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."

GM drops price of Spark EV to $25,995; lease to $139/month

The drive to lower EV prices continues. GM announced today that the base model 2015 Chevy Spark EV 1LT would get a price cut to $25,995. That's $1,500 less than it used to be but the bigger news might be the lowered lease price. Instead of $199 a month, all that Chevy is asking for to get you into an all-electric Spark now is $139 a month (39 months, with no money due at signing), down from the 36-month, $199-a-month lease cost with a $999 down payment. Sadly, the number of states where the Spark EV can be bought is almost as small as the lease payment: the car is available only in California, Oregon and Maryland (well, Maryland won't be ready until the summer). GM is doing more than just lowering the MSRP. On top of the federal and state tax incentives available, GM is offering bonus cash in all three states ($1,000 in California, $1,200 in Maryland, and $3,500 in Oregon). If you're wondering why those numbers vary so much, take a look at the already-available state EV incentives in play: California offers $2,500 and Maryland $2,300. Somehow, they all balance out. If you do some addition with the $7,500 federal tax credit, you see that the Spark EV can be had for $11,000 off the MSRP no matter where you buy. If you qualify for everything, $14,995 is a darn good deal for an EV, especially one as fun as the Spark.

Depending on an individual's tax situation, the Spark EV is eligible for federal tax credit up to $7,500. "Chevrolet is committed to making EV driving more accessible, affordable and fun" said Steve Majoros, director of Chevrolet Car and Crossover Marketing. "The Spark EV is already the most efficient – and one of the most affordable – EVs you can buy. 2015 Spark EV customers will benefit from an impressive blend of technology, capability and low cost of ownership, now at an even more impressive price." California and Maryland Spark EV owners may also qualify for a $2,500 California state rebate or $2,300 Maryland excise tax exemption. Additional Chevrolet bonus cash is also available: $1,000 in California, $1,200 in Maryland, and $3,500 in Oregon. After full federal and state tax credits and Chevrolet bonus cash, the Spark EV could be as low as $14,995.

Leveling kit now available for Chevy Colorado, but not yet for GMC Canyon

In various bits of news this year concerning the Chevrolet Colorado and GMC Canyon pickups, we kept hearing about a front leveling kit. GM Authority found a few details in early order guides in January. In February, the kit came up in relation to the Canyon's AT4 Off-Road Performance Package, and again with AEV's upgraded Colorado Bison. After three months of waiting, GMA has more info. The kit eliminates the trucks' raked stance by raising the front by one inch, using an electro-coated upper spacer and a polyurethane lower spacer in order to maintain the proper suspension geometry. Installation is a bolt-on job with low-profile nuts, but the task will require a spring compressor. Fitted properly, the kit doesn't void GM's new vehicle warranty on the Colorado. Why do we only mention the Colorado? Because for some reason, the kit isn't available for the Canyon yet as a standalone component; the GMC stays raked without one of the aforementioned option packages. For Chevy, the leveling kit is compatible with any trim in four-wheel drive except the ZR2. It cannot be installed on two-wheel-drive trucks, nor any truck wearing wheels that are 20 inches or above. The kit is available now, ordered through any Chevy dealer for $150. There is a treat in store for GMC buyers, though, but it requires spending a lot more money. GM Authority discovered that the 2021 Yukon will offer the brand's first illuminated emblem. Priced at $475 as a dealer-installed option, a backlit glow will show off the GMC logo in the grille. The brand makes the logo in red and black, it's thought the red logo will get the nod, at least at first. Only the front logo earns the spotlight, not the one on the tailgate. GMA says the tchotchke will be available on all four trims when the new full-size crossover goes on sale in a few months.
