Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

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.

Sunday Drive: Spying an automotive future of performance

I spy, with my little eye ... the future of the automotive world here in the United States. That pretty much sums up this week's Sunday Drive, in which we pull out the most popular stories on Autoblog of the previous week and try to draw some sort of conclusion as to what binds them all together. This week, it's spy shots, starting with one of the biggest and baddest muscle cars the world has ever seen: the Dodge Challenger Hellcat. The Hellish coupe gets a new hood for 2019 with dual scoops, but that's about the only meaningful change for the new model year. No matter. As long as it's packing 700-plus horsepower under those two hood scoops, all will be right with the world. Moving on, we take keep the performance angle but move it from the street to the dirt with a new version of the Chevy Colorado ZR2 that we think is probably called the Bison. We think it'll keep the high-tech suspension bits of the regular ZR2, but add expedition gear that may include a snorkel and a winch. Which, if true, is pretty dang cool. Keeping the truck theme is the 2019 GMC Sierra. There's nothing particularly noteworthy about the trim level in which the truck was spied, and that's what makes this specific example interesting. Base-model trucks almost never get much attention, but they sell in droves to workers who need an honest-to-goodness truck for work or play and don't care about bells, whistles, or massive chrome badges. And finally we have the 2018 Jeep Wrangler, which is on fire on the sales floor right now. But those are all V6-powered Wranglers flying off the showroom floor. Soon, a turbocharged four-cylinder engine option will become available, and now we know that it will return up to 23 miles per gallon in the city and 25 on the highway. That makes it the most fuel efficient Wrangler that Jeep has ever sold. As always, stay tuned to Autoblog this week for all the automotive news that's fit to publish. 2019 Dodge Challenger Hellcat with twin-scoop hood spied with no camouflage Chevy Colorado ZR2 Bison caught testing 2019 GMC Sierra 1500 spied in base trim level 2018 Jeep Wrangler four-cylinder fuel economy revealed Spy Photos Chevrolet Dodge GMC Jeep Truck Coupe SUV Off-Road Vehicles Performance dodge challenger srt hellcat sunday drive
