CA Chevy dealer allegedly adds $50K 'market value adjustment' to 2015 Z06

It seems to happen with every eagerly anticipated new car – dealerships, recognizing that crushing demand far outstrips the initial limited supply of a new model, inflate the price via a so-called "market value adjustment." We've seen it in the past with a number of new models, and now it's happening again with one of the Detroit 3's hottest vehicles. A dealership in Roseville, CA, outside of Sacramento, has allegedly attached a staggering $49,995 market value adjustment to a 2015 Corvette Z06. We say allegedly because, despite the evidence uncovered by BoostAddict, John L. Sullivan Chevy's online inventory listing doesn't display the price premium of the Z06 in question, a (normally) $93,965 model with the top-end 3LZ trim. It's unclear if either of the dealer's other Z06s, both 3LZs, one of which is in transit, will receive similar price adjustments. Now, legally, Sullivan Chevy isn't doing anything wrong here. Dealerships are under no obligation to observe a manufacturer's suggested retail price, a point General Motors' spokesperson Ryndee Carney pointed out to Autoblog via email. "For the Corvette Z06, Chevrolet has established a Manufacturer's Suggested Retail Price we feel is right for the market. Actual transaction prices, however, are the province of the dealer," Carney said, adding that a dealer zone manager will be discussing the price hike with the dealership. While we also reached out to the dealership over both the market value adjustment and the price of the Z06 as it appears on the company's website, we've yet to hear back as of this writing. Should they reply to our inquiries, we'll be sure to update you. Until then, we'd like to hear what you think about this case. Is Sullivan Chevy simply pricing the cars as high as it thinks the market can bear, or is this a cash grab for an hotly anticipated product? Have your say in Comments.

Chevy Silverado WT gets its own murdered-out trim pack

Media days for the 2015 Chicago Auto Show ended last week, but that hasn't stopped Chevrolet from adding just one more thing. The Bowtie brand showed off three new trim packages for its trucks in the Windy City – the Colorado GearOn and the Silverado Midnight and Custom – but protests from consumers over the price of these equipment packs has led the company to release a new trim group for its most affordable fullsizer, the Silverado WT. The $1,595 Black Out pack will be available on both the regular- and double-cab Silverado WT and offers a few simple, stylistic upgrades. Five-spoke, 20-inch black wheels are the headlining item, although Chevy will also include "deep tinted glass" and black bowtie badges both fore and aft. Available only in black (the company even paraphrases old Mr. Ford in its press release), the new package adds just enough to class up the otherwise dreary looking Work Truck. Chevy has only released one image for the time being, available up top. Dealers, meanwhile, are currently taking orders. Check below for the brief press release. Chevrolet Silverado Work Trucks Get Blacked Out DETROIT – Chevrolet is adding a $1,595 Black Out package for regular- and double-cab 2015 Silverado 1500 WT models. It includes 20" black painted aluminum wheels, P275/55R20 all-season blackwall tires, deep tinted glass and black bowties. Prices start at $28,895. The package is available for order now, and customers can have any color they want, as long as it is black. Editors' Note: Manufacturer's Suggested Retail Price excludes tax, title, license, dealer fees and optional equipment. Includes dealer freight charges and option package discounts. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.8 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature engaging performance, design that makes the heart beat, passive & active safety features and easy-to-use technology, all at a value.

'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).
