God I hope not! While engineering does continually evolve, it seems every time that a manufacturer starts chasing the high-output HP, fuel economy suffers big time. I'd much prefer around 265hp with better MPG.

Replying to: backy (Jul 09, 2009 6:18 pm) Hyundai should have the technology to bump up the V6.... The Tau 4.6 liter V8 produces 80 HP/Litre (368 total), so using that formula they should be able to bring the 3.8 engine up to 304 HP.

Replying to: bman900 (Jul 09, 2009 7:34 pm) I agree with the earlier post though re why not use this technology to improve FE even more by keeping the output down? Surely there is a trade-off for power vs. FE at some point. It begs the question as to whether Hyundai would ever go the hybrid route with the Genesis V6 sedan, using the lithium polymer batteries and other technologies they are developing for the Sonata et. al.

Replying to: backy (Jul 09, 2009 7:45 pm) The Genesis engine is designed to be smooth and deliver nice power lower in the RPM range. The G37 needs 7000 RPM to deliver 330hp, and it's no smooth operator at that speed. Hyundai could easily tweak the air/fuel ratios and cam/valve timing to bump the peak HP a few points. But, just like every other manufacturer, they'd just be robbing Peter to pay Paul.

Toyota's 3.5 is the probably the best V6 out there (especially in direct injected form). As for the transmission in the Genesis, its made by Toyota anyway. It suffers from the same crazy shift logic that is geared more toward fuel economy than anything else.

Replying to: backy (Jul 09, 2009 7:45 pm) I'm not a great fan of hybrids, not in their present form. I think they're gimmicky and false economy, but that's another subject. I am hoping for a clean diesel option for the economy minded. A 5 or 6 cylinder turbo diesel would be plenty motivation for the Genesis, and would easily outlast the 10/100 warranty. I highly doubt a hybrid's expensive, consumable batteries and electronics could be covered by the 10/100. I can see a Genesis TD with 6M, 6A, or 8A with FE near 30mpg with acceptable 0-60 times for most drivers.

Replying to: tjc78 (Jul 10, 2009 4:29 am) Some of the magazine road tests have reported the Genesis 3.8's zero to sixty time at six seconds flat (Hyundai advertises 6.2 seconds). That is really hauling for a 3,750 pound car! I agree that the Genesis ECM computer is tuned for mileage during easy, low-speed takeoffs from stoplights, etc.and it tends to shift at very low RPM's. I would prefer it to be a little less anxious to reach third gear for economy's sake. Once it reaches third gear, I like the shift pattern from there on.
