The motor vehicle brand name with more capital intensive high-performance route Jaguar series. To riff on Neil Young, “Is it better to do a burnout, or fade away?” Jaguar appears to have the answer in the form of two black stripes on the pavement with the 2012 XKR-S series. The current XKR-S has been introduced at the 2011 Geneva Motor Show, the XKR-S builds on the already-hotter XKR, delivering 550 horsepower and 502 pound-feet of torque from its Roots-supercharged 5.0-liter V8 (the cooking XK makes do with 385/380 and the XKR yields 510/461) routed through a paddle-shifted six-speed automatic. It’s an impressive car just like as drivetrain made all the more so by its aural bark, a signature bellow made possible by an active exhaust system that will make you want to leave the windows down and irk your neighbors. Adding all of the go-faster bits seen here to a classically beautiful frame like not have in other brands of cars. Nothing like some high-strung exotics, the drivetrain and brakes are seemingly happy to amble along.
