BMW 3 Series vs Audi A4: which should you buy?

TL;DR

Both the BMW 3 Series and Audi A4 are excellent choices in the executive saloon market. If you prioritise driving dynamics and sportiness, the BMW 3 Series is the better option, while the Audi A4 offers a more luxurious interior and better fuel efficiency.

Key facts

The BMW 3 Series measures 4709mm long, 1827mm wide, and 1437mm tall, closely matched in size to the Audi A4. The 3 Series offers a more powerful M340i variant with a 386-hp turbocharged inline-six, compared to the A4’s maximum of 261-hp from its turbocharged four-cylinder. The 3 Series is rear-wheel drive, providing a more engaging driving experience, while the A4 features a quattro all-wheel-drive system for enhanced grip. Both vehicles boast premium interiors, but the A4 is often praised for its minimalist design and high-quality materials.

Reliability head-to-head

Both the BMW 3 Series and Audi A4 have solid reputations for reliability. BMW has improved its reliability ratings, often ranking alongside Audi in surveys. However, some users report that Audi’s build quality can feel more robust over time, particularly with interior components. BMW’s servicing costs can be slightly higher than Audi’s, which may influence long-term ownership decisions.

Real-world running costs

The Audi A4 generally offers better fuel efficiency, especially in its diesel variants, making it a great choice for motorway driving. The A4’s engines are tuned for efficiency, while the BMW 3 Series is slightly thirstier but provides a more exhilarating drive. Both cars have similar insurance group ratings, but servicing and maintenance costs for the BMW can be steeper, which is important for budget-conscious buyers.

How they drive

The BMW 3 Series is lauded for its dynamic handling and sporty feel, with its rear-wheel-drive layout contributing to an engaging driving experience on twisty roads. The A4, while competent, tends to feel heavier and more planted, which some drivers may prefer for stability. In urban environments, both cars are agile, but the 3 Series excels in delivering a sportier feel, appealing to enthusiasts.

Tech and interior

Both cars come equipped with advanced technology and high-quality interiors. The Audi A4 features a minimalist design with a focus on digital interfaces, including the Virtual Cockpit, praised for its clarity and functionality. The BMW 3 Series offers a more traditional layout with a driver-focused cockpit and a responsive infotainment system. Both vehicles provide ample comfort and space, but the A4’s interior may feel slightly more luxurious due to its high-end materials.

Resale and depreciation

Both the BMW 3 Series and Audi A4 hold their value relatively well, but the A4 tends to edge ahead. Audi’s reputation for quality and durability often translates into stronger demand in the used market. The 3 Series, while still desirable, may depreciate slightly faster due to its sportier image, which can be polarising for some buyers. The A4 might be the smarter financial choice for long-term ownership.
