Which Should You Buy: Cessna 172 or Diamond DA40?

Bottom line: Choose the SR20 for the Cirrus ecosystem — a glass cockpit and the CAPS parachute, and a clean path up to the SR22 and beyond. Choose the 172 Skyhawk for the proven, economical default with unmatched support. Choose the DA40 Star for composite efficiency and one of GA's best safety records. On safety the SR20 adds a whole-airframe parachute, the DA40 brings an outstanding accident record, and the 172 a long benign history — three strong, different cases. Parachute-and-ecosystem, proven standard, or composite record.

Pick the 172 if…

  • Budget matters — from $61,563 vs $184,562, you save ~$122,999.

Frequently Asked Questions

What's the difference between the SR20, 172 and DA40?
The SR20 is a composite Cirrus with a parachute; the 172 the classic high-wing standard; the DA40 a modern composite. All are four-seat trainers differing in materials, features and feel.
Which has a parachute?
The SR20 — the Cirrus CAPS whole-airframe parachute is standard. The 172 and DA40 rely on conventional engine-out handling and strong safety records.
Which is best to train in?
All are excellent — the 172 for ubiquity and cost, the SR20 for glass and the Cirrus path, the DA40 for efficiency and record. School fleet and preference usually decide.
Which is better, Cessna 172 or Diamond DA40?
It depends on your mission and budget. The 172 cruises at 118 kts with 518 nm range. The DA40 cruises at 135 kts with 635 nm range. Review the specs table above to find which fits your flying profile.
How do prices compare?
Cessna 172: from $119,900. Diamond DA40: from $382,026. Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Cessna 172 and Diamond DA40?
172 engine: LYCOMING (180 hp). Cruise: 118 vs 135 kts. Range: 518 vs 635 nm.
Which is cheaper to operate per hour?

Which has more seats and useful load?
172: 4 seats / 878 lb useful load. DA40: 4 seats / 780 lb useful load. Useful load = max gross weight minus empty weight; it determines how much fuel plus payload you can carry.
How does maintenance compare — TBO and overhaul cost?
172: 1,400-hour TBO, overhaul ~$30,000. DA40: 2,000-hour TBO, overhaul ~$25,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
