Cadillac will expand the bandwidth of its "v" sub-brand when it appends that letter to the STS this fall. While the CTS-v packs the Corvette's rip-snorting pushrod V-8 coupled to a six-speed manual transmission, in the BMW M3/Audi S4 vein, the STS-v will take on the Jag XJR and Mercedes-Benz E55 AMG. Its 4.4-liter, 440-horse, 430-pound-feet supercharged Northstar V-8 is the most powerful engine ever bolted into a production Caddy. The CTS-v should hit 60 mph in under five seconds, top out at over 165 mph, and circumnavigate the famous Nuerburgring in less than eight minutes, but its mood and manners will be quieter, more comfortable, and genteel than the CTS-v's.
