The base A4 Ultra Premium with front-wheel drive is priced at $35,850, while the top-of-the-line A4 Ultra Premium Plus starts at $39,650. Prices include a $950 destination charge.
The standard 2017 A4 is priced at $38,250, including destination fees. It is on sale now.
The new model is not available with Quattro all-wheel drive.
Audi pegs the A4 Ultra's fuel economy at 27 mpg in city driving and 37 mpg on the highway. The EPA has not posted official fuel economy numbers on the new version of the A4.
In comparison, the standard front-wheel-drive 2017 A4 delivers 25 mpg city and 28 mpg highway, according to the EPA.
The A4 Ultra is equipped with a 190-horsepower 2.0-liter TFSI four-cylinder engine and a seven-speed dual-clutch automatic transmission.
Audi said fuel efficiency is increased in the engine because the compression ratio was increased. Compression ratio is the measure of how much the air-fuel mixture is reduced in the engine's cylinders before being ignited to produce power.
Standard features include the Audi Pre Sense City safety system, a panoramic sunroof and 17-inch wheels. The cabin is equipped with standard ambient LED lighting, leather seating surfaces and three-zone automatic climate control.
The special A4 debuts as gas prices continue to "hold steady," according to AAA.
The AAA Daily Fuel Gauge Report on Wednesday listed the average price of a gallon of unleaded gasoline at $2.13, compared to $2.67 a year ago.
Edmunds says: Premium buyers who are sensitive to pump prices will want to take a second look at the new 2016 Audi A4 Ultra.
