Of course a Sonata sounds bad and shifts a lot, and the Hemi sounds good and doesn't shift much because it can't. So the Hemi feels better. But fast it ain't.

That's a complete crock of shit. Tell yourself whatever you want to justify your decision to wait, but don't start posting BS performance comparisons.

0-60 with the Hemi is 8.0s, with the 4cyl "rental" Sonata it's 9.2s. That's a significant difference.

I read 7.3s... the Hemi feels pretty strong to me and I have not pushed it too hard yet (only 300miles). I'll do the ESC update next week for a more better throttle response. I hear it makes quite a difference.

Is that TSB 18-001-11? ESC

I never trust C&D's 0-anything times. They always have different time than other mags for the same car.

Re: Underwhelmed by HEMI

LOL at the Sonata comparison. Load up the Sonata with four 200lb guys and then do the same in the 5000lb Jeep and do a comparison. The Sonata will fall way behind. Although many if us lament the weight and gearing of the WK2 in that it doesn't help performance, what it DOES do is make the performance difference less noticeable when it's loaded with passengers and gear compared to when it's only carrying the driver. I would bet my jewels that a loaded-down Sonata would be quite the pokey vehicle compared to a Hemi WK2 loaded the same way.

On paper the Hemi is a beast. In practice, it doesn't knock your socks off like you would expect. Compared to a 4.7HO WJ you would never think the Hemi had 100 more horses. If anything, you'd think it was down 40 to the HO from stoplight to stoplight. Gearing, weight, and programming all come into play here.

Re: Underwhelmed by HEMI

at the Sonata comparison. Who remembers the guy clocked by Arizona speed radar at 144ish mph in a sonata. A ton of people said it was impossible to do.

C&D did a test to prove it could be done, but on a slight downhill.
