The 1998 Mitsubishi Diamante is equipped with a 3.5L, SOHC 24-valve V6 that produces 210 horsepower. The four-speed automatic learns the drivers typical driving habits and adjusts shift strategies accordingly, resulting in smoother shifting, more responsiveness and improved fuel economy. The Diamante has a low drag coefficient of 0.28. Standard equipment includes a 4-wheel anti-lock braking system and a remote keyless entry system. The new solar tinted glass helps block out ultraviolet light, keeping the interior cooler while reducing sun damage to interior materials. The Diamante competes in a class with premium sedans such as the Acura TL, Lexus ES 300, Mazda Millenia and Mercedes-Benz C-Class.
