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.

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.

2015 Cadillac ATS Coupe First Drive

Save for a few years of its century-plus existence, Cadillac has offered its unique brand of American elegance in two-door, fixed-roof bodystyles. Most of these cars were big, floaty barges, of course, though its most recent offering was the wedge-shaped CTS Coupe. But whereas the CTS Coupe was a statement car – angular and severe, with somewhat limited appeal except to design snobs and provocateurs – the ATS Coupe represents a return to form for Cadillac, with a proper three-box (engine-cabin-trunk) body and a slightly lower price point that should broaden its appeal among a larger swath of the market. Generally speaking, the 2015 ATS Coupe is a two-door version of the sporty ATS Sedan, though, surprisingly, the only common exterior components are the hood, headlamps, and sundry trim pieces on the front fascia (which features a slightly larger grille, a wider lower air intake, and the redesigned, laurel-less Cadillac crest). Even the mirrors are different. The body stretches 0.8 inches in length and 1.4 inches in width, the roof is 1.1 inches lower and the rear windscreen slopes at a flatter, sleeker angle. Interestingly, the windowsills are actually quite a bit lower, further slimming the car. Thanks to its 0.8-inch wider front and rear wheel tracks as well as more tumblehome in the C-pillar area, the coupe sits lower and looks more planted than the ATS sedan, particularly from the rear three-quarter view. Filling the wheel wells is a family of slick 18x8-inch wheels, with 18x9-inchers coming on the rear axle of performance models. Even if all those changes haven't resulted in a wholly new look the way the CTS Coupe departs from its sedan progeny, the ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. And for that, Cadillac deserves mighty praise. The ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. It is a proper coupe, of course, and as such is saddled with the expected limitations that accompany modern two-door packaging, notably rear seat access and limited rear headroom. Since the floorpan is common to both bodystyles, rear legroom is the same as the sedan's, though headroom shrinks a considerable 1.8 inches, making it hard for even average-sized adults to sit back there without their heads touching the window glass.
