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.

2019 Buick Regal GS Review | Because Buicks are allowed to be cool, too

Buick continues to try to convince everyone that its cars are cool, but we still haven't seen much evidence of this working. However, the 2019 Buick Regal GS is exactly the car that can help change people's minds about Buick in 2019. It has big red Brembos sitting inside superbly stylish wheels, bright red GS emblems everywhere, aggressive bodywork and some of the best sport seats in any car today. Buick truly made the GS look the part, and if you can get past the brand's Wal-Mart greeter personality, you're going to like the way it drives, too. The Regal GS is powered by GM's 3.6-liter V6 that makes a healthy 310 horsepower and 282 pound-feet of torque in this application. That gets mated to a nine-speed automatic transmission, which is the only option for the GS this time around. The previous generation Regal GS offered a six-speed manual, but we weren't missing it too badly here. With seemingly every car under the sun going the turbocharged route, it was refreshing to see GM use a big, naturally aspirated V6. Even stranger was that the Regal GS before this one was boosted, so you could say GM went the opposite direction of the industry trend. That previous GS made 270 horsepower and 295 pound-feet of torque from its turbocharged 2.0-liter four cylinder. So, while the V6 beats it by 40 horsepower, the old GS has it by 13 measly pound-feet of torque. Still, we dig the V6, because this car's power delivery is fantastic with a snarly but restrained exhaust note to go with. My largest quibble is taking off from a stop. The GS's throttle response is a little numb from the get-go, but put any revs to it and the car is ready to leap forward at any speed. This immediacy is increased when you put it into "GS" mode, which sharpens up the throttle, quickens shifts, stiffens the suspension, sends more power to the rear wheels and makes the steering heavier. The nine-speed is seamless and unobtrusive in traffic, but offers up surprisingly quick shifts when you're flat-out. Most of the time I end up ignoring the paddle shifters on cars with torque converter automatics, so I wasn't exactly missing them here. You can select the gears via the gear lever's slapstick function if you really want to, but it's hardly more engaging than just letting the car go at it. In GS mode it holds gears long enough and resists shifting out of the power band. During fall-attack on a backroad, it works smart and is on-par with the eight-speed in our Stinger GT long-termer.

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.
