There are two things I noticed in the first video (Santa Fe) that I can see are hurting 0-60 times. First, the transmission shifts are lazy. It's obvious Hyundai designed the shifts with grandmothers in mind.
Second, the car is shifting about 1,000 rpm shy of it's redline. Now, this may be intentional, as most small displacement engines with turbochargers run out of steam early, but it's causing the third issue.
Third, the transmission is forced to shift into third gear before it hits 60 mph. Three shifts 0-60 mph with a slow shifting transmission will kill times. Hyundai unfortunately choose odd ratios when designing the tranny...
However, I would definitely agree...considering all of the above issues, the additional weight of the AWD, and the 600 lbs of "stuff" onboard...the run was not terrible. In fact, it was still 1.1 seconds faster than what Motor Trend recorded, and I firmly believe, may even be good for a 7.5 second, 0-60 run.
I would also think the FWD would be capable of 0-60 times in the low 7 second range, perhaps even crack into the 6's.
If this Hyundai was a GM or Ford with a fan following, an aftermarket company would create a simple transmission re-flash that would fix the sloppy shifts, and an ECM upgrade that would help the engine create more boost and power. Unfortunately, this will never happen.
