2018 audi A3 Sedan

The compact A3 Sedan is the smallest and least expensive member of Audi's North American lineup. It aims to deliver buyers a more compact alternative to the A4 while retaining a traditional four-door body style preferred by American drivers. Buyers after a sportier driving experience can opt for the S3 or the range-topping RS 3.

Recent Changes
For the latest model year, the A3 gets an available virtual cockpit and more electronic driving aids. It also gets minor visual updates.

Overview
Stretching 175.5 inches long, 70 inches wide and 55.7 inches tall, the A3 Sedan looks like a shrunken A4 when viewed from the outside. It wears an aggressive look defined by sharp headlights, lightly sculpted flanks, pronounced wheel arches, a discreet spoiler integrated into the rear hatch and triangular tail lamps.

The A3 benefits from Audi's expertise in the field of lightweight construction and the lightest version tips the scale at just 2,755 pounds thanks to a body made largely of hot-formed steel and an aluminum hood. It shares its modular MQB platform with the Europe-only A3 hatchback and several other Volkswagen products including the seventh-gen Golf.

Life Aboard
The A3 Sedan is fitted with a clean, uncluttered dashboard that puts a strong emphasis on function. The highlights include understated styling elements such as chrome-ringed air vents and a simple instrument cluster made up of four analog gauges.

The smallest member of the Audi family can carry five adults and up to 15 cubic feet of cargo.

The A3 Sedan can be ordered with Audi's MMI infotainment system at an extra cost. MMI groups the car's entertainment, connectivity and navigation (if equipped) functions into single operating system controlled by either a knob and a series of buttons found on the center console or a voice recognition function. The centerpiece of the system is a high-definition color screen mounted on top of the dashboard.

Another notable high-tech feature offered on the A3 Sedan is Audi connect, a software that provides a Wi-Fi connection and lets passengers find places of interest, travel information, weather reports, fuel prices and even access satellite images from Google Earth.

Under the Hood
The A3 comes with a 2.0-liter four-cylinder that generates 220 horsepower and 258 lb-ft. of torque, enabling a zero-to-60-mph time of 5.8 seconds. Power is transferred to all four wheels via a six-speed dual-clutch automatic transmission.

Trim level breakdown
Audi offers the A3 Sedan in three trim levels: Premium, Premium plus and Prestige.

Premium comes standard with leather upholstery, a multi-function steering wheel, a panoramic sunroof, a 12-way power driver's seat, a ten-speaker stereo system, a driver information system integrated into the instrument cluster, a 90-day trial subscription to SiriusXM Satellite Radio, Bluetooth connectivity, a SD card slot, automatic wipers and headlights, Xenon headlights, LED tail lamps, power mirrors, parking sensors, a rear-view camera and heated mirrors/washer nozzles.

Prestige builds upon the first two trims with S line exterior trim, navigation, Audi Connect, an upgraded sound system built by Bang & Olufsen and LED headlights.
