Gulfstream’s Switch to PurePower for G500/600 Engines Pays Off
The G500 and G600 are powered respectively by Pratt & Whitney Canada’s PW814GA and PW815GA turbofans.

Gulfstream’s decision to switch to Pratt & Whitney Canada (P&WC) as the engine provider for its new G500 and G600 large-cabin business jets appears to be vindicated even ahead of type certification for the new models. P&WC tapped the PurePower technology it developed for the PW1000 family of regional airliner engines to come up with the 15,144-pound-thrust PW814GA engine and 15,680-pound-thrust PW815GA that, respectively power the G500 and the G600.
