It could be that but the most obvoius reason would be incorrectly inflated tyres - have you checked them recently?

If this is not the problem, are there any other signes that something is wrong?

check the air filter, could also be the brakes binding

how long since the spark plugs were changed?

If its got a turbo its probably a diesel so no spark plugs.
