Audi AG said the A4 will offer three gasoline and four diesel engine choices in Europe, but Dahncke said the engine lineup is still being finalized for the U.S.
A 2.0-liter TFSI gasoline engine is confirmed for the U.S. and a 2.0-liter TDI or diesel engine will also be available, but probably not at launch, Dahncke said.
The engine lineup will include new versions of the S tronic, tiptronic and manual transmissions.
"We will not be releasing specific information for the U.S. for a while," he added. "The big news for U.S. consumers is that the car is dynamically much better, with more usable space and with an advanced MMI (Multi Media Interface)."
The A4, which is Audi's best-selling model, shed 265 pounds in the redesign compared to the 2015 model. It is larger than the outgoing model, growing in length to 15.5 feet. The wheelbase has widened to 9.3 feet, which increases cabin space and rear-passenger legroom. The styling changes are evolutionary.
Handling is significantly improved, thanks to all-new electromechanical power steering and re-engineered forged aluminum five-link front and rear axles.
An optional Audi virtual cockpit is fully digital and features a 12.3-inch LCD screen. The high-end MMI Navigation plus has a 4G LTE connection and Wi-Fi hotspot.
Many of the new driver-assistance systems will be offered in the U.S., although specifics have not been provided at this point. A "predictive efficiency assistant" that helps drivers to save fuel has not been confirmed for the U.S.
Edmunds says: The 2016 Audi A4 should prove to be an even more compelling choice for car shoppers next year.
