Bombardier redesignates CSeries variants as CS100, CS300

On the back of the confirmation of Lufthansa's deal for up to 60 Bombardier CSeries aircraft, the Canadian manufacturer has redesignated the models in the twin-jet family.

The 110-seat CSeries, which is the lead variant due to enter service in 2013, is designated the CS100. This model had previously been known as the C110. The 130-seat aircraft, which was formerly the C130, is now designated the CS300.

Bombardier says the two-model family, which will be powered by Pratt & Whitney's PW1000G geared turbofan, will benefit from the latest technological advancements.

These will including fourth-generation aerodynamics, increased use of composites and advanced aluminium alloys in structures, and the latest system technologies such as fly-by-wire and electric brakes. The composite wing will feature a fourth-generation transonic design.

Bombardier claims the CSeries will emit 20% less carbon dioxide and 50% less nitrous oxide, fly "four times quieter", and deliver 20% lower fuel-burn with 15% better cash operating costs versus current similar-sized aircraft. It bases this claim on a 500nm [925km] route "in a North American operating environment".

Lufthansa's supervisory board has approved a commitment placed at the Farnborough air show last year for 30 CSeries firm orders, plus 30 options. The aircraft will be used by its Swiss International Air Lines subsidiary.
