Diesel and Hybrid Family Cars
Skoda Octavia 1.6 TDI CR 88.3 mpg
The Skoda Octavia range now includes a Greenline model which has an official combined economy figure of 88.3mpg along with emissions of 85g/km CO2.
Jaguar XE 74.3 mpg
The Jaguar XE is the most efficient Family Car that we have driven. With outstanding fuel economy on motorway runs combined with good looks it has to be on your long list.
BMW 320d ED 74.3 mpg
The 3 Series blends fun with environmental responsibility better than any rival. When combined with one of the most communicative and adjustable chassis in any saloon car and excellent fuel economy it is going to take a lot to topple the 3 Series from the top of the tree.
Toyota Prius 1.8 VVT-i 94.2 mpg
The 4th generation Prius delivers outstanding CO2 emissions, more practicality, an improved ride and one of the most aerodynamic bodies every produced. If you aren’t after an engaging drive it makes a lot of sense.
Lexus IS 300h 67.3 mpg
The Lexus IS 300h is one of the best sub-100 g/km CO2 cars to drive, with rear-wheel drive, a 2.5-litre petrol engine, and of course an electric motor.
Skoda Rapid 1.2 TSI 90 ps SE 60.1 mpg
Yes the Skoda Rapid has remarkable similarities with the SEAT Toledo, because there is much development- and parts-sharing going on, but 60.1 mpg is not to be sniffed at.
BMW 330e Saloon 148.7 mpg
We like the 330e. A lot. To find out why we think it is the best car in the class, read on.
The C 350 e is a technical tour de force but it has a super foe in the form of the BMW 330e and doesn’t quite manage to dethrone the 3 Series.
Toyota Prius Plug-in 134.5 mpg
With the Prius Plug-in thanks to the Prius mechanicals, fuel economy is also excellent when you run out of electric range.
