The G650 will be not only the largest Gulfstream ever, but also the fastest and have the most range.All data is preliminary and are the results of Gulfstream’s design review, wind tunnel testing and other analysis. However, Gulfstream has sufficient confidence to release each of these details.The cabin cross-section of the Gulfstream G650 will be 14 inches wider than that of the G550 — a specification that has remained the same since the original GI turboprop from the 1950s. Headroom is also increased by three inches.
