Deutsche Aircraft revives Dornier legacy with sustainable next-generation turboprop

According to Deutsche Aircraft’s stated mission: “Developing the most advanced, energy-efficient, and cost‑effective 40‑seater regional turboprop: the D328eco.” They add that their values include “Sustainability; Collaboration; Openness; Respect; Excellence (rooted in German engineering/design quality).”

The new D328eco features a stretched fuselage—about two meters longer than its predecessor—to accommodate up to 40 passengers. It will use Pratt & Whitney Canada PW127XT-S engines designed for improved fuel efficiency and lower emissions. The aircraft can operate on 100% sustainable aviation fuel (SAF), which could reduce CO₂ emissions by up to 95% compared to conventional fuels.

In terms of performance, the D328eco maintains short-field capabilities similar to the original but offers enhanced range, payload capacity, and operational flexibility. It is engineered for unpaved runway operations and steep approaches suitable for remote or constrained airports. Its cruise speed is approximately 324 knots with a service ceiling of 30,000 feet.

A comparison between old and new models shows that while the original carried about 30–33 passengers at a maximum takeoff weight of nearly 14 metric tons, the D328eco increases capacity to 40 seats with a higher maximum takeoff weight of over 15 metric tons. Fuel consumption at cruise drops significantly in the new version—around 480 kg/h—resulting in lower operating costs.

The manufacturer also introduces a multi-role variant called D328MR (Multi-Role), which can be adapted for medical evacuation, surveillance missions, cargo transport or VIP shuttle duties. This model supports rapid cabin reconfiguration and can fly nearly 2,200 nautical miles in medevac configuration or remain airborne for over eight hours during surveillance tasks.

Although no firm orders have been announced yet and entry into service has been delayed until late 2027, Deutsche Aircraft positions the D328eco as a future-oriented solution for regional aviation needs.
