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 to hack a Buick Regal with CarKnow

If you own an Apple iPhone or Android device, perhaps you've been tempted to jailbreak or root it. This process gives you access to the the software's code, and can be used to make minor or drastic changes to its operating system. CarKnow, a company in Boston, is working applying a similar concept to the automobile.
Translogic recently took a look inside CarKnow to see just how it can tweak the computers inside a car and what sort of things can be done. As our transportation tech sister site explains, CarKnow basically created a digital duplicate of their Buick Regal in the cloud, while harvesting data generated to create custom apps and infiltrate the deepest function of their test car.
And before you freak out about people maliciously taking over your car, CarKnow's founder, Josh Siegel, stresses that it isn't quite so easy as driving up alongside someone. Take a look at the full video below to see just what it's like to jailbreak a car.

2019 Buick Regal TourX sells better than expected, has brand's wealthiest buyers

Being a wagon fan in America is tough, since it seems everyone prefers the higher ride heights and SUV looks of crossovers. But today we have some good news for wagon fans via Buick. Apparently the 2019 Buick Regal TourX is popular with well-heeled buyers, and it's been selling quite a bit better than Buick expected. A representative from Buick revealed that Regal TourX buyers have the highest average income of any of the brand's products. He even noted that TourX buyers' average income is higher than the Buick Enclave Avenir, the extra-plush variant of the three-row crossover and the most expensive vehicle in Buick's lineup. To put the price difference into perspective, the most expensive Regal TourX starts at $35,995, while the Enclave Avenir starts at $54,695. Besides selling to people of some means, the Regal TourX has proven to be more popular than Buick expected. Buick's representative said that initial estimates were that the wagon would make up about 25% of sales, but it's actually making up about 40% right now. Buick has sold 3,408 Regals in total this year, so that means about 1,400 of them were TourX wagons. That number doesn't quite translate over all of 2018 since the TourX was released a little later and the supply was still ramping up through the year. As such sales were closer to 3,000 out of a little over 14,000 for the whole year, or somewhere above 20%. But the increased percentage from the model's release is still impressive. Granted, sales still favor crossovers. Buick's least popular crossover, the Envision, sold about twice as many units as all Regals last quarter. Yet, we count this as good news on the wagon front. Better still, the TourX's top rival, the Subaru Outback, has moved 76,000 units so far this year. Times may be tough for the wagon fan, but there are still some small wins to celebrate. UPDATE: The estimate of Regal TourX numbers for 2018 was higher than actual sales as the TourX was launched later than all Regal models, and the supply wasn't up to full steam for the whole year. The corrected number is now in the text. Related Video:
