Abstract: A chassis constructed according to the invention includes a main frame and at least two breakaway subframes on which are mounted the left and right front wheels and associated suspension components. The main frame narrows forwardly. It has a midsection and left and right sides that extend from the midsection to a forward end of the main frame, the forward end being less than one-half the width of the midsection, preferably a near point. The rearward portion of the main frame is preferably also pointed, with two additional breakaway subframes for the left and right rear wheels. Breakapart components hold the subframes on the main frame so that each subframe will separate from the main frame if it is subjected to an impact of predetermined characteristics. Breakapart linkage coupling components connect the steering linkage to the front subframes while shaft coupling components may be provided for coupling rotational drive components to the subframes.
