Been here awhile...
Yes, other than a couple times I have never used or required the power of the 4.6, the trade off for reduced fuel economy does not outweigh the occasional thrill of showing off in my opinion.
I've said this on other threads before so sorry for the repeat for those who read it already.
I had a 3.8 Genny and a 4.6. I preferred the 4.6 for all the reasons stated above.
In 2009 when we bought the first Genny, my husband wanted the V8 but I balked because I thought I'd get better gas mileage and so we purchased the V6. The second Genny was a V8...had I known that the difference in mileage would be so negligible, I would have gotten the 4.6 in the first place.
NOLa
In 2009, I went with the 3.8 Premium Plus for the value. Paid $32K. You simply can't find another new car for that price that comes close to the size, features, etc.. of the 3.8 Genesis. If forget what the uplift in price for the V8 was at the time, but it was not insignificant. For me, the "upgrades" did not justify the extra expense.
For 2012, the base price MSRP difference between the two is $10,300. That is a huge difference. Roughly a 24% premium to go from a v6 to a v8. For some it may be worth it, but for me it's a no brainer. Not even close.
Just my opinion, but the dollars speak for themselves.
BTW, go back and read the 2009 era car reviews. Many of them stated the same thing. Not worth the cost to upgrade. Much better value as a v6.
I actually think the stock 17" wheels are the best looking, although they are a little small.No regrets, I like the power which my wife and I use often around Atlanta, the brakes are larger with 4 pistons and braking is great. I like the 18" V8 wheels vs. 17 or 18 V6 wheels, the chrome on the doors, the better headlights, and the fact that the Tau V8 engine has hydraulic lifters while the V6 has solid lifters that will require more maintenace as the car ages. Oh, and also I perfer the German made ZF transmission that comes with the V8.
The V8 was the reason I bought the Genesis. I originally started looking at the G8 GXP until it went away. Then it was the E550, 550i, GS460 or M56, all as CPO purchases. The Genesis 4.6 was the answer to getting what I wanted, new and at a bargain. Frankly, a V6 was never even considered.
Wow, I could have written that paragraph.
