Cadillac Escalade reportedly getting 200-hp bump from supercharger

Cadillac is preparing to supercharge the Escalade, according to a recent report. The body-on-frame General Motors SUVs that it shares its basic underpinnings with are allegedly in line to receive a big increase in power, too. Released for the 2021 model year, the fifth-generation Escalade eschewed downsizing and launched with a 6.2-liter V8 as its standard engine. It develops 420 horsepower and 460 pound-feet of torque when it's naturally aspirated, and Motor Trend learned from an anonymous source that the optional supercharger will increase the first figure to anywhere between 600 and 625. The eight's torque output will undoubtedly go up, too. The supercharged Escalade won't outgun the sold-out Dodge Durango SRT Hellcat, which gets 710 horses, but it will pack a serious punch. It doesn't sound like the V8 will require significant modifications to handle the extra power because the supercharger kit will likely be installed by dealers, not on the assembly line. This strongly suggests that it's more of a bolt-on job than one that requires taking the engine out and apart to install stronger connecting rods and forged pistons, for example. ECU tweaks will be part of the package, too, and the fuel delivery system may require some upgrades. Interestingly, Motor Trend learned from Texas-based Hennessey that the SUV's ECU is locked to tuners, which adds credibility to the report. Motorists who want more power will need to go through official sales channels, then. Bigger brakes and a firmer suspension won't be part of the package — at least not yet. The same source outlined a true high-performance evolution of the body-on-frame behemoth that will be quicker and tighter to drive. Oddly, it's not being developed by the engineers in charge of Cadillac's V-branded models, according to the report. If the report is accurate, we'll learn more about the supercharged Cadillac Escalade in the coming months, and it might go on sale in time for the 2022 model year. Expect the supercharger to come with a four-digit price tag. Chevrolet's Tahoe/Suburban and GMC's Yukon/Yukon XL will reportedly be available with a supercharger, too.

Meet the mother-daughter team that's worked on almost every Chevy Volt

It's Mother's Day, and we're soft enough we love our mothers enough to share a new video from General Motors with you. In it, we meet Monique Watson (left) and Evetta Osbourne, a mother-daughter team that works at the Detroit-Hamtramck Assembly where GM makes the Chevy Volt (along with all of GM's other plug-in hybrids: the Opel Ampera, Holden Volt and Cadillac ELR). The two work side-by-side and have installed the lithium-ion battery pack on almost all of those vehicles - nearly 80,000 of them - since GM started making the pre-production Volts in 2009. In a prepared statement, Watson said that she likes working next to her mom, day in and day out, and they the two are totally in sync when it comes to putting the 400-pound, 16.5-kWh packs into the vehicle undersides. They two can also share stories throughout the day, and Watson said, "The arrangement has absolutely improved our relationship." Osborne started working at Detroit-Hamtramck in 1999, Watson since 2006. If you're driving a Volt today, you probably have them to thank for doing a bit of the work putting your car together. See a short video of them in action below. It's Always Mother's Day for Detroit-Hamtramck Duo Mother, daughter install lithium-ion battery pack in nearly all GM electric vehicles 2014-05-08 DETROIT – For Detroit resident Evetta Osborne, every day is Mother's Day. That's because she literally works side by side with her daughter, Monique Watson, at General Motors' Detroit-Hamtramck assembly plant. They have installed the lithium-ion battery pack on nearly every Chevrolet Volt, Opel Ampera, Holden Volt, and Cadillac ELR since production began. In fact, apart from vacation days and an occasional sick day, the mother-daughter duo has installed almost every battery pack since the Volt was in pre-production in 2009. The ELR launched earlier this year. All told – including Ampera – that's more than 80,000 electric vehicles. "We're a good team and our relationship is secondary when it comes to performing our jobs – but it's great to work alongside my daughter, said Osborne, a mother of five. Because the battery packs weigh more than 400 pounds each, automatic guided vehicles – robotic carts that use sensors to follow a path through the plant – deliver them just as the vehicle body structures glide into position overhead. The carts then lift the T-shaped packs, and Osborne and Watson guide them into the chassis and secure each one with 24 fasteners.

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.
