2017 Honda Ridgeline enters the landscape block war

In the test of pickup truck beds, if steel is apples and aluminum is oranges, Honda wants you to know that composites are pineapples. Chevy recently performed a test in which its own Silverado was pitted against its most obvious competitor, the Ford F-150. A loader dropped over 800 pounds of landscaping blocks into the two truck beds, and Ford's aluminum bed ended up with more damage than Chevy's steel bed. Check that test out right here. Honda apparently wasn't content to let Chevy throw stones alone. In a new test, the Japanese automaker replicated the block-drop test using its brand-new Ridgeline truck, which features a composite bed. As you'll see in the video above, there was very little damage to the high-strength plastic bed of the Ridgeline after a similar load of landscaping blocks were dropped from a loader. Without being on hand at any of these tests, we can't say with any degree of certainty that they match up in severity. But they all look pretty similar, and this is actually a test that Honda performed in front of journalists ( ourselves included) earlier this year. We visually inspected the composite bed of a Ridgeline after a demonstration just like the one on video above, and can confirm that there was basically no damage to Honda's truck. Chevy went an extra step by flinging a heavy toolbox into the Silverado and F-150; Honda didn't match that particular test. Does any of this matter? That's up to truck buyers and owners to decide, naturally, but we doubt anyone would actually dump a load like this into their own truck. And it's also worth noting that a heavy-duty spray-on bedliner would probably minimize damage to the metal surface below, whether steel or aluminum. If nothing else, it's memorable marketing.

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."

Chevy monitors drivers' biometrics while experiencing new Corvette Stingray

We tell you about what a car is like to drive every day, remarking on throttle response, steering weight and feedback, squat, dive, brake fade and a dozen or more other factors of performance. What we can't tell you, though, is what the car does to us - how its performance impacts us, physically. That's what makes this video series from Chevrolet so darn cool.
The Bow-Tie brand rented out Spring Mountain Motorsports Ranch, got several (very) different individuals together, strapped a bunch of sensors to their bodies to record biometric data ranging from heart rate to respiration to brain activity, and then handed them keys to the new Chevrolet Corvette Stingray. The results are explained in a series of videos, devoted to each driver, showing how different people react to the Corvette's performance.
If, like your author, you're a nerd for medical science, this is going to be a fascinating set of videos. If not, it's still pretty cool to see how the body of someone with racing experience, like Gran Turismo creator Kazunori Yamauchi, reacts to tracking a car like the Corvette Stingray compared to the owner of legendary Detroit barbecue joint, Slows BBQ. Take a look below for all six videos from the series, or hop over to the Corvette Vimeo channel for the interactive experience, where you can see all the different metrics.
