Mitsubishi Outlander — MPG & Fuel Costs 2025
Mitsubishi's popular mid-size SUV, famous for its pioneering Plug-in Hybrid (PHEV) version that dominated the UK market.
The third-generation Mitsubishi Outlander became a massive sales success in the UK thanks to the PHEV version, which offered low company car tax rates and high efficiency.
It combines a petrol engine with two electric motors and a lithium-ion battery. Standard 2.2-litre DI-D diesel versions were also available for high-mileage drivers.
Real-world fuel economy is around 44 MPG for the diesel. The PHEV can return over 80 MPG if plugged in regularly for short trips, but averages around 35-38 MPG when run on petrol alone.
