EADS Socata today unveiled the TBM 850, a slightly faster, re-engined version of its TBM 700 turboprop single. The new model will have a maximum cruise speed of 320 knots, 20 knots faster than its predecessor thanks to a higher-power 1,825-shp Pratt & Whitney Canada PT6A-66D engine (derated to 850 shp). The TBM 700 is powered by a 1,583-shp PT6A-64 derated to 700 shp. According to Socata, the two aircraft have the same internal and external dimensions and are nearly identical in weights, with the TBM 850 able to carry an extra 60 pounds of payload with maximum fuel. NBAA IFR range is also similar: the TBM 850 can fly 1,519 nm at long-range cruise speed and 1,365 nm at max cruise speed; the TBM 700's range is 1,565 nm and 1,315 nm, respectively. The TBM 850 is already certified by the EASA, and FAA approval is currently pending. Deliveries of the $2.58 million turboprop single will begin early next year. A typically equipped, RVSM-ready TBM 850 will cost $2.8 million.
