Honda borrowed the basic design of the popular MDX from its upscale Acura division, and transformed it into a new midsize SUV. The 2003 Pilot shared its basic chassis and powertrain with the more costly Acura MDX, and used the same V6 engine, five-speed automatic transmission, and all-wheel-drive system. Built on the same wheelbase as the MDX, but a bit shorter overall, the Pilot had different styling and softer suspension tuning. It was also slightly taller and wider. Unlike the seven-passenger MDX, Honda's Pilot could seat eight and had 16-inch wheels instead of 17s. Honda's version had 8.8 cubic feet more cargo space. Models included the basic LX and a pair of upscale versions: EX and leather-upholstered EX-L. All Pilots had antilock four-wheel disc brakes and front side airbags. Rear or curtain side airbags were unavailable. Pilot's AWD system lacked low-range gearing, but a locking rear differential could provide additional traction when needed. Maximum towing capacity was 4500 pounds. The one-piece rear liftgate did not have separate-opening glass. Second- and third-row seats were 60/40 split-folding benches. The EX model added alloy wheels, keyless entry, a power driver's seat, automatic climate control, and upgraded audio with steering-wheel controls. Optional on the EX-L were a navigation system and rear DVD entertainment, although they were not available together. Rivals included the Ford Explorer, Nissan Murano, and Toyota Highlander.
