Which Should You Buy: Diamond DA42 or Diamond DA62?

Bottom line: Choose the DA42 Twin Star for efficient twin flying and training — a modern, economical diesel twin with the redundancy of two engines and low fuel burn, ideal for multi-engine training and four-seat touring. Choose the DA62 when you need more room and reach — five to seven seats, more power and longer range, in the same composite, diesel-efficient mould. On safety both are light twins offering engine-out redundancy but, like all light twins, rewarding proficiency in engine-out handling; the DA62 simply carries more. The Twin Star is the efficient trainer-twin; the DA62 is the bigger family twin.

Frequently Asked Questions

What's the difference between the DA42 and DA62?
Size and power. The DA42 Twin Star is a four-seat diesel twin; the DA62 is a larger five-to-seven-seat twin with more power, cabin and range. Both share Diamond's composite, jet-A diesel design.
Are both diesel?
Yes — both use Austro jet-A (diesel) engines, known for low fuel burn and running on widely available jet fuel. That efficiency is a core Diamond selling point.
Is the DA62 just a bigger DA42?
In spirit, yes — it's the larger, more powerful development with more seats and range, but it's a distinct, newer design rather than a simple stretch.
Which is better, Diamond DA42 or Diamond DA62?
It depends on your mission and budget. The DA42 cruises at 170 kts with 1,050 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 DA42: from $601,394. 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 DA42 and Diamond DA62?
Seats: 4 vs 7. Cruise: 170 vs 175 kts. Range: 1050 vs 1100 nm.
Which is cheaper to operate per hour?
DA42: about $150/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?
DA42: 4 seats / 940 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?
DA42: 1,800-hour TBO, overhaul ~$28,000. DA62: 1,800-hour TBO, overhaul ~$30,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
