Delivery rates continued to climb during the late 2010s, reaching a total output of 33 CSeries in 2018 and after the Airbus partnership, rising to 48 A220 (new aircraft name) during 2019. Airbus CFO Harald Wilhelm predicted a production potential of more than 100 A220 per year. Production was then to be ramped up reaching ten per month in Mirabel and four per month in Alabama by the mid-2020s. The market share was split between 80% A220-300 (former CS300) and 20% A220-100 (former CS100).
