Worth knowing about the 2026 CX-70

  • LED lighting. The low beam, high beam, daytime running, front turn signal, rear turn signal, brake light, tail light, reverse light, license plate, dome / map light are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
  • Spare. This vehicle carries a compact (temporary) spare, size T155/90D18. Search Amazon for spare tires →
  • Tire chains. The manual permits tire chains or cables, within limits on which tires and which wheels. Those limits are in the next note; read them before you fit anything. Search Amazon for tire chains →
  • Tires. The manual allows chains on the rear tires only and forbids them on the front tires; the temporary spare is fitted on some models only and the others carry an emergency flat tire repair kit.
  • Torque. Tighten lug nuts to 94 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.
  • Dimensions. The figures above are for the 3.3 Turbo (MHEV); other body configurations differ in length, wheelbase and weight.
  • Dimensions. Overall length is 201.6 inches with the license plate holder.
  • Fuel. The 3.3 Turbo S (high-power) engine calls for 91 octane premium; 87 can be used with slightly reduced output.
