My parents had these cars when I was growing up. Plymouth champ, Dodge Colt vista, Dodge Colt. They all had double digit hp, nothing special, but they ran fine and cruised the highways at legal speeds just fine. There were times when we would go as a family of four in the car.
You really don’t need more than about 72 hp to drive anywhere across the country.
Had Colts ( 1.4 Ltr. , 1.5 Ltr. ) , a Champ ( 1.6 Ltr. ) and an '92 Eagle Summit ( 1.5 Ltr. ) . All had plenty of zip for the road . Favorite was the 1.6 Ltr. of the of the '82 Plymouth CHAMP . It also had the twin-stick which was a 4 speed manual with the shifter of Economy or Power mode ( lower gear ratio ) . Most were manuals . They were from '80 to '92 .
