Ford Motor said today that last month a 2022 F-150 Lightning ran the Ike Gauntlet towing 10,000 pounds*. Ike gauntlet is an 8-mile stretch of I-70 in Colorado that ascends at a 7% incline to a maximum elevation of 11,158-ft. above sea level around the Eisenhower Memorial Tunnel. Ford also said the F-150 Lightning was tested on the extreme grades of Davis Dam. With ground temperatures reaching a high of 118-degrees Fahrenheit during testing, F-150 Lightning pre-production units towed the same 10,000-pound trailers for multiple loops across the dam.
