Horsepower and aerodynamics
Horsepower is the energy output of the engine. More horsepower = more energy. This does not, however, mean faster, or better acceleration. Not all of the energy produced by the engine will make it to the wheels. Most is lost in the form of heat. Torque is what will push you back into your seat.

There's a tie between cars with the least horsepower. Both the 2014 Mitsubishi i-MiEV and the 2014 Dodge Avenger have the least amount of horsepower.
