Isuzu's crossover SUV gains 20 hp for 2004. Axiom is basically a midsize Rodeo SUV with a sleeker body. It comes in S and uplevel XS models. Both have a 3.5-liter V6, now with revisions that boost it to 250 hp. A 4-speed automatic is the sole transmission. Axioms are available with rear-wheel drive or Isuzu's Torque On Demand 4WD that can be left engaged on dry pavement and has low-range gearing. Axiom shares Rodeo's wheelbase but is 6 inches longer overall. ABS is standard. Side airbags are unavailable. Both models have 17-inch alloy wheels, and 4WD versions have rear disc brakes instead of drums. Isuzu's Intelligent Suspension Control, which automatically varies shock-absorber firmness, is standard on all but the 2WD S. XS models come with a sunroof, heated front seats, and leather upholstery.
