After three generations the Mazda CX-5 remains popular, with over five million sold worldwide and more than 103,536 in the UK. The all-new model uses a 2.5-litre e-Skyactiv G petrol engine with 139bhp and 24V mild-hybrid assistance. It offers greater cabin and boot space, a smooth six-speed gearbox and tech upgrades, but suffers engine and tyre noise, bulky city handling and touchscreen quirks.
