In the world of automotive extroverts, the 2024 Audi A4, like its A6 and A8 sedan siblings, is the loud, quiet type. It may not have the pomp and pageantry of some rivals, but it has all-round confidence and style. That means its dynamic abilities too; it’s a premium sedan first, but won’t leave you wanting when the urge for a little fun strikes. Its turbocharged four-cylinder engine has enough muscle to keep things interesting, and standard all-wheel drive and taut suspension tuning bring balanced handling and foul-weather grip. The interior takes on a muted kind of weight, and while it’s carefully assembled with premium materials and attention to detail, a more playful style might lighten the mood. In fact, the same can be said about the relatively quiet exterior styling. But while rivals such as the Alfa Romeo Giulia, Genesis G70, and to a lesser extent the Mercedes-Benz C-class, continue to lead with their looks and follow with more driver involvement, the A4 continues to deliver its own quietly expressed brand. quality, a rare trait in today’s market.
What’s New for 2024?
The A4’s standard equipment list expands for 2024 with the inclusion of adaptive cruise control, lane keeping assist, parking assist and a heated steering wheel; all models except the base A4 40 get the remote engine start function via the myAudi app. The Navigation package adds traffic sign recognition, which also activates Predictive adaptive cruise control. In terms of styling, Arkona White replaces Ibis White across the A4 range and Progressive Red metallic, available on A4 45 and S4 models, replaces Tango Red metallic.
Price and Which One to Buy
The base Premium trim is up $1100 for the 40 and $1000 for the 45, but prices for the rest of the 2024 lineup remain unchanged. Balancing that mark is a new entry for 2024 with adaptive cruise control, lane keeping assist, parking assist and a heated steering wheel as standard equipment. Still, the mid-range Premium Plus trim makes sense because it’s bundled together
18-inch wheels, a Bang & Olufsen sound system, a top-view camera system, a reconfigurable digital gauge display, a wireless charging pad, memory settings for the driver’s seat, blind spot monitoring and a remote engine start function via the myAudi app. We’d suggest the more powerful 45 powertrain—it makes 60 horsepower more than the 40—and it’s a relatively inexpensive $1600 upgrade.
Engine, Transmission and Performance
Audi offers the A4 in two strengths: 40 and 45. Both are powered by a turbocharged 2.0-liter four-cylinder with a 12-volt hybrid system and all-wheel drive; The 40 makes 201 horsepower, while the 45 boosts output to 261. While we like the six-speed manual, a seven-speed dual-clutch automatic is the only transmission. Fully equipped A4 45 we drive sprints to 60 mph in a brisk 4.8 seconds, and the automatic shifts quickly and smoothly. Accurate steering, well-controlled body movements and strong roadholding combine to make the A4 a sharp, if not class-defining, handler. Equally impressive is the damping, which instinctively walks the line between comfort and sharp reflexes with balanced results. Steering feel, which is very important in a sedan with a sporty tone, is calm at low speeds and on the highway. However, almost as if by magic, the steering wheel becomes pleasantly communicative when you push the car on winding roads.
Real World Fuel Economy and MPG
The Audi A4 40 is EPA-rated for 26 mpg city and 35 mpg highway. That’s actually a slight increase of 2 mpg in both measures over the 2023 model. Official A4 45 numbers aren’t in yet, but we expect those numbers to match or be within 1 mpg of 40 in each metric. However, the last A4 45 model we drove on our 75-mph highway fuel economy route, which is part of our extensive testing regimen, returned a solid 33 mpg.

Interior, Comfort and Cargo
Like much of the current Audi lineup, the A4 combines contemporary design cues with sharp technology and quality materials to create a clean and functional upscale cabin environment. Most controls and switches are placed for easy access and operate with a satisfying tactile feel. The A4 does a commendable job of carving passenger space out of its relatively compact footprint. The back seat is spacious, with 35.7 inches of legroom, and the standard sunroof contributes to the spacious feeling. Storage bins and cubbies are on the small side, however, but the trunk offers 12 cubic feet, which is about average for the class. We managed to fit five suitcases into the boot, and the A4’s rear seats fold down in a handy 40/20/40 split, making it easy to fit longer items like poles and skis. Like most sedans in the entry-level luxury class, the A4 is accommodating but not spacious; choose which one A4 Allroad wagon if you need more cargo space.
Infotainment and Connectivity
The A4’s infotainment system consists of a 10.1-inch touchscreen with excellent image quality. For 2024, all A4 45 models get remote start functionality via the myAudi app.
All A4 models on the Premium Plus trim level benefit from the available Navigation package (standard on the Prestige Trim) which now includes traffic sign recognition integrated into the adaptive cruise control. Additional standard features are generous and include Apple CarPlay and Android Auto, two USB ports and voice commands. SiriusXM satellite radio, and in-car Wi-Fi are included in various option packages, as is a more powerful Bang & Olufsen audio system with 19 speakers. A cool digital gauge display that Audi calls Virtual Cockpit is optional, and we highly recommend it.
Safety Features and Driver Assistance
Audi has significantly increased the standard safety content of the A4 and driver assistance features for 2024, making adaptive cruise control, lane keeping assist and parking assist standard. Previously only available on expensive top trim levels, it adds a new layer to the A4’s value. For more information on A4 crash test results, visit the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) website. Key safety features include:
- Standard adaptive cruise control
- Standard automatic emergency braking with forward collision warning
- Standard lane departure warning with lane keeping assist
Warranty and Maintenance Coverage
Audi’s warranty coverage is modest among luxury brands, and it doesn’t offer free scheduled maintenance coverage, unlike BMW.
- The limited warranty covers four years or 50,000 miles
- Powertrain warranty covers four years or 50,000 miles
- No free scheduled maintenance
