Don't call this cat a pussy. Jaguar pounces with the meaner, faster and more powerful 2010 XFR ($TBA). The new XFR receives a supercharged 5.0-liter V8 engine rated to produce 510-horsepower and 460 pound-feet of torque. Although electronically limited to 155 mph, this Jag is still capable of whiplash acceleration from zero to 60 in 4.7 seconds. Other enhancements include a set of new 20-inch Nevis aluminum wheels, aluminum hood with dual air extractors, front fenders and fascia, rear boot lid spoiler and bumper with quad-exhaust and dark aluminum trim interior.
