The U-2 spy plane needs high-performance cars to help land

Typically, aircraft deploy their landing gear from three main points. Most military aircraft, for example, deploy two gears at the back and one forward, like a tricycle. Some civilian aircraft flip the layout, with two in front and one in back - tail-draggers. The U-2 Dragon Lady is wildly different than any of these. With a 103-foot wingspan but a body that's just 63-feet long, the layout of the U-2 makes a traditional landing setup infeasible. Instead, the U-2 utilizes a pair of wheels, one up front and one in back. With such a bizarre layout, landings are so tough that since the U-2's earliest flights at Area 51, the US Air Force has used high-performance chase cars to guide the pilot down safely. The landing process isn't over there, though. As this video from Sploid shows, balancing out the aircraft to fit the detachable "pogos" – think training wheels for spy planes – is a comical procedure requiring a number of airman using their full body weight to even out the U-2. This video also recaps some of the great vehicles that have served as chase vehicles for this legendary spy plane. They include Chevrolet El Caminos, and the Fox-body Ford Mustangs so favored by the California Highway Patrol. For the last several years, the USAF has utilized products from General Motors, using fourth-generation Chevy Camaros, before switching over to the Pontiac GTO and most recently, the awesome Pontiac G8. It's fair to say that if you're a gearhead in the Air Force, this is the job you want. Check out the video, embedded up top.

'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).

General Motors shaking up its marketing... again

One of the things that dogs the full comeback of General Motors is the instability of its marketing. That part of the automaker got yet another big shakeup today when GM confirmed what I have been tweeting for a few days - strong rumors that the Chevrolet and Cadillac ad accounts are walking to new ad agencies.
Cadillac, GM's luxury brand, is going into review from Fallon Worldwide, Minneapolis and the indications are that Campbell-Ewald, Chevy's old ad shop, will end up with most or all of it. C-E just announced that it was moving from its long-time home in Warren, MI to a new downtown Detroit office next to Ford Field, just blocks from GM.
The other shoe to drop shortly will be the shift of GM's most important brand, Chevy, from Goodby, Silverstein & Partners of San Francisco to McCann-Erickson of Troy, MI. McCann used to be the agency for Buick and GMC, as well as GM's corporate advertising, and has retained some pieces of business over the last few years. Sources have even told us that it was McCann that did a lot of the creative work on Chevy's new ad platform, Find New Roads. (Not to be confused with a former McCann tagline for Saab, "Find Your Own Road.")
