The aircraft is similar to the popular Cessna 172 but has higher gross weight and a more powerful engine with a geared reduction drive.

While it incorporates airframe changes to accommodate an increased gross weight, the 175 is similar in appearance to the 172 of the same vintage.

The main design change was the introduction of a stepped firewall in the 175, allowing the use of a longer cowl with larger air intakes, increasing airflow for improved engine cooling.

Cessna also fitted the 175's stepped firewall and enlarged, relocated instrument panel to the 172 starting with the 172B model.

[2] Although externally near-identical to the 172 with most parts aft of the firewall being interchangeable, the 175 was built to a different type certificate.

[2][3] The P172D and R172 series (including the T-41B/C/D Mescalero) share the 175 type certificate, along with the 172RG, the retractable landing gear version of the 172.

[2][5] Provisions in the original POH may have contributed to pilot confusion and improper engine operation, as the POH lists cruise speed and fuel burn down to 2400 RPM or 36% power, creating the misleading impression that sustained operation at this RPM setting is safe.
