2021 Audi A4

2021 A4 Photos
The 2021 Audi A4 is a compact luxury sedan or Allroad wagon that still delivers on the same values that made it such a success over more than two decades: ample amenities, quietly handsome styling, and buttoned-down performance. Its stoic persona remains intact even after all these years of success.

Changes are minimal for 2021. The base powertrain now comes standard with all-wheel drive. All models but the S4 gain 13 horsepower due to a new 12-volt mild-hybrid system. Wireless Apple CarPlay and an integrated toll transponder have been made standard.

There's nothing new in the powertrain department, where a 2.0-liter turbo-4 continues to hold sway under the hood. Base models use a 201-hp turbo-4 known as the 40 TFSI, but buyers can opt for a 261-hp variant known as the 45 TFSI. Both tunes use a 7-speed dual-clutch automatic that sends power to all four wheels.

Speed freaks will want to check out the S4, which tosses aside the turbo-4s in favor of a 349-hp turbo-6. It pairs to an 8-speed auto and all-wheel drive; all this hardware opens the door to 4.3-second 0-60 mph runs.

The EPA has yet to run the AWD 40 TFSI through its fuel economy tests, but expect it to be thriftier than the 45 TFSI's 24 mpg city, 32 highway, 27 combined. The Allroad is rated at 23/31/26 mpg. At the rear of the pack is the S4 at 20/27/23 mpg.

Automatic emergency braking is standard. Other driver-assist features are optional, including adaptive cruise control blind-spot monitors, and a surround-view camera system.

The IIHS and NHTSA both affirmed the crashworthiness of the A4, with the NHTSA awarding it a five-star overall rating and the IIHS naming it a Top Safety Pick.
