Love this car!
 I've read through all the reviews here and quite honestly,  I don't hear any engine noise. The car handles like a dream and the fuel mileage is fantastic. The steering is a bit loose compared to what I'm used to, but I like it. There is plenty of room for all my grown children and grandchildren.  The only thing that took some getting used to is the acceleration.  It accelerates from the current speed with little or no shifting. It takes off quickly, it's just the feature is not what you expect. Although I do enjoy it.Overall, it's a great car!
