With the DA40, Diamond did the right thing and asked Katana users what engine they would like to see in the new DA40. Overwhelmingly, the response was the fuel injected, parallel-valve, 180-hp Lycoming IO-360 like that installed in the new Cessna 172SP and a fuel-injected version of what powers the New Piper Archer III. But instead of a fixed-pitch propeller, the Diamond Star will have a three-blade, constant-speed prop. Like the 172SP, the DA40 is likely to find itself used as a trainer much of the time, which lends itself well to the durable Lycoming IO-360. When used for personal trips or for cross-country training flights, the engine will pull the airplane along fast enough so as not to produce too many yawns or too much time on the Hobbs meter. Diamond expects production DA40s to zip along at 147 knots at 75-percent power. At that power setting, the Lycoming will consume about 10 gallons per hour, which produces good fuel economy for a fixed-gear, four-place trainer.
