With General Motors aiming for a May 18th restart of North American vehicle production, powertrain components, in some cases, need a head start. That’s why May 11th will be the first day back to work for many employees of GM’s St. Catharines Propulsion Plant, home to much-used V6 and V8 engines, as well as a transmission.

The gradual return to work ahead of GM’s restart date comes after the Canadian labor leader Jerry Dias expressed concern over workplace safety. (Read More…)

The revamped, full-size Chevrolet Tahoe and Suburban and their GMC Yukon/Yukon XL twins gain significant length, interior volume, and creature comforts for 2021, but extra MPGs seem to be in short supply.

The vehicles are now even larger than their predecessors, are still heavy, and carry identical V8 engine displacements, so no one should have expected Prius fighters. Still, the changes in fuel economy are worthy of note. (Read More…)

The Nissan Rogue compact crossover might not be everyone’s idea of a fun ride, to say the least, but it’s a crucial product for the automaker that builds it. By far Nissan’s best selling vehicle in North America, the Rogue is key to the automaker’s comeback hopes.

Maybe comeback is too strong a word…

Fiscal stabilization. Yeah, that’s the ticket.

As production schedules and launch dates suffer from the ongoing coronavirus pandemic, Nissan is readying a new generation of Rogue. Apparently we can’t expect something exciting, powertrain-wise, right out of the gate, but that doesn’t mean things won’t change under the 2021 Rogue’s hood. (Read More…)

Despite the switch to low-sulfur fuel and ever more stringent emissions regulations around the world, compression ignition technology still gets a bad rap, tarnishing the remaining crop of diesel engine offerings despite their fuel economy advantages.

In the world of heavy duty pickups and large commercial vehicles, it’s a case of diesel or what else? Electric motors powered by battery banks the size of a refrigerator warehouse? Gotta use what works.

Diesel engine maker Cummins sees plenty of life left in the technology, and believes better is possible. If gasoline engines can shut down cylinders at will to conserve fuel, why not oil burners? (Read More…)

While it remains to be seen whether the revamped 2021 Cadillac Escalade enters production on schedule this summer, other details about General Motors’s loftiest SUV have begun leaking out.

One item concerns the vehicle’s price, while the other tidbit might interest those who have a difficult time separating their eco-consciousness from their economic reality. (Read More…)

It’s a car-heavy day here at TTAC, and thank God for that. These vehicles still exist, and it seems automakers who stubbornly continue to field ’em haven’t given up on the idea of improving three-box products.

That said, it’s hard to think of a mainstream automaker that offers more choice in cars than Kia Motors, and one of its more (most?) interesting products could be due for an upgrade. (Read More…)

The current-generation Mazda 6 debuted with a shapely body that withstood the passage of time and handling attributes that elevated it above other front-drive, midsize rivals. Alas, the car dropped as the market was moving away traditional midsize sedans. Not helping its case, Mazda was slow to respond with improvements — like a turbocharged 2.5-liter four-cylinder, for example, or all-wheel drive that still hasn’t appeared.

Word is that the next Mazda 6 will correct all criticism of the current car, donning a new layout and propulsion. By the sounds of it, the next-gen 6 will be everything an enthusiast wants, but will there be anyone left to buy it? (Read More…)

We can’t tell you how the Chevrolet Trailblazer, reborn as a vastly different vehicle for 2021, drives (thanks to a first drive program scuttled at the 11th hour by coronavirus), but at least we can tell you what to expect at the pump.

As the model starts quietly trickling onto dealer lots at a time when most Americans are scared to leave the house, the Environmental Protection Agency has gotten around to testing the model’s full range. Two three-cylinder engines and two transmissions are on tap. Let’s take a look. (Read More…)

Last year’s debut of a wonderfully throwback engine was just the early Christmas present many traditional truck fans needed. Sporting an iron block, pushrods, and 7.3 liters of displacement, Ford’s new heavy duty V8 felt like the 1970s were still upon us.

Rumor has it Mathew Guy has a blueprint of one adorning his bedroom ceiling.

While a delightful addition to the world of all things American and big, the engine carrying the codename Godzilla leads us to ponder how long it can all last. (Read More…)

The unexpected and potentially under-cylindered 2021 Chevrolet Trailblazer is a vehicle you would have read about in these digital pages, had the pandemic not scrubbed a first drive event scheduled for late last week. For sure, yours truly was quite curious to see how well the model’s brace of boosted three-cylinders hauled around the tweener crossover’s modest bulk.

Alas, drive impressions are off the table as we deal with this virus thing. We’ve told you the specs already, given you a taste of what to expect from the not-quite-compact CUV and its Buick Encore GX sibling, and even revealed the EPA ratings of the latter model.

Now it’s time to hit the trail(blazer). (Read More…)

Not long ago, Subaru announced its intention to bring transmissions to Indiana. Now, Fiat Chrysler plans to replace some of its tranny-building capacity with engine production. Either way, it’s good news for the Hoosier State.

Lost in the shuffle late last week was news that FCA intends to spend $400 million converting the shuttered Indiana Transmission Plant II in Kokomo to a home for the automaker’s turbocharged 2.0-liter four-cylinder. (Read More…)

When it was rumors and innuendo, when it was delayed, when it was confirmed but unattainable, when it was launched, when it was actually under the hood of a vehicle we could drive on this continent, we’ve covered the story of Mazda’s diesel engine.

It’s a 2.2-liter turbocharged four-cylinder with a measly 168 horsepower but a stirring 290 lb-ft of stump-pulling torque. It resides not in the Mazda 6 for which it was originally intended but rather the highly acclaimed Mazda CX-5. It’s available only in the CX-5’s top-spec Signature trim, and only then at a $4,110 premium that drives the price up to an eye-watering $41,000. Its fuel economy gains are so minimal that the economic case for the CX-5 diesel is nonexistent.

And after one model year and just enough demand to help (in some small way) propel the CX-5 to yet another record sales year, the Mazda CX-5 diesel is missing. Truant. Unaccounted for.

Moreover, there’s no timetable for the CX-5 diesel’s return. (Read More…)

Given the avalanche of new domestic pickups smothering the American marketplace over the past couple of years, you’d be forgiven for forgetting about the Toyota Tundra, last revamped during the latter part of the Bush administration.

And yet, after Ford comes out with a new F-150 later this year and Nissan gets its midsize offering in order, there’ll be a new full-sizer from Toyota. (Read More…)

Turning the five-door Impreza into the lifted Crosstrek was a brilliant bit of strategy for Subaru. Sales of the jacked compact soared following its late-2012 release, rising year after year until 2018, where it managed 144,384 U.S. sales.

While the model slipped last year, Subaru is not content to leave things be. Later this year, the automaker will answer a long-standing cry from Subaru loyalists and endow the Crosstrek with moar power. (Read More…)

It started with a quip delivered in the TTAC chatroom, in which yours truly equated his computer’s speed to that of a base Chevy S-10. Naturally, any mention of low-rent vehicles from the 1980s and ’90s sent the crew into a frenzy of nostalgia.

Seems the long-gone crop of compact General Motors pickups went through a number of entry-level mills before settling on the 2.2-liter unit that carried penny-pinching buyers through the model’s second generation. Which leads us to the question: What, in your opinion, is the worst four-banger fielded by an American automaker since 1980? (Read More…)
