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.

Chevy Malibu rolls over 10 million on the odo

On the cusp on the introduction of the latest model, the Chevrolet Malibu is celebrating a major milestone with 10 million of them now on the road since the car's introduction 51 years ago. While not quite enough to rank among the best-selling vehicles of all time, the feat is impressive considering the name took over a decade off from the Chevy lineup in the '80s and '90s. The Malibu started life in 1964 as the top trim on Chevy's new, midsize model, which also included the 300 and Chevelle. Offered in a plethora of body styles, including a wagon and convertible, the Bowtie brand moved over 370,000 of them in the first year. By 1969, sales reached more than 503,000. However, the market for rear-wheel drive sedans eventually softened in the US, and the Malibu name was dropped in 1983. The moniker returned in front-wheel-drive form in 1997 and has been a part of the lineup again ever since. These days, the Malibu is obviously only available as a four-door, but the model is more efficient than ever. The larger, lighter 2016 example can get up to 37 miles per gallon highway with its 1.5-liter turbocharged four-cylinder or 47 mpg combined when the hybrid goes on sale next year. You can get a great look at the Malibu's changes from the original until now in the gallery above.

Chevrolet celebrated the sales achievement today for the global sedan in the United States, China and Korea, which collectively account for more than 90 percent of sales. The Malibu is sold in more than 25 markets around the world. "The Chevy Malibu joins an exclusive club of vehicles that have achieved this extraordinary milestone and we acknowledge it today by honoring the common thread linking every one produced: The customer," said Alan Batey, president, global Chevrolet. "Some people are buying their very first Malibu today and others may have driven a Malibu from a different generation as their first car. It is a car that has resonated with customers for more than half a century." Chevrolet's interaction with customers has evolved since the Malibu was introduced in 1964. Back then, an owner's manual and a personal relationship with the dealer defined conventional customer service.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
