I was out of the country for the month of May but when I came back in June, I've seen TONS of them here in socal. Before that I never saw them.

What numbers would a Direct Injection LS3 put down?

[Mr. Wyndham]

OOOH....wait...I don't care, it's still a terribly ugly vehicle.

iirc, Hyundai was INSISTANT that the coupe could not harbor a V8.
Why the change in attitude, because sales..."stink"?

With a higher compression ratio AND revved to the moon like these little pests? I'd put my money on 500+, easily. Add headers and a Cold Air intake like Ford did...you're looking at 550.

The question is whether such an engine can pass emissions...which is likely a "no". The Generation V engines are coming, though...and in a big way.

The way I look at it, the LS3 is based on "old tech" compared to all these new engines...yet it's still just as, if not more powerful than all of them. Imagine the next generation...

I'd say a DI variant of the LS3 should be good for ~500 hp, give or take.

But don't expect that the DI engines will stay the same size as the current crop of V8's. I've got a gut feeling that GM will go back to using 5.7L engines as their mainstream V8's.

the genesis seems like a girls car to me, I would wayyyy rather have a 370z

It seems like Hyundai has just been trying to follow the Mustang's specs.

Can't go wrong with 5.7

[SleepWarz]

The true win would be having a wide spread of options... LS3, DI 5.7, LSA..... Omnomnom

[Sax1031]

I can't believe they have waited this long to offer a v8 in the Genesis.

Direct Injection in and of itself is not worth that much improvement in hp.

not going to happen. LS3 will be obsolete. How long did GM keep using LT4's once the LS1 came out?

[305pride]

i think that Americans shouldn't be the only ones having fun with muscle cars

[Rallysport]

Sorry...I have never seen a korean car design worth a spit. The trend continues. Hideous.

My guess is that they were telling the truth when they said it doesn't fit, and if we see a V8-powered Genesis coupe it wont be in this generation.

I think the 500+hp estimate is doable, but touching on your emissions comment if it could be produced in an emissions-satisfying trim at that power level my money says it would suck gas like nobodies business. Look at how much petrol the LS7 sucks down compared to it's lesser brethren even with 7.0L of displacement. A production trim, 6.3L version of the same basic engine that produces as much power probably wouldn't even manage a rated 20mpg highway in a Camaro.

Also worth mentioning, Direct Injection almost certainly isn't going to bring as much to the table with the pushrod V8 as a lot of folks are hoping because one of direct injections most troublesome shortcomings was overcome in part by using one of the inherent advantages of a DOHC design. Put simply naturally aspirated, DI engines still technically suffer from fairly serious drive-ability issues under certain fairly specific conditions, you just never encounter that problem because you never see those conditions while driving. The really abridged version is that you end up with some fuel/air mixture issues that cause problems with the combustion process and, the next thing you know, you're mega bucks, DI V8 is 100hp down on power and running like a 9N Ford tractor.

The reason you don't see this in the DI DOHC engines being produced right now is because they have literally programed the engine system to run around the problem. You're driving down the road, approaching a scenario where engine load, rpm, etc, etc are all going to merge perfectly to create the above mentioned problem and presto-chango the camshafts swap profiles, the timing changes, and the problem never occurs and all the while you never notice that anything happened to prevent it.

One of the problems with the implementation of DI on pushrod engines thus far is that you simply can't fix this problem in that same way because there just isn't enough room on the one camshaft a pushrod engine uses to employ the same level of variability two intake and two exhaust camshafts can provide for obvious reasons. And since that is exactly how virtually every other company on earth fixes this problem that creates a problem. My guess is that all the buzz about a cutting edge combustion chamber has something to do with this, but I will be curious to see how well it actually works at solving these issues.

Throw in the fact that DI by itself is really only a 5 percent or so improvement on a DOHC motor on a good day and I think this is an area where what the average GM enthusiast wants this to mean and what GM is actually using it for are two different things. My guess? The advantage GM is looking for with DI is the ability to run higher compression in a smaller, pushrod V8 so they can downsize the engines in the search for better fuel economy without losing very much in the way of power production.
