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."

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."

GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:
