Compare the Audi A5 vs BMW 4 Series
AI generated from our expert reviews
Choosing between the Audi A5 and the BMW 4 Series means balancing equipment, technology and daily comfort. Finding a good driving position is easy in both cars thanks to plenty of adjustment in the driver's seat and steering wheel, and both feature wireless Apple CarPlay and Android Auto. Once you settle onto the motorway, both cabins stay relatively peaceful with minimal wind and tyre noise, though in the back seats, taller adults approaching six feet will find headroom tight in either car. For equipment, the A5 includes adaptive cruise control as standard, whereas in the 4 Series it costs a fortune as part of an optional pack. The A5 also allows you to configure its digital instrument display to suit your needs, while the 4 Series offers no such view personalisation. However, BMW gives you an unlimited-mileage warranty for three years, where Audi caps its three-year cover at 60,000 miles.
