2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.

GM seeks national mandate for zero-emissions cars

DETROIT — General Motors says it will ask the federal government for one national gas mileage standard, including a requirement that a percentage of auto companies' sales be zero-emissions vehicles. Mark Reuss, GM's executive vice president of product development, said the company will propose that a certain percentage of nationwide sales be made up of vehicles that run on electricity or hydrogen fuel cells. GM says a nationwide program modeled on such a requirement in California could result in 7 million electric vehicles, or EVs, on U.S. roads by 2030. California wants 15.4 percent of vehicle sales by 2025 to be EVs or other zero emission vehicles. Nine other states, including Maryland, Massachusetts, New Jersey and New York, have adopted those requirements. In January, California Governor Jerry Brown set a target of 5 million zero-emission vehicles in California by 2030. The Trump administration criticizes California's ZEV mandate, saying it requires automakers to spend tens of billions of dollars developing vehicles that most consumers do not want, only to sell them at a loss. Reuss told reporters that governments and industries in Asia and Europe "are working together to enact policies now to hasten the shift to an all-electric future. It's very simple: America has the opportunity to lead in the technologies of the future." A national mandate also would create jobs and reduce fuel consumption, CO2 emissions and "make EVs more affordable," Reuss added. GM, the nation's largest automaker, will spell out the request Friday in written comments on a Trump administration proposal to roll back Obama-era fuel economy and emissions standards, freezing them at 2020 levels instead of gradually making them tougher. Under a regulation finalized by the Environmental Protection Agency at the end of the Obama administration, the fleet of new automobiles would have to get 36 miles per gallon by 2025, 10 mpg higher than the current requirement. But the Trump administration's preferred plan is to freeze the standards starting in 2021. Administration officials say waiving the tougher fuel efficiency requirements would make vehicles more affordable, which would get safer cars into consumer hands more quickly. GM on Thursday said it doesn't support the freeze, but wants flexibility to deal with consumers' shift from cars to less-efficient SUVs and trucks.

GM, Pilot will build EVgo fast chargers at 500 truck stops across U.S.

All of our maps showing electric vehicle charging stations across the U.S. are going to need an update. Today, General Motors, Pilot and EVgo announced plans to work together on a nationwide DC fast charging network. The plan calls for 2,000 charging stalls that can deliver up to 350 kW to be installed at up to 500 Pilot and Flying J travel centers in the U.S. The goal is to have DC fast chargers available in 50-mile intervals across the country. The new charging stations will feature GM's "Ultium Charge 360" branding and "Pilot Flying J" logos but will not be limited to drivers of GM EVs. The plugs will use CCS connectors and be available to anyone. GM EV owners can take advantage of benefits, including the ability to make exclusive reservations, get discounts on charging costs and streamline the charging process with Plug and Charge and in-vehicle apps that can provide real-time charger availability. The first installation phase will take place in 2023, and "the bulk of the installations" should be completed by 2025, EVgo CEO Kathy Zoi said during a conference call with reporters announcing the plan. "We're gonna get going immediately and commence all of that engineering and planning stuff," she said. "We've got a pretty orderly plan." Pilot CEO Shameek Konar said the company expects the new EV charging stations to coexist with the current fuel infrastructure. "An average Pilot Flying J location is about 10 acres," Konar said. "This will be in addition to all of our gas pumps. The way I think about it is, this is a new source of energy that is going to coexist with gas for quite some time. We can debate how long, but we need to serve both groups of customers." Installing DC fast chargers at hundreds of Pilot's travel centers — aka truck stops — means there should be food, drinks, restrooms, WiFi and even showers available while you wait for an EV to charge. Pilot recently announced its “New Horizons” plan that will invest $1 billion in upgrading Pilot travel centers with more premium amenities, including expanded seating and lounge areas. While the exact amount of time it will take to charge an EV using these new stations will vary on the EV and its current state of charge, most EVs can refill from a low state of charge to around 80 percent in 20-30 minutes on a fast charger. The new stations are future-proofed to deliver up to 350 kW, a charge rate that few EVs today can handle.
