The BMW 4 Series is great to drive, smart inside and roomier than you might imagine. With its powerful engine the M440i is great fun, but the 420i strikes the best balance between performance and running costs while still impressing on a twisty road.
M Sport trim comes with plenty of standard goodies, including 18in alloys, leather seats (heated in the front), cruise control and climate control. We’d recommend forking out extra for adjustable lumbar support and the M Sport Pro pack if you can.
This fuel-sipping diesel feels more muscular than the 420i from low revs and is boosted by mild hybrid technology. Pricier to buy than the petrol and not as keen to rev, though.
