What are the key safety features of the BMW 4 Series?

Stability control, multiple airbags and ISOFIX mounts are standard. Later models layer on lane departure warning, automatic emergency braking and adaptive cruise. Strong brakes and solid crash-test scores give it real peace-of-mind appeal.

What engine options are available with the BMW 4 Series?

Take your pick: early cars range from efficient four-cylinder diesels like the 420d to silky six-cylinder petrols like the 440i. The latest generation adds mild-hybrid tech for cleaner power. Most are autos, but a few manuals are still out there.

What are the standard technology and infotainment features in the BMW 4 Series?

iDrive infotainment is the intuitive and reliable backbone, with satnav, DAB, Bluetooth and USB as standard. Higher trims step you up with bigger screens, wireless charging and premium Harman Kardon audio. Even early models feel modern inside.

What is the fuel consumption of the BMW 4 Series?

Diesel 418d and 420d versions can return close to 60mpg, while six-cylinder diesels balance punch with mid-40s efficiency. Petrols average 40 to 45mpg. Real-world figures shift with driving style, but the blend of performance and economy is a strong suit.

What should I check when buying a used BMW 4 Series?

Service history is non-negotiable, as BMW engines need careful oil changes. Look out for electrical glitches, worn tyres or suspension on big-wheel cars, and check that the infotainment runs smoothly. Convertible buyers should test the roof mechanism, too. For extra peace of mind, consider The AA Vehicle Inspection, especially if you're buying privately.

Are BMW 4 Series cars reliable?

Mechanically, yes. The six-cylinder engines in particular are proven workhorses. The most common grievances are electrical sensors, which are usually cheap to fix. Keep on top of servicing, and the 4 Series will reward you with dependable, enjoyable ownership.

The BMW 4 Series at a glance

Simply put, it's the car for those who want a dash of excitement in their daily drive. When BMW spun the 4 Series out in 2013, it wasn't just a name change from the Series 3. The coupe, convertible and Gran Coupe were designed to turn heads and deliver more of that driver-focused sparkle. The first generation (2013 to 2020) is now a sweet spot for value, offering plenty of choice on the used market. The second wave, launched in 2020, cranked things up with bolder styling, sharper infotainment and mild-hybrid tech to keep efficiency in check. Stacking the BMW 4 Series against the Audi A5 or Mercedes C-Class Coupé, it often feels the most engaging behind the wheel, despite a sometimes firm drive on M Sport suspension or larger alloys. It remains desirable thanks to its solidly built cabin, wide range of engines, and confident cornering.

Pros

Fun rear-wheel drive balance
High-quality interior and tech
Strong engine choices

Cons

Firm drive on M Sport models
Rear space tighter than a 3 Series
Some engines can be noisy
