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? Read More >

Between Mopar’s 707-horsepower Hellcat engine and Honda’s 306-horsepower turbocharged 2.0-liter from the Civic Type R, the crate engine gods have smiled on both axles today.

Like Mopar, Honda took advantage of this week’s SEMA show in Las Vegas to announce the availability of the front-drive monster’s engine in standalone form. No doubt this news immediately inspired visions of the cobbled-together HR-V Type R you really wanted, but be warned. This engine comes with an asterisk. Read More >

For five years now, Mazda has hinted, then promised, then reassured us that a rotary-powered sports car will return to the company’s lineup, ready to fill a spot left vacant by the departing RX-8 in 2012.

We’re still waiting and, Mazda now informs us, we’ll be waiting quite a bit longer. While the cylinderless gasoline engine holds promise as a range-extender in electrified vehicles (something powertrain chief Mitsuo Hitomi feels is a definite future use for the powerplant), that’s not something Wankel fans want to hear. They want to spin that engine up to eleventy billion rpm and drop the clutch.

It’ll happen, says Mazda’s senior managing executive officer, Kiyoshi Fujiwara, but something’s cropped up that pushed the rotary’s return to the back burner. That thing is the company’s gasoline compression ignition engine, the Skyactiv-X. Read More >

Think of the Ford F-150 pickup and one’s mind immediately turns to an excellent pair of EcoBoost V6 engines with 2.7 and 3.5 liters of displacement. And why wouldn’t you? Together, Ford’s twin-turbocharged V6 twins make up three-quarters of the model’s engine share. These beauties are the last word in full-size pickup torque, though the 2.7-liter is a wanderer that finds deserving homes in such models as the Ford Edge, Lincoln MKX, and Ford Fusion Sport.

For 2018, both EcoBoost engines see some refinements, but buyers of F-150 XL and XLT pickups won’t see either if they leave those option boxes unchecked. In a bid to increase fuel efficiency across the lineup, 2018 sees the introduction of a naturally aspirated 3.3-liter V6 in low-rung trims, replacing the previous 3.5-liter unit.

There’s no shortage of technology at work with the new 3.3, but it can’t match the fuel economy of the closest available engine upgrade. Read More >

Last week brought quite a flurry of excitement for eager Jeep Wrangler aficionados. The long-awaited next-generation JL model has steadily revealed its secrets in dribs and drabs, but last week’s National Highway Traffic Safety Administration filing appeared to reveal one of the biggest nuggets to date — a horsepower figure for the model’s 2.0-liter turbocharged “Hurricane” four-cylinder.

368 horsepower. Even from a unit expected to arrive with power in the neighborhood of 300 hp, this figure came as a shock. 368 hp isn’t “in the neighborhood” — it’s eight blocks over, past the train tracks, and in a better part of town.

Well, to all of you anticipating a real screamer of a Jeep, it’s time to hold your breath once again. Fiat Chrysler Automobiles has updated its NHTSA filing. Read More >

Porsche is apparently seeking 200 million euros — or $234 million — in damages from its Audi stablemate over the costs associated with using its emissions cheating diesel engines. According to reports, Porsche has already issued its claim to Audi and the wheels of justice have been set in motion.

With no verified sources or official word from either automaker, the news is more than just a little strange considering both manufacturers are part of Volkswagen Group. However, Audi did supply both Porsche and Volkswagen with defeat device-equipped 3.0-liter V6s for use in various models. One of those models was Porsche’s Cayenne, and sales of the TDI variant were shelved as the scandal raged. Read More >

Did you hear the news? Every automaker worth its salt will switch to electrified, fully autonomous vehicles yesterday.

Bored yet? Very likely so, but the people laying out money for cars still have a say in what vehicles automakers produce, and for high-end buyers, prestige doesn’t necessarily come wrapped in the latest technology from the pages of Wired. Big-money buyers want big power and, while that increasingly means the latest in twin-turbocharged, downsized wonderengines, it isn’t always so.

Audi can’t wait to challenge Mercedes-Benz, BMW, and Jaguar in the premium electric car race, but there’s no way its customers would agree to the disappearance of a proper eight-cylinder gasoline engine, claims the brand’s technical development chief. Read More >

Want a six-cylinder engine?

Don’t buy a two-door Mercedes-Benz S-Class.

For the 2018 model year, Mercedes-Benz will offer a S450 sedan with a twin-turbocharged 3.0-liter V6. It’s not underpowered. 362 horsepower produce a claimed 0-60 miles per hour time of 5.1 seconds.

But sometimes, every now and then, in a handful of remaining instances, Mercedes-Benz evidently believes there is no replacement for displacement. The Mercedes-Benz S-Class coupe and cabriolet?

V8s and V12s only, thank you very much. Read More >

Volkswagen of America confirmed last evening via email the alteration of the Passat and Beetle engine lineups for the 2018 model year.

In examining updated EPA mpg figures for the 2018 model year — as one does — we noticed a curious change. The 2018 Volkswagen Beetle Dune achieves slightly better highway fuel economy, 34 mpg, than the non-Dune 33-mpg 2018 Volkswagen Beetle.

By the by, after posing a handful of questions to Volkswagen of America spokesperson Mark Gillies, TTAC learned that the 1.8-liter turbocharged four-cylinder that served as the base engine in the Volkswagen Passat and Volkswagen Beetle from 2014-2017 is out. It gives way in the 2018 Passat and Beetle to the second-generation Tiguan’s EA888 Gen3B 2.0-liter turbocharged four-cylinder.

The result? Better fuel economy and more torque. Read More >

As Ford prepares to launch the refreshed 2018 F-150 with a thoroughly updated engine lineup, Blue Oval product planners expect 2017’s engine selection to continue. That means the 5.0-liter V8, while mildly upgraded for 2018, will be found under the hood of only one in four 2018 F-150s.

The transition has been a rapid one. Twin-turbocharged EcoBoost V6s were surprisingly effective when, in early 2011, 35 percent of F-150 buyers made the leap from conventional naturally aspirated powerplants. Three years later, when Ford was planning to expand the F-150’s EcoBoost lineup with a less costly 2.7-liter variant, Ford expected 56 percent of F-150 buyers to choose one of the turbocharged units.

Heading into 2018, Ford’s truck marketing manager Todd Eckert tells Automotive News that the 2.7-liter EcoBoost will be the most popular F-150 engine followed by the 3.5-liter EcoBoost. Together, they’ll claim 65 percent of all F-150 sales, leaving 10 percent for the new entry-level 3.3-liter, and roughly 25 percent for the five-point-oh.

So how many V8 engines is that? Read More >

Healthy competition lowers the price of consumer goods, the economists tell us, but it also raises torque ratings. Nowhere is this more apparent than among the Detroit Three automakers, with Ford, General Motors and Fiat Chrysler Automobiles locking horns, crossing swords (keep it clean…), and firing arrows at each other in a heavy-duty pickup war that’s only heated up in recent years.

It comes down to stump-pulling, gravel-hauling, trailer-towing twist. In 2015, the Ram 3500’s 6.7-liter Cummins inline-six turbodiesel topped the Ford F-350 SuperDuty’s 6.7-liter turbodiesel V8 by 5 lb-ft of torque — 865 to Ford’s 860. This clearly couldn’t stand, so for 2017 Ford upgraded the Power Stroke’s torque rating to 925 lb-ft, kiboshing Ram’s 2016 attempt to stay ahead with a 900 lb-ft rating.

With 2017 came further aggressions. This year saw GM pulling ahead to second place with its 6.6-liter Duramax V8, now upgraded to 910 lb-ft, knocking Ram down to third place.

Well, FCA’s having none of it. Just a day after Ford’s unveiling of a newly powerful second-generation 2.7-liter EcoBoost V6 and 5.0-liter V8, Ram fires this salvo: a Cummins with more grunt than any other rival. Read More >

Screenshots of preliminary information added to the Fiat Chrysler Automobiles dealer network computer system suggest the next-generation Jeep Wrangler, due for a late-November reveal, breaks with tradition in more than a few ways. The largest break involves how the 2018 Wrangler puts its power down to all four wheels.

The dealer system images, shared by JL Wrangler Forums, show the Wrangler adopting a Selec-Trac full-time four-wheel-drive system, among other drivetrain details. Is this a goodbye to the manly transfer case lever? Read More >

Mazda announced on August 8th what had long been rumored. The small Japanese automaker has successfully overcome the remaining issues which held at bay mass production of gasoline compression ignition.

Essentially, Mazda’s Skyactiv-X engines, due first in the next-generation 2019 Mazda 3, is intended to bring diesel-like ignition to small, supercharged four-cylinder engines, along with diesel-like fuel economy. However, the gas-fired Skyactiv-X engines will be wildly cleaner than diesel powerplants. Mazda has said in the past that these HCCI engines will likely limit the need for continuously variable transmissions. We also learned, with Mazda’s latest pronouncement, that the company’s Skyactiv-X engines will be significantly torquier than their Skyactiv-G predecessors.

If Mazda can live up to its pronouncements — the company says the engines are “still under development and figures are subject to change” — it’ll be a win for both the environment and driving enthusiasts. And because Mazda also claims a 20-30-percent improvement in fuel efficiency, it’ll be a win for your bank account, as well.

We wanted to see exactly where Mazda’s alleged fuel savings will put Mazda’s current products on the EPA’s miles per gallon scale, so here are the results of some quick math. Read More >

There’ll still be spark ignition available, but Mazda doesn’t expect you’ll get a whole lot of use out of it. With its just-revealed Skyactiv-X engine technology, the gasoline-loving automaker has added a new way of making power to the automotive realm: the compression ignition gas engine.

It’s something we’ve known about for a while, but today saw its confirmation. Mazda’s Skyactiv-X engine, bound for its vehicle lineup in 2019, adopts technology forever associated with diesel engines and combines it with a lighter, much cleaner fuel. Apparently, going green needn’t require batteries and AC motors. Read More >

If you were among America’s 1.4 million new vehicle buyers in July 2017, there’s a 99-percent chance your new vehicle requires fuel. Although the vehicles that run off the electric grid are linked to $7,500 government tax credits, they form barely more than half of one percent of the U.S. new vehicle market.

Mazda, you’ll recall, doesn’t sell any electric vehicles in the United States. Mazda doesn’t sell any vehicles with a plug. Mazda doesn’t even sell any hybrids.

So it’s not surprising that Robert Davis, former Mazda USA senior vice president of operations who’s now in charge of special assignments, candidly laid out the case for the internal combustion engine yesterday at the CAR Management Briefing seminars in Traverse City, Michigan.

“The internal combustion engine has a strong future role in transportation,” Robert Davis says. Read More >
