GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

2021 Cadillac CT4-V Road Test Review | V is for Deja Vu

We now know that the 2021 Cadillac CT4-V is not the performance pinnacle of the line – that would be the 472-horsepower Blackwing. As it is, all the outrage spewed in the direction of Cadillac when it announced the once-great CT4-V was being downgraded to more pedestrian levels was ultimately much ado about nothing. Still, there's a kernel of truth to the notion that the new CT4-V (or CT4 V-Series as it's also known) just doesn't go far enough – or more accurately, the gap between it and the supposedly lesser CT4 Premium Luxury trim is surprisingly small. After driving the CT4 Premium Luxury with the optional 2.7-liter "450T" engine, I wrote here on Autoblog, "It's legitimately fun. You can feel the immense strength of the chassis, as well as the impeccable suspension tuning when hustling the car along. You also just feel things. There seems to be less cushion and fewer 1's and 0's between you and the car compared to other sport sedans like the BMW 3 Series and new Acura TLX. The steering has a lot to do with it: consistently weighted, regardless of drive mode, without too much speed-based adjustment, and genuine feedback filtered through the steering wheel. At the same time, the CT4 seems far more grown up and sophisticated in its engineering than the various front-drivers it competes with on price." After driving the CT4-V five months later, I wrote some notes on my computer. I later discovered they were virtually identical in overall impression to what is pasted above. It was like I had driven the same car twice. The resulting conclusion: I'd really need to exuberantly drive them back to back to notice a difference, especially as both cars had all-wheel drive. Even then, maybe not. It's perfectly plausible that many won't even notice a difference at all.  The all-wheel-drive point is key, however, because it means this CT4-V did not have the rear-drive version's Magnetic Ride Control 4.0 that always does wonders for a car's ride and handling. Maybe it would do so again here, but it's not like the CT4's ride or handling, regardless of flavor, needs much help. Much like the Premium Luxury 450T, the AWD CT4-V's fixed "performance" suspension provides a terrific balance of achieving a fast-attack pace in the mountains while not beating you up everywhere else. It absorbs bumps well and is neither crashy nor harsh. In other words, I didn't miss Magnetic Ride Control.

GM Design shows what could have been and what might be

We periodically like to check in with GM Design's Instagram account to see what they're cooking up. Even better is when we catch a glimpse of an alternate history of what legendary designers from The General's past were thinking, though those ideas may not have made it into production. This week, for example, the account posted some illustrations from George Camp, whose career at GM spanned nearly four decades, from 1963 to 2001. One of the renderings is of what appears to be a 1971-72 Pontiac GTO Judge, but with two headlights instead of the production unit's quad beams. The rear departs from the canonical version most dramatically, with a massive integrated wing. Other bits that didn't make the production cut include large side vents, a gill-like side marker and rectangular intakes below the headlights that wouldn't be out of place on a modern design today. Amazingly, from what we can make out of the date, it appears that the drawing was done sometime in 1965, which makes it quite prescient.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) There's also a very aerodynamic interpretation of a Corvette ZR-1. To our eyes it splits the difference between the 1986 Corvette Indy concept and a fourth-generation F-body Pontiac Firebird, so perhaps parts of Camp's work on this sketch did make it into physical form. There's also a radical sports car concept from May 1970 that resembles the Mazda RX-500 concept from the same year, a Syd Mead-looking Cadillac coupe, and an Oldsmobile with a cool take on the company's trademark waterfall grille and elements of the Colonnade Cutlass at the rear. Other recent posts include a FJ Cruiser-like off-road EV, a sleek coupe with the Chevy corporate grille, and a rendering of a Silverado-esque pickup that looks far better than the current production version.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) It's pretty easy to lose hours in the account, but it's always fascinating to see GM's visions of what could have been and what might be.

To top it off, if youÂ’re stuck way in the back, thereÂ’s Conversation Enhancement, so you wonÂ’t have to yell in order for the driver to hear what youÂ’re saying.  With all of this technology, itÂ’s easy to forget the original purpose of the Escalade, to get you from one place to another, in style, which it does incredibly well thanks to a 420 horsepower, 6.2L V8. Plus, this Escalade comes with something the others donÂ’t: $20,000 in cash. Here's what we said about the 2021 Escalade in our First Drive review: "The 6.2-liter V8 remains a gem of an engine. ItÂ’s powerful and flexible, and the 10-speed makes great use of its strengths. It's hardly fuel efficient, though. Over the course of our 58-mile test loop, we averaged just under 16 mpg, which pretty much confirms the EPA's ratings of 14 mpg in the city, 19 mpg on the highway and 16 combined. The latter is 2 mpg worse than the more powerful Navigator, a number that amounts to many hundreds of dollars in annual fuel costs. We would have liked to spend some time with the new diesel engine for comparison, but both it and the Super Cruise option are coming later this year, so that will have to wait, but based on the EPA figures for GMÂ’s full-size pickups with the same engine, weÂ’d expect somewhere in the neighborhood of low 20s combined from the oil-burner. "As delightful as the EscaladeÂ’s powertrain is, thatÂ’s not its standout feature; that honor goes to the suspension. All but the base model Escalade can be equipped with CadillacÂ’s fourth-generation Magnetic Ride Control.

How Indy 500's JR Hildebrand made an emergency pitstop in Goodland, Kansas

INDIANAPOLIS, In. – Race driver JR Hildebrand is an Indianapolis 500 celebrity, but last week on his way to Indy he was just another repair job at AlexÂ’s Radiator and Auto Repair in Goodland, Kansas. Well, not just any repair job. Hildebrand, a true car guy whoÂ’s just as comfortable driving his bagged 1960 Cadillac Coupe de Ville as he is a 230-mile-per-hour Dallara IndyCar, decided to pull the grand old ride out of storage in Boulder, Colorado, and cruise 1,100 miles to Indianapolis Motor Speedway. At 33, Hildebrand loves the classics, especially cruising in a ride nearly twice his age. It helps him separate from the pull of Twitter, Instagram and text messages before two weeks of foot-to-the-floor stress. Interstate 70 would be his perfect world. Except Â…           View this post on Instagram                       A post shared by JR Hildebrand (@jrhildebrand) “It was highly eventful for the first 300 miles,” said Hildebrand, who is practicing this week for his 11th start in the 500 on May 30.  The Caddy, a 390-powered pink beauty he calls Rosie, “had been sitting for a year, but it fired right up” and cruised just fine early in the trip. But as it approached the Colorado-Kansas state line, the suspension's airbag controller started flickering, the windows were slow to roll up, the gas gauge didnÂ’t work and the engine started to stumble. “IÂ’m thinking maybe IÂ’m only getting seven miles per gallon and IÂ’m out of gas,” Hildebrand said. “So I peeled off, ran a light and got to a gas station. It only took 12 1/2 gallons and was dead. ItÂ’s pretty unlikely that the collector in the fuel tank was leaving six gallons in this thing. I took a jump, and once I got it fired up, I got it back on the road and it ran fine for another 40 or 50 miles, and then the same thing started to happen. I pulled in and got another jump." (His wife Kristin was following behind in their Subaru, along with their dog). He stopped in Goodland and bought a new battery, “figuring the battery was toast at that point, whether that was the problem or not,” he said. “They did their diagnostics thing at the parts store, and it wasnÂ’t totally clear what was wrong.” Assuming the problem was somewhere in the charging system, he headed toward a nearby NAPA only to find it was closed. Along the way, though, he noticed AlexÂ’s Radiator and Auto Repair.

Mystery Cadillac Escalade prototype spied testing on public roads

This mystery Cadillac Escalade prototype could be a rumored V model featuring a supercharged LT4 V8. This prototype, sporting a fancy exhaust and other unique elements under fairly elaborate camouflage, was spied testing on public roads in Michigan.  Since it's still quite comprehensively disguised, we can't say much for certain about what this prototype has going on underneath. We can see a new set of wheels, a quad-tip exhaust and what appears to be a redesigned lower front bumper, but our spies didn't indicate anything else definitive — not even the telltale whine of a supercharger. That seems a glaring omission, given that a V model would almost certainly be powered by the same supercharged V8 found in the CT5-V Blackwing, where it is expected to develop well north of 650 horsepower.  Cadillac chief engineer Tony Roma has previously suggested that more V-badged cars are in the pipeline without confirming which ones or when to expect them. An unverified report published in February 2021 claims the Escalade's 6.2-liter V8 will soon receive a 200-horsepower bump thanks to a factory-backed, dealer-installed supercharger; a full-fledged V model would take that formula a step further. If you're not familiar with Cadillac's latest performance offerings, "V" models are now the mid-range performance variants, similar to Audi's "S" cars in that they offer a bump in power and handling but stop short of being full-blown track monsters. That treatment is reserved for the new "Blackwing" nameplate, which was derived from the twin-turbocharged V8 of that same name that was originally slated to power those range-topping models.  Related video:

2023 Cadillac Lyriq vs Tesla Model Y, Audi E-Tron, Jaguar I-Pace | Specs compared

The 2023 Cadillac Lyriq is the latest electric luxury crossover to enter a quickly growing segment. It brings with it the company's trademark creased design language along with high-tech features and an impressive amount of range. The Cadillac also happens to have a price and specifications that put it square in the middle of a competitive group, so we had to line up the numbers to see how it compares. We've gathered up a selection of premium electric crossovers including the Tesla Model Y, Audi E-Tron and Jaguar I-Pace, all of which seem like the closest rivals for the Cadillac. We've assembled all the raw numbers in the chart below. We've also got some additional analysis below that. And now, onto the data. Power, range, efficiency Interestingly, the Cadillac is the least powerful of the bunch. This is a bit surprising considering that GM will have a 1,000-horsepower electric Hummer pickup coming out soon. But in the Lyriq, Cadillac only uses a single electric motor powering the rear wheels. While its 340 horsepower and 325 pound-feet of torque should be more than adequate, it falls short of all the dual-motor, all-wheel-drive competition. Because Tesla does not provide horsepower or torque numbers, we're not sure how much the base model makes. We assume it's close. The true power fiends will likely want the optionally available Model Y Performance, though. It also doesn't have publicized power numbers, but its 0-60 mph time of 3.5 seconds suggests its substantially more powerful than the other crossovers, here. Power is all well and good, but range is arguably more important for an electric car. The Tesla is on top, here. The base Long Range trim has an estimated range of 326 miles. The company doesn't specifically say how large the battery is for it or the Performance, which goes 303 miles. The Cadillac is close behind with a current estimate of more than 300 miles on its 100-kWh battery. Cadillac doesn't say whether that number is the gross amount or the usable amount. The Audi and Jaguar lag behind with less than 250 miles from their 95- and 90-kWh batteries, respectively. Audi is the only company that notes that the usable capacity is less than the total, which is a common strategy employed to extend the life of the battery and to maintain consistent ranges over time. 2020 Audi E-Tron View 13 Photos While not as broadly discussed as range, we also wanted to touch on efficiency.

2023 Cadillac Lyriq production model revealed with range, power, price

We got our first look at the Cadillac Lyriq's design last August, and now the company is revealing the official production version of the electric crossover. The good news is that it looks almost identical to the preproduction version no matter where you look, inside or outside the car. It has the same long hood, low roof, creased body work, illuminated grille and groovy taillights. The interior retains the 33-inch instrument and infotainment screen and wood and metal trim. Only detail changes to things like the camera in the grille and the reworked control knob in the center console distinguish it from the concept. So if it basically looks the same, what's new here? Well, we finally have specifics on all the stuff that powers the concept-car body. At launch, the Lyriq will only be offered with a single motor and rear-wheel drive. The motor makes 340 horsepower and 325 pound-feet of torque funneled through a single-speed transmission. Supplying the motor with juice is a 100-kWh battery, though Cadillac didn't specify if that's the usable capacity or gross capacity. Cadillac estimates that the battery will provide more than 300 miles of range on a single charge. The initial models will be equipped with on-board charging equipment that can handle 19.2-kW Level 2 charging and 190-kW DC fast charging. The former can add 52 miles of range in an hour, and the latter can add 76 miles of range in 10 minutes and 195 miles in half an hour. Cadillac has made no mention of an 800-volt extra-fast DC charging system like in the GMC Hummer EV. There's a chance a system like that could be offered later, just like the forthcoming all-wheel-drive Lyriq variant. The Lyriq rides on multi-link independent suspension at all four corners, using "passive-plus" shocks, so it won't be adaptive or use GM's fancy magnetic suspension, at least at launch. Braking is provided by large 17-inch rotors at the front and 18-inch units at the back, welcome additions for the 5,610-pound crossover. Cadillac also gave us some basics on what equipment will be offered with the first run of Lyriqs. Only two colors, a silver and a black, will be available to begin with, and another silver will come a tad later. We imagine more colors will be offered on later Lyriq models. The interior comes in gray or black. Twenty-inch wheels are standard with 22-inch examples available as an option.

GM and LG Energy Solution will build their second battery plant in Tennessee

DETROIT — General Motors and South Korean joint-venture partner LG Energy Solution on Friday said they will build a second U.S. battery cell manufacturing plant, revealing plans for a $2.3 billion factory in Spring Hill, Tennessee. The planned 2.8 million-square-foot plant, scheduled to open in late 2023, will employ 1,300 people and will have production capacity of about 35 gigawatt-hours, similar to the companies' Ultium Cells joint-venture plant in Lordstown, Ohio, as they move to respond to the growing demand in the electric vehicle market. The plant's capacity would enable it to supply battery packs for more than 500,000 electric vehicles a year. "The addition of our second all-new Ultium battery cell plant in the U.S. with our joint venture partner LG Energy Solution is another major step in our transition to an all-electric future," GM Chief Executive Mary Barra said. The United Auto Workers on Friday called on GM to ensure the new plant is staffed with union-represented workers, which GM officials have said would be determined by the employees. LG Chem said in a regulatory filing that its LG Energy Solution unit will invest $933.5 million in the plant between this year and 2023. GM and LG Energy Solution will use a different, less-expensive battery chemistry in Tennessee than the one to be used in the Lordstown plant that opens next year, sources previously told Reuters. Sources have said the No. 1 U.S. automaker will need more battery plants beyond Tennessee to meet aggressive EV targets, including projected sales of more than 1 million EVs globally in 2025. GM's longer-range target includes halting sales of light-duty gasoline and diesel-powered vehicles by 2035. Most battery manufacturing is currently concentrated in China and Korea, while Tesla and Japanese partner Panasonic largely control most U.S. battery production. When it opens, the new GM-LG battery plant will supply batteries for the Cadillac Lyriq crossover EV that GM is slated to start building at its nearby Spring Hill assembly plant next year. LG is expected to supply the batteries from Korea until then. Supplier sources said a second Cadillac electric crossover, called Symboliq, is expected to join the Lyriq in production at Spring Hill in 2024, along with two new electric crossovers for Honda and its premium Acura brand. GM said in October it would invest $2 billion in Spring Hill to build EVs.

NHTSA investigating nearly 750,000 GM models over non-deploying airbags

Nearly 750,000 vehicles built by Chevrolet, GMC, and Cadillac are the subject of a National Highway Traffic Safety Administration (NHTSA) investigation due to non-deploying driver-side airbags. While the investigation is ongoing, the agency believes the issue is likely due to rust particles that form on the inflator's connection terminal interface. The list of nameplates included in the investigation includes Chevrolet's Silverado, Tahoe, and Suburban, GMC's Sierra, Yukon, and Yukon XL, plus Cadillac's Escalade, Escalade ESV, CT4, CT5, and XT4. All of the potentially affected vehicles are 2020 or 2021 models, according to a bulletin published on the NHTSA's website. Investigators launched the probe in April 2021 after 15 consumers reported airbag-related issues, including nine who said an airbag malfunction light appeared in the instrument cluster. More alarmingly, the NHTSA is aware of six accidents that caused significant damage to the car's front end yet didn't trigger the driver's airbag. It adds that there are no fatalities linked to the issue, but there are six crashes and eight injuries reportedly blamed on it. No evidence suggests this problem is related to the millions of potentially deadly Takata inflators recalled over the past few years. General Motors is aware of the defect. It sent a technical service bulletin (TSB) to its dealers in March 2021 to address the aforementioned warning light. The note explains the issue is due to "rust particles in the connection terminal interface of the driver's airbag inflator." The company hasn't issued a safety recall yet, however. Whether it will partially depends on the NHTSA's findings. It's currently looking into the scope and the severity of the problem, and it wants to understand its implications on driver safety. Investigators will decide whether General Motors needs to recall the 749,312 cars that are part of the probe when they close their investigation. General Motors has already spent a significant amount of money replacing defective airbag-related parts in its cars. In November 2020, it was ordered by the American government to recall nearly 6 million pickup trucks and SUVs equipped with potentially dangerous Takata airbag inflators. It repeatedly argued that testing proved the inflators were safe, and it petitioned the agency four times starting in 2016 to avoid a recall, which cost an estimated $1.2 billion (about a third of its net income in 2020).
