Worth knowing about the 2023 C-Class

  • Torque. Tighten lug nuts to 111 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
  • Wheels. The C-Class uses wheel bolts rather than lug nuts; tighten them in a diagonal pattern, first to 59 ft-lb and then to the final figure.
  • Garage fit. Allow 15.6 ft of length and 6.7 ft of width with the mirrors out.
  • Dimensions. 4MATIC models have a 37.57-ft turning circle.
  • Octane. Premium (91 octane) is required, not recommended; the manual says so.
  • Fuel. The manual calls for premium 91 AKI and allows regular 87 AKI only as a temporary measure.
