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.

Hacker jury rigs Amazon Echo into voice-controlled remote start

A lot of automakers have smartphone apps to start, lock, or unlock a connected car. Some automakers will even let you do that with a smartwatch. Then, there's YouTube user Jryanishere, who decided to use Amazon's chatty Echo voice-controlled, internet-connected information thingy. Yes, we said thingy, because we aren't really sure how else to describe the Echo. While the Echo system has received a hearty ad campaign – featuring Alec Baldwin asking Amazon's virtual assistant, Alexa, questions and ordering socks – we think this might be the first really useful thing we've seen it do. Using a MacBook, a Raspberry Pi, an Echo, an OBDLink plug-in, and his 4G LTE-equipped GMC, Jryanishere has basically made a voice-controlled remote-start system. Now, like so many voice-controlled things, this strikes us more of an extravagance than something that's functionally worthwhile. After all, the remote start on the a GMC keyfob isn't exactly rocket science. You can check out the Echo in action up top. Jryanishere gives a pretty thorough breakdown of how the setup works in the video above, but if you're at all into this sort of technological mischief, you'll want to watch (and check out the hilariously detailed blog explaining the job).

GMC Hummer EV SUV to be fully revealed during Final Four in April

GMC is going to use another large platform to reveal the next chapter in its Hummer story. The GMC Hummer EV SUV will officially be revealed on Saturday, April 3, at 5 p.m. ET during the Final Four. That’s the SUV, not the truck, which has already been revealed. YouÂ’ll be allowed to place a reservation for the SUV at the same time as itÂ’s unveiled during the basketball games. There are no further details about the SUV, but weÂ’ll point out that a decent preview of what the SUV will look like is already out and can be seen here. ItÂ’s going to look a whole lot like the pickup, but will of course be fully boxed in, as an SUV is. WeÂ’ll know more about what GMC has in store in just under a monthÂ’s time.  In addition to the news about the impending SUV, GMC released video footage of the pickup version undergoing winter testing in MichiganÂ’s snowy Upper Peninsula. You can see the video below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. GM says that itÂ’s using this region to dial in and calibrate the truckÂ’s all-wheel-drive torque distribution, traction control system and stability control. Testing is conducted on snow, ice, and steep and split-friction grades. ThatÂ’s all GM is letting us in on for now, but at least we have the second version of the electric Hummer in our scopes now and will be eagerly anticipating its reveal.
