A document containing official horsepower and torque numbers for General Motors’ new 6.6-liter V8 Duramax turbo-diesel was found buried on the GM Powertrain website — before the company quickly deleted it.

Chevrolet has lifted the curtain on its next-generation Equinox, revealing a host of technological and styling updates for a long-running model that had grown long in the tooth.

The changes coming for the 2018 model year put the Equinox as a proper compact SUV, as the slimmed-down model sheds significant weight and adopts a trio of turbocharged four-cylinders. Going out on a limb in the red-hot market segment, Chevrolet plans to offer a diesel.

Ford Motor Company stuck a “for sale” sign on Jaguar Land Rover as the world spiraled into the 2008 financial crisis, but its engines still beat within many of the British automaker’s models.

That will soon change, as the Tata Motors-owned company continues its rollout of in-house engines designed to reduce its dependence on other companies.

At the dawn of recorded history, a German auto manufacturer unveiled a concept vehicle and promised North America — then weighed down by the oppressive bulk of towering ice sheets — a new midsize SUV.

Okay, that was only 2013, but it seems that the Volkswagen Teramont (VW hasn’t confirmed the name) has been in development for eons. Billed by some as the automaker’s make-or-break model in the U.S., the Teramont is a seven-seat SUV that borrows its design language from the CrossBlue concept. The automaker’s Chattanooga, Tennessee assembly plant will give birth to the model next year.

Now we know what lies under its hood.

A Ford dealer has leaked power figures for the upcoming 2017 Ford F-150 Raptor, showing what Blue Oval engineers can do with a 3.5-liter Ecoboost V6.

According to dealer product document posted on Ford Raptor Forum, the high-output version of Ford’s upgraded twin-turbo six will make 450 horsepower and a whopping 510 pounds-feet of torque.

Bosch, the creator of the horsepower-boosting water injection system in the BMW M4 GTS, will now offer the technology to any automaker that wants it.

Spraying distilled water vapor into an engine’s combustion chamber has an added bonus of greatly increasing fuel efficiency — meaning Bosch might have a lineup at its door when the system enters mass production in 2019, Autocar reports.

Low-octane gasoline. It was great for the detuned boat anchors found under the hoods of 1970s Malaise-era barges, because you weren’t having fun, anyway.

The future of gasoline-powered vehicles is all about high-compression engines and ever-stricter environmental regulations, meaning gasoline with higher octane than today’s pumps can provide could be on the horizon.

Ford Mustangs are hot. They’re hot in America, and they’re unusually hot in Europe, too. People like driving them, and they sure as hell like talking about them. But it’s no secret that Ford thinks the Mustang isn’t hot enough, given its third-place standing in the pony car horsepower wars.

We’ve heard that Ford wants a Mustang to challenge the Dodge Challenger Hellcat and Chevrolet Camaro ZL1, but a new report claims that the next Shelby GT500 will beat them both.

Infiniti has a revolutionary new engine in the works that’s both a high-compression mileage-maker and a low-compression pavement burner, giving drivers the option of being lean or mean at any given time.

The world’s first variable compression engine, dubbed the VC-T, ate up 20 years of design work before Infiniti went public with its achievement. The automaker plans to unveil the revolutionary engine next month, at the Paris Auto Show.

After ridding itself of the limp carcass once known as Rover over 15 years ago, BMW — the former parent of Land Rover — looks like it might provide V8 motivation to future Land Rover and Jaguar models.

According to Automobile, BMW wants an engine partner in order to amortize development of an upcoming 4.0-liter twin-turbo V8, and Jaguar Land Rover could be that partner.

Volkswagen’s emissions scandal gave oil burners a bad name, but Mazda isn’t ditching its plans for a diesel roll-out in North America.

The automaker has an internal timeline for a stateside launch of Skyactiv diesels that will meet stringent U.S. pollution regulations, Automotive News reports.

Ford clearly low-balled its power figures when it issued a sneak peek of the second-generation 3.5-liter EcoBoost V6 back in May.

The newly massaged engine, which will get its debut in the 2017 F-150, was thought to gain 30 pounds-feet of torque. Now, Ford claims the mill will gain 10 horsepower and 50 lb-ft, for a total of 375 hp and 470 lb-ft — a torque figure that beats the F-150’s V8-powered competition.

General Motors wants better performance from its boosted engines, so it headed to the patent office with a design for a new two-stage turbocharger — one that eliminates the drawbacks of the existing setup.

According to a document published by GM Inside News, the General filed the patent on May 19. The design (mated to a four-cylinder engine) isolates the low-pressure and high-pressure turbines, calling on one or the other (but not both) at different engine speeds and loads.

Ford’s comparing itself to the Germans again, but this time the vehicle isn’t a Granada, and the disco era isn’t still raging.

The automaker just announced it boosted the output of the 2.7-liter EcoBoost V6 in the 2017 Fusion Sport, keeping horsepower levels the same while adding an extra shovelful of torque.

GMC’s got a secret, but it’s keeping it hidden under the hood of its 2017 Sierra Denali 2500HD for now.

The company released photos today of the their updated heavy-duty pickup, and made sure everyone noticed the functional hood scoop above its massive grille.
