The 2018 Audi A4 delivers just about everything we expect from a small luxury sedan. There's quick acceleration, a comfortable ride, and the latest connectivity and navigation technologies. But the fact that it does it without overwhelming you makes it, at least for the time being, the car to get in the segment.
The A4 is a joy to drive, whether you're slicing your way through mountain switchbacks or just tackling your daily commute. On the inside, Audi's understated yet attractive interior design makes operating all of the many high-tech features easy, thanks to the intuitive MMI infotainment system and smartly placed physical buttons for more common functions. To top it off, the A4 also provides plenty of space and comfort for front and rear passengers, accommodating even taller adults in back.
Trust us, you'll want this car on your short list.
Notably, we picked the 2018 Audi A4 as one of Edmunds' Best AWD Sedans for this year.
trim levels & features
The 2017 Audi A4 is a small luxury sedan available in three main trim levels: Premium, Premium Plus and Prestige. A more fuel-efficient A4 Ultra subtrim is also available in conjunction with the Premium and Premium Plus trims. Under the hood is a turbocharged 2.0-liter four-cylinder engine (252 horsepower and 273 pound-feet of torque). The A4 Ultra's engine is less powerful (190 hp and 236 lb-ft of torque) but gets better fuel economy.
Front-wheel drive is standard, with all-wheel drive (called Quattro in Audi lingo) optional. A seven-speed, dual-clutch automatic transmission comes with all A4s. A six-speed manual transmission is also available but only on all-wheel-drive A4s. The Ultra is offered only with front-wheel drive. Unless you really want maximum fuel economy, we'd suggest sticking with the regular A4 engine instead of the Ultra. You'll feel the power difference.
Standard feature highlights for the A4 Premium include 17-inch wheels, automatic xenon headlights, a forward collision mitigation system, adjustable drive settings (Audi's Drive Select), a sunroof, an auto-dimming rearview mirror, leather upholstery, heated power front seats, tri-zone climate control and folding rear seatbacks. Standard technology features include a rearview camera, Audi's MMI infotainment system with a 7-inch central display, Apple CarPlay and Android Auto integration, and a 10-speaker audio system with two USB ports.
The optional Convenience package adds auto-dimming and power-folding side mirrors, keyless ignition and entry, driver-seat memory settings and satellite radio.
Our favorite is the next step up, the Premium Plus. You get the Convenience package features as standard, along with 18-inch wheels, LED headlights, sporty (S line) exterior styling flourishes, front and rear parking sensors, and a 19-speaker Bang & Olufsen surround-sound audio system. Audi's blind-spot and rear-facing crash mitigation system, Side Assist and Pre Sense Rear, is also standard.
The main option for the Premium Plus is the Navigation and Telematics package. This gets you with Audi Connect online services (includes a 4G LTE connection and Wi-Fi), a digital instrument cluster (Virtual Cockpit) and an upgraded version of MMI with an enhanced 8.3-inch display, navigation, voice controls and fingertip-scrawl recognition.
Finally, there's the top-of-the-line A4 Prestige. It comes with all of the above as standard plus a head-up display, additional interior ambient lighting, a top-down parking camera system, lane departure warning and intervention, and upgraded interior trim.
Notable options packages include the Sport, Sport Plus, Cold Weather and Warm Weather packages.
Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our Full Test of the 2017 Audi A4 2.0T Prestige Quattro Sedan (turbo 2.0L inline-4 | 7-speed dual-clutch automatic | AWD).
NOTE: Since this test was conducted, the current A4 has received only minor feature revisions. Our findings remain applicable to this year's model.
