As of October 2007, the current production version is the ''ATR 72-600'' series. On 2 October 2007, ATR CEO Stéphane Mayer announced the launch of the -600 series aircraft; the ATR 42-600 and ATR 72-600 featured various improvements to increase efficiency, dispatch reliability, lower fuel burn, and operating costs. While broadly similar to the earlier -500 model, differences include adopting improved PW127M engines, a new [[glass cockpit]], and various other minor improvements.<ref>{{cite web |url=http://www.janes.com/articles/Janes-All-the-Worlds-Aircraft/ATR-42-International.html |title=Defense & Security Intelligence & Analysis: IHS Jane's&nbsp;— IHS | access-date=26 December 2014}}</ref>

Since 2008, ATR has been a participant in the European [[Clean Sky]] Joint Technology Initiative. On 8 July 2015, an ATR 72-600 'green' technology demonstrator performed its first flight; the demonstrator was used for testing new [[composite material|composite]] materials for [[Thermal insulation|insulation]], [[air conditioning]] systems, electrical distribution systems, and energy dispersal modifications to evaluate their effect on the aircraft's overall efficiency as a contribution to the Clean Sky initiative.<ref>Polek, Gregory.

During March 2016, a second round of flight trials dedicated the testing of all-electric systems architecture using the demonstrator was completed; analysis is set to continue.<ref>Dubois, Thierry.

As a consequence of strong demand for the -600 series, ATR decided to invest in the establishment of a second, more modern final assembly line and acquisition of more hangar space at its Toulouse site, along with a new large completion and delivery area; overall, the manufacturing operation expanded to four times the footprint that it had in 2005.<ref name="ain nov 2015" /> Speaking in October 2015, ATR CEO Patrick de Castelbajac stated that the firm was set to produce in excess of 90 aircraft that year, and that the new manufacturing facilities could support a production rate of up to 120 per year. At the time, the company had a backlog of orders for 300 aircraft, sufficient for three years of production.<ref name="ain nov 2015" /> During 2017, a new in-house financing and leasing division was established by ATR in order to offer customers a greater degree of support and expand the company's range of services.<ref name="lease freight ain" />

In December 2015, the EASA approved a new high-density seating layout, raising the maximum capacity from 74 to 78 seats.<ref name="ainonline.com">Polek, Gregory.

Considerable emphasis has been placed upon the continuous development of ATR's aircraft models.<ref name="lease freight ain" /> Speaking at the [[Farnborough Airshow]] in July 2016, the CEO of ATR Patrick de Castelbajac stated that the company was currently examining the possibility of replacing the current [[Pratt & Whitney Canada PW127]] engine with either a new offer from P&WC, or a [[General Electric GE38|GE38]] derivative from [[GE Aviation]].<ref name="reengine 2016" /> Although expressing satisfaction with the PW127 engine and its supplier, Castelbajac noted the design's age and the need to remain competitive with the latest [[regional jet]]s. To be a worthwhile exercise, any re-engine exercise would require a 15 per cent improvement in fuel-burn and 20-25 per cent reduction of direct maintenance costs. Additionally, Castelbajac sees the potential re-engine as a "bridge" to the eventual development of a larger 100-seat aircraft.<ref name="reengine 2016">{{cite web |url= https://www.flightglobal.com/news/articles/farnborough-re-engining-atr-could-be-bridge-to-100-427326/ |title= Re-engining ATR could be bridge to 100-seater – CEO |work= Flight global |date= 12 July 2016 |access-date= 12 July 2016 |archive-url= https://web.archive.org/web/20160713163514/https://www.flightglobal.com/news/articles/farnborough-re-engining-atr-could-be-bridge-to-100-427326/ |archive-date= 13 July 2016 |url-status= live }}</ref>

During the mid-2010s, reports emerged that the development of a further stretched 90-seat ATR model was under consideration as well; allegedly, shareholder Airbus was relatively unenthusiastic on proceeding with such a development, while Airbus CEO Fabrice Brégier favoured a focus on resolving manufacturing issues.<ref name="ain nov 2015" /><ref name="chin ain 2014" /> However, in January 2018, ATR's parent company Leonardo announced that the 100-seat program has been formally brought to a close.<ref>{{Cite news|url=https://www.flightglobal.com/news/articles/atr-parent-leonardo-rules-out-100-seat-turboprop-445340/|title=ATR parent Leonardo rules out 100-seat turboprop|date=2018-01-30|work=Flightglobal.com|access-date=2018-06-07|language=en-GB|archive-url=https://web.archive.org/web/20180612143600/https://www.flightglobal.com/news/articles/atr-parent-leonardo-rules-out-100-seat-turboprop-445340/|archive-date=12 June 2018|url-status=live}}</ref>
