Diamond DA40 vs Diamond DA62

The Diamond DA40 Star and Diamond DA62 are both modern composite Diamonds, but they answer very different questions. The DA40 is a four-seat single — the airplane many owners learn in and never quite outgrow; the DA62 is a five-to-seven-seat twin with two engines and far more carrying capability. Current prices and how many of each are on the market are below.

Which Should You Buy: Diamond DA40 or Diamond DA62?

Bottom line: Pick the DA40 for efficient, low-cost single-engine flying — a forgiving, economical four-seater that's ideal for training, hour-building and short trips. Move to the DA62 when you need real seats, longer legs and twin-engine redundancy, and can carry the cost of a larger airframe and two engines. Safety is where this comparison gets interesting: the DA40 has one of the lowest fatal-accident rates in general aviation, so its case is a proven single-engine record, while the DA62 answers safety differently — a second engine and the dispatch margin that comes with it. Single-engine economy with a stellar record, or twin redundancy with the seats to match — that's the real fork.

Pick the DA40 if…

  • Budget matters — from $184,562 vs $1,042,000, you save ~$857,438.
  • Lower operating cost — ~$120/hr vs $160/hr.
  • More inventory — 89 listings vs 68.

Pick the DA62 if…

  • More seats — 7 vs 4.
  • Faster cruise — 175 kts vs 135 kts.
  • Longer range — 1100 nm vs 635 nm.
  • Newer design — production from 2015 vs 2000.

Frequently Asked Questions

Is the DA62 just a twin DA40?
No — the DA62 is a larger, heavier five-to-seven-seat twin with two engines, more cabin and more range. The DA40 is a four-seat single. They share Diamond's composite construction but serve different missions and budgets.
Which is more economical?
The DA40, clearly — one diesel engine means lower fuel burn, lower maintenance and a lower purchase price. The DA62 adds seats, range and engine redundancy, and costs accordingly.
Are Diamond aircraft diesel?
Most are — Diamond's Austro jet-A diesels are common on both, though some DA40s use a Lycoming avgas engine. Always confirm the engine type and its remaining hours on the specific aircraft you're looking at.
Which is better, Diamond DA40 or Diamond DA62?
It depends on your mission and budget. The DA40 cruises at 135 kts with 635 nm range. The DA62 cruises at 175 kts with 1,100 nm range. Review the specs table above to find which fits your flying profile.
How do prices compare?
Diamond DA40: from $382,026. Diamond DA62: from $1,299,000. Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Diamond DA40 and Diamond DA62?
Seats: 4 vs 7. Cruise: 135 vs 175 kts. Range: 635 vs 1100 nm.
Which is cheaper to operate per hour?
DA40: about $120/hr variable cost. DA62: about $160/hr variable cost. Variable cost includes fuel, reserves and overhaul accruals. Annual fixed costs (hangar, insurance, annual inspection) add to the total.
Which has more seats and useful load?
DA40: 4 seats / 780 lb useful load. DA62: 7 seats / 1,300 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?
DA40: 2,000-hour TBO, overhaul ~$25,000. DA62: 1,800-hour TBO, overhaul ~$30,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
