2019 Chicago Auto Show Truck Roundup: Toyota, Ford, Chevy and Ram bring it

The 2019 Chicago Auto Show features an array of heavy-duty trucks, smaller trucks, other kinds of trucks, and well, more trucks. That means new versions of the 2020 Chevy Silverado Heavy Duty and 2020 Ford F-150 Super Duty, a refreshed 2020 Toyota Tacoma and a trick tailgate on the 2019 Ram 1500. Sound a little crazy? Morgan Stanley research says 68 percent of passenger vehicles sold in the United States last year were classified as light trucks. So actually, bring on the trucks! Here's some impressions on the Chicago reveals, plus our take on the 2020 Subaru Legacy sedan. — Toyota updated the 2020 Tacoma with some light but useful enhancements. An improved infotainment has new audio features and larger screens. The grilles and wheels are different, but nothing drastic. Toyota still offers nice differentiation across the Tacoma lineup, and the design tweaks are subtle but thoughtful. Toyota tends to stretch out the Tacoma's generations, so it's wise to keep modifying and iterating to keep pace in this competitive segment. — Staying with Toyota, the Land Cruiser Heritage Edition is a legit special model that fans of this historic nameplate will appreciate. An anchor of the Toyota line in the United States since 1958, the Land Cruiser's roots date to Toyota's 1951 BJ Series military vehicle. Two colors, Midnight Black and Blizzard Pearl, are exclusive to this model and look slick against the blacked-trimmed grille and lightly bronzed wheels. Inside, bronze stitching is used on the steering wheel, seats, center console and other parts. The best part? Land Cruiser spelled out in script on the rear pillar. It's a limited model (1,200 units) and pricing isn't out yet, but that badge is probably why you buy this SUV. — The 2020 Chevy Silverado HD gets imposing looks that differentiate it from the light-duty range, an eye-popping max towing capability of 35,500 pounds and some updated powertrain elements. A new gas-fed V8 that serves as the entry point is one of the highlights, and the 6.6-liter mill makes 401 hp and 464 lb-ft, up significantly over the old 6.0-liter. There's also a new Allison 10-speed transmission teaming with the Duramax diesel to achieve that lofty max towing figure. With an updated trailering system and a larger cabin, the Silverado HD range is comprehensively remade to fight Ram and Ford. — The 2020 Ford Super Duty is also redone, and like the Chevy line, it gets a new gas V8 checking in at 7.3 liters.

GM dealers unhappy about pickup prices

The backlash is beginning. Following General Motors' price hike of the Chevrolet Silverado and GMC Sierra last week, dealers across the country are expressing their ire over increasing prices in the face of rebates and discounts on trucks from Ford and Ram.
Speaking to Automotive News, Sam Pilato, the general manager at Dimmitt Chevrolet in Clearwater, FL, Silverados are "selling very poorly." W. Carrol Smith, the president of Monument Chevrolet in the heart of truck country, Texas, said, "[GM's] position is that the vehicle stands on its own and it doesn't need a bigger rebate. That's not what the market is telling us."
According to AN, that's the general attitude amongst Chevy and GMC dealers across the country, where the twin pickups are getting butchered in sales by competitors offering up to $9,000 off their sticker prices. Part of the problem for GM is that its trucks are arriving on the market near the end of the current F-150's lifecycle, a fact that Ford has taken advantage of.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.
