What is the Bombardier M170?

DUBAI -- Bombardier appears to be closing in on a new ultra long-range business jet to rival Gulfstream's G650 and replace the company's Global Express XRS.

The new clean-sheet project, says one source familiar with the program, is code named the M170.

Bombardier declined to comment if the M170 was, in fact, the company's new ultra long-range business jet, however the a recent increase in listings in support of a non-descriptive "M170 program" have begun appearing on Canadian job websites.

In response to an inquiry about the M170 designation, the company chose only to say, "We are involved in a number of R&D projects."
