Today went to test drive the K5 with my friend who is looking to buy a new car, tested the Camry, Accord, Sonata and Teana, so want to know how is the K5. Inside the K5, as usual for d segment, spacious, but seem like the K5 is a bit like the Sonata, rear headroom is bit tight for a tall guy, leg room is ok. But one thing that really impress me is the gadgets, damn a lot of gadgets that those Japanese can't compare. Riding quality is quite the the same as the Sonata, the rear is a bit hard to control, when turning into a corner with average speed, the rear side seem like reluctant to follow and you tend to lose confident for high speed cornering, this problem also facing by the Sonata as well. When drive thru those uneven road, this K5 seem like can't absorb it well and causing the whole car become unstable, something like riding boat. This problem also very obvious on the Sonata, seem like the Kia shared the same platform as the Sonata, and everything the Sonata did bad, the K5 also doing bad. I think I'll find another day to test drive again.
