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.
