The 2005 Mitsubishi Eclipse lineup loses the base level RS. A special edition Eclipse is available this year, which Mitsubishi has dubbed the REMIX.  This package adds special interior trim, leather seating, chrome exhaust, 16-inch alloy wheels and a 210-watt Infinity audio system with a six-disc CD changer.

There are three trim levels for the 2005 Eclipse.  The GS is now the entry-level model, priced below the GT and the top-shelf GTS. All Eclipses now come standard with full power accessories, air conditioning, a leather-wrapped steering wheel, cruise control, cup holders, keyless entry, a CD player, a rear spoiler, and alloy wheels.

The GS is the only Eclipse to retain the the 2.4-liter inline four, which delivers 147 horsepower and 158 pound-feet of torque. The GT is powered by a 3.0-liter V6 that produces 200 horsepower and 205 pound-feet of torque. The GTS's V6 makes 210 horsepower. All styles come standard with a five-speed manual transmission, while a four-speed automatic is optional. Fuel economy estimates range from 20/29 for the V6 to 23/31 mpg for the four cylinder.

Consumers and reviewers have expressed disappointment with the lack of standard safety features across the Eclipse lineup. Only the GTS is eligible to receive items like ABS, traction control, and side airbags. The Eclipse did earn high scores in crash tests, however.

Many also commented that the interior could be livened up a bit and that Mitsubishi should reduce the amount of lower-quality materials. Rear quarters are extremely tight, but passengers in front will enjoy wide and well-padded seats.
