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.

GM expanding Lansing Lambda CUV plant

Considering that crossovers are a rapidly growing portion of the US auto market, it's not surprising to hear that General Motors is preparing to build even more of them. The company is investing $63 million to expand its Lansing Delta Township Assembly plant that builds Lambda platform CUVs like the Chevrolet Traverse, GMC Acadia and Buick Enclave.
According to GM, the expansion will add roughly 263,000 extra square feet of space to the plant. Of that, 181,000 square feet will be for an updated body shop with cutting-edge robots. There will also be 54,000 square feet of additional room in the paint shop and 28,000 square feet of more area for general assembly.
GM isn't saying as much, but there is the possibility that this extra space could allow for additional models produced at the factory. Cadillac reportedly dropped plans to build a three-row SUV on the Lambda platform earlier this year, however, dealers for the luxury brand were recently pitched the possibility of adding large and small CUVs, an ATS convertible or a sedan below the ATS.

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.
