A number of interior, exterior and mechanical updates were made for 2004. The V6 engine added slightly more power and is now rated at 265 horsepower and 253 pound-feet of torque. Outside, you'll find a restyled front fascia, new chrome trim, dual exhaust tips, a new wheel design for Touring models, updated headlights and taillights and a rear wing spoiler. The interior now features trendy brushed metal-look trim for the center stack, leather armrests, auto-on/off headlights, new ambient foot lighting and enhanced functionality of the second-row seat for third-row access. Touring models get a new version of the Bose premium audio system and power lumbar support for the driver seat. Finally, safety has been improved on all MDXs with the addition of side curtain airbags and a tire-pressure monitoring system.
