Re: Performance difference between Wk & WK2?
WK is 'faster' than WK2 (the following refers to a limited model with 5.7 and 4x4)
WK has 330hp from 2005-2008, 2009 and 2010 have 357hp
WK2 has 360 HP
WK has 3.73 rear axle ratio WK2 has 3.47 (making it slower)
WK weighs roughly 4700lbs WK2 weighs 5150lbs
A big thing I've noticed though with my new WK2 I picked up last weekend is that the power delivery is much smoother and more refined, I had a 2007 and the electronic throttle lag is brutal in those things compared to the WK2 where there is practically not lag at all.
One thing that is really good about the final drive ratio however is that at 120kmh it will only be running about 1600rpm which makes for better mileage, the WK would be above 2000rpm. I would get 16.5MPG before at that speed, now I get 19.5-20
