Its 2630 mm wheelbase provides ample interior space, while the 1412 mm front and 1402 mm rear track widths contribute to its stable and balanced stance. The car's independent front suspension with spring setup ensures a smooth ride, while the disc front brakes and drum rear brakes offer reliable stopping power.
