2016 Chevrolet Camaro: Notes from the reveal

The 2016 Chevrolet Camaro debuted Saturday evening in Detroit at an enthusiast-oriented event near the city's IndyCar course. While the big news was the Camaro's 200-pound weight loss, tighter chassis, and a snorting new V8, plenty of other morsels of Camaro info came out. Here's some of the more interesting stuff we heard. • The 2.0-liter inline four-cylinder is the first turbocharged engine in a Camaro. • The LT1 borrowed from the Corvette Stingray marks the third time a Camaro has used an engine with that badge. It was previously used in 1970-72 (Z/28), 1993-97 (Z/28), and 1996-97 (SS). • The Camaro was revealed in a tent before nearly 1,000 enthusiasts, General Motors executives (including CEO Mary Barra) and mere feet from the Grand Prix course where IndyCars will run in two weeks. • Chevy hopes to continue to attract new customers with the Camaro and said 63 percent of the fifth-generation buyers were new to the brand. • GM product boss Mark Reuss neatly summed up the Camaro's handling character. "It's wicked fast and extremely nimble." • Reuss on the design goal: make it "look like a car for tomorrow instead of a car from yesterday." • Reuss' first car was a 1967 Camaro, and he's reiterated his passion for the car. "People want to be seen in a Camaro, and that never goes away." • Chevy North America president Alan Batey said he plans to line up a red Camaro as soon as the order bank opens. We assume he'll have early access to that. • Though the appearance is similar, the sixth generation of the Camaro appears a little sleeker and is more aerodynamic thanks to 350 hours in the wind tunnel. Only two parts, the SS badge and the rear bow-tie emblem, are carryover. • Al Oppenheiser, the Camaro's chief engineer, said most of the options (except Magnetic Ride Control, which is SS exclusive), will be offered on the inline four. The engine will be capable of propelling the Camaro to a sprint to 60 miles per hour in well under six seconds. "We don't want to ... make it feel like an excuse car," he said. • Without revealing specifics, Oppenheiser said every Camaro variant will be faster than the model it replaces. •The interior is vastly improved. We got an up-close look in the cabin of one of the cars revealed with a red and white layout, and the materials are much better. The setting is more colorful, and 24 different ambient lighting shades are available. Related Video:

GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
