2018 Audi A4: What's New, Specs & Features
Last updated August 4, 2026
The 2018 Audi A4 gets a light equipment update rather than a redesign. The main change is more standard comfort and driver-assistance equipment, especially on Premium Plus and Prestige trims.
About the 2018 Audi A4
B9 generation, second model year in the U.S. for both the redesigned A4 sedan and the returned A4 allroad.
Audi positions the A4 family as a compact luxury daily driver that blends clean design, a high-quality cabin, brisk turbo power, and advanced in-car technology without feeling flashy or complicated. The sedan aims at shoppers who want a polished sport-luxury car for everyday use, while the allroad adds wagon cargo room and light-duty rough-road ability. Across the family, Audi leans on interior quality, smart digital displays, and all-weather confidence to separate the A4 from rival compact luxury cars.
The Premium trim covers the luxury basics with leather, heated power front seats, three-zone climate control, Apple CarPlay, and Android Auto. Premium Plus is the technology-focused middle trim, with a 12.3-inch digital instrument display and navigation, while Prestige adds features such as a head-up display, premium audio, and the broadest driver-assistance suite. The new Ultra Prestige combines that top-trim equipment with the front-wheel-drive, efficiency-focused Ultra sedan.
What changed, by category
Safety
Blind-spot monitoring with rear warning support becomes standard on Premium Plus. Prestige makes a broader driver-assistance package standard, including adaptive cruise control with low-speed traffic assistance, lane-keeping assistance, traffic sign recognition, and automatic high beams.
Tech and comfort
Heated front seats become standard throughout the lineup. Premium Plus also makes its digital instrument display, navigation, wireless phone charging, and rear USB ports core equipment, while the front-wheel-drive Ultra Prestige joins the trim range.
Styling
Premium sedans with quattro all-wheel drive add S line exterior details.
