Premium unleaded gasoline.

Fuel and ignition system ME 9.7 engine management. Integrated sequential multipoint fuel injection and ignition with individual cylinder control of fuel spray, spark timing and antiknock. Electronic throttle. One high-energy ignition coil and spark plug per cylinder. 100,000-mile spark-plug intervals.

Intake system Dual overhead camshafts with continuously variable intake and exhaust timing. Magnesium 2-stage resonance intake manifold increases intake runner length at lower rpm for improved response. Electropneumatic turbulence flaps at start of intake path help increase intake airflow speed at midrange rpm for greater air-fuel mixture swirling and stronger, more complete combustion.

Manual Transmission Standard fully synchronized 6-speed with direct-action short-throw shifter and clutch-starter interlock.

Automatic Transmission Optional 7-speed automatic. Electronically controlled shifting. Driver-adaptive programming adjusts shift points to the driver's current driving style. Touch Shift allows driver to manually downshift and allow upshifts by nudging the shift lever left or right from the Drive position. Shift into Optimum Gear programming allows one-touch selection of the best gear for maximum acceleration or engine braking by holding the shift lever to the left of Drive for one second. Driver-selectable Comfort mode starts vehicle moving in 2nd gear or a second Reverse gear, and upshifts at lower rpm, to help improve control on slippery surfaces. Instrument-cluster readout of selected gear range and Standard/Comfort mode.
