Gear ratios play a significant role. All 5 speed vehicles (Charger, 300, GC, Durango) lack a real first gear. SRT's are exception because of an aggressive final drive ratio.

According to C/D data, that's not the case, although Taurus have more agressive gear ratios, at least until the 8 speeds come.
Overall gear ratios:
........Taurus........Charger
1st.......14.2............11.0
2nd........9.1.............6.7
3rd........5.8..............4.3

Gear ratios difference is even greater between Explorer and Grand Cherokee (V6 vs V6, EcoBoost vs Hemi)
Overall gear ratios:
........Explorer V6 AWD........2013 G. Cherokee V6.....2014 G. Cherokee V6
1st..................15.18........................ .....10.98.........................16.25
2nd...................9.73........................ ......6.70..........................10.83
3rd...................6.24........................ .......4.31...........................7.24
It's similiar for the Ecoboost vs Hemi.
