How about a Mazda 2? Mazda talks about 'rightsizing' - having the optimal engine size for a car rather than chasing economy with small-capacity turbocharged engines. As such, the Mazda 2 uses a 1.5-litre four-cylinder petrol engine, now helped with a small degree of mild-hybrid electrical assistance. Alternatively, consider a Skoda Fabia with the 1.5 TSI petrol engine.
