2001 Mitsubishi Diamante Full Review
Date Published: 7/31/08
2001 Mitsubishi Diamante Review
The flagship of Mitsubishi's U.S. line offers V6 ES and luxury LS sedans with 4-speed automatic transmission, ABS, and 4-wheel disc brakes. Diamante LS adds leather upholstery, power sunroof, and 16-inch alloy wheels versus ES's 15-inch steel rims. Both 2001 models get rear child-seat anchors, and LS adds standard foglamps, which had been part of an All-Weather package. That option is still available for LS and includes heated mirrors and front seats, plus traction control. Side airbags are not available.
Competition
This hotly contested segment has a clear benchmark; it is the Acura TL (and its 2-door cousin Acura CL). The TL succeeds in blending comfort, style, luxury, and sport into an efficient package at an affordable price. If you are leaning more toward the luxury scale, the Lexus ES 300 might be a more practical purchase.

We also recommend the sporty and Euro-flavored Audi A6, the comfortable Buick Park Avenue, the affordable and fast Infiniti I30.
News
Diamante's annual U.S. sales haven't crested the 10,000 mark in several years, and 2000 was no exception. In fact, the model took a hit, easing 7 percent from '99 to just over 9200 units.

The 2002 Diamante turned up at last April's New York Auto Show, though sales don't begin until this fall. Full details weren't available for this report, but the main news is updated styling, with new-look front and rear ends--including a grille bisected by an eagle-like beak--plus a flatter rear deck. Other than this and maybe a few new features, the '02 is familiar fare. However, Mitsubishi will try to give Diamante some "sports sedan" cache in February 2002 with a new VRX version featuring rear spoiler, lower-body "aero" skirts, handling-oriented suspension tuning, and more horsepower (as yet unspecified) than regular models possess.

Mitsubishi is now controlled by DaimlerChrysler, which is scrambling to cut losses at its Japanese affiliate as well as at Chrysler Group. This inevitably means future models from both companies designed around shared platforms and components, hopefully without being too obvious about it. What this means for Diamante is unclear. Mitsubishi's larger cars have never sold well in the U.S., and with Diamante sales still at the bottom of the class, the model could well be dropped after its current "design cycle". That was supposed to run out after 2002, but Mitsubishi has apparently torn up most of its previous product plans since DC took over, and late word has the next fully redesigned Diamante postponed until at least model-year 2006--if it appears at all. Assuming it does, this would be a stretched version of the midsize Galant and built alongside it at Mitsubishi's Illinois plant in the way the full-size Avalon relates to Camry at Toyota. Galant itself is reportedly being redesigned for 2005 on a new platform to be shared with next-generation Chrysler Sebring/Dodge Stratus models. Lately, though, DC, Mitsubishi, and even industry moles have been silent on Diamante, so it seems right now that a flagship Mitsubishi sedan has no more than a 50/50 chance of making it to mid-decade.

Ride
Consumer Guide® Road Test Ratings
Acceleration

LS Class Average
6 6.1

Our test LS did 0-60 mph in a competitive 8.1 sec. Traction control checks unwanted wheelspin in hard takeoffs, but should be a freestanding option for both models.
Fuel Economy

LS Class Average
5 4.7

We averaged 19.7 mpg with lots of highway driving. Expect closer to 17 in town.
Ride Quality

LS Class Average
7 6.4

Most bumps are easily absorbed, but soft damping allows mild float to occur over fast humpbacks.
Steering/Handling/Braking

LS Class Average
5 6.3

Soft damping allows more cornering lean than desirable, but Diamante is competent, safe, predictable, though less nimble than rivals like Acura TL.
Quietness

LS Class Average
6 6.7

This V6 isn't the smoothest around, but it's pretty relaxed and hardly vibratory. Wind and road noise low, but some tire thrum is audible on pebbled pavement.
Controls

LS Class Average
6 6.1

Conventional if busy design and layout. Stereo buttons are too small.
Room/Comfort/Driver Seating (front)

LS Class Average
6 7

Good but not grand. LS's sunroof leaves marginal 6-footer head room. ES provides more clearance. Good basic driving stance with sufficient adjustments. Visibility marred by a mild over-the-shoulder blind spot.
Room/Comfort (rear)

LS Class Average
5 5.1

Too narrow for three adults to be comfortable, and leg room can be tight with the front seats pushed very far back.
Cargo Room

LS Class Average
3 4

Trunk is roomy and easy to load, but not the largest in its class, and the lid hinges cut into the available space.
Value within Class

LS Class Average
2 4.7

Diamante is a competent but rather dull car that's well equipped and attractively priced, but it's bettered in most ways by most rivals, especially the value-packed Acura TL. It also lags in prestige and therefore resale values.

Pricing Key: Retail prices listed with each report are set by the vehicle's manufacturer. These figures appear on each car's federally mandated window sticker. Most price lists also include dealer-invoice prices. Dealer-invoice prices are what the dealer pays the manufacturer for the car and its factory-installed options. The destination charge is not included in the suggested-retail or dealer-invoice price and must be added to the cost of the vehicle. Car companies change prices frequently throughout the year. If the prices published do not match those on the vehicle's window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

NHTSA Crash-Test Results
Test Mitsubishi Diamante 4-door sedan
The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
