2014 Chevy Cruze Diesel destined for Chicago debut

It's been a little over a year and a half since General Motors first confirmed plans to offer a diesel-powered Chevrolet Cruze here in the United States, and we've now learned that the oil-burning compact will debut under the lights of the Chicago Auto Show in February. According to GM Authority, the Cruze Eco-D will be introduced as part of the entire 2014 model year Cruze range, set to go on sale in the second quarter of this year.
Earlier reports have indicated that the diesel Cruze will be able to achieve fuel economy numbers in the range of 50 miles per gallon. For comparison, the similarly sized Volkswagen Jetta TDI is rated at 30/42 mpg city/highway, but as we found out in our long-term test of the 2011 model, hitting 50 mpg was a piece of cake.
Official specifications will be released at the time of the 2014 Cruze's unveiling, though reports have stated that the sedan will be powered by a reworked version of the 2.0-liter turbo-diesel inline-four found in the Holden Cruze CDX overseas. In that application, the four-pot oil-burner produces 160 horsepower and 265 pound-feet of torque - increases of 20 hp and 29 lb-ft over the 2.0-liter engine used in VW's Jetta TDI.

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.

Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.
