Volkswagen is taking another Jetta to Bonneville, this time a non-hybrid.
I saw several articles on this car; some, like Jalopnik, erroneously report that the modified Jetta achieves Cd .27. However, after seeing other sources, like Autoweek, report the unmodified Jetta at Cd .27, I searched Volkswagen's own press kit for the 2019 Jetta and found that that's the number for the street car.
This looks like all the aerodynamic modifications we'd expect: no mirrors, lowered, solid wheel covers. Similar to the 2013 Jetta Hybrid LSR.
