DETROIT — The El Camino moniker — a sentimental favorite despite its Chevrolet roots — lost out to the G8 ST in a promotion to name the new Pontiac sport truck. The 2010 Pontiac G8 ST will debut in late 2009, the automaker said.Pontiac said more than 18,000 names were submitted during a 'Tame the Name' promotion. While not giving out total vote counts, the Pontiac powers-that-be said G8 ST was 'one of the most popular suggestions.''We actually thought very long about El Camino,' said Craig Bierley, Buick-Pontiac-GMC product marketing manager for cars and crossovers. 'In the end, we felt it was more appropriate to honor the El Camino's unique place as part of Chevy's heritage and not use that nameplate on a Pontiac.'The quirky El Camino has a unique place in automotive history as a cross between a coupe and a truck.Pontiac says the G8 ST will share the 'basic architecture and 361-horsepower V8 as the G8 GT performance sedan.' It will have a 73.9-inch cargo bed, a six-speed automatic transmission and a payload of 1,000 pounds.What this means to you: El Camino will take its place in history as Pontiac moves forward with the G8 ST. — Anita Lienert, Correspondent
