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.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
