Performance and Efficiency
VTEC® (Variable Valve Timing & Lift Electronic Control): Delivers a broader, flatter torque curve and smooth power delivery across all RPM ranges for peak power, torque, and fuel efficiency.
BLAST® (Boosted Low Speed Torque): Aggressively advances the ignition curve for rapid acceleration and vastly improved hole shots — gets the hull on plane quicker.
New Friction Reduction Technology: Increases fuel efficiency, extends range, and reduces operating costs.
Lean Burn Control®: Optimizes combustion on a leaner air-to-fuel mixture for superior fuel efficiency and more environmentally responsible operation.
Fully Balanced Engine & Crankshaft: Exceptional performance with minimal vibration. Crankshaft uses the same high-strength alloy as Acura NSX supercar.
Non-Linear Engine Mount: Integrates with 60° V8 design for smooth, low-vibration operation.
Stunning Speed & Acceleration: Delivers exhilarating high-propulsion performance with robust torque and smooth response.
