Picked up our 2014 fully-loaded SX three weeks ago. Lots of research done before the purchase, replacing our 2011 Sonata which always felt big and ponderous and had a very harsh and jittery ride. Forte is a major improvement. Handles much easier and soaks up imperfections and bumps in a much better manner. The acceleration is excellent for us, with tested times 0 - 100 in the 8 second range with the 2.0 GDI engine. Sure the steering is still somewhat numb, but switching to Sport setting helps a lot in the enjoyment factor. Car is stylish, full of features not found on the Sonata Limited, rides nicely and so far in break-in mode (using paddle shifters to run in the 2000 - 4000 rpm range) we've averaged just under 9l/100kms, with mileage expected to improve as we let it rev lower now in auto mode now that the first 1000 kms have been put on.
Only disappointment is the air compressor and sealant instead of a spare tire! Purchased an aftermarket steel wheel and a full size spare. The sealant idea is a joke, since it often will ruin a tire if used and you still could get stranded for hours somewhere waiting for a tow. All to save about 30 lbs in weight and rip off customers. Many Kia's coming with this in the future, so buyer beware.
