Tetsuya Tada, chief engineer for the Toyota 86 and upcoming Supra, has finally stamped out the possibility of a from-the-factory turbocharged version of the Toyobaru coupe. That’s right, enthusiasts, the Toyota 86 and Subaru BRZ are incapable of being turbocharged.

According to Tada, installing a turbo on the model’s 2.0-liter Boxer engines would require an entirely new platform. That’s odd, considering every reputable aftermarket company offers a turbo kit for it. Equally strange is the automaker’s total unwillingness to seriously entertain the idea of a turbocharged Toyobaru, even though it knew the public was clamoring for one.

“When we launched 86, I got literally millions of questions from around the world of ‘when would you be launching the turbo version?'” Tada said. “I believe that often times I answered that there won’t be a turbo version, and there were some articles in the media that Mr. Tada doesn’t like a turbo.”

While the United States’ obsession with massive V8 engines was picking up steam, Britain was falling in love with the inline six. In the years following World War II, Aston Martin was acquired by David Brown for a pittance and entered into the era that would define it forever. This era included the engine stylings of Tadek Marek — a man with a serious penchant for the straight six. Eventually both Aston and Marek would move on to motors with more cylinders, but the company would still hold onto the inline six until the new millennium as an entry-level option. It’s last application was on the base-model DB7.

Unless you count the DB4’s continuation, we’ve not seen any Aston Martin hosting a straight-six configuration since then. However, the company recently let slip that it’s talking about borrowing one from Daimler. Specifically, the turbocharged 3.0-liter from Mercedes-AMG.

One’s an ancient model that continues to sell in significant numbers; the other’s a fairly radically styled new model in the same compact crossover segment. Together, the Outlander Sport (RVR in Canada) and Eclipse Cross make up two-thirds of Mitsubishi’s utility vehicle lineup.

It seems these two rivalrous siblings — separated by $2,900 and a host of powertrain differences — will share the same segment for some time to come, as there currently isn’t a next-generation Outlander Sport in the pipe. We might wait nearly three years before one appears. In the meantime, anyone willing to shell out less dough for a two-row Outlander Sport can expect to save cash on gasoline, as well.

It may have the smaller engine of the two, the Eclipse Cross has the greatest thirst.

If you’re prone to daydreaming about slinky roadsters and curvaceous coupes powered by a high-revving rotary engine, this news might disappoint.

Mazda, one of a dwindling handful of automakers not in possession of an electric (or even hybrid) vehicle, plans to change that status next year with the introduction of a small battery-powered car. Coming along for the ride — at least in one variant — is a rotary gas engine designed to go unnoticed by the driver.

It always felt little odd whenever a diesel-powered Cayenne sidled up to you next to a stoplight. A Porsche that builds SUVs, we used to mull, and diesels, no less!

The public’s discomfort with a German sports car maker entering the utility vehicle field is long gone, and we can now say the same for Porsche’s short-lived dalliance with diesels. The automaker has stated it’s pulling its last remaining oil-burning models off the market.

A new Porsche is born, cleaner, but perhaps no purer.

One of the red-circled events on my calendar every year is the Detroit Autorama, arguably the world’s best custom car and hot rod show. As is fitting for an event in the Motor City, the vehicles competing for the Autorama’s top prize, the Ridler Award, must actually function, they have to be driven onto the show floor under their own power, and the hoods are up during judging so the judges can evaluate the engine compartment.

While that makes for fair competition, it also makes for less-than-ideal photography of the cars’ styling. No kid sitting in seventh-grade study hall ever drew a hot car with the hood up.

It might surprise you, then, that I was excited to find out about the Engines Exposed exhibit running until the end of February at the Henry Ford Museum’s Driving America display.

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?

We explored the Fiat brand’s troubles earlier this week, then put you in the driver’s seat and asked what you’d like to see done about it. Well, there’s no red telephone linking our comments section with Fiat Chrysler Automobiles HQ, so suffice it to say many of your suggestions probably fell on deaf ears up in Auburn Hills.

However, Fiat does have a plan to stimulate some renewed interest in its flagging 500 city car, but it’s not through a shocking redesign or by positioning the tiny vehicle as a trail-conquering off-roader. Up until now, non-Abarth 500s have, to put it mildly, underwhelmed from a performance standpoint. Double-digit torque figures are a rarity these days, but they’ve just become rarer.

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.

(In the interest of providing readers with all the news they can use, we sometimes tap sister publications when an article attracts our interest. In this piece by Matthew Guy, published by Off-Road.com, our in-house truck lover tries to find out when Nissan’s promised six-cylinder Titan will finally make its appearance.

Nissan has been doing a good job getting back into the full-sized truck game, rolling out various cab and bed configurations for the Titan along with an array of trim levels. There’s still one thing missing, though – a V6 engine.

Right now, truck customers walking into a Nissan showroom are limited to a single engine in the half-ton Titan. The 5.6-liter Endurance V8 is a great motor, cranking out nearly 400 horsepower and an equal amount of torque and allowing drivers to tow nearly 10,000 lbs, but not everyone needs that hauling capability.

In an era where just about every automaker is talking about electrification of its powertrains to some extent or another, Mazda is taking a different tack — remaining heavily focused on the good ol’ internal combustion engine.

This doesn’t mean electrification isn’t part of the company’s future powertrain strategy – it is – but in the nearer term, the company is working on ways to increase power while boosting fuel economy in its small gas-powered engines.

(Before we get to that, yes, the company’s long-promised diesel is still coming to America, though there’s still no official date.)

In order to show off its new tech, Mazda invited journalists to its research and development HQ in Irvine, California to drive prototypes outfitted with the Skyactiv-X engine.

We told you recently of the tsunami of complaints from Ford Focus RS owners swamping the National Highway Traffic Safety Administration — and other agencies — with minor gripes like, say, their brand new car burning engine coolant. Well, there’s a fix afoot.

In a recently released service bulletin, Ford describes the issue plaguing its hottest hatch and vows to replace every cylinder head installed in a Focus RS built between August 3, 2015 to July 6, 2017. That is to say all of them.

This is the sixth model year for the third-generation Mazda 6 which, despite its age, remains arguably the best-looking midsize sedan on the market. Mazda belatedly answered long-standing cries for more power by offering a turbocharged 2.5-liter inline-four for 2018, giving the model the grunt it needs to back up its sporting pretentions.

We now know what drivers can expect at the pumps from this engine, borrowed from the CX-9 parts bin. However, can the emergence of a true Mazda 6 sports sedan rekindle waning interest in the model?

While Ford hasn’t announced the pricing of the new Bullitt Mustang, the first example just sold for three-hundred grand at auction. We’re presuming future production models will be considerably more affordable because, damn, that’s a lot to spend on an appearance package and a few extra horses — even if the end result is undeniably cool.

Fortunately, all the proceeds went to supporting the Boys Republic — a charity near and dear to Steve McQueen. In addition to being remanded to the school after his own mother signed a court order that he was “incorrigible,” a matured McQueen often visited its children during the holidays and frequently donated large sums of money to the organization.

General Motors has a new in-house 3.0-liter inline-six turbodiesel planned for its next-generation full-size pickups, and, while it won’t be available from launch, now we know where it’s being built.

GM’s vice president of global propulsion systems, Dan Nicholson, says the engine — which came as a surprise announcement during the 2019 Chevrolet Silverado’s weekend debut — will hail from Flint, Michigan.
