Unveiled at the 2013 New York[72] and Frankfurt auto shows,[73] the second generation Soul is based on Kia's Track'ster concept,[citation needed] and offers an increase in torsional rigidity of 28.7%, wheelbase increased to 2,570 mm (101.2 in), width increased to 1,800 mm (70.9 in) and the same overall height of 1,600 mm (63.0 in). The redesign features a wraparound greenhouse, high-mounted tail lights, large trapezoidal lower air intake and "floating" body color panel set into the liftgate. The second-generation Kia Soul shares its platform with the second generation Kia cee'd hatchback. 66 percent of the chassis utilizes either Ultra High Strength Steel (35 percent) or High Strength Steel (31 percent). The front subframe uses four bushings (the first generation has none) and the shock absorbers on the rear torsion beam axle are now mounted vertically allowing for more suspension travel.
