Audi Prologue concept, 2014 Los Angeles Auto Show
Another technology highlight is a new all-wheel-steering system. Called dynamic all-wheel steering, the system allows rear-wheel steering angles of up to five degrees, which helps make it easy to maneuver when parking and makes steering adjustments more accurate and stable at higher speeds.
Power comes from Audi’s familiar 4.0-liter TFSI, which in the Prologue has been tuned to deliver a massive 605 horsepower and 553 pound-feet of torque (with overboost). It accelerates the concept from 0-62 mph in just 3.7 seconds, which isn’t bad considering the vehicle weighs a hefty 4,365 lbs. The transmission is Audi’s eight-speed tiptronic automatic.
One final new feature presented on the Prologue is a new 48-volt subsystem of the vehicle electrical system. Soon to be featured on Audi's production cars, the system helps power all of the ancillaries and draws its power from a motor-generator that recovers energy during braking, thus helping to conserve fuel by taking some load off the engine.
As for production version of the Prologue, Audi has long been rumored to be considering a new flagship positioned above the A8, the alleged A9, so could the concept also be a preview of this flagship, a potential Mercedes-Benz S-Class Coupe rival? We certainly hope so as the clean lines and dynamic proportions of the Prologue are just begging to be put into production.
