I have a Jetta 2.0 so loads of power it does not have. My immediate observation when I had these installed was that the car felt faster on take-off. Not talking corvette fast but it struggled less to get up to speed I was really feed up with this car lugging around its weight but I'm much happier. I'm not affiliated in any way with Bridgestone but the low rolling resistence of these tires are apparent. My rpm on the highway also dropped and I kid you not of about 1000rpm. Yesterday I had to do a fast launch into a intersection and was surprise to not here any slip, also should mention that I did the typical steering wheel side to side when I first drove on them and wasn't expecting that much grip at all from these tires! So in closing if your looking for a wicked deal tire for something with a weak engine so far I can't see how I could of made a better choice. I rarely review but always read then for this I had to. Good job Bridgestone hope you keep these going.
