Which car is faster........................…
Stock vs Stock?
The Essex V6's 180 hp is somewhat optimistic. I don't think it's that high in reality.
If my 170 hp Integra can hand an Essex 3.8 it's @ss, then the Celica is going to stomp a mudhole in said @ss.
The Cobalt does not belong in this equation. Unless the Cobalt comes to the party with at least the 2.4 SS, a supercharger, or a turbo, it's better off playing with N/A D-series 1.6 Hondas.
