2004 Pontiac Bonneville GXP Road Test
Will upping the power ante by dropping GM's exceptionally smooth and refined 275-horsepower, DOHC, aluminum 4.6-liter (278 cu-in) Northstar V8 into the Bonneville be enough for the big sedan to claim domestic 4-door dominance? Pontiac certainly hoped so while it was in development, but now that powerful new Chrysler's 300C has taken the country by storm hoping may not be enough. After all, "That got a Northstar?" has hardly become a pop-culture catchphrase.
