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.

Chevy Silverado, GMC Sierra 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.
While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity - besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan. Scroll down for the official press releases from Chevrolet and GMC.

NHTSA opens safety investigations into Toyota, GM and Honda crossovers

The National Highway Traffic Safety Administration is evidently keeping itself very busy these days, as the federal agency has just announced it is launching or renewing investigations into Toyota, Honda and General Motors crossovers.
2006-2008 model year Toyota RAV4 crossovers are under review for allegations of rear tie-rod rust which can result in failure. NHTSA also said it is probing some 35 complaints about 2005 Honda Pilot models with inappropriate activation of the vehicles' stability control system. The alleged malfunction can cause the vehicles to slow down or stop in bad unsafe situations. At the moment, NHTSA is reviewing a petition regarding the Pilot issue, a move that will determine whether it needs to open a full-blown investigation.
In addition, Saturn Outlook and GMC Acadia three-row crossovers built in 2007-2009 are getting looked at for "loss of low beam headlamp" function. One complainant said the wiring in his Outlook overheated and melted. NHTSA says it has received 415 complaints about the problem and a GM spokesman confirmed that the automaker already started a "Customer Satisfaction Program" in December to address the issue.
