Chevrolet’s next-generation 2019 Silverado will be available with a turbocharged gasoline four-cylinder, making it the first full-size pickup truck to “go there.”

Displacing the same volume as Ford’s 2.7-liter EcoBoost V6, Chevrolet’s all-new motor ditches two cylinders, though it ditches even more under light loads, thanks to General Motors’ Active Fuel Management (cylinder deactivation) system.

It’s a good thing GM shaved a good deal of weight off the new truck.

The current generation of General Motors’ full-sized SUVs has become the dominant force in the segment. The six nameplates offered up by GM own seventy-five percent of America’s full-sized, body-on-frame, truck-based SUV market. The GMC Yukon and GMC Yukon XL are a big part of that dominance. Their high average transaction prices and robust sales have helped build General Motors’ fastest growing brand into a sales powerhouse.

The Yukon has always been a luxurious, yet restrained, step above the Tahoe and Suburban, and the 2015 model boosted the upscale feel with the addition of better materials like real wood. A more powerful engine further differentiated the model from its Chevy sibling. Unfortunately, the 420 horsepower 6.2 liter V8 was only available on the Denali-trimmed Yukons.

That is, until the 2019 GMC Yukon hits dealer lots. But there’s a catch.

The 2018 Jeep Wrangler JL is not the inline-six-powered, aerodynamic brick it was in years past. For the current generation model — now the only Wrangler built in Toledo — Jeep’s Jeepiest Jeep saw a host of improvements designed to lighten its curb weight, reduce aerodynamic drag, and cover more ground on a gallon of gas.

The model launched with only the 3.6-liter Pentastar V6 under its hood, aided in its fuel-sipping mission by standard stop/start and an eight-speed automatic transmission. Depending on the model and tranny, combined fuel economy rose 2 mpg between the old JK and newer JL models, and highway mileage rose as much as 4 mpg.

Finally, we now have EPA figures for the turbocharged 2.0-liter four-cylinder Wrangler.

Audi is bullish on 48-volt mild hybrids, and its Volkswagen sister division is no different in wanting to see larger batteries take some of the load off of its internal combustion powerplants.

The automaker announced Thursday that its upcoming eighth-generation Golf will offer a low-cost alternative to purely gas- or diesel-powered motoring. The mild hybrid system appearing on that vehicle, due next year as a 2020 model, will soon spread throughout the VW lineup, the automaker claims.

We’ve been talking about the Mazda CX-5 diesel for a long time, and with good reason. It’s been a long time coming. Originally promised for a U.S. introduction in the second half of 2017, a quick scan of of Mazda’s consumer website reveals no mention of a popular compact crossover with a 2.2-liter Skyactiv-D four-cylinder under the hood.

This could soon change. The California Air Resources Board has certified the engine for sale in that ecologically sensitive state, making a similar thumbs up from the Environmental Protection Agency a near certainty.

Ford was all but gloating… okay, it was gloating when it unveiled the coveted “30 mpg highway” figure for the upcoming 3.0-liter Power Stroke diesel V6 earlier this week. A full-size pickup with a 30 mpg rating? That sets it apart from all others, including the 27 mpg (highway) Ram 1500 EcoDiesel.

What the automaker didn’t mention was how much green you’ll need to shell out for a Power Stroke-powered F-150. Well, the beans are now spilled, but the product positioning seems a little odd.

Ford Motor Company claims its 3.0-liter Power Stroke diesel V6, due to appear under the hood of the F-150 starting in May, blows the competition out of the water in terms of fuel economy. The automaker now cites an EPA-estimated 30 mpg highway figure for its light-duty diesel pickup, beating Ram’s 3.0-liter EcoDiesel in pump-passing power.

The real test, however, comes later this year, when General Motors debuts its own light-duty Duramax mill — a Flint-built diesel inline-six of unannounced power and efficiency.

The popularity of the Subaru WRX and its larger-displacement STI sibling rival that of free vape coils and Monster energy drinks at a Millennial blogging event. Despite its growing age, owners and would-be buyers seem content with Subaru’s driver-focused all-wheel-drive sedan. There’s plenty of goodwill with this crowd.

As the previous-generation Impreza-based model awaits a new platform and body, it looks like buyers of the 2019 WRX STI stand to gain something that was available only in very limited numbers for 2018. More power.

For 2019, Mazda seems ready to offer two things MX-5 Miata buyers have long demanded: more power, plus a steering wheel that reaches towards the driver, instead of just tilting. These are big changes for a model where every minor detail is fussed over by engineers and enthusiasts alike.

The changes are detailed in a document — apparently originating from Mazda Canada — that details the changes coming for 2019. That doc found its way onto Reddit, which was then shared by joyful members of the Miata.net forum. How does an extra 26 horsepower sound?

It was only a few weeks ago that we told everyone a turbocharged Toyobaru would never happen. Chief engineer Tetsuya Tada said Toyota had built the car it wanted and any manner of forced induction would spoil the recipe, necessitating an entirely new platform. Meanwhile, fans of the 86 have been clamoring for more power like they all suddenly transformed into Tim “The Tool Man” Taylor. Well, they’re all about to utter a resounding uuuuaaagh?!, as the two companies may be starting work on new generation — this one with the brawny might they crave.

Rumored for production at Subaru’s assembly plant in Japan’s Gunma Prefecture, the next 86/BRZ is expected to get an uptick in displacement. So what will supposedly replace the naturally aspirated 2.0-liter?

If you’re a superfan of the 1968 film Bullitt, or maybe just of Steve McQueen, prepare to split the difference between the price of a Ford Mustang GT and a Shelby GT350.

The limited-edition 2019 Mustang Bullitt, the third generation of which bowed in Detroit in January, commands a sticker price of $47,495 after delivery, the automaker announced today — positioning it more than $11k above the GT and nearly $11k below the GT350. Of course, neither of those models offer retro-themed flourishes, nor can you order Highland Green paint.

You also get 20 extra horsepower than the GT for all that expense, which is mercifully 5 hp more than the automaker first estimated.

The radically mildly refreshed 2019 Hyundai Tucson, unveiled Wednesday at the New York International Auto Show, might not attract stares and selfies in the same way as the show’s more exotic sheetmetal, but it’ll sure draw buyers to the showroom.

Hyundai needs to collect those buyers. Amid a sales slump it hopes to remedy with an onslaught of crossovers, the compact Tucson crossover is one of the automaker’s largest meal tickets. Sales rose 31 percent, year over year, in the U.S. last month. And, while the Elantra and Santa Fe boast larger sales volumes, the Tucson has the best growth rate — sales are up 32.1 percent over the first two months of 2018.

To reward the buying public for their continued support, Hyundai has made changes to the 2019 model. Who wants a larger engine?

We can put any speculation that Toyota wants to cull its five-door Corolla iM to rest right now. The automaker has revealed an all-new 2019 model ahead of its official debut at next week’s New York International Auto Show, but with a new body and platform comes a slight name change.

The last vestiges of the defunct Scion brand, under which the iM was born in 2015, is now gone. Thus, the Corolla iM becomes simply the Corolla Hatchback. With this model, based on the European-market Auris, Toyota attempts to correct a couple of its predecessor’s glaring flaws.

In ages past, more than one nameplate could lay claim to having its own engine. Olds manufactured its own V8s for over 40 years, for example. More recently, Cadillac had its own engine too, by way of the Northstar. Yes, hindsight is 20/20 and the engine did have its challenges, but it certainly set the brand apart from its proletariat brothers.

Now, the General’s crown jewel is once again introducing its own engine, a clean-sheet design called the Cadillac Twin Turbo V8. This time, it’ll be hand-assembled and signed by the builder, just like an AMG. Ich wundere mich!

Just a week after claiming diesel technology will “ see a renaissance in the not-too-distant future,” Volkswagen Group CEO Matthias Müller said his company is prepared to bestow “practically one new electric model per month” on a world that’s apparently fallen out of love with diesel.

It’s a jarring change of tone from comments made at the Geneva Motor Show, but Müller’s not talking about next month or next year. Once the company’s MEB platform electric vehicles hit full production, he claims, expect the product floodgates to open. We’ve grown properly cynical about lofty EV promises, as well as the public’s supposed unquenchable desire for said vehicles, but Müller insists it’s the real deal.

Backing up the CEO’s claim, Volkswagen apparently has suppliers lined up to make it happen.
