Chevrolet Silverado, GMC Sierra could get independent rear suspension

The Chevrolet Silverado and the GMC Sierra could reportedly receive a variant of the four-link independent rear suspension found under the new Tahoe and Suburban. While that's not a surprise, a recent report suggests electrification, not comfort, convinced General Motors to make the change. Replacing the time-tested solid rear axle with an independent suspension will improve comfort, handling and off-road prowess, while adding weight, and likely making the trucks a little bit more expensive. It's a fair trade-off, but GM Authority learned the real reason for the swap is that at least one of the pickups will spawn an electric model, and it's more difficult to package a bulky battery pack around a solid rear axle. The independent rear suspension takes up far less space, even if it has more moving parts. General Motors will build its first regular-production electric pickup on an evolution of the Silverado's T1 platform named BT1, according to the same source. The b stands for -- you guessed it -- batteries. The firm reportedly doesn't want to make two suspensions for cost reasons, so the independent setup will come standard regardless of whether the truck runs on gasoline, diesel, or electricity. As a bonus, Chevrolet and GMC could choose to offer their T1-based trucks with Magnetic Ride Control or an air suspension, options available on the 2021 Suburban and Tahoe. The independent rear suspension will also find its way to the next-generation GMC Yukon due to be revealed January 14, and to the 2021 Cadillac Escalade scheduled to make its debut February 4. The long-rumored, born-again Hummer will get it, too, because it will arrive as an electric model built on the BT1 platform. It's worth noting none of this is official, and General Motors has remained quiet about what's next for its new suspension design, and what will be under its electric truck's sheet metal. If the GM Authority report is accurate, the Silverado (pictured) and the Sierra could ditch their solid rear axle for the 2021 model year. The change will likely be accompanied by other tweaks inside and out. Featured Gallery 2019 Chevrolet Silverado 1500 View 16 Photos Chevrolet GMC Truck

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

GM raises 2023 guidance on strong sales, higher profits

General Motors beat first-quarter profit estimates and raised its full-year earnings and cash-flow guidance after vehicle demand at the start of the year surpassed expectations. Its shares rose in premarket trading. GM made $2.21 a share in adjusted profit in the first quarter, compared to a consensus forecast of $1.72 a share. Revenue rose 11% to $39.99 billion, it said Tuesday, which was more than the $39.24 billion analysts expected. The stronger results stem from rising sales in the US, even in the face of higher interest rates and inflation. GM executives said demand was strong enough to revise 2023 guidance upward, boosting profit estimates for the year by $500 million to between $11 billion and $13 billion. “We did it with strong production and inventory discipline and consistent pricing,” GM Chief Financial Officer Paul Jacobson said on a call with journalists. “All in all, weÂ’re feeling confident about 2023.” The Detroit automaker raised per-share full-year guidance to between $6.35 and $7.35, up from $6 to $7 a share, and said free cash flow would also increase by $500 million to a range of $5.5 billion to $7.5 billion.  GMÂ’s shares pared a gain of as much as 4.4% before the start of regular trading Tuesday, rising 3.5% to $35.50 as of 6:55 a.m. in New York. The stock was up 1.9% for the year as of the close on Monday.  North American Strength The automakerÂ’s sales were particularly strong in North America, where first-quarter earnings rose before interest and taxes rose to $3.6 billion. Vehicle sales rose 18% to 707,000 in the region. Jacobson said the company originally expected to sell 15 million vehicles in the US this year, slightly less than the 15.5 million annualized rate automakers foresaw in the first quarter. North American demand was enough to offset a weak performance in China, GMÂ’s second-largest market. The automaker continues to struggle in the country, where its vehicle sales fell 25% to 462,000 vehicles in the quarter. Profits from its joint ventures in the market slumped 65% to $83 million.  The market has struggled overall in the wake of Covid-19 restrictions and foreign automakers have had to overcome a growing preference for Chinese brands by competing on price, squeezing profit margins. The situation in China probably wonÂ’t significantly improve until the second half of the year, according to Jacobson. GM remains on target to sell 150,000 electric vehicles this year, the CFO said.
