    • A system and a method are disclosed for measuring the grip performance of a vehicle by interposing a load carrier member intermediate an upright and an axle. The load carrier member is configured as having a geometry for measurement of a magnitude and relative direction of the instantaneous load forces acting between the axle and the upright and includes a planetary bearing carrier received coaxially over the axle for linear movement therewith. The bearing carrier extends from an outboard first end to an inboard second end configured to define a force transmitting portion. A rotational bearing assembly is interposed between the bearing carrier and the axle providing for the rotation of the axle within the bearing carrier. A first linear bearing assembly is interposed between the upright and the bearing carrier providing for the linear movement of the bearing carrier relative to the upright. At least one force sensor is operably coupled to the force transmitting portion of the bearing carrier to be responsive to the linear movement thereof for providing load force output signals corresponding to the magnitude and relative direction of the load force vector. A magnitude and relative direction of at least one instantaneous load force vector acting on the load carrier member then is measured. Finally; the load force vector is resolved with respect to a relative plane into at least one load force component corresponding to an instantaneous grip force developed between the wheel and the ground surface.

    • A modular chassis (10) for a front engine rear drive motor vehicle is described which comprises as structural components a front structural member (A) attached rigidly and detachably to a tubular structural member (B) which is attached rigidly and detachably to a rear structural member (C) wherein the front structural member (A) comprises a structural member (A2) providing attachment points (30) for front suspension members (8) and an engine and supports the torsional, lateral and longitudinal loads created between the front suspension members (8) and the tubular structural member (B). The tubular structural member (B) is longitudinally disposed on the center line of the vehicle (10) between the front structural member (A) and the rear structural member (C) and supports the majority of the torsional, lateral and longitudinal loads created between the front and rear structural members (A and C). The rear structural member (C) comprises a structural member (C) providing attachment points for rear suspension members (9) and a transmission (4) and supports the torsional, lateral and longitudinal loads created between the rear suspension members (C) and the tubular member (B).
