GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."

Recharge Wrap-up: BMW cars to share i tech, Jordan to build solar EV charging network

Jordan is looking to promote EVs and build a solar charging network. The country is waiving import tariffs on electric cars, and is spending $120 million on solar chargers. It plans to build 3,000 charging stations, along with 30 MW of solar power. Some chargers will be powered by solar canopies, while others will get electricity from nearby solar farms. Jordan's solar plan should also help to lessen the amount of energy it needs to import from nearby countries. Read more from Navigant Research, or at Green Car Reports. BMW's mainstream cars will benefit from technology borrowed from the i3 and i8, according to BMW sales head Ian Robertson. In an interview with Automotive News, Robertson said that next-generation cars will use carbon fiber more extensively, and that more cars will get plug-in technology. He said that about half of i3 buyers opt for the range extender and added that it is incorrect to refer to a range-extended electric vehicle as a plug-in hybrid. Read more at Automotive News. The ethanol market should remain healthy despite falling oil prices. While cheap oil could drive down ethanol prices, demand still remains due to the federal biofuels standard. Additionally, ethanol producers may find it cheaper to ship their products as domestic oil production drops and railroad shipping opens up. Ethanol byproducts like distillers grains continue to sell, and foreign demand continues as other countries impose their own renewable fuel standards. Read more at Yahoo News.
