Well - this rental Sonata is proving to be a tough and worthy "test mule"..
I will try get some vids - and at least post some pics later.
But so far - all attempts to get the car to self destruct have failed... it has a "manu-shift tiptronic-wannabe" auto box.. that wont shift to the next lowest gear until you drop your revs below about 2500rpm - and self shifts to the next highest gear at 6,200-odd rpm..
I spent morning with the car in 1st - and let the "self-preservation-shift" mod select upshifts at 6,200rpm (6,500rpm red line

) and then allowed it to select down shifts - although i still try force it into the next lowest gear.
If I find some deserted area/car park one day I may do some standing starts and break tests on video. ...
In summation - what a pile shit the car is... cheap - but even more crappy than a Cavalier... and for the price a smaller Corolla or Civic would be a better buy - they just "feel" better.
Your's truly - the "roaming road tester"...
