Autonomous tech will drive motorheads off the road

While autonomous technology could make car travel much safer and more efficient — and automakers and marketers are salivating over the prospect of a "passenger economy" that could potentially generate $7 trillion by 2050 — those of us who enjoy driving are not so stoked. Experts have predicted that as autonomous vehicles are deployed in large numbers, human-driven cars eventually could be outlawed on public roads due to the carnage they create, which is currently more than 41,000 deaths a year in the U.S. alone and climbing. Such scenarios have driving enthusiasts envisioning a "Red Barchetta" style nightmare becoming reality, making Rush lyricist Neil Peart a clairvoyant as well as one of rock's most badass skin-pounders. But there could be a couple of refuges left for motorheads, and they won't be on public roads. As Popular Science's Joe Brown points out in a recent editorial, we're seeing a wave of vehicles being offered by legit mainstream automakers that aren't made for public roads. The poster child of this vanguard is the 2018 Dodge Challenger SRT Demon, which comes with a crate full of goodies that lets you turn the already formidable street-legal muscle car into a drag-strip dominator. Brown also notes that two out of five of the Ford GT's driving modes are for use on the track, "catering to the $450,000 machine's club-racing clientele." We're also currently enjoying the heyday of production off-road-ready pickups that kicked off with the Ford Raptor in 2009. The latest salvo in this escalating war of overachieving trucks is the Chevy Colorado ZR2 that can take on the likes of California's Rubicon Trail without issue. Brown also gives a shout-out to his magazine's Grand Award Winner, the Alta Motors Redshift MX, which "isn't even allowed on public roads" and is "meant for bombing around motocross tracks, big backyards and single-track woods trails." If you follow Brown on Instagram, you know that he's also a two-wheel aficionado, and he points out that sales of off-road bikes are leaving street machines in the dust. Sales of off-highway motorcycles rose 29 percent between 2012 and 2016, according to the ­Motorcycle Industry Council — compared to 6 percent for road-bike sales during the same period. "That's a nearly 400-percent drubbing," Brown remarks.

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."

Weekly Recap: Lincoln Continental serves up the style, Cadillac CT6 delivers the substance in New York

Lincoln and Cadillac grabbed the spotlight this week at the New York Auto Show in a dramatic fashion that evoked the brands' glory days. America's two luxury carmakers went toe-to-toe with their glittering reveals and plans for ambitious expansion. Both were selling their technology, style and the promise of a better future. Cadillac vs. Lincoln. At the Javits Center, 2015 seemed a lot like 1956. Neither company was interested in drawing comparisons with the other, which is fair, and accurate. They're in vastly different places in terms of sales and the pace of their turnarounds, but they hope to reach the same eventual destination at the pinnacle of the luxury-car world. Lincoln used the element of surprise to great effect with the Continental concept. A production version is still at least a year away, and the company was vague on details. Officially, we don't even know if it is front- or rear-wheel drive, though speculation abounds. Who cares? The seats can be adjusted 30 ways! The Continental also showed off a bold chrome grille that will be the new face of Lincoln. The blue bomber also rolled on blinged-out 21-inch polished aluminum wheels, used a 3.0-liter EcoBoost engine and had huge LED head lights with "laser-assisted" high beams. All of this resulted in almost blinding attention. The concept drew rave reviews, stirred controversy with Bentley designers who argued Lincoln ripped them off, and most importantly, pointed a way forward for the newly determined brand that hopes to compete with Mercedes, BMW, Audi, Cadillac and Lexus.

With production starting late this year, Cadillac had more specifics at the ready. Engines? Cadillac has a couple V6s and a turbo four for sure. It's working on a hybrid, and has considered a V-Series variant. It's based on a new rear-wheel-drive, aluminum-intensive chassis called Omega, features an advanced collision-mitigation system with automatic braking and has a cabin that's laden with "leathers, exotic woods and carbon fiber." It will be assembled at GM's Detroit-Hamtramck factory and goes on sale next year. At this point, Cadillac is more than willing to talk about every except for the price. The devil was not in the details for Cadillac, as evidenced by the CT6. But it wasn't for Lincoln either.
