Just finishing the Baja 1000 is a major accomplishment, whether for a fully-prepared race vehicle or a production pickup. Doing it in 38 hours, on an engine that had already seen serious abuse--that's a testament to reliability.
That, of course, is exactly what Ford was after with the feat. But by doing it publicly, they put their faith in their product, as failure would have been widely known. Nevertheless, they started the Baja 1000 with an F-150 fitted with a V-6 EcoBoost engine that had already seen the equivalent of 150,000 hard miles on the dynamometer and towed an 11,300-pound trailer at speed on a NASCAR track, beat its competition in a steep-grade towing contest at Davis Dam, and served as the power for another F-150 used as a log skidder in Oregon.
Brutal doesn't even begin to describe this engine's life, but even so, after 1,061 miles through below-freezing and over-100-degree temperatures, being battered offroad, the 3.5-liter, twin-turbo V-6 pulled through. That should put to rest any doubts about whether it belongs in an F-150.
Whether it'll put an end to cylinder envy for the V-8-loving pickup world is another matter. What does it do for you?
