so after watching more interviews i'm back on the fence about the i4 ... It was said the i4 has a Aluminum subframe vs a steel one for the v6 . also i heard they lightened up the i4 trans .. SO with the weight loss of the i4 and frame going to put it enough lighter to make up the power to weight ratio of the v6 6 spd . and will it balance the car closer to the 50 /50 ?
