual brands, including ailing Fiat in Europe, Chrysler in the United States and Alfa Romeo, which has yet to turn a profit despite multibillion-euro investments.
