The VTM-4® electronic control unit (ECU) constantly monitors speed and road conditions. When cruising or braking, the Pilot operates in front-wheel-drive only for maximum fuel efficiency. When accelerating, however, the VTM-4® ECU detects wheelspin before it happens. The ECU then calculates the best power split between the front and rear axles and engages 4-wheel drive.
Power is drawn directly from the transmission through a drive shaft that connects to the rear differential. Inside the rear differential are special electronically controlled clutches that supply power to each rear axle.
The VTM-4® electronic control unit, or ECU, constantly monitors vehicle speed and road conditions. When cruising or braking, the Pilot operates in front-wheel-drive only for maximum fuel efficiency. When accelerating, however, the VTM-4® ECU detects wheelspin before it happens, through its sensor data. The ECU then instantly calculates the best power split between the front and rear axles, and engages 4-wheel drive by electronically locking the rear clutches.
A 5-speed automatic transmission features Grade Logic Control. The transmission uses the engine's broad torque curve for class-leading acceleration, optimal fuel economy and smooth-shifting characteristics.
All models are equipped with 16-inch wheels. Styled steel wheels are standard on the LX. Alloy wheels are standard on EX models. All-Season P235/70 R16 104S tires are standard on all models.
The 240-horsepower, 3.5-liter, VTEC® V-6 engine provides plenty of torque across a wide rpm range. The VTEC® valve train adjusts the timing, duration and lift of the intake valves according to engine speed. Additionally, the engine's induction, intake and exhaust systems have been optimized to deliver optimum airflow at all speeds.
The engine burns so lean that the Pilot is rated as an Ultra-Low-Emission Vehicle (ULEV) in states with California emissions standards and as a Low-Emission Vehicle (LEV) under federal standards.
Honda's Multi-Point Programmed Fuel Injection system (PGM-FI) provides responsive, economical and low-emission performance. A powertrain control module (PCM) receives and processes data from a network of sensors. The PCM instantly calculates the engine's fuel requirements, then activates each fuel injector at precisely the right moment in the combustion cycle.
Honda's VTEC® engine enhances the vehicle's broad torque characteristics and reduces exhaust emissions. Ordinary engines have one mode of operation for the valvetrain at all engine speeds. VTEC® offers two distinct modes for the intake valves for improved response throughout the rpm range.
