The 2009 Dodge Viper is a two-door two-passenger sports car that comes as either as the SRT10 Convertible or as the SRT10 Coupe. The Dodge Viper offers a lot of power under the hood and comes standard with an 8.4L V10 20-valve engine that is capable of 600 horsepower. This powerful engine comes standard with a six-speed manual transmission with overdrive.
The EPA guide shows that the Dodge Viper SRT10 convertible has a fuel economy rating of 13 miles per gallon in the city and 22 miles per gallon when driving on the highway. This then gives a combined fuel economy rating of 16 miles per gallon. When we look at the Dodge Viper SRT10 coupe, there is the same 8.4L V10 20-valve engine that produces 600 hp and comes paired to a six-speed manual transmission. With the same engine and transmission combination, the coupe achieves the same fuel economy rating as the convertible – 13 miles per gallon in the city and 22 miles per gallon when driving on the highway for a combine of 16 miles per gallon.
