Anyone else think the Tau v8s were Hyundai's best engines of all time?

I love my 5.0. It's smooth, powerful, gets pretty decent gas mileage, and so far has been pretty reliable. However, I am also worried about parts availability. My car has been at the dealership for a couple of months waiting on a part. Some of this may be lingering supply chain disruptions from COVID, but I suspect that an uncommon, discontinued engine like the 5.0 will not be a top priority when restoring supply chains. I am also considering selling my car once I get it fixed.

I read you posts about a simple transmission coolant hose connector being back-ordered or discontinued. I am really starting to lean more towards dumping my Genesis. It looks like engine is not very popular at all with the aftermarket and even Hyundai seems to be turning its back on the engine as well.

I may just go with an luxury brand that actually make replacement parts for it engines. I gave Hyundai and KIA a chance and both companies seem to be not the best at long term ownership pass the 100k miles warranty period. The companies do make nice cars when they run properly, but they are not good with the details like quality control and part supply.

However, I really really do like my 2015 Genesis 5.0 Ultimate, so I may try to give the company a chance to start producing parts before I dump the brand.

I watch this guy videos of engine tear downs and he finally tore down a 4.6 Tau engine with 150k miles from a wrecked 2011 Genesis. The engine was basically as good as new even though it was not maintained well when it was running and was left outside. The guy in the video stated the engine barely had any wear.

The Tau engine seems like an engine that can run well pass 500k miles if properly maintained.

I am looking to buy a 2015 5.0 Ultimate with 175,000 kms on it. Thoughts on the reliability past this point? For less that $12,000, it seems like a steal. Thoughts from fellow owners?

There’s a guy who has a 2012 5.0 RSPEc with like 190k and he has not babied it and it’s still going strong.

As long as it’s been taken care of, it should honestly be fine.

I've owned three 4.6 Taus, and they've all been great cars.
2009: owned 2011 to 2014, daily driver 60k miles
2012: owned 2014 to 2023, daily driver 70k miles
2012 (2nd one): owned Oct. 2023 to present, daily driver 6k miles so far.

The 4.6 is one of the most reliable AND efficient (hp/cu-in) engines ever made by anyone, and blows away just about everything else compared to what was available in 2008 when it first entered the market. I can easily sustain 21mpg in mixed suburban daily driving. Try doing that in any other v8.

Yes, it seems our 2012 4.6 gets 25 mpg on the highway at over 70 mph.

Title? I certainly think so. They were just really good engines. They had good performance with decent efficiency, were really smooth and refined, and they were some of Hyundai's most reliable engines, especially the 4.6. I am certainly sad to see them go, and it honestly makes me want to 5.0 swap a 2023 G90.
Any thoughts are appreciated! Have fun discussing y'all!

I’ve driven a buddies 4.6 sedan and it’s really nice. Tbh I still prefer my 3.8 lambda. But definitely get it with a zf8 trans. Mine asin is likely not to last long.

I have owed a 4cl Elantra, a 6 cyl and a 4 cly Sonata. A 6 cyl Santa Fe and now a 4 cyl Genesis. I never had an issue with any of them other than a thermostat that went on the Elantra at about 60,000 miles, which to my surprise, was replaced under warranty. So for me, all the engines have been pretty good. Actually, I can't remember having any issues with these cars period.

I have the same Elantra, it's a great car.

Guys my 2018 g90 5.0 has a knock when putting her under load like going uphill (detonation) and she's driving me crazy i did walnut blasting for the intake valves and cleaned carbon on the pistons with a chemical you take the fuel pump connections off and atach them to this device that injects the chemical and the engine runs on it and it claims to clean the pistons from carbon, after all this mess the engine still has detonation.

Does it matter what gear you’re in, or what your speed is?

 

[yazeed]

Does it matter what gear you’re in, or what your speed is?

It happes in higher ratio gears and when the rpm is low and you're accelerating like when she's in 3rd at like 1200 rpm and you hit the gas she starts knocking really bad or if i'm cruising with the cruise control on with lower rpm's and start going up hill she'll also do it.

 

[yazeed]

No specific gear or speed it happens only when the engine is loaded and in lower rpm's

Hmmm... What are the chances of the Tau returning or a newer V8 being designed now that environmental regulations are being rolled back? Automakers like Mercedes have already committed to bringing back their V8 and V12 cars. They realized nobody wants an AMG 63 car with a 4cyl... lol

I'd say the chances are next to nil, because these automakers just don't trust that the regulations are going to stay heading in the direction that they now are.

 

[LBTX]

I'm not a betting man, but I wouldn't be surprised if they bring back a V8 at some point. I'm sure they are watching BMW and MB and see that there is still an interest in the V8. We might even get to a point where they start to simplify cars again - i.e., no door handles that pop in and out. There was a decent article last week about people becoming upset by how complicated cars are becoming and the door handle issue popped up.

 

[SuperKing]

Volkswagen has committed to bringing back physical buttons... touchscreens suck. Yes, I agree that seldom used features don't need physical buttons but not everything should be in a touchscreen menu. I don't need a button to bring up my TPMS readings but opening the roof shouldn't be buried 3 levels deep. There was nothing wrong with reaching up and hitting a button.

It wouldn't surprise me if Hyundai is testing prototype V8's. It's always good to try things out and see if they work. BMW is famous for prototyping V6 engines once in a while but they never make it into production because they're just not as smooth as an Inline 6. It doesn't stop them from trying out ideas here and there to see if they can make it work.
