DETROIT The Chrysler group will extend its popular Hemi brand with a second, more powerful engine.
The 6.1-liter Hemi V-8 will arrive in the 2005 Chrysler 300 SRT-8, which will reach showrooms in the spring, the company said in a release last week.
The engine is expected to power additional vehicles, including a 2005 Dodge Magnum SRT-8 and the 2006 Dodge Charger, according to sources.
SRT is the companys high-performance brand. Typically, only several thousand units of an SRT model are built.
The new Hemi will generate 425 hp in the Chrysler 300 SRT-8. The Chrysler 300C equipped with the 5.7-liter Hemi generates 340 hp. Chrysler will keep the 5.7-liter Hemi for high-volume production.
Chrysler has not yet priced the SRT-8. The Chrysler 300C carries a $33,495 price tag. For comparison, the base Chrysler Crossfire coupe has a $29,920 sticker. The Crossfire SRT-6 coupe is $45,695. All prices include destination charges.
To develop the high-output engine, Chrysler increased the displacement and compression ratio. It also redesigned the cylinder head intake and exhaust systems for increased airflow.
Chrysler revived the Hemi name in 2002 for a new V-8 engine. The name refers to the hemispherically shaped top of the combustion chamber.
The popularity of the modern Hemi has surprised even Chrysler executives. For example, installation rates are 47 percent on the Chrysler 300 and Dodge Ram, 56 percent on the Dodge Durango and 46 percent on the Dodge Magnum, the company says.
The Chrysler groups performance unit has developed six SRT vehicles: the Dodge Viper SRT-10, Dodge SRT-4, Dodge Ram SRT-10, Dodge Ram SRT-10 Quad Cab and the Chrysler Crossfire SRT-6 coupe and roadster.
