I took test drive of both Grand Carnival and Sportage in June last year, tbh both are beasts having 6 speed triptronic gearboxes.
Take a test drive and you will fell in love with it, specially if you drive Carnival you will forget you are driving a minivan as its 3.3 V6.
Sportage having 2.0L engine 6 speed gearbox and features like cruise control etc. is a complete package for a family driving in cities and motorways mostly and occasional trips to North.
