The wheelbase of the car was only 75 inches, the track size was only of  40 inches and it was weighted 794 pounds. Due to its small size, it was named as “Baby Austin”. The car was equipped with four “in-line water-cooled” cylinders with the displacement of 747 cubic cm. The bore of the car was smaller than its stroke and the four side valves of this car model dribbled out ten -horsepower at 2400rpm.

The steering of Austin 7 was by the wheel and worm mechanism. The rear adjournment of the model was cantilevered by “quadrant elliptic springs” from the rear part of the car chassis.
