The MKZ is smack-dab in the middle of one of the most hotly contested luxury segments, against the likes of the Acura TL, Lexus ES 350, Infiniti G35, Chrysler 300C, Cadillac CTS and many others. Few offer all-wheel drive like the MKZ, but many have luxury pedigrees that exceed Lincoln’s current credentials. Perhaps the closest competitor is the Infiniti G35. The price starts at $31,450, climbing to $33,950 for the all-wheel drive G35x. It offers a 306-horsepower 3.5-liter V6 engine, five-speed automatic transmission and standard stability control, HID bi-xenon headlights, leather upholstery, automatic climate control and 17-inch alloy wheels. It offers more power than the MKZ but without much of an economy penalty.
