The 2010 Pontiac G5 GT makes sense for buyers seeking a small, front-wheel-drive gasoline car with automatic shifting. Its strongest official efficiency figure is 32 MPG on the highway, while urban use is rated at 23 MPG. EPA estimates put yearly fuel cost at $2,600, and tailpipe emissions at 341.81 grams per mile. Consider this model when those running figures and its subcompact body align with your daily routes.

What it is

The G5 GT is a 2010 Pontiac subcompact car. It uses front-wheel drive, a 2.2-liter four-cylinder engine, and a four-speed automatic transmission.

Gasoline is its fuel. The defining EPA figure is 26 MPG combined, with separate ratings of 23 MPG city and 32 MPG highway.

The numbers

The 23 MPG city rating fits stop-and-go driving, while 32 MPG highway applies to steadier road travel. The combined figure blends those two ratings into 26 MPG.

Its EPA tailpipe output is 341.81 grams of carbon dioxide per mile.

What it costs to run

EPA lists annual fuel cost at $2,600. That figure is tied to the G5 GT's official fuel-economy ratings, so your result will depend on how much you drive and how much of it is in town or on the highway.

How it compares

Within this car's own EPA ratings, highway mileage is 9 MPG higher than city mileage. Drivers doing more highway travel should use the 32 MPG number when judging fuel use; city-heavy trips are represented by 23 MPG.

The 26 MPG combined rating gives one figure for mixed driving; the listed base model is the G5.

Who it suits

This car suits a driver who wants a small gasoline car with an automatic transmission and front-wheel drive. It also fits someone whose driving includes enough highway travel to make use of the 32 MPG rating.

Trade-offs

The G5 GT's 32 MPG highway rating is notably higher than its 23 MPG city rating, so frequent urban trips will not match its combined figure. Its gasoline powertrain also carries an EPA annual fuel cost of $2,600 and tailpipe emissions of 341.81 grams per mile.

Verdict

Choose the 2010 Pontiac G5 GT if a compact footprint, front-wheel drive, and a four-speed automatic match your needs. Its official fuel figures favor open-road travel, but city driving lowers the result to 23 MPG. The EPA cost estimate gives this car a clear yearly fuel budget, while the emissions figure shows the output tied to its gasoline use. Review your own city-versus-highway split before deciding whether its 26 MPG combined rating fits your routine.
