http://PetalumaHyundai.com 707-981-4203 This year, the Hyundai Azera has gotten a couple of upgrades that make it even more appealing. Its 3.3-liter and 3.8-liter V6 engines are back, but with output increases of 26 and 20 horsepower, respectively. Fuel economy does not suffer as a result; in fact, mileage increases by 11 percent for the 3.3-liter V6 and by about 7 percent for the 3.8. Much of this improvement is due to the Azera's new six-speed automatic transmission that replaces last year's five-speed. In addition, a new "Eco Indicator" gauge helps drivers know when the vehicle is being driven in a fuel-efficient way.
