Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

2016 Chevy Colorado and GMC Canyon recalled for opening console lids

The Basics: General Motors is recalling 9,200 examples of the 2016 Chevrolet Colorado with build dates between August 25, 2015 and September 24, 2015, and the 2016 GMC Canyon manufactured from August 28, 2015 to September 24, 2015. In total, 8,763 of these pickups are in the US, and the rest are in Canada or Mexico. The Problem: The console compartment lid could open in a crash, and the items inside the storage compartment might hit occupants during the accident. This fault puts the pickups out of compliance with the Federal Motor Vehicle Safety Standard. Injuries/Deaths: None reported. The fix: Dealers will replace the console compartment door latch assembly with an improved part. If you own one: GM has not yet told NHTSA when the repairs for these pickups begin. Related Video: RECALL Subject : Console Door may not Fully Latch/FMVSS 201 Report Receipt Date: DEC 01, 2015 NHTSA Campaign Number: 15V807000 Component(s): LATCHES/LOCKS/LINKAGES Potential Number of Units Affected: 8,763 All Products Associated with this Recall Vehicle MakeModelModel Year(s) CHEVROLET COLORADO 2016 GMC CANYON 2016 Details Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2016 Chevrolet Colorado trucks manufactured August 25, 2015 to September 24, 2015, and GMC Canyon trucks manufactured August 28, 2015 to September 24, 2015. The affected vehicles have a console compartment lid latch assembly that may fail to keep the compartment door closed in the event of a crash. As such, these vehicles fail to comply with the requirements of the Federal Motor Vehicle Safety Standard (FMVSS) number 201, "Occupant Protection in Interior Impact." CONSEQUENCE: If the console compartment door does not remain closed in a crash, the contents stored in the console may strike the vehicle occupants, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will replace the console compartment door latch assembly, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 16370.
