With 134bhp it offers solid, flexible performance that will pull you up to motorways speeds perfectly easily, even with a fully loaded car. It's our choice, and comes with a 48v mild-hybrid system. That help it achieve competitive CO2 emissions but it’s not RDE2 emissions compliant, which means there's a 4% diesel surcharge if you pay company car tax. We managed a healthy 45mpg with a mix of driving — but it's noisier than its rivals' equivalent engines and not as muscular as larger 2.0-litre rivals.
