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's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

2014 GMC Sierra

Is the Best GMC Truck Ever Made Good Enough?
We've got a bright aluminum Airstream camper hitched to our rear bumper as we head up Southern California's coast because GMC says that 60 percent of all full-size pickup owners will use their trucks for towing.
Rather than forcing us to absorb its capabilities in a long-winded PowerPoint presentation, the automaker brought us to Los Angeles and handed us the keys to its all-new 2014 GMC Sierra 1500. After jumping behind the wheel of a 5.3-liter V8 model, we drove up the foggy Malibu coast (locals call the soggy early-summer weather "June Gloom") and made our way to the Camarillo Airport for a towing refresher. Once completed, a brand-new 23-foot Airstream was hitched to our aft end and we were pointed towards a campground just west of Santa Barbara.
