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.

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

GM recalling over 40,000 Chevy, Pontiac and Saturn models over fuel pump woes

The National Highway Traffic Safety Administration has issued a recall for a number of General Motors cars and crossovers bought or currently registered in the hot-climate states of Arkansas, Arizona, California, Nevada, Oklahoma and Texas. As many as 40,859 units consisting of the 2007 Chevrolet Equinox, Pontiac Torrent and Saturn Ion and the 2007-2009 Chevrolet Cobalt (shown) and its Pontiac G5 twin are being recalled for potential fuel leaks.
This recall is being issued due to potentially faulty fuel pump components that can crack and cause gasoline to leak from the return or supply ports and possibly cause a fire. NHTSA has not indicated how many fuel leaks or vehicle fires have been reported. As a fix, GM will replace the fuel pump modules on all affected vehicles free of charge. Since Pontiac and Saturn have been shuttered, owners will be able to go to another GM-brand dealership to have their vehicles repaired.
While the list of affected cars and crossovers varies by state and model year, if you own any of these models and live in Arizona, California, Florida, Nevada, Oklahoma or Texas, be sure to check the official notice below for more details.
