2021 Cadillac Escalade, GMC Yukon, Chevy Suburban/Tahoe recalled for stall risk

General Motors is recalling just shy of 15,000 2021 Cadillac Escalade & Escalade ESVs, Chevrolet Suburbans and Tahoes, GMC Yukons and Yukon XLs that were shipped with fuel pumps that were built with a batch of what may be faulty electronic control modules. A pump with a bad module can result in intermittent function, resulting in drivability issues and potential stalls. No serious incidents or injuries have been associated with the issue.  GM says it discovered the issue after analyzing early recall data for the 2021 model SUVs and discovering an unusually high failure rate for fuel pumps manufactured by a single supplier – Vitesco. The company was able to identify the batch and initiate a recall campaign targeting just those vehicles.  "After reviewing the field data, GM determined there were 617 potentially relevant complaints, which were received between April 15, 2020 and August 24, 2021," the company's recall report said. "229 of these complaints reported a stall while standing or moving. No accidents or injuries associated with this condition were found." Any SUVs built with pumps from that batch but not yet sold are being held at dealers for replacement parts. It may take some time for GM to source replacements due to the ongoing electronic parts shortages.  "We are working with the supplier to obtain the required parts as quickly as possible," GM said in its notice to dealers. "When sufficient quantity of parts are available, the recall bulletin will be released and dealers can begin repairing vehicles."

The cars and trucks of 'Transformers: Rise of the Beasts'

The latest spectacle in the Transformers franchise is about to hit the theaters. The final trailer was released, giving us peeks at what appears to be a pretty boilerplate story about the end of the world. There's some kind of ancient interplanetary war brewing and it's up to some teenagers to sort it out with the help of their robot buddies. But this is Autoblog, so we're not even going to try to suss out a plot so thin it won't hold a spittle globule's worth of water. We'll just go over the cars. Transformers: Rise of the Beasts | Official Final Trailer (2023 Movie) Porsche 911 Carrera RS 3.8: Mirage So far the star of the film, car-wise, looks to be a blue-on-silver 964 Porsche named Mirage that is voiced by Pete Davidson. It's been the most promoted of the movie cars, even more so than formerly central characters like Bumblebee and Optimus Prime. Except, this isn't just any ordinary 911; it's a Carrera RS 3.8, a European-exclusive model of which Porsche only built 55 units. As the name implies, it came with a bored-out M64 turbo flat-six as opposed to the 964 Turbo's 3.6. It wore the Turbo's wide-body badonk with a bi-level rear wing, but Porsche reportedly stripped out 570 pounds' worth of weight despite embiggening key performance parts like brakes and wheels. Fortunately, no actual RS 3.8s were used in the movie. Producers instead built five cars for different purposes — shooting closeups of actors, jumps, the obligatory driving backwards real fast — out of lesser 911s. However, the sound department did record the engine note of an actual RS 3.8 for accuracy, as the higher crank speeds of the 3.8 have a distinctive sound.  In the original 1984 Transformers lineup Mirage was a Ligier JS11 Formula 1 car, complete with faux Gitanes cigarette branding (on a children's toy!). An F1 racer would raise an eyebrow on the streets, so it made sense to update to a street-legal sports car. If you're wondering why this Porsche isn't the character Jazz, whose original vehicle mode was an ultra-cool Martini-liveried Porsche 935, well, he was remade into a Pontiac Solstice voiced by Darius McCrary during the GM product placement rewrite in 2007's Transformers reboot, then unceremoniously killed. 1977 Chevrolet Camaro: Bumblebee Formerly the franchise star, Bumblebee gets far less screen time in the trailers. He's still a Camaro, but because Transformers: Rise of the Beasts takes place in 1994 he's not a fith-gen.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
