The 2018 Subaru Outback 3.6R packs a 6-cylinder boxer engine, but you may not be able to get it for much longer. One look at the all-new 2019 Subaru Ascent tells us the 3.6R in the Outback and Legacy could be like the NFL, (Not For Long).

Subaru developed the new 2.4-liter twin-scroll turbocharged four-cylinder boxer engine for the new Ascent family hauler producing 260hp and 277 lb. ft of torque. The Ascent 2.4-liter twin turbo four cylinder is their new-generation boxer engine developed specifically for this vehicle that’s built at Subaru’s U.S. factory in Lafayette, Indiana.

Why is the 3.6-liter engine in Outback and Legacy going away? It’s because of the tighter fuel-mileage and emissions regulations around the globe. Automakers need to downsize engines and make them cleaner burning for the new California and European regs. But it’s not such a bad things for consumers.

Subaru says, despite the Ascent 2.4-liter’s smaller displacement, the newly developed four-cylinder turbocharged direct-injection boxer engine will achieve smooth acceleration equal to or better than that of competing vehicles with 3.5-liter 6-cylinder engines. That is accomplished by adding torque over horsepower, because torque is what gets a vehicle moving from a stop and helps in pulling the vehicle up a hill, or when towing.

Take a look at a few examples in the story below and you’ll see why its a good thing for new-generation Outback and Legacy buyers when they arrive with a new turbo four cylinder engine.

Subaru is correct when they say the all-new Ascent 3-Row will achieve smooth acceleration because of torque, equal to or better than that of competing vehicles with 3.5-liter V6 engines. The new 2.4-liter twin-scroll turbocharged four-cylinder boxer engine has more torque than any of the competition’s larger 3.5-liter or 3.6-liter V6 engines, and it should get improved fuel-economy over the competitor’s V6 powerplants.

The all-new Ascent 3-Row, is powered by the brand’s all-new direct-injected turbocharged 2.4-liter Boxer 4-cylinder that beats the current Outback 3.6R engine. The 3.6R develops 256 horsepower and 247 lb. ft of torque. Both short of Ascent’s 260hp and 277 lb. ft of torque.

The 3.6R’s demise is no surprise, because Subaru Corporation spelled it out in their “Prominence 2020" plan. The plan outlines every Subaru boxer engine will come with the latest Direct Injection technology. You’ll see smaller turbo engines developing more power and with greater fuel efficiency in the new-generation Subaru vehicles.

The 3.6 Liter 6-cylinder Boxer engine in the Outback and Legacy is going away soon. The new-generation models, when they arrive sometime in 2019, will likely be powered by new twin-scroll turbocharged four-cylinder boxer engines like the new 2019 Ascent. So if you still want the larger displacement 3.6R 2018 Outback and Legacy model, you better get one soon, before they are a thing of the past.

The 3.6 engine is exceedingly smooth with ample power for merging and passing on the highway. Subaru will lose me as a customer when they drop the 3.6.
Yep second that
How can you be so narrow mind when you have n't even tried it. it is stupid to say that you won't buy a vehicle because of dropping engine for a better engine. stupid
The quality of an engine and its drivability is not just measured by horsepower and torque numbers. DI and blown engines are more complex and costly to maintain and repair. If you dip into the throttle too much, fuel economy is no better than a larger engine. I have driven the BMW turbo 4. Garden tractor idle quality, poor quality start/stop and uneven power delivery at low speeds. Do your homework before you post a comment.
Well, I can certainly tell very easily that you are COMPLETELY UNFAMILIAR with the absolutely fantastic 3.6 engine.. It is one that will last virtually forever if properly maintained. By the way, those turbos REQUIRE HIGHER OCTANE FUEL!... NO THANKS
I can't wait for all the people that drop Subaru because the limited little engine will be working so hard on the upgrade hills, when pulling the 5000lbs behind it, plus the Ascent it's self weighing close to 5000lbs. And will it even be safe enough to handle the weight. I will not be buying anymore from Subaru.
Anybody who eliminates a car without even trying it should not be taken seriously.
We have just purchased our first Subaru 3.6r Outback. It is a great motor wish they came with a standard turbo. Would think hard about replacing it with a 4 cylinder engine. Maybe I am old school but love the 6s and 8s. Will sneeek a peek at the new engine hope subaru do a good job and it is as reliable as their current engines.
We are on our third 3.6R Outback and we love it. It may not have the "twin turbo" of the new 2.4L, but WHY should I get a TURBO when they all require Premium Gas..at almost $.50 more per gallon??? Now, with gas on a horrendous rise, it is going to really BOOST our gas expenditures, and I am on a fixed-income VA Disability.
I have had experience with several four-bangers and all of them were rough. Also, like most Americans (I hear), I am allergic to paying for premium gas. I have a 2015 3.6R Outback and am looking to purchase a 2020 Outback with the new architecture and better tech. I am waiting because there is no point in buying the same car I already have. However, If all Subaru has to offer for 2020 is small turbos that require premium gas, I will probably go someplace else, or keep my 2015.
My 2016 WRX ran perfectly on 87 octane. My 2017 3.6R also runs on 87..... Not sure why you think it will require premium fuel. It’s not an STI.
No thanks to Premium gas. If I won Lotto, I wouldn't buy a car that took Premium, The CX9 has an option to get more HP if you use premium but I'd like to see long term results before I use regular gas in a turbo. My 2011 Outback isn't the fastest car in the world but the gas mileage is amazing. Just wish it had a bigger gas tank, I'd be annoyed at the occasional need for passing someone with a 3.6R vs. having to get gas every 320 or so miles. Bigger gas tank would be nice. BTW, how hard is it to put lumbar support for the passenger seat? I've had moonroofs for over 30 years and have used them less than 10 times. Biggest waste of money. The passenger lumbar would be used 100X more. You fixed the self changing oil, the horrific headlights, now give the wives with bad backs a break. I've seen this complaint many times over.
If you are referring to the 3.6 litre needing fuel every 320 miles or so, you must be quoting the city only mileage...on the highway mine would get down as low as 27 mpg going a steady 75 mph fully loaded, otherwise at 60 mph with only me in the car I would ALWAYS see 30+ mpg!
We are looking at replacing our T. Sienna that has the 3.5L V6 with a new Subaru Outback. Please share any info you have on the redesign (model update) on the Outback. Can wait for the 2020 model at the latest (would like to get a 2019 as soon as available); but, not if there is a complete update in the works for 2020. Regarding the 3.6L being replaced by a Turbo 4, surely they will stay with the boxer design which should be a smooth running engine despite the turbine boost?? Please post any info on the update as soon as available. Thanks.
Unless there is clear acknowledgment and a plan of action for dealing with deposits on the backs of intake valves in DI engines where they typically don't get cleaned with fresh gasoline spray but do get recirculated exhaust gas and PCV oils deposited on them, I'm not even considering buying another one. Been dealing with this on our VW 2.0TSI every 35k miles. Needs the intake manifold removed and each valve hand cleaned or you get poor performance and eventually misfires. BMW owners have been having fun blasting walnut shells at their engines to clean this crap off. Whatever gains in performance there are when new/clean are gradually lost over 30-50k miles. And then you take apart and clean again. Toyota is now using an extra spray fuel port to periodically hose off the valves and Mazda Skyactive engines keep the area less cooled to alleviate the buildup. Again without a clear description of what Subaru plans to do to address this, Not interested in Direct Injection engines.
No need to discontinue the Outback because it created all the crossover from all car different models
I will not have a vehicle that can't preform in the manner that is advertised. Last year Subaru advertised that the Ascent was coming out with the 3.6 H6. Now they lie about it and say that the new engine is better. I have a 2008 Tribeca and it is as strong as it was when new.and I don't need premium gasoline in it.
I would suggest driving the new Ascent before you write it off. I did so right after I drove the Outback 3.6 H6 for comparison. The Ascent easily competes with the 3.6 in power and torque and I was surprised at how wide the torque band is. I detected no turbo lag. And the Ascent riding on the new Global Platform I thought gave improved ride and handling over the Outback. I ordered one and am awaiting delivery.
