Hyundai rolled out a mildly restyled version of the Azera sedan at the Chicago Auto Show this week. We first got a taste of the changes made on the 2011 Azera back in December '09 when Hyundai launched the sedan's South Korean domestic market twin, the Grandeur, in its facelifted form.
The biggest changes to Hyundai's competitor to vehicles such as the Lexus ES350, Toyota Avalon, Nissan Maxima, Buick LaCrosse and Ford Taurus (or at least those are the cars that Hyundai claims that the Azera rivals) are well hidden under the hood.
Both the 3.3-liter and 3.8-liter V6 engines of the 2011 Azera have been enhanced with the use of Dual Continuously Variable Valve Timing (DCVVT) that improves engine breathing on the intake and exhaust camshafts for better fuel economy and lower emissions.
