2018 Audi A4 Overview

Is the 2018 Audi A4 a Good Used Car?

Yes, the Audi A4 is a first-rate luxury small car. Models in this lineup include the A4 sedan, the performance-oriented S4, and the separately reviewed A4 Allroad wagon.

There's a lot to love about the 2018 A4:

  • One of the swankiest interiors in the class
  • More standard features than similarly priced rivals
  • Cutting-edge standard and available technology
  • Tech features are intuitive and easy to master
  • Better fuel economy than many competitors
  • Agile handling and a smooth ride

But it has a handful of drawbacks worth noting:

  • Costs to insure, maintain, and repair are higher than for the average luxury small car
  • Some comparable rival models have more powerful engines
  • Steering provides very little feedback

Based on listings for the 2018 Audi A4 on our site, the average price is $36,500. Prices range from $29,700 to $46,000 and vary depending on the vehicle’s condition, mileage, features, and location.

How Much Does the 2018 Audi A4 Cost to Own?

The 2018 A4’s five-year costs for gas, insurance, repairs, and maintenance are projected to be about $29,200, or $5,840 per year. This above-average estimate is primarily due to lofty insurance costs.

Is It Better to Buy a Used or New A4?

The A4 is mostly unchanged for 2019, though Audi did discontinue the optional manual transmission. As a result, you can likely save money while still getting all the bells and whistles of a new model by purchasing a used 2018 A4 instead.

There's also very little difference between 2017 and 2018 Audi A4s. You may be able to save money with a 2017 A4, which marked the transition to a new generation. Shoppers in the market for the latest S4 edition will have to stick with a 2018 model, as this high-performance edition wasn't available for 2017. Models from the previous generation will likely cost even less, though they also have less connectivity features and a smaller trunk.

Which Used Audi A4 Trim Is Right for Me?

The 2018 Audi A4 sedan comes in three trim levels: Premium, Premium Plus, and Prestige. This car is also available as the wagonlike Audi A4 Allroad, which we review separately.

The level of opulence and the amount of safety features increase with every step up in trim level, but all Audi A4s have the same powertrain options. The base setup (which Audi refers to as the 2.0 TFSI ultra ) includes a turbocharged four-cylinder engine, a seven-speed automatic transmission, and front-wheel drive. The upgraded powertrain (dubbed TFSI) increases the horsepower from 190 to 252. This option comes with Quattro all-wheel drive and is paired with either a seven-speed automatic or a six-speed manual transmission. The performance-oriented S4 is even more powerful, cranking out 354 horsepower.

For the best value, we recommend the A4 Premium trim. This entry-level trim is far from austere, with upscale materials such as leather upholstery, a lengthy list of advanced safety features, and a nicely equipped infotainment system.

  • Audi A4 Premium: Standard features in the base Premium trim include leather seats, tri-zone automatic climate control, a sunroof, heated front seats, and push-button start. The infotainment system has a 7-inch display, two USB ports, Apple CarPlay, Android Auto, and a rearview camera. Two bundles of safety technology are included as well: Audi Pre Sense Basic and Audi Pre Sense City.
  • Audi A4 Premium Plus: The Premium Plus trim gets Audi Side Assist with Pre Sense Rear. Other standard features include a 19-speaker Bang & Olufsen sound system, front and rear parking sensors, a proximity key, and memory settings for the driver's seat.
  • Audi A4 Prestige: The top-level A4 Prestige receives even more standard safety features, including traffic sign recognition, active lane assist, high-beam assist, and adaptive cruise control with stop-and-go technology. Navigation, an upgraded MMI infotainment system with an 8.3-inch display and handwriting recognition, a virtual cockpit with a 12.3-inch driver's display, a head-up display, and a hands-free power trunk lid are also included.
  • Audi S4: The S4 is the high-performance version of this sedan. It comes with a 354-horsepower turbocharged V6 engine, an eight-speed automatic transmission, and Quattro all-wheel drive. The two available trim levels – Premium Plus and Prestige – have nearly the same standard features as the corresponding A4 trims.

What Does Audi's Certified Pre-Owned Warranty Cover?

Audi offers a certified pre-owned program for cars five years old or less and with fewer than 60,000 miles. Qualifying vehicles bought under the new-car warranty period have coverage until five years from the vehicle’s original in-service date, with no mileage limitation. Certified pre-owned Audis purchased after the four-year new-car warranty has ended receive an additional one-year/unlimited-mileage comprehensive warranty. This is not an extension of the new-car warranty. The two warranties differ in important ways, so read Audi’s warranty page carefully. Audi CPO models must pass a 300-plus-point inspection.

Among luxury car manufacturers, Audi’s CPO program is about average, according to our research. You’ll find better programs from Infiniti, Lexus, and Jaguar.

How Safe Is the A4?

The Insurance Institute for Highway Safety named the 2018 A4 sedan a Top Safety Pick. It received the highest rating of Good in every crash test. Models equipped with the optional Audi Pre Sense Front system provide the highest level of Superior front crash prevention, and properly equipped models received the second-highest rating of Acceptable for the headlights. Out of five stars, the National Highway Traffic Safety Administration gave the A4 a five-star overall safety rating.

Standard advanced safety features:

  • Audi Pre Sense Basic (a system that prepares the car by rolling up windows and tightening seat belts when it detects an impending forward collision)
  • Audi Pre Sense City (includes forward collision warning, automatic emergency braking, and pedestrian detection)
  • rearview camera
  • rain-sensing headlights and wipers

Available advanced safety features:

  • Audi Side Assist with Pre Sense Rear (a system that readies the car if it senses a collision coming from behind; includes rear cross traffic alert and blind spot monitoring)
  • Audi Pre Sense Front (a system that can turn the steering wheel and apply the brakes if it detects a front collision)
  • adaptive cruise control with stop-and-go technology
  • front and rear parking sensors
  • surround-view camera
  • traffic sign recognition
  • high-beam assist

2018 Audi A4 Versus the Competition

Which Is Better: 2018 Audi A4 or 2018 BMW 3 Series?

The 2018 BMW 3 Series and the Audi A4 are both excellent cars to consider. Between the two, the BMW is more athletic, and its range-topping M3 trounces the horsepower rating of the S4. There is also an optional turbodiesel engine that delivers great fuel economy. On the other hand, if elegant styling, sophisticated technology, and lots of standard features are more important to you, stay with the Audi.

Which Is Better: 2018 Audi A4 or 2018 Mercedes-Benz C-Class?

The 2018 Mercedes-Benz C-Class has many nice attributes, including one of the swankiest interiors in the class. In addition to its sedan body style, the C-Class is available as a two-door coupe or convertible, neither of which are choices with the A4. That said, the Audi A4 is one of the few luxury small cars that can match the C-Class when it comes to interior luxury. Moreover, the A4 has a better predicted reliability rating, costs an average of $3,500 less, and saves the average driver about $600 a year in select ownership costs. These advantages makes the A4 a much better choice.

2018 A4 Performance

How Does the 2018 Audi A4 Drive?

The A4's two turbocharged engines are lively and responsive. They don't quite live up to the potency offered by a 2018 BMW 3 Series or 2018 Cadillac ATS, however. If you want to upgrade your A4's acceleration from quick to blistering, set your sights on the high-performance S4.

Bolstering the A4's fun-to-drive dynamics is a suspension system that imparts an agile demeanor while keeping the ride comfortable. The somewhat numb steering feel is one of the few things professional reviewers complain about.

  • Base engine: 190-horsepower turbocharged 2.0-liter four-cylinder
  • Available engines:
    • 252-horsepower turbocharged 2.0-liter four-cylinder
    • 354-horsepower turbocharged 3.0-liter V6
  • Drivetrain: standard front-wheel drive; available all-wheel drive.
  • Transmission: standard seven-speed dual-clutch automatic (190- and 252-horsepower engines); available six-speed manual (252-horsepower engine only); standard eight-speed automatic (354-horsepower engine only)
Does the 2018 Audi A4 Get Good Gas Mileage?

The base A4 gets good fuel economy for a luxury small car. In comparison, the 2018 Mercedes-Benz C-Class will cost the average driver an additional $250 each year at the gas pump.

  • 2.0-liter four-cylinder, FWD: 27/37 mpg city/highway
  • 2.0-liter four-cylinder, AWD: 24/34 mpg
  • V6: 21/30 mpg

The 2018 A4 seats five people. It comes standard with leather upholstery and heated front seats, which usually cost extra in luxury vehicles at this price point.

How Many Child Car Seats Fit in the 2018 Audi A4?

The 2018 A4 has two complete sets of LATCH car-seat connectors on the rear outboard seats and an upper tether on the rear middle seat. It earned the Insurance Institute for Highway Safety's highest rating of Good for ease of use, as it's easy to find and use every anchor.

2018 Audi A4 Features

The A4 earns high praise for its state-of-the-art technology. You can control the user-friendly MMI infotainment system using uncomplicated voice commands or with an intuitive central knob. With the upgraded system, you can scrawl letters and numbers with the handwriting recognition technology to quickly input an address into the navigation system. The optional virtual cockpit, which replaces the standard driver's gauges, is sure to draw oohs and aahs with its crisp graphics and stunning map display.

  • Standard infotainment features: a 7-inch display, two USB ports, Apple CarPlay, Android Auto, and voice command capability
  • Available infotainment features: handwriting recognition, a navigation system, virtual cockpit with a 12.3-inch display, satellite radio, HD Radio, and a 19-speaker Bang & Olufsen sound system
