None. Not one is "smooth to drive" because they are all trucks with leaf sprung rigid back axles capable of carrying at least one tonne. So they all bounce about a bit and crash over speed humps. But the fastest is the new Nissan Navara with an all-new 235PS 3.0 litre 65 degree V6 diesel that it shares with the Infiniti EX30d and Renault Laguna coupe. Auto is optional. My personal preference is for Isuzu D Max (Rodeo) and Chevrolet Colorado because they have amiable four cylinder chain-cam diesel engines and the best transmissions (I've got one of each). L200s handle best. HiLux are still all belt cam.
