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."

Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

8 cars we're most looking forward to driving in 2015

Now that 2014 is officially in the books, it's time to look ahead. And following our list of the cars we liked best last year, we're now setting our sights at the hot new metal that's coming our way in 2015. Some of these, we've already seen. And some are still set to debut during the 2015 auto show season. But these are the machines that keep us going – the things on the horizon that we're particularly stoked to drive, and drive hard. Jeep Renegade Not the Chevrolet Corvette Z06. Not the Ford Mustang GT350. Not the new John Cooper Works Mini. Nope, I'm looking forward to the adorable, trail-rated Jeep Renegade. And that's because I really, really, really like our long-term Jeep Cherokee Trailhawk. I do not, however, care too much for the Cherokee's looks, and I really don't like its $38,059 price tag. The Renegade Trailhawk, meanwhile, promises much of the same rough-and-tumble character as its big brother, but at what we expect will be a more reasonable price (I'm personally wagering on the baby Jeep's off-road model starting at no more than $23,000). With a 2.4-liter four-cylinder and a nine-speed automatic, it should also be a bit easier to fill than the V6-powered Cherokee. Also, I can't help but love the way the Renegade looks. It's like someone took a Wrangler, squished it by 50 percent and then handed it off to George Clinton for a healthy dose of funk. The interior, with its bright, expressive trims and color schemes should also be a really nice place to spend some time. I'll be attending the Renegade's launch later this month, so I'll have a much shorter wait than my colleagues. Here's hoping the baby Jeep lives up to my expectations. – Brandon Turkus Associate Editor Mazda MX-5 Miata Here's an uncomfortable truth: I'd rather spend a day driving a properly sorted Mazda MX-5 Miata of any generation on a winding road than I would nearly any other vehicle, regardless of power, price or prestige. It's not just that I prize top-down driving and enjoy the Miata's small size because it gives me more road to play with. I just find there's more motoring joy to be had with high-fidelity handling and an uncorrupted car-to-driver communication loop than I do with face-distorting power or grip – let alone valet-stand gravitas. But perhaps most of all, I love Miatas because they can deliver that level of feedback and driver reward at modest speeds that won't put the locals on edge or endanger lives – you can use more of the car more of the time.
