BMW 4 Series Review 2026: The Last Great Everyday Coupe?

The BMW 4 Series might be one of the last proper premium coupes left on sale… but is it actually worth buying in 2026? In this review, we test the BMW 420i M Sport on UK roads to find out whether the controversial coupe still delivers the classic BMW driving experience, or if it’s become all style and no substance. We cover: Real-world performance & MPG Back road handling Ride comfort & suspension Interior quality & practicality Rear seat space Tech & infotainment The controversial grille design Whether the 420i is enough… or if you should upgrade to the M440i With 184PS, rear-wheel drive character, a huge boot, and surprisingly good fuel economy, this could be the sweet spot in the BMW range for daily driving. If you’re considering the Mercedes-Benz CLE, a hot hatch, or even waiting for the new Honda Prelude, this review should help you decide.
