  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Will there ever be a next generation R-Spec?

The previous R-Spec was never really performance oriented. It was more meant to compete with the hemi V8 300C, not the 300C SRT-8. The gearing in the car was gas mileage oriented, which severely limited the speed of the car and the suspension was just "sport-tuned" compared to the standard Genesis suspension. The R-Spec and cars like SRT-8s and Hellcats are aimed at completely different markets.
 
While I totally agree they're aimed at different markets the one thing that really stuck out to me was that with a supercharged 6.2L and in the same weight range as the Genesis it still kept up on gas mileage.

Supercharging is going to help with mpg a little. The main thing is: What's required to move the car around town? For similar weight vehicles the answer is about the same amount of power. So if they are seeing similar numbers I'm not too surprised - the supercharging is making up for the larger displacement.

The real difference is going to be when you step on it. I have a lead foot for accelerating (not speeding) and mostly drive in town. I'd almost definitely see single digit mpg with the Hellcat. I mean that thing can drain it's fuel tank in 13 minutes if you're fully on it, I doubt the Genesis could even drain 1/4 of its tank under the same conditions. But then again you wouldn't be going nearly as fast!

To answer the OP's question, yeah I'm sure there will be a 2nd gen R-Spec at some point. Took a couple years the first time and I wouldn't be surprised to see it show up around the 2017 model year, if they follow the same pattern they did with the initial Genesis release and first R-Spec.

I have to admit, I'm really curious to know what a 5.0 with a modern twin scroll turbo would be like.

Supercharging does not generally help gas mileage. Superchargers are a direct parasitic loss. They're mechanically driven by the engine that costs both power and MPG (they of course still net power from the boost). This is one of the factors in considering turbo vs super. Now there are exceptions, if you're towing a boat on the freeway you may see more gain from being able to run in a higher gear than you lose parasitically.

I agree on the 5.0 with a turbo though, that would be great. Supercharger whine alone would be enough to keep me away unless it was a dedicated track car or something, certainly not acceptable as a DD for me.
