Rear passengers were slightly more cramped, with headroom of 37.5 inches and legroom of 36.6 inches. Total cargo space for the Diamante was 14.2 cubic feet.

Mitsubishi Diamante Trim Levels

The Mitsubishi Diamante was originally available in two trim levels – ES and LS. A mid-range, performance-oriented VR-X trim was introduced for the 2002 model year. The base ES model came standard with features such as air conditioning, automatic climate control, cruise control, power steering, height-adjustable driver's seat, full power accessories, remote keyless entry, stereo system with CD player, power sunroof and automatic-off headlights.

The Mitsubishi Diamante VR-X added an 8-way power driver's seat, leather-wrapped steering wheel, upgraded stereo system, heated power mirrors and a rear spoiler. The top-tier LS rounded out the lineup with leather seats, 10-way power driver's seat with memory system, 8-way power passenger's seat and steering wheel radio controls.

Mitsubishi Diamante Performance

In America, the Mitsubishi Diamante was only available with one engine option – a 3.5-liter OHC V6 engine that delivered 205 horsepower and 231 lb-ft. of torque. The VR-X trim featured a tuned version of the same powertrain that delivered 210 horsepower. All models came standard with a 4-speed automatic transmission. The VR-X and LS boasted a manual shift capability.

Other notable performance features available on the Diamante included a sport suspension and traction control. EPA-estimated fuel efficiency for the 2004 Mitsubishi Diamante was 18 mpg in the city and 25 mpg on the highway.

Mitsubishi Diamante Safety

Standard safety features for the Mitsubishi Diamante included dual front airbags, 4-wheel antilock brakes and an emergency trunk release. The vehicle was not tested for safety by either the NHTSA or IIHS.

Used Mitsubishi Diamante

The Mitsubishi Diamante never quite reached the luxury status that Mitsubishi had intended. Class leaders such as Lexus and Acura continue to outshine the Diamante in the used car market. This low demand may make the Diamante a great bargain option for individuals shopping for a used luxury automobile.
