A 5.0 Liter V8 Coming Soon To Infiniti ? (+ future Infiniti line-up)
#31
Just in case you didn't realise, The infiniti engines have usually been larger displacement.
Nice of you to waste your sunday afternoon to show us all those details, but output is hardly the be all end all of what makes a good engine
p.s. Thanks

True, but until recently (i.e., the introduction of the Lexus 3.5L V6 and the 4.6L V8), Infiniti engines (i.e., the VQ and the VK) have been in general superior to their Lexus counterparts. IMO of course.

Hmm, let's take a closer look by each year:
1990
Flagship V8: LexusLS400 (250hp) vs. Infiniti Q45 (278hp) - Advantage = Infiniti

2000
Flagship V8: Lexus LS400 (290hp) vs. Infiniti Q45 (266hp) - Advantage = Lexus
Executive Class/Entry Level V6: Lexus GS300 (220hp) & Lexus ES300 (210hp) vs. Infiniti I30 (227hp) - Advantage = Infiniti
2001
Flagship V8: Lexus LS400 (290hp) vs. Infiniti Q45 (266hp) - Advantage = Lexus

Executive Class/Entry Level V6: Lexus GS300 (220hp), Lexus ES330 (225hp), & Lexus IS300 (215hp) vs. Infiniti G35 (280hp) - Advantage = Infiniti
So, using the best V8 & V6 options each brand had to offer per year for model years 1990-2005, here are the results:
Flagship/Executive V8 = Infiniti has had the more powerful V8 in 12 of 16 model years.
Executive/Entry Level V6 = Lexus has had the more powerful V6 in 8 of 15 model years.
So while Lexus has had the slight advantage in the V6 department, Infiniti has clearly had the advantage over Lexus in the V8 department.

"Superior is relative". Lexus engines generally have been more refined, and more fuel efficient than any comparable Infiniti engine. Infiniti engines also over the years have been criticized for having inflated HP numbers.

I really was trying to avoid this thread before the fanbois dropped in and probably will link this thread to Ghosencostcutting.com and cry foul.
Here is what YOU said;
So I post my facts and then you PROVE my point with your post that took you all Father's Day to post.
So thanks for proving my point And your buds clapping, didn't read what YOU said. lol
Again, I post the VQ is a fantastic engine. The Q45 outside the 2nd gen has always had a great engine.
The amazing thing is they have more power on PAPER but the LEXUS is usually faster. The LS 430 was 50hp short and faster than the Q45. Currently the IS 350 with the same power as the G35 is faster. The GS 430 is pretty much on par with the M45 and its 35hp short.
Both companies, IMO make FANTASTIC engines, pretty much always have. Clearly, I am more impressed with the Lexus ones.
Today, its not even close. Lexus engines are more advanced and I posted the huge difference in engine choices.
With that said, I am exiting this thread b/c we have been down this road too many times and I am going to avoid it.
Here is what YOU said;
Are you suggesting the Lexus 4.6 will be more powerful or simply "better" than the Infiniti 5.0?
Because given their history, Nissan/Infiniti has always been the one with the more powerful engines. Only until the recent 3.5L which has made its way into the GS350, the IS350, the Avalon, the ES350, & the Camry has the power field really been leveled by Toyota. I can't recall a single engine before 2005 where Lexus had a power edge over Infiniti.

Well, as you exit this thread, let me just clarify that I did in fact say "I can't recall a single engine before 2005 where Lexus had the power edge over Infiniti". However, when I made that statement, I was mainly referring to the most powerful engine either brand had to offer, which would be their V8s (as that is what this thread pertains to). We were discussing Infiniti's upcoming 5.0 Liter V8, thus my comments. If you look at the list I provided, the V6 offerings from both companies have been pretty comparable from the beginning. There's been a slight edge for either company at any given time, but the V8 (the most powerful engine offered by either brand since 1990) has favored Infiniti 12 of 16 years. I broke it down and added the additional information on the V6 offerings, just because.
Anyway, both companies do make fantastic engines and I'm sure they will continue to do so. The new Lexus 4.6L is amazing and I'm sure the new Infiniti 5.0L will be comparable.

Q45 will be missed, one of my favorite cars. It's generally believed that 1 reasone Infiniti never hit the spot was due to their entry ad compaign. They never showed the car, which put off a lot of potential buyers. Engine wise, the Nissan Corporation seemed to always have a spot on Ward best engine list, based on power, refinement and reliability. I was a 5x maxima owner myself and generally love Infinity because of out of the cookie cutter way they built the cars ie, J30, Q45 (1St Gen). I think with the right marketing compaign and a great design,ie, G amd M series. I can say that can make a come back. Good Luck Infiniti, heres one guy in your corner, umm, wearing a Lexus Pull Over. LOL.
#38
Well since you're gone, maybe someone else can elaborate on "why it's not even close". So far that's only rhetoric. It always amazes me that here a thread about Infiniti (in particular) eventually devolves into a "Lexus is superior" thread.
#39
I'm not quite sure why this is the case, but I do want to point out that Infiniti pretty much started the trend toward 330+ hp V8 engines back in 2001 - before any of the competition was even close to reaching that. So since 2001, Infiniti has pretty much been using the 340hp & 335hp versions of that same original VK engine. But this is not a new engine. It's a 6 year old design that still matches up well to the competition to this day, while the other companies have now released their new engines.
But let's not forget that Infiniti was the first to start this trend back in 2001. I have no doubt that once the new 5.0L V8 comes out, that it will once again set the standard for power in this class.

I wouldn't be so quick to jump to conclusions. If the rumours are true, then a 390HP 5.0L Infiniti V8 certainly will not set the standard for power in the class, as several V8 engines from the competition will have power figures that exceed that number.

Regarding your second statement: I believe both companies make excellent engines. I have experience with both engines, as my dad owns an 06 Lexus GS430 and I own a G35 coupe.
I believe the engines in Lexus are more refined; they are usually quieter and don't have that "sporty" sound and feel to them. Great engines nonetheless.
As far as the VQ's: I believe they have a better feel only because I prefer engines that have a noticeable tone to them, and have other sporty characteristics.
They are both fantastic engines in their own way.

The 4.3L Lexus UZ V8 compared well with the Infiniti engine. The Lexus UZ also is an older design than the VK.
I wouldn't be so quick to jump to conclusions. If the rumours are true, then a 390HP 5.0L Infiniti V8 certainly will not set the standard for power in the class, as several V8 engines from the competition will have power figures that exceed that number.

What other V8 that is within the same class as a Q or an M currently exceeds 390hp?

One thing is that Lexus has way deeper pockets than Infiniti, and it shows. Our cars are packed with far more technology than their Infiniti competition, because pioneering such innovations costs lots of money as we all know. One of these areas is engine technology, where Lexus clearly has the upper hand.
As someone else mentioned, the performance and evaluation of an engine has a lot more to do with packaging and application than horsepower numbers. The 1UR-FSE displaces only 4.6 litres and makes 380hp. That's 82.6hp/L as compared to Mercedes at 69.45hp/L or 75hp/L from BMW. Such efficiency on the Lexus engine is admirable. Also consider that the UR has direct injection and VVT-iE, things that aid power, power delivery, and gas mileage. Another noteworthy remark is that the LS is capable of ~29MPG (see LS460 forum) when driven passively, a feat that no other V8 has been able to nearly match, despite it's impressive power output. Lastly, consider that the engine is mated to an eight speed automatic, which allows greater acceleration through increased gear changes and also the transmission contributes to such superior gas mileage when cruising.
I am not stating that Infiniti cannot build a comparable V8, but they aren't a company that has typically led the industry with fantasitic drivetrains, then again, Lexus was not either until recently but they thankfully have Toyota's financial backing to invest in such technologies. I had read recently that Infiniti would be employing direct injection in their next generation of engines, so hopefully that is fact and not just a rumor.
Considering Infiniti: Lots of power on paper? Yep. Pretty good acceleration? Definitely. Class leading transmissions? No. Superior gas mileage? Nadda. That said, their powertrains are typically not cutting edge, and it seems that Lexus has thrown a yardstick with the UR V-8 and if Infiniti does come close to matching the power, performance, and fuel efficiency of the engine then it will be a very admirable feat. Not saying it cannot be done, but it will require an amount of R&D and $$ that it doesn't seem like Infiniti has been capable of before. That said, if the new Q is to succeed, it needs to be unlike any Infiniti before
