The Tupolev Design Bureau introduced the Tu-334 in early 1989 as an eventual propfan-powered airliner to potentially enter service for Aeroflot in 1995. However, it would have an interim turbofan-powered version that would begin airline service around 1991–1992. Consuming about 20 percent less fuel than the best Soviet turbofan, the propfan engine would be a then-unnamed geared powerplant from the Lotarev engine design bureau. The engine would have a thrust specific fuel consumption (TSFC) of 13 g/(kN⋅s) (0.46 lb/(lbf⋅h)), resulting in a per-passenger aircraft fuel consumption rate of 13 grams per kilometre (0.74 ounces per mile). The turbofan-powered version of the Tu-334 would use Lotarev D-436T engines with a TSFC of 18 g/(kN⋅s) (0.62 lb/(lbf⋅h)) and a bypass ratio of 6.5, and it would consume 20 g/km (1.1 oz/mi) per passenger. The propfan Tu-334 would seat 104-137 passengers, compared with 86-102 passengers for the shorter, turbofan Tu-334.

Tu-334-100
Basic version,
with accommodation for 72 passengers in mixed-class configuration (12 first-class and 60 tourist-class) or 102 passengers in high-density layout. Two 73.6 kN (16,500 lbf) Progress D-436T1 turbofans.
As late as 2008, Tupolev reported that a total of about 100 airlines had expressed an interest in placing orders for Tu-334s;
In 2009, with the project years behind the projected schedule and only two examples built and flying ten years after the first flight, the Tu-334 came under review during the rationalisation of the Russian aircraft companies.
