With the introduction of the M5 in the mid-Eighties, a new executive saloon segment was created. Ever since, BMW
's rivals have been building models to match the might of the M5. In 2004, a challenger in the form of GM's Cadillac
CTS-V burst onto the scene and in 2008 the second-generation car was revealed. Sporting a 556hp, 6.2-liter supercharged V8, the CTS-V, good for a 0-60mph time of 3.9 seconds, was a fierce competitor to the E60 M5 with its 500hp, 5.0-liter V10.
