FR-S/BRZ vs. Genesis Coupe

[OrbitalEllipses]

I need to dig-up the weight distribution comparison I saw over on NASIOC...

Couldn't find it, but here's an image the BRZ brochure. Specifically, look along the bottom edge of the car, above all the text.


55/45 innate distribution.

[SUB-FT86]

Where the hell is Scion getting 53/47 then?

[OrbitalEllipses]

Probably quoting the two passengers figure. I doubt it's actually more balanced.

All in all, when it comes down it, the FT86 project is kind of a let down by the numbers. Way overshot 2600lbs, innate balance isn't 50/50, hp is low, torque is lower. It drives great, but it wasn't what was promised.

I'll probably still buy one.

It's 53/47 with a driver and passenger (which adds more weight to the back than to the front). Probably similar with driver and some fuel.

55/45 empty seems about right judging from the proportions and engine placement. It's not that bad for an FR 2+2 (same distribution as the S13 240SX), given the modest power and reasonably light weight. Stretching the chassis to situate the engine further aft relative to the front wheels would have added size and weight.

But they should build a 2-seat sports car on the platform, with the front seats and engine/trans moved aft about 20". That'd be ~50/50

why would you want innate balance at 50/50? usually people get inside a car when they drive. also the car moves sometimes. those weight balance numbers dont mean anything as they close in on 50/50. hell, a car that light could change by upwards of 3% just by having a full tank of gas. and how is low hp a letdown when it has exactly how much the rumors said it would have? the only thing that could remotely make me think they missed the mark is if the price is of what was anticipated

2013 Hyundai Genesis coupe 2.0T will have 274hp. Its new design is more aggressive in my opinion. Has a great power to weight ratio I think I read 12.5 or 12.8lbs per hp. The interior is much nicer than the scion FRS. Also gets a slight MPG boost over the FRS/BRZ. The suspension is refined also.

I would think that two drivers would add weight in the middle to front of the car. The only way you can add rearward bias weight is by putting people in the back seat otherwise the weight would be in the middle.

If you look at the picture, center of the wheelbase is just right in front of the front seats. When we sit, almost the entire weight is on the seat. I think that's the reason F/R balance shifts from 55/45 to 53/47.

Driver and front seat passenger centers of gravity are definitely aft of the middle of the wheelbase, ~60% from the front wheels. Empty car c.g. is at 45% from front wheels. 2700 lb. at 0.45 plus two 330 lb. at 0.6 => 3030 lb. at 0.466, 53/47 F/R distribution.

I think we need to put up a profile picture so I can see that because I am not seeing it clearly

The image in this post illustrates it:

With the seat pushed forward to allow for a rear passenger, the center of mass of the driver is 185-188 pixels from the front axle and 149-152 pixels from the rear axle.

That puts the driver COG only 55-56% towards the back, but the seat looks like it can go back another ~25 pixels. It only needs to go back 12-15 pixels in order for the driver and front passenger COG to be 60% towards the back. That diagram's scale is approximately 3.3-3.4 inches/pixel, so you could still push the seat back another 3.5-4.5" past that point.

It's an old FT86 concept II image, but you get the idea.

I think the '13 2.0T is rated at 12.3:1 vs 13.7:1 (est) for the FRS/BRZ.

To be honest I would be an idiot not to consider the GC 2.0T. Depending on how the BRZ is priced, I could see myself looking at the GC. I love the idea of the BRZ but don't want to bend over just to have Subaru/Scion take my money when it is over priced.

I am in the same exact boat. I would love to have this vehichl but if they over price it then I am going to have to go to hyundai. That 100,000 mile warranty is looking too good. Maybe after a few years I will swap to a used frs/brz if my life allows it.

The FR-S/BRZ is 700 lb. lighter than the Hyundai. If you want a Hyundai G35, obviously the GC is the way to go. If you want, effectively, a 2+2 coupe version of a Miata, FR-S/BRZ.

Check out the overlay:


This *must* be exaggerated quite a bit, but you get the idea. The GC is quite massive relative to the FR-S/BRZ.

Personally, FR-S/BRZ all the way for me.
