GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

How two-state Chevy Spark EV outsold 50-state Volt last month

Is it really just about price? Last month, the Chevy Spark EV got a sizable price drop of $1,500 alongside a lowered lease price of $139 a month (down from $199). Those numbers, particularly that cheap lease, had a tremendous impact on how many all-electric Sparks GM sold last month. There were 920 Spark EVs sold in April, and the Spark EV is available in only two states: California and Oregon. Sales will start in Maryland in the third quarter of 2015, but there are no pre-orders taking place there, so all 920 were West Coast sales. To be more precise, there were about 864 Spark EV leases signed last month, since 94 percent of those 920 sales were retail leases. As Annalisa Bluhm from Chevrolet communications told AutoblogGreen, that level was, "simply insane." "In those states which offer Spark EV, you can get a 1LT Spark EV for less than a 1LT Spark, with more features" Bluhm said. "Factor in that you will save approximately $82 per month by abstaining from gas, and it's easy to see why people went crazy for the Spark." Let's put 920 into perspective. For one thing, it's crazy up from the 151 Spark EVs sold in March 2015 and the 97 sold in April 2014. It's also almost as many as GM sold all last year, and way more than two years ago. The General sold 653 Spark EVs in 2013 and 1,146 in 2014. To throw in a comparison with GM's longstanding plug-in champion, the aging Volt, the Spark EV came out ahead in the monthly tally for the first time ever. In April, the Volt sold 905 units. The plug-in hybrid's best-ever sales month was August 2013, when it sold 3,351 units. Counting all models and powertrains, Chevy sold 3,743 Sparks in April. So, does this success mean that Chevy is looking to bring the Spark EV to more markets? Bluhm said that GM is considering other states and is always looking at the business case, but has "nothing to announce yet."

GM recalling over 243,000 crossovers over possible seat belt defect

The summer of 2010's recall hit parade continues unabated today, with General Motors having just announced that it is asking 243,403 owners of its 2009-2010 Lambda crossovers to bring their three-row haulers in for inspection. The culprit? Second-row seat belts in select Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook CUVs have "failed to perform properly in a crash."
According to GM, a second-row seat-side trim piece is to blame, as it can impede the upward rotation of the buckle after the seat is folded flat. As a result, if the buckle makes contact with the seat frame, cosmetic damage can occur, potentially requiring additional force to operate the buckle properly. So far, no great shakes, but in the process of applying that additional force, the occupant may push the buckle cover down to the strap, potentially revealing and depressing the red release button. As a result of this, the belt may not latch, or in certain cases, it may actually appear to be latched when, in fact, it isn't.
