Bicuspid Aortic Valve. Bicuspid aortic valve (BAV) affects approximately one to two percent of people. It is the most common congenital heart disorder, impacting both the aortic valve (which controls the flow of blood into the aorta) and the thoracic aorta (the major vessel that sends blood throughout the body).
Dodge Charger police vehicles equipped with HEMI engines will be able to go from zero to 60 mph in just 6.0 seconds, while multiple-displacement will keep gas mileage from being unreasonable. The 3.5 liter V6 is the base engine, with 250 horsepower at 6400 rpm and 250 lb.-ft. of torque at 3800 rpm.
The Hellcat V-8 is teamed with an upgraded ZF 8HP90 eight-speed automatic with paddle shifters. Thanks to the wide ratio spreads and two overdrive gears, the Charger SRT achieves 22 mpg in EPA highway tests. A 13-mpg score in city tests drags the combined figure down to 16 mpg, resulting in a $1700 gas-guzzler penalty.
