2020 Chevy Corvette Stingray vs the world: How it compares on paper

The 2020 Chevy Corvette Stingray in its base form offers an astonishing amount of performance for the money. In fact, so impressive is the car's spec sheet that the Corvette kind of exists in two different competitive sets: one of cars priced similarly, and another with cars of similar performance and reputation. To get a feel for how it handles each of these segments, we've compiled specifications for those two sets of players. You can find the first set below, which looks at cars of roughly the same price point. Following that is a bit of analysis, and then there's a chart of cars with similar performance and reputation. And that chart will also have some analysis. Though final pricing for the Corvette hasn't been announced yet, we know the Corvette will start at less than $60,000. And as far as pricing goes, its closest competitor is the Porsche 718 Cayman, which also starts at just under $60,000. Both are mid-engined and rear-drive, but the Corvette offers an extra 195 horsepower and 190 pound-feet of torque. The Cayman does boast a curb weight of right around 3,000 pounds, so it weighs a few hundred pounds less than the Corvette, but it's likely not enough to make up for the power deficit. The Corvette's sub-3.0-second 0-60 time bears this out against the Cayman's best 4.5-second run. Impressively, though, the Cayman has more cargo space than the Corvette in a package that's nearly 10 inches shorter. The Cayman also still offers a manual option for those that prefer self-shifting. The 2020 Toyota Supra is on the cheap end of this sports car class, just crossing $50,000. It also boasts more power than the Cayman, though it's still down by 160 ponies and 105 pound-feet of torque to the C8. It's also about as roomy as the Corvette, despite being about the same size as the Cayman. Cargo space is a bit tighter. Its driving characteristics will likely differ, too as the Supra sits on a front-engine platform. It might even feel closer to a C7 Corvette in some ways. The other mid-engine entry in this price range is the 2019 Alfa Romeo 4C Spider. Its small 1.7-liter turbo inline-4 only makes 237 horsepower and 258 pound-feet of torque, but it's also far and away the lightest of this group at 2,487 pounds. That's roughly 1,000 pounds lighter than the Corvette. It isn't as fast as the Corvette in a straight line, but that lightness surely pays dividends in cornering and braking.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

The UAW's 'record contract' hinges on pensions, battery plants

DETROIT - After nearly four weeks of disruptive strikes and hard bargaining, the United Auto Workers and the Detroit Three automakers have edged closer to a deal that could offer record-setting wage gains for nearly 150,000 U.S. workers. General Motors, Ford Motor and Chrysler parent Stellantis have all agreed to raise base wages by between 20% and 23% over a four-year deal, according to union and company statements. Ford and Stellantis have agreed to reinstate cost-of-living adjustments, or COLA. The companies have offered to boost pay for temporary workers and give them a faster path to full-time, full-wage status. All three have proposed slashing the time it takes a new hire to get to the top UAW pay rate. The progress in contract talks follows the first-ever simultaneous strike by the UAW against Detroit's Big Three automakers. The union began the strike on Sept. 15 in hopes of forcing a better deal from each major automaker. But coming close to a deal is not the same thing as reaching a deal. Big obstacles remain on at least two major UAW demands: restoring the retirement security provided by pre-2007 defined benefit pension plans, and covering present and future joint- venture electric vehicle battery plants under the union's master contracts with the automakers. On retirement, none of the automakers has agreed to restore pre-2007 defined-benefit pension plans for workers hired after 2007. Doing so could force the automakers to again burden their balance sheets with multibillion-dollar liabilities. GM and the former Chrysler unloaded most of those liabilities in their 2009 bankruptcies. The union and automakers have explored an approach to providing more income security by offering annuities as an investment option in their company-sponsored 401(k) savings plans, people familiar with the discussions said. Stellantis referred to an annuity option as part of a more generous 401(k) proposal on Sept. 22. Annuities or similar instruments could give UAW retirees assurance of fixed, predictable payouts less dependent on stock market ups and downs, experts said. Recent changes in federal law have removed obstacles to including annuities as a feature of corporate 401(k) plans, said Olivia Mitchell, a professor at the University of Pennsylvania Wharton School and an expert on pensions and retirement. "Retirees want a way to be assured they won't run out of money," Mitchell said.
