Yes, I think so as well. Here the 3.5l is the only engine option, also some of the features are different here. My car for example has ventilation on both driver/front passenger seats, the audio remote control on the rear arm rest etc. but then again the lane departure warning and advanced smart cruise control are missing.
Anyhow, I am super satisfied with my purchase after 5000km. I test drove most of the competition available here: Toyota Avalon, Mazda 6, Hyundai Azera, Peugeot 508, Honda Accord, VW Passat and Ford Taurus. The Cadenza was by far the best out of that bunch atleast.
