The 5 Engines That Have Powered Airbus A320-Family Planes

The 5 Engines That Have Powered Airbus A320-Family Planes
The Airbus A320 stands as a benchmark in commercial aviation, renowned for its innovation and widespread popularity. Since its launch in 1984 and first flight in 1987, the A320 family has become the world’s best-selling commercial aircraft series, surpassing the Boeing 737 in total orders in 2019. With more than 19,000 orders and nearly 12,000 deliveries, the A320’s success is closely tied to its versatile engine options—a key factor in its global appeal.
From the outset, Airbus offered customers a choice of engines, a strategy that has shaped the A320’s evolution. The original A320ceo (“current engine option”) models were powered by either the CFM56-5 series from CFM International or the V2500 from International Aero Engines (IAE). More recently, the A320neo (“new engine option”) and A321neo variants introduced advanced powerplants: the CFM LEAP and Pratt & Whitney PW1100G, both promising improved efficiency and lower emissions.
Engine Options and Their Impact
CFM56-5A: The Original Workhorse
- Thrust: 22,500–26,000 lbf
- Bypass Ratio: 4.9:1
- Fan Diameter: 68.3 in (1.73 m)
- Length: 2.5 m (98 in)
The CFM56-5A, developed by CFM International—a joint venture between GE and Safran—powered the A320’s maiden flight. Building on earlier CFM56 models, the -5A offered higher thrust and advanced materials. The A320-100, the family’s first variant, entered service in 1988 with this engine, followed by the more successful A320-200. The CFM56 series has since become the most widely used commercial jet engine, with over 33,000 units produced and more than one billion flight hours logged. While the majority power Boeing 737s, over 10,000 have been installed on Airbus aircraft.
IAE V2500: Efficiency and Reliability
- Thrust: 22,000–33,000 lbf
- Bypass Ratio: 5.4:1
- Fan Diameter: 63.5 in (1.61 m)
- Length: 3.0 m (118 in)
Formed in 1983, IAE brought together Pratt & Whitney, Rolls-Royce, Japanese Aero Engine Corporation, MTU Aero Engines, and Fiat to develop the V2500. Certified in 1988, the V2500 offered A320 customers an alternative to the CFM56, with comparable thrust but greater fuel efficiency and lower emissions, thanks to its higher bypass ratio. Its quieter operation also suited airports with strict noise limits. The V2500 has become a mainstay on the A320, valued for its reliability and performance.
New Generation Engines: CFM LEAP and Pratt & Whitney PW1100G
The introduction of the A320neo and A321neo brought new engine choices: the CFM LEAP and Pratt & Whitney PW1100G. Both engines deliver significant improvements in fuel burn, emissions, and noise, reflecting the industry’s push for sustainability. However, these advanced engines have also presented challenges. Technical issues and supply chain disruptions have led to delays and maintenance headaches for airlines and Airbus alike, complicating production schedules.
Industry Challenges and Competitive Landscape
Engine reliability and availability have become central concerns for Airbus, especially as the company contends with global supply chain disruptions and labor shortages. These issues have slowed deliveries and increased maintenance demands. Meanwhile, Boeing, Airbus’s chief rival in the narrow-body market, faces its own engine and certification hurdles, intensifying competition as both manufacturers strive to meet surging demand.
Despite these challenges, the A320 family’s adaptability and range of engine options have cemented its status as a leader in commercial aviation, powering airlines worldwide through decades of change and innovation.
