I share your point. However, since the Cruze as basic car chassy and body structure built for a standard engine/transmission front wheel drive car, the idea of studding a 400 pound battery, generator and engine with all new control/electrical systems may have made the cost of assembling the car difficult and the cost of making the parts higher (to fit a particular place). I know the battery was t shaped because it had to fit into the center Hump between the driver and passenger. Maybe making a square battery is cheaper and more reliable (the battery is liquid cooled and the circulation maybe nore even in a square box versus a t shaped box). I doubt GM would lie that is is cheaper to build a purpose built car.
