GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:      

2020 GMC Sierra gets small price bumps, package discounts and tweaks

A couple of months ago we covered a brace of changes GMC made to the 2020 Sierra 1500. Those included availability of the 2.7-liter turbocharged four-cylinder with 310 horsepower and 348 pound-feet of torque, the 5.3-liter V8 getting the 10-speed automatic transmission, the CarbonPro Editions debuting for AT4 and Denali trims, and a new bed view camera. But GMC has made a few more smaller changes throughout, as GM Authority found, part of a detailed overhaul among GM's pickup lines that's already changed trim names, trim volume, and prices on the Chevrolet Canyon and GMC Colorado. We'll start with MSRP adjustments on the 2020 Sierra: 4WD drivetrains in SLT, and the AT4, and Denali trims that only come in 4WD, see a price increase of $200. There are also more MSRPs to consider this year, with a handful of new Elevation models filling price gaps.  The only changes inside are AT4-logoed all-weather floor liners that come standard for that trim, and adaptive cruise control joining the Driver Alert Package II available on the SLT, AT4, and Denali trims. Speaking of packages, the Value Packages represent truth in advertising. The new base-model Sierra Sierra Value Package costs $860 to combine the Convenience Package and Trailering Package. Those two cost $1,640 when ordered separately. Sticking with the base trim, the Chrome Exterior Package disappears because the chrome bumpers it added are now the standard finish. Black bumpers front and rear can be ordered at no charge, and the 17-inch Bright Silver painted aluminum wheels can be ordered alone. One trim up, the SLE Value Package lumps Convenience and Trailering, too, but it only costs $380, which is $15 less than the Trailering Package by itself. The Elevation Value Package gets cut by $1,330 to $585. On the AT4 trim, GMC dropped the price of the CarbonPro Package from $1,060 to $560, and the Premium Package comes down by $500 as well. The same $500 discount applies to the SLT Premium Package. The new 2.7-liter turbocharged four-cylinder is the optional engine on the base, SLE, and Elevation trims, saving $235 on the first trim and $395 on the other two compared to ordering the standard 4.3-liter EcoTec V6. Smokey Quartz Metallic exterior paint is expected to disappear come Q2. Two new wheels enter the range in the upper reaches, one being a 20-inch Carbon Grey painted rim available on the AT4 CarbonPro Edition.
