December 10, 2004 - In the spring of 2005, Chrysler Group will up the ante and unleash an all-new, beefed-up 6.1-liter 425-horsepower HEMI V-8 engine in the new 2005 Chrysler 300C SRT8. Preliminary performance targets for Chrysler 300C SRT8 are 0-60 mph in the low five-second range and a quarter-mile time in the high 13-second range.

The 425-horsepower, naturally aspirated 6.1-liter HEMI will be the highest specific-output V-8 engine ever offered by the Chrysler Group. Its 69.8 horsepower-per-liter rating exceeds even that of the legendary 1966 "Street HEMI." Torque is rated at 420 lb-ft.

Chrysler Group builds HEMI engines at its Saltillo (Mexico) Engine Plant. Production for the 6.1-liter HEMI begins in early 2005.
