Bombardier C-Series

The Bombardier C-Series is Airbus' and Boeing's most prominent rival. Although the Canadian airplane maker has long been a major player in regional airliners, the C-Series is the first time the company has had to compete against the US and European titans.

The Bombardier airliner has, thus far, struggled to net the level of sales as the 737 and the A320. But the C-Series has garnered critical acclaim for its performance, fuel efficiency, and design.

The C-Series lineup consists of two variants of the plane — the 133-seat CS100 and the 160-seat CS300. In the marketplace, the C-Series competes against the Boeing 737MAX7 and the Airbus A319neo.

Like the A320neo, the C-Series is powered by a version of Pratt & Whitney's revolutionary geared turbofan engines — the PW1500G. The Bombardier C-Series entered commercial service in 2016 and has more than 300 firm orders for the plane.
