2012 Hyundai Genesis 5.0 R-Spec
This might be the sleeper sedan of the year: Korean manufacturer Hyundai has given their Mercedes-fighting full size car a kimchi kick in the form of a new 5-liter V-8 engine called the Tau, which brings 429hp to the pavement. That powerplant scoots the rear-wheel-drive R-Spec to 60mph in just 5.1 seconds, and thanks to a fancy house-made eight speed automatic transmission, the new engine makes just one less mile per gallon than its smaller V-8 counterpart. Sure, the R-Spec’s derivative styling won’t turn many heads — and it lacks the near-predictive steering feel of its German rivals — but damned if a test drive in this won’t make you think twice about dropping twenty grand more on a similarly-equipped Benz.
