^^^^Crude doesn't mean inefficient. (FWIW, I don't recall James saying the engine was crude). But, in this review anyways, I think we could say the engine is crude because of all the drivetrain noise that James's mentions. In that regard, I've found Suzukis I've ridden in to have a bit more engine noise and vibrations throughout. Though to be fair, I haven't been in this particular vehicle. So while the engine is frugal for a 6 cylinder, the NVH is what some might consider to be crude.
Fair enough. I didn't mean to imply that the current reviewer called the engine crude, but many other reviewers and people commenting on the GV have said that. I don't recall similar complaints when the same engine was used in the previous XL-7. The NVH may simply be a result of inferior sound insulation. To that end, I see on the list of changes for the 2009 GV is increased sound insulation. Indeed, I have a roll of "Ultimate" I bought from b-Quiet waiting for me to have time to install it in my GV.
Other than a slight, and not unpleasant whining sound I hear sometimes, I wouldn't say I hear anything else from our GV's drivetrain. I wonder if the one tested had either the infamous rear end misalingment, or the infamous drivetrain vibrations - either of which presumably could cause driveline noises.
I thought Jame's review was refreshingly fair to the GV's unusual combination of characteristics.
