With a supercharged Northstar V8 displacing 4.4 liters and making 443 horsepower, the Cadillac XLR-V isn’t a threat to the Dodge Viper on paper. However, priced at about $100,000 and loaded with luxury features along with a standard retractable hardtop, this crunked-up Caddy is a terrific alternative for people who don’t want the rough and raw Viper experience.
