| Bottom line | The 2013 Infiniti M56 is plenty powerful, but its true strengths are its safety and its cabin. Save your money and opt for the smaller engine. | The conservatively styled 2013 Audi S6 Quattro is a high-tech sport sedan that makes few compromises where cabin technology, on-road performance, and optional safety features are concerned. | The 2014 Acura RLX makes a game attempt at being a high-tech roller, but suffers from flaws serious enough that they should send Acura back to the drawing board. |
