GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

J.D. Power: Mini, Lexus again offer most satisfying sales experience

JD Power has released its annual Sales Satisfaction Index Study, and once again Mini and Lexus have taken top honors. Overall, buyers are more satisfied with the auto-buying sales experience than they were last year, with those surveyed reporting an average score of 664 points on a 1,000-point scale. That's up from 648 in 2011. Dealer satisfaction also increased by five points over last year as well.
All told, Lexus brought home an index score of 737, which was high enough to put it atop the luxury brands for the second year in a row. JD Power says Infiniti came in second in that category with a score of 728 and Cadillac rounded out the podium with it's rating of 725. Speaking of Infiniti, that brand saw the single largest jump in sales satisfaction of any brand on the survey, popping up 52 index points over 2011.
Among mass-market brands, Mini ranked highest with a score of 712, followed closely by Buick with 706 and GMC farther down the line with 683. You can check out the full press release below for more information.
