Infiniti’s mid-sized luxury performance machine will get replaced in 2011, but until then, the M can be had with either a 303-hp 3.5-litre V6 or a 325-hp 4.5-litre V8. Both M’s can be had with either rear- or all-wheel drive, and the Sport even offers an active-rear steering system for better handling. Interior starting to date, but the technology offered is more than competitive. Still has what it takes to make BMW sweat.

 

Pros

Still quick in the corners

Cons

Ready to be replaced
