Lutz dishes dirt on GM in latest Autoline Detroit

Bob Lutz sits down for Autoline Detroit - Click above to watch video after the jump
Autoline Detroit recently played host to Bob Lutz, and, as is always the case, the former General Motors vice chairman dished out some great commentary. Lutz was promoting his new book Car Guys vs. Bean Counters: The Battle for the Soul of American Business, and talk quickly turned to his role as it related to product development and high-level decision making at GM. While on the topic of brand management, Lutz revealed a few rather interesting tidbits about his former employer:
All Chevrolet vehicles were required to have five-spoke aluminum wheels and a chrome band up front, as part of the Bowtie brand's overall image.

'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).

Hot air balloons caught in high winds drag fullsize SUV

A sudden storm front whipped up enough wind to send some hot air balloons flying into the air in Wisconsin over the weekend. One ballon proved so energetic that it was able to drag a fullsize SUV across a field and into a stand of tents. The freak accident occurred at Balloonfest in Waterford, Wisconsin. Spectators were horrified as balloons dragged handlers to the ground and launched with terrified pilots clinging to their baskets. Organizers had started packing up the colorful balloons due to ominous storm clouds when the wind kicked up. "Happened just like that; it was crazy," Nathan Fricke, crew member, told Fox 6. Winds were clocked at 40 to 50 miles per hour. A balloon caught in the wind dragged a large SUV (we think a Suburban or Yukon XL) hundreds of feet and into a cluster of tents on the edge of the staging area where balloons were on display for festival goers. Considering that the SUV surely weighs well over 5,000 pounds, it's lucky that no one was injured in the incident. News Source: Fox6Now Weird Car News Chevrolet GM GMC SUV
