“The last of the V-8 Caddys – the (very) limited production CTS-V sedan/wagon – is being retired. There appears to be a replacement on deck for 2016”
Will the replacement be a smaller cubed V8? Maybe a 5.3L?
Then let us not forget the turo-charged Buick Grand Nationals of the late 80s. With todays technology the V6 could put out some serious horsepower for GM.
