2004 Mitsubishi Diamante Overview

By Cars.com Editors
Vehicle Overview
What Mitsubishi terms a “resculpted” Diamante went on sale in November 2003. The styling features of the face-lifted near-luxury sedan include a new front fascia with a split upper grille, projector-style triangulated headlights and a mesh lower air intake. Unlike previous Diamante models, the bumpers are more integrated and the rear end is less angular. The front fenders display a more dominant look.

The interior features a new instrument panel and console. Premium cloth upholstery in the entry-level ES model has a more upscale ambiance, according to Mitsubishi. Both the luxury LS and sporty VR-X contain a 270-watt Infinity premium audio system. A Sportronic automatic transmission features a manual gear change provision; it is standard in the LS and VR-X. The VR-X also gets unique sport suspension tuning, traction control and a low-restriction exhaust system.

Built in Australia, the front-wheel-drive Diamante uses a 3.5-liter V-6 engine. Antilock brakes are standard. The VR-X trim level joined the lineup of Mitsubishi’s near-luxury sedan in 2002. With a more aggressive exhaust sound and an engine that delivers 5 horsepower more than the 3.5-liter V-6 in other Diamantes, the VR-X is said to add sporty appeal to the sedan line. For 2003, the VR-X got new European sport-style bucket seats, colored-taillight surrounds, sport seat fabric, and aggressive side-skirt air dams and wheel lip moldings.

The Diamante debuted in its current form in the 1997 model year as a lower-priced alternative to such models as the Infiniti I35 and Lexus ES 300


Exterior
Mounted on a 107.2-inch wheelbase and measuring 196 inches long overall, the Diamante is almost 6 inches longer than Mitsubishi’s newly redesigned Galant sedan. The VR-X features unique headlights and taillights, a deck lid spoiler and color-keyed bodyside trim. Fog lamps are installed on the LS and VR-X versions. Alloy wheels on each model hold 16-inch tires, and a sunroof is standard.

Interior
Cloth upholstery is used in the base ES sedan, while the more costly LS gets leather-faced seating surfaces. The front bucket seats in the ES have manual adjustments, and the LS’s buckets are power adjustable. All Diamantes seat five people.

Standard ES equipment includes automatic air conditioning, a six-speaker stereo with a CD player, cruise control, remote keyless entry, and power windows, locks and mirrors. The LS sedan adds steering-wheel audio controls, a 270-watt Infinity premium sound system, heated seats and mirrors, and power front seats with a memory feature. Sport-style bucket seats, a white-faced gauge panel and platinum-finished accents go into the VR-X. The sedan’s trunk holds 14.2 cubic feet of cargo.


Under the Hood
A 205-hp, 3.5-liter V-6 engine is installed in the ES and LS versions. The V-6 in the VR-X produces 210 hp. Both engines team with a four-speed-automatic transmission. In LS and VR-X models, the automatic incorporates a Sportronic mode for manually selected gear changes.

Safety
All-disc antilock brakes are standard, but side-impact airbags are not available. Traction control is standard on the VR-X and optional on the LS.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
