Hi,
I love it, I don't leave it on all the time but I enjoy using i when I'm in a more spirited driving mood or when jumping on a highway.You will notice fuel economy decrease when using Sport Drive as it will hold the gears a bit longer to get more out of the car....or it could just be the fault of the driver pressing the right peddle a bit more
. The manual shift mode isn't too bad either, it responds well to inputs from the driver compared to a few other vehicles I've used the same feature on. I drive a manual car in the summer and sometimes I just need that same fun factor in winter. The sport drive and manual mode do a pretty good job.
