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…)

2015 Jeep Wrangler Unlimited

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…)

2017 Mazda 3 - Image: MazdaMazda 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…)

2016 Mazda MX-5 Miata cutaway - Image: MazdaIf 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…)

2018 Toyota Camry Georgetown Kentucky Production line - Image: ToyotaForget hybrids. Set aside, for this moment, plug-in hybrids as well. Ignore the EV hubbub and the pie-in-the-sky hydrogen fuel cells. While you’re at it, remove turbochargers and their accompanying displacement reductions from your memory, too.

The naturally aspirated internal combustion engine has legs. The proof is in the 2018 Toyota Camry’s 2.5-liter Dynamic Force four-cylinder. With no hybrid assist, no turbos, no cord that plugs into your garage wall, and no futuristic fuel source, the new Camry 2.5-liter produces 206 horsepower and hits 41 miles per gallon on the highway on regular 87 octane.

That’s 16-percent more power 24-percent more highway mpg than the 2017 Camry’s 2.5-liter four-cylinder. With improvements in conventional, naturally aspirated, gas-fired engines occurring in such leaps and bounds, it’s no wonder Toyota has bigger plans for the Dynamic Force blueprint. (Read More…)

2018 Mustang GT, Image: Ford

As evidenced by its constantly evolving truck and SUV lineup, Ford isn’t happy printing the same horsepower and torque figures year after year. Fuel economy and cargo volume are all nice and good, and God knows American consumers love space for unnecessary, child-related crap, but performance cars aren’t dead yet. Nor is the desire for ever more rubber-shredding power.

In the hopes of satisfying those not waiting lustily for the upcoming 1.0-liter EcoSport, engineers at the Blue Oval cranked the power output of its facelifted EcoBoost and GT Mustang variants a few notches higher for 2018. The company’s also making noise about speed. Specifically, the time it takes to reach 60 mph in the 2018 Mustang GT.

Ford claims a 0-60 figure of less than four seconds when equipped with newly available Drag Strip mode — a stunning, if vague, figure that should garner bragging rights if owners are capable of replicating the feat themselves. With no exact 0-60 time given, the 2018 Mustang’s 13.5 cubic-foot trunk provides ample room for those grains of salt. (Read More…)

2017 Jeep Wrangler boasts LED headlamps.

As the next-generation 2018 Jeep Wrangler draws ever closer to its debut, an anonymous source who apparently attended a cozy, invite-only Fiat Chrysler Automobiles dealer meeting has spilled his or her guts.

The unconfirmed powertrain details leaked to JLWranglerForums shed light on what to expect under the slightly longer hood of the lighter, more aerodynamic Wrangler. It seems FCA’s battle with the Environmental Protection Agency hasn’t squashed its desire for a diesel Wrangler. (Read More…)

Ford’s German division has filed a patent for a new water injection system that could bring exponential improvements in efficiencies and high horsepower gains.

Truthfully, water injection isn’t a new technology, World War II fighter planes used vaporized water to improve low-speed thrust during take off, plus, an extra spurt of speed during dogfights. Post-war, both Saab and Oldsmobile offered vehicles with factory installed water injection systems before the technology enjoyed a renaissance in high-performance Group B rally cars during the 1980s.

Traditionally, water injection has been used as a shortcut to high performance, where a 50/50 water-alcohol mix is injected into the intake manifold where it’s used to lower combustion temperatures and cool the pistons and cylinder walls. This, in turn, reduces the likelihood of detonation and allows for higher compression ratios, which can manifest as either higher performance metrics or a more efficient engine.

But where Ford’s design differs is its focus on injecting water directly into the combustion chamber instead of its traditional upstream location in the intake tract. (Read More…)

2018 Honda Accord Sport - Image: HondaLaunched in mid-June 2017, the 2017 Honda Civic Type R is the first Honda-brand Type R product ever sold in the United States. And after generations of Honda enthusiasts tolerated relatively unimpressive horsepower totals from high-revving four-cylinder engines, Honda didn’t mess around with the latest, turbocharged Civic Type R.

306 horsepower at 6,500 rpm.  295 lb-ft of torque at 2,500 rpm.

Yet before the Civic Type R was even on sale in the United States, we learned that the 10th-generation 2018 Honda Accord would kill the V6 and replace it with, you guessed it, the Civic Type R’s 2.0-liter turbocharged four-cylinder. Incidentally, only a few days after that, we learned that the optional V6 in the Accord’s long-time rival, the new-for-2018 Toyota Camry, would generate 301 horsepower.

Win for Honda? Not so much, as Honda last week revealed a 2018 Accord 2.0T with 252 horsepower and 273 lb-ft of torque.

Huh? What? Why? (Read More…)

2018 Buick Regal Sportback - Image: BuickTwo things leak more than the bathroom faucet at your Great Aunt Martha’s cottage in Saugatuck.

The White House.

And Buick.

It seemed fairly clear three months ago that something was afoot when GM Canada’s Buick.ca website momentarily revealed the 2018 Buick Regal GS’s powertrain: a 3.6-liter V6 and all-wheel drive. But Buick declined to comment, removing from the Canadian website the section that mentioned a V6 offering.

Once again, however, Buick appears to have let the horses out of the barn. Buick’s in-house magazine, B, revealed details ahead of schedule, GM Authority has learned. Rather than the 259-horsepower 2.0-liter turbocharged four-cylinder of current GSs that too often feels underwhelmed, B magazine says the 2018 Regal GS, “employs a high-feature V6 engine that furnishes an estimated 310 horsepower.”

The V6 liveth. (Read More…)

mercedes-gas-i6

While we knew Mercedes-Benz’s AMG sub-brand had plans to dabble in electrification for upcoming performance models, details of what that could mean for the sub-brand’s products remained pretty thin on the ground.

Daimler R&D head Ola Källenius explained back in January that future AMG-badged vehicles will gradually become “more and more electric.” Never mind the limited-production Project One hypercar that’s in the works — that model is just a plaything for the Dubai set. Well, now we know exactly what AMG has planned for the new rung in its model range, and it indeed makes use of charged particles to lend some extra grunt to the overall package.

It also brings a very sweet inline-six to the table. Baby steps, people. (Read More…)

2017 Jaguar XF, Image: Jaguar Land Rover

The engineers at Jaguar have crafted a new engine for the automaker, essentially filling in the last power gap in the brand’s lineup. Carrying the Ingenium name and a 30t badge, the automaker’s latest in-house mill is a turbocharged 2.0-liter four-cylinder designed to fill the space between the automaker’s 2.0-liter turbodiesel and 3.0-liter supercharged V6.

What kind of power, speed and fuel economy will this bring to the 2018 XE, XF and F-Pace, you asl? Jaguar has provided us with the answers. (Read More…)

2017 Audi Q7 blue front

Audi’s European introduction of the beastly SQ7 SUV caused no shortage of speculation last year. Even as Volkswagen Group’s emissions scandal raged, many hoped the raw power of the SQ7’s cutting-edge diesel engine would be enough to compel Audi to bring the model stateside.

Waiting followed. Then, even more waiting. Audi told excited journos it hadn’t greenlit the model for a U.S. launch, despite its very marketable 435 horsepower and 664 lb-ft of torque — power made possible by 4.0 liters of displacement, two turbochargers and a lightning-quick electric supercharger.

Late last year, Volkswagen CEO Herbert Diess put the chill on expectations, telling everyone it wasn’t likely they’d ever see a new diesel Volkswagen product in the United States. This, despite current advancements in diesel technology. It now seems any hesitation the automaker might have felt about that proclamation has evaporated.

Diesels? Dream on. (Read More…)

Ford Motor Company has announced a series of engine and transmission upgrades for the facelifted 2018 F-150 and redesigned 2018 Expedition, all designed to provide a boost in both power and fuel economy. For the Expedition, the upgrades also include an off-road package available as soon as 2018 models begin rolling off assembly lines this fall.

Starting with America’s perpetual best-seller, the F-150, Ford’s powertrain improvements include the addition of dual injection to several engines, expanded implementation of the 10-speed automatic, and a new motor for base trim trucks. While Ford hasn’t released fuel economy estimates, it promises there will be improvements across the range. It was, however, willing to divulge enhanced horsepower and torque specs for all light truck engines, minus the Raptor’s. (Read More…)
