Chevy says not to look at the 2019 Silverado's fuel economy rating

The 2019 Chevy Silverado is hitting dealerships soon, and one of the most notable changes for the new full-size pickup is the addition of a 2.7-liter turbocharged inline-four. The engine replaces the naturally-aspirated 4.3-liter V6 in volume consumer models like the Silverado LT and promises more power, less weight and — most importantly — better fuel economy. The thing is, the gains in efficiency haven't been as dramatic as some might have hoped, especially when stacked up against competitors from Ford and Ram. As Automotive News reports, GM's response is a little murky. First, let's talk numbers. We're pulling all figures from FuelEconomy.gov, the official U.S. government source for fuel ratings. Fuel economy numbers on trucks vary greatly based on a number of factors. Bed and cab configuration play a part, but so does a four-wheel-drive system. You also have to factor in tires, transmissions, rear-axle gearing, hybrid systems and cylinder deactivation. Things like that can make the difference between best- and worst-in-class. The EPA's website doesn't give enough information a lot of the time, so there's really no easy way to compare apples-to-apples. First, take a look at the ratings for the 2019 Silverado. A 2.7-liter model with two-wheel drive is rated 20 city, 23 highway and 21 combined. That's both better and worse than a two-wheel drive 2018 Silverado with the 4.3-liter V6 (18 city, 24 highway and 20 combined). The updated 2019 Silverado with a 4.3-liter V6 has yet to be rated. With less weight and a smaller engine, many hoped Chevy would make bigger gains. It's unusual to see any decrease in a fuel economy metric these days. GM says that it's not done tuning the new 2.7-liter engine, so fuel economy could theoretically increase. Expanding further, a V8-powered 2019 Silverado (17 city, 24 highway and 19 combined) actually gets better highway fuel economy than a turbocharged four-cylinder powered truck in certain configurations, even if the latter has a better overall average. But that's only with two-wheel drive, the 8-speed transmission and cylinder deactivation. A Silverado with the 5.3-liter V8 and a 6-speed automatic is rated at 15 city, 22 highway and 17 combined. The biggest issue with the Silverado 2.7-liter doesn't come from within GM itself but from Ford and Ram. GM cites the Ford F-150 with the 3.3-liter V6 and the Ram 1500 with the 3.6-liter V6 as the closest competitors to its new 2.7-liter inline-four.

Recharge Wrap-up: Chevy hits CO2 goal, eVgo and BMW build fast charging

Chevrolet has met its goal of preventing 8 million metric tons of CO2 emissions over the last five years. Through its community-based carbon reduction initiative, Chevy invested $40 million and took part in 38 different projects in 29 different states. The projects included supporting wind farms, powering a hospital with landfill gas, helping truckers reduce their idle time and helping create the ongoing #CleanEnergyU dialogue between students and clean energy leaders. In the end, Chevy retired all its carbon credits rather then spending them to offset its own emissions. Read more from Chevrolet. NRG eVgo and BMW are partnering to add DC Fast Combo charging to locations around the country. Over the next two years, the groups will bring hundreds of the 50-kW chargers to 25 cities, with 24 of those markets getting at least one installed by the end of 2015. "eVgo will add reliable DC Fast Combo capability to what is already America's largest DC Fast charging network," says eVgo President and CEO Arun Banskota. "This will be the fastest and most cost effective build out of a new network ever – thanks in large part to our existing infrastructure and committed retail host partners." Read more in the press release from eVgo. The EPA has settled with a Utah gasoline refiner over Clean Air Act violations. The HollyFrontier Corporation subsidiaries will pay $1.2 million for producing about 42 million gallons of gas that didn't adhere to Reid Vapor Pressure standards, resulting in 10 excess tons of volatile organic compound emissions. Its Salt Lake City refinery will also implement a program to offset past emissions. "This agreement will benefit public health by requiring retrofits of storage tanks at HollyFrontier facilities that will reduce volatile organic compound emissions and use next generation technology to verify these reductions," says Assistant Attorney General John Cruden. "This settlement shows that fuel refiners can and must meet the nation's standards for controlling the emissions that cause ground level ozone and serious health problems for Americans."

2016 Chevy Camaro performance figures released

If you want to make a car faster, there are two sure-fire ways to get the job done – add power and/or reduce weight. Chevy has done both for the 2016 Camaro, putting as much as 455 horsepower into its muscle coupe and shaving a few hundred pounds from every trim. That range-topping power comes courtesy of a 6.2-liter V8 engine, and it's enough grunt to push an automatic-equipped Camaro SS to 60 miles per hour in just 4.0 seconds flat (4.3 seconds with a manual) and down the quarter mile in 12.3 seconds at 116 mph (12.5 at 115 for the stick). Not coincidentally, those acceleration specs, at least on paper, put the V8-powered Camaro SS just above the Mustang GT on the muscle-car pecking order. When the road gets twisty, Chevy claims the Camaro SS can generate as much as .97 g on the skidpad. And, thanks in part to its Goodyear Eagle F1 summer tires, the SS can stop from 60 in as little as 117 feet. We look forward to finding out how nimble the new Camaro feels when compared to its primary competitors. <p>Your browser does not support iframes.</p> Moving down one notch to the 335-hp 3.6-liter V6, properly equipped 2016 Camaro coupes can hit 60 in as few as 5.1 seconds and cover the quarter in 13.5 at 103. Perhaps even more intriguingly, the 2.0-liter turbocharged four-cylinder and its 275 horsepower (the only configuration quicker with a manual transmission, incidentally) can propel the Camaro to 60 in 5.4 seconds and through the 'ol 1320 in 14 seconds flat. That's seriously quick, but buyers comparing the Camaro to the Mustang will find that the EcoBoost 2.3-liter is a bit more powerful (310 hp and 320 lb-ft) and quicker (5.1 seconds to 60). Chevy is making lots of noise about the efforts its engineers went through to shed weight from the 2016 Camaro, going so far as to shave down suspension bolts so that no thread went unthreaded. The weight-saving obsession pays off – base Camaro models are down 390 pounds while the SS model drops 223 pounds over the 2015. The 2016 Camaro SS boasts a power-to-weight ratio of 8.1 lbs per pony, a 14-percent improvement over the last-gen. Even though weight is down, chassis stiffness is said to be up by 28 percent over the fifth-gen Camaro coupe. Also of note: The Camaro is now lighter than the Mustang across the board when comparing like-to-like configuration levels. The 2016 Chevy Camaro starts at $26,695 (including $995 for destination).
