Audi A3 vs Audi A4: Exterior & Interior Dimensions

Depending on the size of your family or the amount of space in your neighborhood (like for city parking), you may be looking for a different car size. So, you'll definitely want to take a closer look at the dimensions of both sedans.

The Audi A3 is the smaller of the two cars, both inside and out. As far as the exterior goes, the A3 is 175.5 inches long with a 103.8-inch wheelbase. Comparatively, the Audi A4 is 186.1 inches long with a 111-inch wheelbase.

Likewise, the interior room tends to vary, too. The A3 is a spacious vehicle, with 41.2 inches of front legroom and 35.1 inches of rear legroom. However, as we already mentioned, the A4 offers a bit more interior room, with 41.3 inches of front legroom and 35.7 inches of rear legroom.

Cargo room varies slightly, as well. In the Audi A3, you get 12.3 cubic feet of trunk space. The Audi A4, meanwhile, offers 13 cubic feet of trunk space. However, they both have 40/20/40 split-folding rear seatbacks, so you can fit larger items while still leaving room for a backseat passenger or two.

2019 A3 & A4 Cabin Amenities

Both sedans offer plenty of amenities to help keep everyone happy. One of them is heated front seats to stay cozy when it's chilly out. However, the Audi A4 also offers heated rear seats and a heated steering wheel, which could come in handy on especially cold nights.

The A4 also offers 8-way power front seats to easily get comfy for longer drives. However, the Audi A3 may leave you feeling a bit more relaxed, as it offers 12-way power front seats.

Inside the A3, you'll find a dual-zone automatic climate control system. This feature allows the driver and front passenger to individually adjust the cabin temperature. So, if you need to warm up while your co-pilot wants to cool down, you can both be happy with this feature.

However, the A4 offers a three-zone automatic climate control. With this feature, the backseat passengers can also adjust the cabin temperature, so everyone on board can be comfortable.

Additionally, there are plenty of storage options inside both models. These include four beverage holders and a grocery hook (with the latter being available in a storage package). In that same storage package for these sedans, you'll find USB charging ports for the rear seats. With this feature, the people in the back can always have a fully charged mobile device for their peace of mind.

Cutting-Edge Technologies in the Audi Sedans

Technology is a key facet of any Audi that you choose. While the A3 and the A4 have many of the same gadgets, there's still some differences between their offerings.

Just take safety tech, for example. Audi pre sense® is the centerpiece of each car's array. This smart technology can predict when accidents are going to occur and act autonomously to prevent them. While each car features the basic version, the Audi A4 also comes with the city version, which can initiate braking at speeds of up to 52 MPH.

Their entertainment suites vary slightly, as well. Each vehicle comes with features like Bluetooth®, an SD card reader, and a robust sound system. However, the new A3 offers a 14-speaker Bang & Olufsen® Sound System, while the available system in the Audi A4 has 19 speakers.

However, each vehicle does share many of the bigger features that drivers may be more intrigued by. This includes a trial subscription to SiriusXM® Satellite Radio. With over 100 music, news, and comedy stations to choose from, you'll never run out of anything new to listen to.

This also includes Apple CarPlay® and Android Auto™ smartphone integration. To use, simply plug your mobile device into the car's USB port. You can then listen to audiobooks, pull up directions, and more, without needing to touch your phone while driving.

A3 vs A4: Audi Performance Specs

Just as you might imagine, the powertrains in these two sedans are simple. Each automobile features a 2.0L 4-cylinder engine that's mated to a 7-speed S tronic® dual-clutch transmission.

However, despite having the same mechanics, the A4 produces a bit more power. It delivers 188 horsepower and 236 lb-ft of torque. The A3, on the other hand, delivers 184 horsepower and 222 lb-ft of torque.

While their power ratings differ slightly, they can each give you optimum traction on the road. Both the A3 and A4 are available in quattro® all-wheel drive. This system can intuitively distribute power between all four wheels when needed to help you travel on even the slickest surfaces with ease.

Depending on what area of South Florida you live in, be it Miami, Hollywood, or Miami Beach, you may prefer a bigger sedan, such as the Audi A4. Otherwise, the smaller Audi A3 may be better fit. The decision is entirely up to you.
