[2] Shortly after launch, the TBM 700 was a market success, which led to the production of multiple variants and improved models, often incorporating more powerful engines and new avionics.

From the onset, key performance criteria were established for the design, demanding a high level of reliability while also being capable of an unequalled speed/altitude combination amongst the TBM 700 other single-engined peers.

[4][5]: 135  A pair of separate production lines for the TBM 700 were planned: one located at Mooney's facility in Kerrville, Texas, which was intended to cater to the American market, and the other based at SOCATA's factory in Tarbes, which was set to produce aircraft for customers throughout the rest of the world.

Early feedback received from operators and pilots was typically positive regarding the capabilities of the new aircraft, with the speed and generous power margins, amongst other attributes, specially noted.

The modifications made upon this model included the addition of a baggage compartment aft of the rear pressure bulkhead, the strengthening of the wing and landing gear, and seat crashworthiness certification for up to 20 G to accommodate for an elevated stall speed at higher weights.

Around the same time, SOCATA decided to re-design the interior of the aircraft, including the fittings and finish, along with the adoption of a new integrated environmental control system, to improve passenger comfort levels.

[7] The adoption of a sharp strake, located forward and beneath the leading edge of the left wing, also provides for improved stall characteristics over the earlier TBM variants.

According to aircraft publication Aviation Week, various subtle exterior changes were made for drag reduction purposes, including the addition of inner main landing gear doors, the re-contouring of the tail cone and of the engine nacelle.

In combination with a more efficient air inlet, which boosted the available torque and ram recovery, and reshaped exhaust stacks, which increased thrust output, makes the plane faster.

[8] At the June 2018 Eurosatory, an ISR configuration with underwing hardpoints and electrical connections for sensors and aerial photography was offered for defense, security, medical evacuation and transport missions.

Competing with heavier aircraft and MALE UAVs, it benefits from its short field performance and speed, offers six hours of surveillance and can be reconfigured for other duties.

It was validated with a 110-pound (50-kg) camera and a multi-sensor optronics retractable turret, SAR/ground MTI radar, communication interception system, and secure transmission with a quick-change console for tactical situation monitoring.

[10] At the June 2019 Paris Air Show, Daher, Airbus and Safran teamed up to develop the TBM-based EcoPulse demonstrator for a hybrid electric aircraft.

The aircraft's existing engine will be supplemented by six Safran electric motors on the wings fed by a 100 kW (130 hp) APU or batteries.

[13] Airbus Defence and Space is developing the 230 by 75 by 20 cm (91 by 30 by 8 in) lithium-ion battery to be mounted on the fuselage underside, weighting 350 kg (770 lb) for a power of 350 kW (470 hp).

The wing features a very effective Fowler flap, comprising 80 per cent of the trailing edge's span, for the purpose of lowering the aircraft's stall speed.

[2] The ice protection system is as automated as possible, the windshield being electrically heated, the air inlet being kept warm by engine exhaust and the de-ice boots automatically cycling once activated.

The ETM, which is connected to the aircraft's air data computer, also provides information to enable easy power management by the pilot.

The G1000 also has upgraded displays, including an ISA temperature deviation indication, integrated weather radar and MFD map, and automatic landing field elevation inputs to the pressurization controller.

The seats are certified for their crashworthiness for up to 20 G. From the TBM 850 onwards, a combined air conditioner/environmental control system was integrated into the cabin, being simpler and requiring less adjustment than the prior arrangement.

[8] Later built models are equipped with winglets, which were developed by SOCATA primarily to reduce drag when flown at high angles of attack, such as during takeoffs, as well as to enhance the aircraft's aesthetics.

According to SOCATA, Hartzell's selection over a similar advanced counterpart from MT-Propeller was made due to the former raising the cruise speed by around 3 to 5 kn (5.5 to 9 km/h).
