Volvo's engine lineup once offered too many options, keeping the costs of the individual engines high. The many variants have been simplified down to a single engine architecture, which now has both gasoline and diesel inline four-cylinder variants. The gasoline four cylinder features a turbocharger as well as a supercharger, allowing for good fuel efficiency, great response, high horsepower, and a wide torque curve.
As a result, this T6 engine architecture has won numerous Ward's Auto 10 Best Engine awards. In this video we'll be looking at the 2018 Volvo S90 T6 Inscription AWD, with it's 316 horsepower and 295 lb-ft of torque twincharged engine. But it doesn't end there. For the T8 engine Volvo adds a crank-integrated starter generator (C-ISG), as well as a rear-axle electric motor for AWD. The result is a plug-in hybrid with instant torque, good fuel efficiency, and loads of power.

The audio sucks, I know! I’m very sorry about this. As a one man show I always do my best to check focus, lighting, white balance, audio, etc, but sometimes things slip through. In this case my lapel microphone failed to record audio, and I did not find out until editing the footage weeks later. From a time perspective, reshooting really wasn’t an option to maintain my schedule. It’s quite reasonable for audiences to expect a certain level of quality from established channels, and for that I do apologize as this was never my intention. I will do my best to ensure this doesn’t happen again in the future, but I’m sure I’m far from being done with making mistakes. I hope you all can enjoy the cool technology that Volvo packs into this engine, and thank you all so much for your continual support of this channel! I hope you’re having a wonderful day!

Alternative headline: “New Volvo engine has highest cost of lifetime maintenance ever produced.”

[@looncraz]

You would think so, but not really. The only thing in the system that would fail within the 200,000mile range would be the bypass valve - the symptom being a loss of power either down low or up high... or possibly dual torque peaks because it's partially stuck open. The supercharger clutch could prove an issue as well, but it may very not. So long as oil changes are kept up, I see no problems with these new Volvo engines lasting as well as the ones they replaced... but costing less to own. Spark plugs will probably need a faster replacement, but that's about it. Eaton oiled superchargers are very reliable - and this one only operates under acceleration from about 1800RPM to 3500RPM, sitting idle the rest of the time. The turbo is designed to only spool up high, so the wastegate is decently far open, so it isn't seeing much of any action, either. This is how the fuel economy on these things is so good - it's just a simple, high quality, 2.0L naturally aspirated four banger until you hit the gas. The T8 model, with all of its electrics, doesn't add anything complex - every part in that system should last 500,000 miles easily (battery notwithstanding).

[@peglor]

We'll have to see how they're looking in 3-5 years before we can decide whether this is a genuinely good engine or not (Good engines don't cost a fortune to keep outside their warranty). The supercharger clutch would be the part I'd worry about - if it's going from stopped to 20,000+ rpm in 0.8 seconds as implied by the video, I can see this part shitting it's guts right out in no time. I have heard that Volvo are doing very well on consumer reliability surveys though, but the D2 and D3 engines are almost all people buy here, and I suspect in a lot of Europe, so the good reliability reports are probably not based on the T6 and T8 level engines.

[@looncraz]

I agree that we really need a few more years to know how the reliability will truly be for the T6 drive-e engines. So far, they are looking to be as reliable as the engines they have replaced (I6 twin-turbo engines). These engines have been around for a little more than four years, though, so we are not without data. The T6 engines had some initial issues with detonation due to oil getting by the low friction piston rings or some such, but that was quickly resolved. As with any boosted engine - anything that causes detonation or uncontrolled knock can potentially destroy it beyond the point of repair. The clutch itself is going from idle to crank speed from as low as zero to 1,500 RPM~3,500 RPM, the supercharger is geared and will spin from either zero or some idle speed to 20,000 RPM - just like any turbo, but with a bit more force. I suspect the clutch mechanism is basically a torque converter with a lock-up and bypass for higher engine RPMs - very similar to how Volvo does their VVT. That would allow the supercharger to be brought up to speed more gently and would be very reliable, requiring only one solenoid, oil pressure, and a belt drive... but would also mean the supercharger input shaft is likely always moving when the engine is running.

[@woooweee]

More than a valve, the problem of heat is baked into this kind of solution when you try to do more with less. I just don't see how it could wear less severely than a more standard solution.

[@looncraz]

The wear is reduced by careful design. Floating bearings for the camshafts, direct injection, wideband sensors, inter-cooler, careful packaging, cold spark plugs, dynamic VVT tuning, tuned exhaust flow, layers of heat shields, aggressive fan response with PWM control... all stuff Volvo, Mercedes, and a few others have been doing for over a decade to great effect. An engine that can handle putting out 450HP+ with just a tune but is only putting out 316HP from the factory is an engine with healthy safety margins.

[@Drifty325i]

People are saying that this engines to complicated, to much to go wrong, service costs etc, tell me what in that engine is so complicated and high service costs? There’s allot of tech in there but it’s all actually pretty simple. There’s virtually no service for the SC and turbo side. The engines not running high boost as the CR ratio is fairly high so the engine should be solid . The amount of sensors etc are almost identical to most conventional turbo cars. The only thing would be the integration of the electric power, however this tech has been out for a decade now and it’s super reliable. I don’t get the issue? have they proven to be unreliable since they launched that engine?

[@EngineeringExplained]

Agreed. Yeah, I’m not here to say it’s reliable or not, I don’t have the data, but so many folks making a conclusion after 5 minutes about an engine that a team of engineers developed for years. If you don’t have data to the contrary, no point in making wild claims about it.

[@moviejose3249]

The Chinese bought a lot of tech for a very cheap price when they picked up Volvo from Ford. Probably one of the best bargains ever.

[@Drifty325i]

Engineering Explained totally agree mate

[@marek196c]

the point is, not engine itself, as the engine can be bulletproof, but in the case it is engineered tolerance of 0.5 on calculations and 1 of things fail can be catastrophic for the engine (obviously they won't explode as in Hollywood films), or if in future will be mounted in mote family or sporty cars (like let say s40 or c30) and you will be like, I want 100hp more so I will slam bigger turbo, and the engine will be like: STOP, or I will fly like a rainbow so high. Sadly they don't over-engineering them anymore.

[@JP-zp5ic]

The issue as I see it is the sheer number of interdependent systems working together. The more systems you have, the greater the chance that one of them will fail within a given period of operation. While the odds of having a large repair bill earlier on in the use of this vehicle are probably not very much higher than for a less complicated model, the difference is likely still significant. The other side of the coin is that this entire design focuses strongly on overcoming turbo-lag while maintaining very high fuel efficiency. It's elegant, but in the end I have to question how much of an advantage that's going to be. Would it perhaps be more worthwhile to drop the supercharger, fit the vehicle with an ultracapacitor, and beef-up the capability of the electric power components? Electric engines give much better torque at low rpm to begin with, and enhancing the hybrid character of this model could well provide equal performance gains.

[@mertz313]

I've always found this setup interesting, but I've always wanted to hear a mechanics perspective on it since they'll be the ones that fix it when it goes wrong and costing me money.

[@combustinghandshakes8617]

[@veryfunclub]

Emissions stuff will be an issue, but the turbo and supercharger are both in fairly easy to replace areas. Some of the T5’s before 2019 consumed oil, but all the T6’s and new T5’s have no known issues

I am going to disagree here, by adding more breaking points ie clutches, belts etc, reliability should comes to play with time. Also while turbofan engines are complex at the root of it they couldn't be more simpler a single shaft with compressors and a fan attached to the front. I really don't see this engines outlasting one of the 2.x accord engine or a corolla for example and that's not factoring the probably insane amount of maintenance money.

This is a new engine, anything new that hasn't been tested in the field by thousands of people will show its true colors when it is. Neat idea, but I doubt this is an engine that'll last you 300,000 kilometers without any big issues. But hey if it does, wow great engineering! I'll just stick to the tried and true engines that have been used by thousands of people and shown to be reliable and great.

[@commanderoof4578]

If an engine has no supper-charger and not turbocharger the engine will last longer. I have non turbo engines to die at 100k miles about 160k kilometres. But have know engines that have no boost that have lasted 350-400k miles around 1.6x that.

A 7.6L with room to sit in the engine bay and work on it if I chose to. Easily accessible parts for general maintenance. Simplicity and reliability. I’ve had many cars over my life, and engine bays get more crowded, less accessible, and more electronics to go wrong. Current car, I have to pull the front bumper to change low/high beams, blinkers, and fog lights. Remove a tire and wheel well shrouds to change spark plugs, and the coolant reservoir has a special side tube with a float that measures level, that it can get stuck and throw a dash light even when it’s above the full level to name a few complications. It’s just not worth it. It is more than nostalgia, it was just more owner friendly.

Instead of adding all this complexity why not add a variable geometry turbo on a I4? Honda currently makes the K20C1 that produces similar HP and torque figures and it's VERY reliable. It's not even a variable geometry turbo, so that engine has a lot much potential. Furthermore, with the K20C1, it can be tuned to produce numbers that decimate Volvo's twin charged engine. I'm not understanding why add all this complexity that give mediocre metrics (horsepower and torque) when it comes to performance.

A lot of them even without good maintenance! The les reliable engines are the 5 cilinder 185hp diesel (2006-2010) and the latest 2.0 4 cilinder diesel. Changing a Waterpump (Volvo engines) isn't in the maintenance interval up to 300.000km since the Volvo 850 in the early '90! in 20years i maybe replaced 2 of them, spark plugs for the 5 cilinder gasoline every 120.000km. Clutch changing km are for 90% over the 250.000km, and here in Europe we use the clutch every 500m. The last exhaust i replaced was in the early 2000 on a 940 with 300.000plus km, after that only 1 because of an accident. Not 1 turbo on a Volvo engine in 20years.Rust is a word we haven't used since the 850 models. I repeat Volvo engine because they use foreign engine in some models. And of course there are exeptions. That said isn't a Volvo completely bulletproof but price/quality there is no better european car.

[@error079]

What happened to the air tank boost system?

[@lolzordje123]

error079 you mean PowerPulse? Thats only on the diesel versions.

[@claytons2101]

With an partly eletric car, you can eliminate the need for a turbocharer air compressor (that was used to aid the supercharger early on by letting the Turbo swool up early, effectivly using both at the same time). But with a Hybrid car, the throttle respone is instantaeous. This combined with an intant power boost from the supercharger and boom, you've gotten rid of the need for the air compressor. Sure you could keep it in if you wanted, but thats just one more complicated system that will require maintanence down the road.

[@lolzordje123]

Clayton Spencer explain the v60 hybrid? It has double turbos and electric motor

[@alenko4763]

So?? Where does he say that you cant have turbos and electric motors? He said that you don't need an air compressor.. Which the V60 hybrid doesn't have.

[@srpsbb2000]

Well, long term update. I got a 2017 xc90 with this engine, I did get the polestar tune from volvo which added another 25hp? Can't remember. But 87k miles and the supercharger failed, not happy. No lights, warning or errors. Just a dead pedal below 3k rpms. Not acceptable.

[@ryukiddin]

Ty, I was currently looking at v60 t8. All this technology seems amazing and I'm not ready to go full EV yet. But asking for all this power from a 2 l engine most certainly has to come with some downfalls. I don't lease I buy and keep for a long time so I will keep away thank you again

[@srpsbb2000]

@@ryukiddin I also had fuel injector issues, and it killed 2 catalytic converters. No clue why. I run 91 octane and followed all recommended service. The cats were covered under warranty and they cut me a great deal on the labor for the fuel injectors, but these issues are piling up and it makes me nervous since this is my wife's daily driver. I want to dump it, but after just dropping 4k on it, feel I need to keep it at least another year.

[@beng8391]

I would never ever think of Volvo as a luxury brand or as something worth buying. They will always be an old people brand or heavy machinery to me. Plus now they’re owned by China so just like jaguar and Land Rover, their prices and luxury went up but their actual quality and longevity has gone down. You can’t pour gravel into the cylinders and drive with it like that anymore, unlike some historically tough older models. If you want good low end torque, fuel efficiency and reliability, you just need some basic designs. Like small turbos, narrow cylinders and some strong components. You’ll get an engine with plenty of low end torque, a flat power band and if you don’t have a ton of displacement and weight you’ll get good mileage.

[@pkquick2009]

Ben G - You've just described everything a Diesel is . . . and why they're safer in an accident.

[@beng8391]

But you can’t pour gravel into their diesels anymore now can you?

[@beng8391]

And Incase anyone is confused by my comment, Land Rover and Jaguar aren’t owned by China, they’re owned by TATA motors which is Indian. Which isn’t any better

[@wangshuokevin]

You made a lot of claims without any fact to back it up. This new Volvo's quality is much better than those old ones produced by Ford. I just don't get why anyone is so obsessed with reliability, I bought a 2018 XC90 T6 Inscription, fully loaded at 73K MSRP, and bought an extended warranty that covers 8 years/100K for 2700 bucks. So even the car worth 0 at the end of 8 year, I'm out less than 10K a year for this car. There are many people like me so there is a big market for luxury vehicles. Also those reliable old models are just not as safe as new vehicles, I value safety, handling, quality and power over reliability.

[@cicero1178]

Shuo Wang Define quality

[@EduardQualls]

Leased an XC60 T8 in 2017: got the first one delivered in Texas. Only problem so far is that the engine/drive train is so quiet & powerful (400HP; 0-60 in 4.9s) & the ride so smooth, that it's very easy to exceed the speed limit significantly, if you're not paying attention. With work-at-home & everything else within electric range, the car has complained twice that the gas was getting old: 2 fill-ups in c. 11 months. Lease ended September, 2020. Residual owed: c. $32k; Blue-Book value: $45k. Yes, I bought it.

[@yongyongli928]

gonna buy a Xc90 T8. wondering what would happen if gas get old?

[@JamaicanMeCrazy]

Funny thing is it isn't that fuel efficient and not all that powerful either neither is it all that light. Simple is almost always better.

[@mediumunwell]

This is an engine meant for wowing new car buyers. This engine will not last without having copious amounts of money thrown at it, be it from the warranty or from the unlucky SOB that bought it without a warranty.

[@looncraz]

It's a Volvo engine. It will have no difficulty lasting as it's far more overbuilt than you think... you can probably push the engine to >500HP without changing internals or even reducing service life. It will need quality oil and more frequent spark plug changes, but that's it. Direct injection eliminates most risk of predetonation and knock killing the engine (as you don't have an air-fuel charge, only air, then the fuel injects when it's time to ignite). The supercharger is oiled by the engine (most likely - I haven't checked - but Volvo is pretty aggressive with their lubrication) and will usually be clutched to the off state - only coming on under heavier acceleration. The wastegate is left bleeding exhaust so that the turbo only begins a good spool around 3,200 RPM - very late by Volvo's standards, but very good for fuel economy and reliability - so not even the turbo works hard. Superchargers last according to their lubrication and design. The one here is always getting fresh oil and is usually going to not be doing any work at all. On an engine with 200,000 miles, even with someone with a lead foot, the supercharger will likely only be engaged for 1/10th of that time - likely even less, since it is disengaged for cruise, coasting, light throttle, or high RPM... The clutch and the bypass valve are the only things that might prove to be issues, but these types of parts already exist and have a strong track record of reliability.

We found a very clean 2018 S60 T5 AWD (16,000 miles). But she missed the 5 cylinder Grunt at the light, merging and passing. I saw the T8 Version and was drooling, a 400 HP S60 would be awesome. We did get the Polestar ECU Upgrade and found 295 Ft Lb of torque. Yeah. But, You know More is Better. is there a chance to retrofit the SC part of the T6 into this T5??? Is the Electric Drive option also possible for retrofit of is all of this so complicated that would be impossible. I had no idea that Volvo was stuffing electric motors all over the place in the drive line. Makes me wonder if we could see Front wheel electric drive supplement for my 2014 C7 Corvette 9(,250 Miles) !!!!!!!!!!!!!!!!!! Wow! Cheaper than trying to trade.

I know this is an old video, but the T6’s have proved to have very few issues since it’s introduction. Some T5’s had oil consumption issues for a few years, but the T6’s are still functioning perfectly well. Proper maintenance is obviously key, but I have yet to hear from any other T6 owner that they’ve had a turbo or supercharger go bad. Even if they do, they’re both in very easy to reach spots. Not nearly as complex as you’d expect. As with any euro car, I’m expecting to do some sort of major maintenance when plastics eventually go bad, but 100k miles and 6 years have gone by and mine is still running like a top

Thanks Jason for another excellent presentation. This Volvo's engine, however, is ridiculously complicated and I'm not sure why the award... the weight of the car was too much for a 2 litre, 4 cylinder engine so they started adding up all that? Quite silly in my view... there are other options out there to move that huge SUV more efficient than this adding up engine. Definitely not the car of the future and for the common folk.

I think the engine is a good design but I would prefer this for the V40 and XC40 maybe the XC60 I just don't like the idea of a four-cylinder in big cars like XC90 and S90 that won't do any justice and probably won't drive as smoothly as a 6-cylinder or 8-cylinder like at least a 6-cylinder should be there for bigger models and a four-cylinder for smaller models The main thing here is for Volvo to bring the famous turbo five-cylinder for the Polestar lineup even if the five-cylinder is a hybrid it would still give a much better performance and sound than a four-cylinder

Having sat through the Volvo UK launch of the new engine architecture (they launched the D4 here as the first one), the diesel and petrol engines also share a lot of the basic structural design. Obviously different heads and slightly beefier block for the derv but they were keen to stress this was a ‘single engine architecture’.

[@victoro.velasquez8104]

1:45 great diagram 😃👍🏻 That's perhaps an award winning engine. But my 2014 v60 is the real ☠️ It's the T5 diesel D4. It's quite fast 👍🏻car but the engine is 👎🏻 It's going 128k miles it's burning oil. So I keep topping up every 100 to 200 depending on my driving style and distances. I heard that it's got a poorly designed piston rings which causes this high oil consumption. Also the engine had a major repair due to a severe oil leak at 110k miles. At the same mileage also started to display the engine warning light on the dash. Took it to a specialist garage and told me that egr valve and cooler is blocked or something. But I don't feel any loss of engine power. Now it's started to show the message " reduced engine performance" on the dash. So wtf is going on with this blo... engine??! Well I recently found out that this Volvo is fitted with a nasty Peugeot engine, hence perhaps it's breaking down slowly until it dies...😢 I love the car driving and versatility but it's heart is just so badly produced. Shame on you Volvo!!👎🏻 Good video mate 👍🏻

All very clever but it sounds like a bit of a nightmare to maintain. You can absolutely FOREGET any chance of easy DIY repairs when the car is older. Then again thats probably the idea....take it to the dealer or scrap it. Not really that economical in the long run IMO, far to much to go wrong.
