Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."

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.

President Trump's new limo spotted testing at high speed

What you're looking at is no ordinary limo. Look past the swirly camouflage and you'll see what appears to be a Cadillac, but don't let those looks fool you. This is the new Beast, otherwise known as Cadillac One, and codenamed by the Secret Service as Stagecoach. This is the car that will shuttle President Trump to and fro. It's hard to get a sense of scale from these images, but this car is huge. It's very likely built atop a heavy-duty truck platform, which is necessary due to the thick armor-like bodywork that's hermetically sealed to keep POTUS safe and sound. It's hard to tell for certain, but it appears this Beastie is riding on Goodyear Regional RHS II tires, which would otherwise be used on trucks and buses. Translation: this thing is heavy. The Beast is ostensibly badged as a Cadillac, and it wears the latest version of Caddy's corporate grille, badge, and upright headlamps at the front. From the rear, there's a hint of Rolls-Royce Phantom, with rear glass that tapers elegantly into the deck lid. In between is a massive slab-sided passenger compartment that's rumored to seat as many as seven passengers. These shots were snapped at GM's Milford Proving Grounds. It seems The Beast is undergoing some high-speed tests, though high-speed here is relative. Those Goodyears are only rated for 70 miles per hour or so, and we doubt the big 8.1-liter gasoline-fueled V8 engine is geared to push the President much faster than that, anyway. Related Video:
