The 2018 Audi A4 combines all you could want in a small luxury sport sedan

The 2018 Audi A4 blends all you could want in a small luxury sedan. It’s quick and comfortable, has a controlled and compliant ride, and comes stocked with infotainment and connectivity. Whether you're slicing through mountain switchbacks or just commuting to work, the A4 is a joy to drive. The roomy cabin handily accommodates four adults, while tasteful design with metal accents makes the A4 feel like a car slightly from the future. That’s reinforced by infotainment features ranging from the high-resolution dashtop display to sophisticated navigation, voice controls, and Apple CarPlay® and Android Auto™ smartphone integration.

The 2018 Audi A4 generates 252 horsepower. Most come with an automatic transmission, but some six-speed manuals are around. An A4 Ultra subtrim offers a less powerful 190-hp engine with higher fuel economy estimates, but we suggest sticking with the regular A4 if you can. The A4’s tech package gives it an edge on the BMW 3 Series and Mercedes-Benz C-Class of the same vintage, but note that in subsequent years both competitors significantly upped their game.

5 reasons to buy the 2018 Audi A4

What We Like

Performance: The A4 is quick and smooth, with a quieter engine than most other turbo four-cylinder-powered competitors. Quiet doesn’t mean slow, though, and the A4 dashes from 0 to 60 mph in just over 5 seconds. The all-wheel drive and sport suspension mean the A4 has impressive traction and neutral handling through curves and corners.

Interior: The A4’s stylish and functional cabin is a showpiece of fit and finish. There’s a clear emphasis on blending cutting-edge tech with a welcome and luxurious environment. The design is simple and elegant, highlighted by thoughtful placement of commonly used controls combined with innovative thinking. The optional digital gauge cluster ingeniously re-creates the look of analog gauges and also displays navigation and entertainment information. You’ll find sufficient legroom for four adults and plenty of room for getting in and out.

Comfort: Like most sedans in this sport-luxury class, the A4 favors the former over the latter. The standard suspension delivers a firm ride with controlled body motions and no real impact harshness. It’s a good balance of comfort and control. The optional sport seats are great thanks to adjustable thigh support, but you can’t go wrong with the standard seats. The optional adaptive suspension offers a few different dynamic settings, but we wouldn’t go out of our way to find one since some of the settings are overly stiff. Seats are firm but supportive and well shaped for hours of comfortable rides.

What Needs Improvement

Engagement: The Audi A4 is well balanced overall, but the steering is a bit disappointing. Most of this comes down to feel, and the A4 just feels a little numb and distant from the tires. The tuning in the electric power steering unit shares some of the blame. The best steering communicates to the driver what the tires are doing via resistance, effort, and weight, but those characteristics feel a bit artificial in the A4. Most drivers probably won’t be bothered by this, and many may never notice. But drivers who like to dash through tight turns may occasionally be frustrated.
