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 Ford Escape hybrids vs other crossover fuel sippers: How they compare on paper

Along with a new generation of Escape, Ford also reintroduced the world to the 2020 Ford Escape Hybrid. And if that weren't enough, Ford is adding a plug-in hybrid version. This is a sign of the times: people are more crossover crazy than ever, but are also seeking ways to use less fuel, whether it's for environmental or purely money-motivated reasons. The Ford hybrids aren't the only fuel-efficient compact crossovers on the market. They will be going head-to-head with conventional hybrids including the 2019 Kia Niro, 2019 Nissan Rogue Hybrid and 2019 Toyota RAV4 Hybrid. There are other plug-in hybrids including the 2019 Subaru Crosstrek PHEV, 2019 Mitsubishi Outlander PHEV and the plug-in version of the 2019 Kia Niro. There are even a couple diesels in the form of the 2019 Chevy Equinox and 2019 GMC Terrain. So we've rounded up the details on all these crossovers to see who leads and lags in criteria such as power, fuel efficiency, space and price. Check out all their details below. 2019 Subaru Crosstrek Hybrid View 68 Photos How do their engines and fuel economy compare? Conventional Hybrids and Diesels Let's face it, if you're buying one of these crossovers, one of the things that matters most to you is just how frugal with fuel they are. We'll start off with the conventional hybrids and diesels, and the clear victor is the Kia Niro, which in base FE trim, manages to hit 50 mpg combined. This is thanks to it sharing its powertrain with the Hyundai Ioniq, the Hyundai equivalent of the Toyota Prius. Buyers should take note that only the FE returns such high fuel economy. The LX and EX drop to 49 mpg, and the S Touring and Touring get 43. Even then, the least efficient Niro is the most efficient of the normal hybrids and diesels. It is nearly the least powerful, though, with 139 horsepower. Just behind it is the Toyota RAV4 Hybrid. It delivers 40 mpg combined, and it has an ace up its sleeve: it comes standard with all-wheel drive. Every other vehicle in this powertrain group has front drive standard, and the Niro isn't available with all-wheel drive at all. If that weren't enough, the RAV4 Hybrid also boasts the most power at 219 horses. While we can't say anything about Escape Hybrid fuel economy, we do know that it will make 198 horsepower, which is close to the class-leading RAV4. The least powerful of these is the Equinox and Terrain, and they return the worst fuel economy at 32 mpg.

2018 GMC Terrain Drivers' Notes Review | Summon the Druids, it's a better Equinox

We've had plenty of time in the all-new Chevrolet Equinox, testing it with all three of its available turbocharged four-cylinders: the 1.5-liter, the 2.0-liter performance upgrade and the diesel fuel economy upgrade. Finally, however, we get a turn behind the wheel of its brother from a different corporate mother: the 2018 GMC Terrain. This duo is certainly one of the most disparate pairings in GM's long badge-engineering past, with virtually no visual similarities inside and out. They're even less similar than the last Equinox-Terrain, which themselves were a far-cry from the Blazer-Jimmy days. They're largely the same under the skin, however, including their selection of engines. For the 2018 Terrain, we sampled the 1.6-liter four-cylinder turbodiesel good for 137 horsepower and 240 pound-feet of torque. It's an unusual powertrain to be sure, as no other compact crossover SUV in this country offers one (though Mazda has been threatening to do so for years now), but boasts an EPA-estimated fuel economy rating of 28 mpg city, 39 mpg highway and 32 mpg combined with front-wheel drive. It's basically the same with all-wheel drive. The as-tested price of the SLT Diesel was a rather hefty $39,605. It did, however, have most options, including the Infotainment Package II and Driver Alert Package II that together include all the extra entertainment and safety gadgets. Contributing Editor James Riswick: Let's be honest, the main difference between the 2018 GMC Terrain and its Equinox sibling is the way they look. As such, I can definitively say I prefer the Terrain. It's far more cohesive and better proportioned than the rather dumpy Equinox. It also avoids the garish over-adornment of the last Terrain even if the floating roofline D pillar has passed its expiry date. I think the interior looks better too. As for the way it drives, the 2018 Terrain demonstrates great improvements from one generation to the next. The steering in particular is greatly superior in its feel and feedback. Body motions are also kept nicely in check. Is it a Mazda CX-5 or Ford Escape beater? No, but it's far more confidence inspiring now. So that's the good. Now, the extremely bad. This diesel engine vibrates so much I can't imagine anyone taking one for a test drive and choosing it over the 1.5-liter gasoline turbo. You feel it through the wheel, the pedals and the seat of your pants constantly. It's particularly bad when stopped and even present when just cruising on the highway.
