With the require for smaller and bounteous fuel efficient cars growing in the late-1980s and early-90s, Common Motors needed to receive into this marketplace. It did this by entering a Seam Treaty with Suzuki to fabricate the Geo Underground.
Horsepower
The Underground had distinct engine options in it eight agedness under the Geo epithet. With the changes the Metro underwent, the fuel mileage change greatly. The base engines ranged from 30 to 53 mpg in the city and 34 to 58 mpg on the highway. The "high-output" engines got 30 to 46 mpg in the city and 34 to 50 mpg on the highway.
Both of the Metro's engines--from 1989 trough 1994--produced 58 pound-feet of torque. From 1995 through 1997, the Geo metro's base engine produced 58 pound-feet of torque, while the "high-output" produced 74 pound-feet.
Economy
When designing the engines for the Metro, the main concern was fuel economy. From 1989 on ice 1994, the imitation 1.0 litre produced 49 horsepower (hp) and the "high-output" engine produced 55 hp. From 1995 finished 1997, the model engine increased to 55 hp and the "high-output" 1.3 liter produced 70 hp.
