Cadillac, Buick and Chevy decisions impacted by worries abroad

European Concerns Drive GM, But Beware Of The French Connection
GM's bid to rationalize Europe will impact the products that will be offered domestically.
It seems that Europe is defining the future of General Motors more so than its home North American market. Having axed Saturn, Pontiac and Hummer, GM has done a fairly good job of repositioning its remaining four divisions, Cadillac, Chevrolet, Buick and GMC. Cadillac carries the luxury banner. Chevrolet is aimed at the masses with cars and trucks along with a nod to performance thanks to Camaro and Corvette. Buick bridges the premium gap between Chevy and Cadillac, while GMC offers a hardcore work/upscale proposition.

GM's latest production delays: Colorado/Canyon, Cadillac CT4/CT5, Camaro

DETROIT — General Motors Co extended production cuts in North America on Wednesday due to a worldwide semiconductor chip shortage that has impacted the auto sector. The U.S. automaker said its Wentzville, Missouri, assembly plant would be idled during the weeks beginning March 29 and April 5. It will extend down time at its plant in Lansing, Michigan, which has been idled since March 15, by two weeks. The action was factored into GM's prior forecast that it could shave up to $2 billion off this year's profit, spokesman David Barnas said. GM did not disclose how much volume would be lost by the move, but said it intended to make up as much lost production as possible later in the year. The chip shortage came as North American auto plants were shut for two months during the COVID-19 pandemic last year and chip orders were canceled, and as demand surged from the consumer electronics industry as people worked from home and played video games. That's now left carmakers competing for chips. Semiconductors are used extensively in cars, including to monitor engine performance, manage functions for everything from steering to automatic windows, and in sensors used in parking and entertainment systems. Vehicles affected by the GM production cuts include the mid-sized pickup trucks, the Chevrolet Colorado and GMC Canyon in Missouri, and the Cadillac CT4 and CT5 and Chevy Camaro cars in Michigan. Meanwhile, GM said its San Luis Potosi, Mexico, assembly plant, idled since Feb. 8, will resume production with two shifts beginning the week of April 5. Last week, GM said it was building certain 2021 light-duty full-size pickups without a fuel management module, hurting their fuel economy performance by one mile per gallon. Exacerbating the shortage is a recent fire at a Renesas Electronics chip plant in Japan. Barnas said GM was assessing the impact of the fire.  

Cadillac CT6 beefs up with 400-hp twin-turbo V6

Cadillac's engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6. Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here's what we know so far: The CT6's top engine will be a 3.0-liter twin-turbo V6. It's the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get. The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It's rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That's an improvement of 14 hp and nine lb-ft compared with today's 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it's the highest output for a naturally aspirated V6 that's SAE-certified and runs on regular fuel. Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions. The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS. Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options. The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac's creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.
