Class 1 Competition



Based off of the quad cam four valve (QC4v) engine platform, the 850 h.p. Class 1 Competition pumps out 850 lb-ft of torque from 2500 to 5250 rpm and delivers 850 horsepower at its 6,350 rpm red line. All of this power and torque comes from 89 posted octane (R+M)/2, (95 RON, global) pump gas.

  • Durable: The 32 valve quad cam valve train offers extreme durability at high horsepower and engine speeds so you can be confident in knowing that the engine can handle anything you can.
  • Drivability: Mercury Digital Throttle & Shift (DTS) technology provides instant throttle response and luxury-car-like drivability
  • Robust: World champion M6 sterndrive to handle to the 860's high torque
  • The Class 1’s fuel calibration is unique for its application, but it’s function is very similar. It shifts just as sweetly and throttles just as effortlessly as it’s QC4v siblings. It features an integrated, water-cooled twin turbo exhaust system. The digitally modulated boost control is employed to handle the engines’ massive, flat torque line. And, as with all QC4v engines, The Class 1 is drive-by- wire and features an electronically shifted transmission.
  • The Class 1 is available with the dry-sump NXT6 drive with gear ratios from 1.15.1 to 1.42:1 or as an engine only.
