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."

2020 Cadillac CT5 loses the fake scoop

Well folks, the inevitable has happened. The 2020 Cadillac CT5 luxury sports sedan prototype has shed its hood scoop. Yes, we're as disappointed as you are that instead of being outrageous and brash, Cadillac is still going to try to be classy, understated and luxurious when it comes to its mainline models. And yes, we're being sarcastic here ... but there's a part of us that would kind of like to see the scoop survive. Anyway, the good news is that the scoop is only one of a few bits of fake bodywork and camouflage that the CT5 has shed. As such, we get our best look yet at the new Cadillac sedan, and it looks pretty good. The grille is very wide and not nearly as tall as the prominent prows of current Cadillacs. It actually doesn't even look as tall as the grille of the Escala concept that inspired the CT5's design. The profile of the CT5 isn't too radically different from existing Caddies, with a long hood and a short trunk. It is still a conventional sedan, though, and not a sedan-like hatchback like the Kia Stinger and Audi A5 Sportback and A7. This is evident by the open trunk lid our spy photographer caught. The taillights also continue to be slim and vertical, though we can't quite tell if they will have a horizontal elements at the bottom like on the XTS and XT4. The car also has very bold and thick angular exhaust tips. We expect the CT5 will go into production in 2019 as a 2020 model, and it will likely take the place of both the CTS and ATS, but not be much smaller than the CTS. It will likely use versions of existing Cadillac engines including the 2.0-liter turbo four-cylinder, naturally aspirated 3.6-liter V6, and twin-turbo 3.0-liter V6. We wouldn't rule out the 4.2-liter twin-turbo V8 for a potential CT5-V in the future. Related Video:

Gimp Pimp and Aqua Volvo at 24 Hours of LeMons | Car Club USA

Car Club USA heads to Sonoma, CA where the Gimp Pimp Cadillac and Aqua Volvo will take on all the crazy, sub-$500 competition at the 24 Hours of LeMons endurance race. "Over the last 30 years, car racing has gotten extremely serious and extremely expensive and it just seemed like there was a real need to make it accessible again," said LeMons founder Jay Lamm. The result is a series of endurance races across the US and Australia where all you need to join the fun is a junky car and some basic safety equipment. "It's just fun, compared to pro racing," said Wendy Epstein, driver of a 1979 Volvo 242 in bright "Aqua Volvo" livery. "24 Hours of LeMons is a form of racing that is designed to be cheap and easy, and anybody can do it," said Bill Manfroy, driver of the Gimp Pimp, a 1996 Cadillac SLS with some important modifications. "Part of what makes the Gimp Pimp Cadillac so special is that it does have hand controls, so it gives access to people like me that ordinarily get to race." "Which makes it perfect for LeMons."
