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.

Junkyard Gem: 1993 Cadillac Allante

The General's Cadillac Division had lost much of its status as a world-class styling and engineering innovator by the 1980s, while younger rich Americans signed on the line which is dotted for European luxury machines packed full of futuristic technology. Something needed to be done to win back the hearts of those buyers, and that something was the Cadillac Allante two-seater. Here's a final-model-year Allante, complete with one of the very first Northstar V8 engines, found in a Denver yard. The overhead-valve Cadillac V8 engine of 1949 shook up the automotive world, and the double-overhead-cam Northstar V8 of 44 years later had a similar effect. Finally, a high-revving, smooth-running modern V8 to compete with those pesky European and Japanese carmakers! Only the Allante got the Northstar at first, with other Cadillac models following soon after. After the underwhelming power output of the pushrod HT4100 V8s used in the 1987-1992 Allantes, the upgrade from 200 horses to 290 helped boost sales of the '93 to the highest annual figure ever achieved by the model: 4,670 cars. Unfortunately for GM, production costs of the Allante proved to be murderous in the long run. Shortened Eldorado frames were loaded onto specially-fitted 747s in Detroit and flown to Pininfarina's new Allante factory in Italy. After Pininfarina built the bodies, they got loaded onto the 747s, flown back to Detroit, trucked to the Hamtramck assembly plant, and given running gear there. GM called this system the "Allante Air Bridge" and it cost plenty. The cars looked both futuristic and Italian, which they were, but the Allante's price tag stood at heights far above those of the rest of the Cadillac line: $59,975 in 1993, or about $108,500 in 2020 dollars. You could buy a rear-wheel-drive BMW 850Ci with a 282-horse V8 and manual transmission for a mere 10 grand over the Allante's cost that year, or a Jaguar XJS convertible for just $56,750. The Allante had front-wheel-drive and a not-so-modern four-speed automatic transmission, which hurt sales among the enthusiast types who flocked to Cadillac showrooms for the CTS-V a decade or so later. No European machine of 1993 could top the Mars Base appearance of these vertically-arranged, all-pushbutton HVAC/audio controls, though.

2016 Cadillac ATS-V First Drive [w/video]

If you get hot and bothered for hot-rodded sedans and coupes, you probably know that Germans have long dominated that cutthroat scene. For years, the Audi RS/BMW M/Mercedes-AMG triumvirate has ruled the microcosm of grunty, mid-level luxury cars. But a funny thing happened when Cadillac's first V car hit the market in 2004. Since the CTS-V crashed the high horsepower party, German tuning houses started thinking less about the "Daddy's Caddy" stereotypes and more about the next imminent threat – in this case, the inevitable high-horsepower spinoff of the smaller, nimbler Cadillac ATS. The standard ATS' defense against the German triad hasn't been triumphant so far (GM's Michigan plant was idled for three weeks in 2014 due to excess inventory), but the souped-up 2016 Cadillac ATS-V presents a fresh bid to put the Teutonic competition on alert. The ATS-V's flared bodywork and quad exhaust pipes offer bits of visual shock and awe, but significant hardware upgrades back up the go-fast looks. Front and center is a twin-turbocharged, 3.6-liter V6 with reworked internals including a charge-air cooler, titanium connecting rods, and titanium-aluminide turbines. The new engine produces 464 horsepower and 445 pound-feet of torque, up a staggering 262 hp and 173 lb-ft compared to a base, four-cylinder ATS. Those output figures eclipse the BMW M3/M4 (425 hp, 406 lb-ft) and Audi RS5 (450 hp, 317 lb-ft), but lag slightly behind the V8-powered Mercedes-AMG C63 (476 hp, 479 lb-ft), and more so the C63 S (503 hp, 516 lb-ft). The chassis benefits from several structural braces, most notably a shear panel intended to boost front-end stiffness. Extra poundage from the add-ons are minimized through lighter-weight materials – in the case of the shear panel, stamped aluminum. Cadillac says though it intended to make the ATS the quickest car in its segment (stated 0-60 mph times between 3.8 and 3.9 second virtually match the BMW M4 and Mercedes-AMG C63 S' 3.9 figure), the development team says they also focused on subjective qualities like turn-in quickness and steering response. As such, toe links have been replaced with ball joints, mounts have been retuned, and reworked magnetic damping offer greater responsiveness. Six suspension bushings have been stiffened and ten have been completely redesigned, and the Performance Traction Management system that tames beasts like the Corvette Z06 and Camaro ZL1 also helps lay down power in the ATS-V.
