One thing is clear — with variable compression comes a newfound lack of thirst.

Infiniti’s previous midsize QX50 crossover didn’t astound in its thrift, garnering 20 miles per gallon on the EPA combined cycle. The move to a new, front-drive platform and addition of a years-in-the-making gasoline engine for 2019 has done wonders for the model’s drinking habit, however, and Infiniti engineers pegged the MPG figures right on the nose.

With the 2019 QX50‘s fuel economy now confirmed by the EPA, it begs the question: just how much of the model’s thriftiness can the variable compression engine take credit for? Read More >

The relationship between humans and cars is poised to become quite different in the years to come, or so the automakers warn promise us. Autonomous vehicles will whisk us to whatever destination we desire, simply by inputting our desired address into a navigation system or, perhaps, just by speaking it aloud. Already, the level of communication between humans and the modern car astounds.

We’ve come a long way from Chrysler’s Electronic Voice Alert, that nagging companion of the 1980s.

Now, Ford Motor Company looks ready to take our current relationship to the next level, while putting the human in charge. A U.S. patent published today describes a car that opens its doors only when it hears its master’s voice. And by “open,” we mean wide open, not just unlocked. Read More >

Automotive soothsayers have foreseen the coming Armageddon, where private car ownership vanishes and we’re all ferried around in robotic taxis or rental vehicles, and manufacturers have taken their divinations to heart. Either that, or the opportunity to diversity already successful companies is too tempting a prospect to pass up. As such, we’ve seen “mobility” become the new industry buzzword — used as a fill-in for electric vehicles, autonomous development, and ride-sharing/hailing programs.

Hoping to expand its own mobility services, Daimler has announced an openness to seek broader alliances just days after BMW Group bought out its rental car partner, Sixt, from their joint car-sharing program DriveNow. That sets the stage for a peculiar partnership, as the two German automakers have a long, competitive history with each other — one which sometimes results in passive-aggressive behavior.

Here at TTAC, we sometimes offer up a story published by a sister publication after deciding it’s something worthy of your time. This piece, published by GMInsideNews, fits that bill. While the soulless autonomous future scares many of us, General Motors is working on a way to stop those driverless cars from plowing over each and every one of us. Read on.

General Motors continues to pour money and time into perfecting vehicle autonomy.

One of the integral themes of an autonomous driving future is communication. Vehicles will be required to rapidly and constantly talk to one another, relaying position, speed, and intent, with the same demands applying to our roadways and intersections — which will be expected to relay weather, traffic, and safety information in real time as vehicles approach.

Pedestrians, however, pose a unique problem. In busy cities, pedestrians and drivers routinely communicate nonverbally by making eye contact or gesticulating, but an autonomous vehicle doesn’t have that privilege. Its machine code is dependant on a series of binary questions it must ask itself in order to determine if the person is a threat, which — if affirmative — currently results in the car coming to a halt, which on occasion has caused a rear-end collision, or two.

Well, GM is working on a system in which autonomous vehicles will be capable of better understanding the motions of pedestrians by communicating with their Internet-connected devices, be it smart-phones, wearables, or perhaps even future advancements made towards transhumanism. Read More >

Iron or aluminum? For cylinder head construction, that’s the basic menu we’ve long grown used to. There’s advantages and drawbacks to both. Aluminum is lighter, but more prone to warping. Iron is stronger but heavier, with low thermal conductivity. Both materials are prone to the ups and downs of the commodities market, frustrating beancounters working at automakers everywhere.

In a U.S. patent application filed in October and published today, Ford Motor Company’s global tech division proposes something new: a cylinder head containing a barest minimum of metal. Called the Hybrid Composite Cylinder Head, most of the component’s bulk is made up of polymer composite, not aluminum or iron. Read More >

True story: when my pal “Creighton” decided to start using his Charger Hellcat for Uber, he called his insurance company and had them upgrade his policy to commercial status. Doing so pretty much wiped out any profit that he was going to make as an Uber driver, but he still made the call because he’s the kind of person who doesn’t like to take unnecessary risks.

Getting rideshare-specific insurance isn’t always prohibitive, but during my conversations with various Uber and Lyft drivers I’ve yet to hear of anybody besides Creighton actually ponying-up for real additional coverage. Most of these people are living pretty close to the bone and they don’t really think they have that much to lose in the first place. Plus, there’s the fact that both Uber and Lyft offer some additional coverage as part of their driver agreement.

That’s the theory of it, anyway. What happens when two Lyft drivers collide? Yesterday, someone found out.

Waymo, the self-driving division of Google’s parent company Alphabet, just announced it has reached a deal to purchase a buttload of Pacifica minivans from Fiat Chrysler Automobiles. Alright, to be fair, it didn’t actually use the term “buttload.” It said Chrysler would provide “thousands” of units, which will ultimately be outfitted for autonomous driving.

Unfortunately, neither company seems willing to disclose an official count. Waymo currently has around 600 self-driving Pacificas in its fleet, so even an extra thousand vehicles would equate to a multi-million dollar deal and the exponential growth of its autonomous development program.

“With the world’s first fleet of fully self-driving vehicles on the road, we’ve moved from research and development to operations and deployment,” Waymo CEO John Krafcik said in an official statement. “These additional vehicles will help us scale.” Read More >

New York City and San Francisco, besides having the most tailored beards and bike activists on both coasts (Note: Portland might have something to say about this) might not like some of the data emerging from the University of Michigan.

While some Millennials, especially ones working at startups and paying the equivalent of a Cadillac for a shoebox apartment in a trendy, upcoming part of their building, might think personal car ownership is as dated a concept as VCR tapes and telephone banking, there’s a vast gulf between that lifestyle and that of the average American. It’s clear to see in the U-M Transportation Research Institute’s latest findings.

The data also pours a cold glass of asparagus water over an earlier poll that suggests we’re poised to kick car ownership to the curb. Read More >

With automakers, the Department of Transportation, NHTSA, and Congress all attempting to get self-driving vehicles onto the road as quickly as possible, the autonomous revolution finds itself in a sticky situation. Some motorists are confusing their semi-autonomous technology with an impenetrable safety net. This has resulted in avoidable accidents as drivers assume their high-tech cars can cope with whatever’s thrown at them, and it’s probably going to get worse as more idiots buy them.

We’ve already covered how semi-autonomous features make everyone less-effective behind the wheel and the fatal Tesla Autopilot crash was a story we kept up with for over a year. Investigators ruled that accident was the perfect storm of mishaps, however, there remains a common thread between the two pieces. The driver may have been spared were he not so eager to put his faith into the vehicle’s semi-autonomous system.

On Monday, a Tesla Model S collided with stopped firetruck that was responding to an accident on a freeway in Culver City, California. As you already guessed, the driver told the firefighters that the vehicle was operating in Autopilot mode. While nobody was injured in the crash, it’s another stroke in the ugly portrait of people placing blind trust in a technology they don’t understand. And, boy oh boy, are we just getting started on illustrating this problem.  Read More >

Bipartisan legislation to “promote the safe development of autonomous vehicles” is currently being held up by a trio of Democrats, according to U.S. Senate Commerce Committee Chairman John Thune. While much of Congress is hoping to push the AV START Act through, Sen. Dianne Feinstein and two colleagues have blocked unanimous consent — stalling the bill’s swift progress by forcing a floor vote.

Thune, who sponsors Senate Bill 1,885, told reporters he hoped Feinstein and the other Democrats would see the light. “We could save a lot of lives,” Thune said, adding that 94 percent of car crashes are caused by human error. “It is cutting-edge technology, transformational in terms of the economy.”

However, the opposition isn’t convinced autonomous vehicles are at a point where it’s safe to roll them out en masse on public roads. Read More >

The car industry was one of the first to employ widespread automation as a way to streamline manufacturing. However, plenty of jobs have been handed over to robots since the 1980s. Cashiers, tollbooth operators, librarians, and practically everyone who has worked in shipping has seen some aspect of their job replaced with automation. But automakers now claim the usefulness of robots has reached its peak — at last for the time being.

In the midst of an autonomous revolution where drivers will be eventually be replaced by computer-controlled vehicles, numerous carmakers suggest robots still can’t substitute humans on the assembly line.  Read More >

Waymo, the self-driving unit of Google parent Alphabet, is testing the crap out of its ever-growing fleet of autonomous Chrysler Pacificas. While we know the company has already mapped dozens of North American towns, the majority of its testing takes place around Austin, Detroit, Palo Alto, San Francisco, Seattle, and especially Phoenix.

However, today the company tweeted out that it will add Atlanta, Georgia, to that list. Presently, Arizona is the only region where Waymo routinely operates vehicles without a human behind the wheel. But that’s liable to change as the firm gets more testing under its belt. Atlantans may be leaning out of car windows to snap photos of driverless vans soon enough.  Read More >

General Motors launched its Maven rideshare service in 2016 with the goal of providing renters with a taste of its vehicles, while also bringing in a little extra revenue. The service offers a wide array of vehicles ranging from small hatchbacks like the Chevrolet Spark to large SUVs like the Tahoe.

The service is available in many larger cities across the country and, since I was visiting Detroit for the auto show, I decided to give it a try to see what a potential renter might encounter. I signed up for the app and rented a couple of vehicles without notifying GM in order to experience the vehicles just as the general public would.

The vehicles were far worse than I expected.

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.

In the first half of last year, the number of new vehicles sold in Europe with a diesel engine under the hood (or bonnet, depending on your port of call) fell below that of gasoline-powered vehicles.

Spurred on by various tax incentives aimed at boosting national fuel economy, diesel’s popularity hit a high water mark in 2011, with 55.7 percent of all passenger cars sold in Western Europe that year leaving the lot with a compression ignition powerplant. However, since Volkswagen’s debacle, automakers, governments, and consumers are having second thoughts about the fuel.

After seeing the diesel take rate fall 17 percent in 2017, Britain anticipates the overall market share for oil burners could hit 15 percent in 2025. Germany, birthplace of diesel fandom, saw sales sink 7 percent last year, now standing at 38.8 percent of new vehicles. The French take rate is now below 50 percent, as well.

Replacing the incentivized high-torque engines isn’t a job that can be handled by gasoline alone, not in that market, anyway, which is where hybrid vehicles come in. For Toyota, this as much a problem as an opportunity — one that could have an impact on North America. Read More >
