Earlier today, we found out that the 2019 Ram 1500 will be offered with a mild hybrid option dubbed eTorque. Official fuel economy figures are not out yet, but FCA estimates the hybrid system should show around a 10 percent improvement over current figures. The system employs a motor-generator driven off the crankshaft that is similar to the GM BAS system in some ways.

The novel part of the Ram system is that it does not require liquid cooling on the V8 version and is instead air-cooled, which should reduce costs significantly.

Thus far, the North American International Auto Show has been a truck festival – more specifically, a green-truck fest. Ram showed a hybrid 1500. Ford revealed their V6 diesel. Chevrolet surprised with an inline-six diesel. Clearly the Big Three are looking at the calendar, with a big red circle over the 2025 CAFE standards looming like a dark cloud.

Achates Power, a fourteen-year-old startup from San Diego, has a different idea. By combining a variety of existing technologies – some of which date from before World War Two – they have developed an engine that they expect to meet 2025 fuel economy standards, emissions standards, and most importantly, the performance standards of light-truck buyers.

How does 37 mpg sound in a half-ton truck? That’s on gasoline. The Achates engine can also manage 42 mpg in the same truck running on diesel.

The first Bullitt go-round was a 2001 attempt to upgrade the Mustang GT with a modicum of extra power and a styling nod to an old movie that couldn’t be more forgettable, were it not for a stellar chase sequence. The 2001-2002 Mustang Bullitt, however, couldn’t do anything about its facelifted 1990s sheetmetal, which hardly asks, “Are you going to San Francisco?”

It was the fifth-generation Mustang’s retro design that proved a far more suitable canvas for Ford’s performance brush. Endowed with a more generous helping of brawn, the 2008-2009 Bullitt was a fitting homage to a certain Dark Highland Green ’68 Mustang 390. Still, all good things must come to an end. Or do they?

If you’ve heard rumors recently, consider this a confirmation. The Bullitt is back, just in time for the 50th anniversary of the Steve McQueen flick that made chassis-bending jumps popular a decade before the Duke boys. Driven onto the Cobo Center stage in Detroit by McQueen’s granddaughter, Molly McQueen, the Sunday night reveal of Ford’s turtleneck-and-sport-coat ‘Stang was a pleasant distraction from the automaker’s incessant future-speak.

General Motors has recently filed a patent that could point to the future of the company’s high-performance offerings, including the C8 Corvette.

After 18 months in review by the United States Patent and Trademark Office, documents published on October 24, 2017, reveal GM has been granted a patent for an internal combustion engine with elevated compression ratio and multi-stage boosting.

The document describes a propulsion system made up of a high compression internal combustion engine that uses a low-flow supercharger in combination with a high-flow turbocharger, linked to “one or more electric motor/generators.”

It gives us an interesting look at how GM engineers plan to continue producing obscene performance cars like the Corvette ZR1 and Camaro ZL1 1LE in a world of increasingly stringent emission regulations.

Volkswagen, most recently seen lecturing European governments on the need to ditch the diesel subsidies that, until recently, made it the continent’s most popular fuel, has a bad case of timing.

Just a day after Volkswagen Group CEO Matthias Müller not-so-subtly touted his company’s newfound green bona fides, telling a German newspaper, “We should question the logic and purpose of diesel subsidies,” another diesel-related scandal broke. On Tuesday, Germany’s automobile regulator, KBA, issued a recall of VW’s top-end diesel SUVs.

The reason? Undeclared defeat devices, apparently designed to make the late-model 3.0-liter vehicles run cleaner while undergoing emissions testing. If this doesn’t sound familiar, you’ve been dead for the past two years.

It’s not just scorched rubber that’s responsible for the clouds of white smoke surrounding some Ford Focus RS models. The model’s high-output 2.3-liter EcoBoost four-cylinder, credited with turning the staid Focus 5-door into a performance hatch worthy of fanboy lust, seems to have a serious flaw.

Numerous complaints of white exhaust smoke seen during cold startups has forced the automaker to admit there’s a problem with the FoRS. The 2.3-liter is not electing a new Pope, as TTAC’s Matthew Guy quipped this morning — it’s burning coolant.

It’s become a trend. The annual who’s-got-more-twist competition between Ford and Ram is now so regular, so expected, we can even predict by exactly how many foot-pounds the new victor will reign.

Five lb-ft.

Recently announced by Ford, the 2018 Super Duty line’s 6.7-liter Power Stroke diesel V8 wrestles the torque crown back from the Ram Heavy Duty, which had held it for just a year. The exact same scenario played out in the leadup to that particular upset. At this pace, it shouldn’t be too long before American buyers are laying down greenbacks for twist numbers in the four-figure range.

We know from spy photos that the refreshed 2019 Jeep Cherokee will (finally) ditch its awkward stacked headlamps, instead adopting a conventional setup that doesn’t make the vehicle look like it’s squinting. The look is more in keeping with the second-generation Compass and Grand Cherokee.

Expect very little outcry over this sensible and long overdue decision.

However, an updated fascia isn’t the only change in store for 2019. The midcycle revamp also brings a new powerplant sourced from the 2018 Jeep Wrangler, documents show.

Volkswagen’s 3.0-liter diesel V6 isn’t returning to the U.S. anytime soon. After forking over roughly $25 billion in the wake of its diesel deception, the company’s not exactly enthused about getting back into the compression ignition game. But that doesn’t mean buyers aren’t.

Europhiles with a penchant for low-end torque can still get their hands on a diesel Volkswagen or Audi SUV that meets federal emissions standards. And, thanks to new discounts, they’ll stand to save some money.

What is it about the new crop of vehicles? It’s great that the”cheerful” phase in automotive styling is over (the demented visage of those old Mazda 3s still haunt my nightmares), but what we’re left with, at least in the passenger car segment, is enormous, angry grilles or, in the case of the 2018 Ford Mustang and next-generation Mercedes-Benz CLS, a kind of sad face.

Why the droopy eyes, Mercedes?

Whatever the reason, the automaker is bringing more than a questionable front end treatment to the table with its third-generation CLS. The sedan that started the four-door coupe craze (which then jumped ship to the SUV segment) adopts a host of changes for 2019, not the least of which is a new engine that should have both purists and futurists smiling.

All hail the inline six.

Nissan’s luxury division isn’t saying it’s the next-generation QX50, but everything we know about that model and its revolutionary (and potentially risky) engine points to one conclusion.

For now, and until the vehicle’s unveiling at the L.A. Auto Show on November 28th, Infiniti simply refers to it as an “all-new model” — one boasting “world-first” technology. The technology’s no mystery, as after two decades of development Infiniti plans to launch a 2.0-liter variable compression gas engine. Expect class-leading interior volume, the automaker tells us.

We’ve mused on Infiniti’s Variable Compression Engine in the past, calling it everything from a chameleon to the holy grail. Its killer app? The ability to changes the distance the pistons travel in their cylinders by as much as 6 mm, or about a quarter of an inch.

Why is this important? Because it is, arguably, the first major change to the workings of a internal combustion engine in more than a century.

Underpowered. Not as refined as the competition. Fantastic looks. Excellent handling. It’s hard to find a review of the Mazda 6 midsize sedan that doesn’t include at least two of these observations.

For 2018, Mazda’s hoping the first criticism goes the way of disco (or of the midsize sedan segment). Ahead of its November 29th debut at the L.A. Auto Show, the zoom-zoom brand is letting everyone know that buyers enamored with the 6’s flowing lines needn’t suffer from mediocre grunt. Mazda’s blowing the 6’s 2.5-liter four-banger for the upcoming model year.

Newly restyled for its 2017 debut, the fifth-generation Land Rover Discovery rock crawls into 2018 much the same, save for pricing, new standard and available content, and the wider availability of a powerplant with a bad global reputation.

Not to say that Jaguar Land Rover’s 3.0-liter diesel V6 is a bad motor — rather, that all oil-burning engines have taken an image hit since Volkswagen’s recent naughtiness. Still, Jaguar Land Rover is enjoying surprising success with its diesels in the United States, so it’s not entirely surprising to see a powerplant known for stump-pulling torque setting up shop in another off-road focused model.

There’s nothing quite as uncertain as that little number staring at you from the window sticker of a new vehicle. It’s two digits long (unless you’re fabulously rich), followed by the word “combined.” We’re talking, of course, about the Environmental Protection Agency’s fuel economy rating, which often turns out to be an impossible-to-reach goal or — if you’re lucky — a lowballed figure.

Back in the days of lapels and flares, the hot gas mileage action was found in the compact and subcompact class. Economy cars, after all. Well, people these days prefer driving a vehicle that seats at least five adults in comfort while towing a boat and hauling 65 pounds of kid’s toys and a dog in the rear cargo area. With the heyday of the cheap little car long gone, the (fuel) economy battle rages anew among the largest, and most lucrative, vehicles on the road.

So, do you believe the EPA when it says the massive 2018 Ford Expedition gets 20 miles per gallon combined?
