If you’re looking for a large, stylish, and economical executive estate, then the Audi A6 Avant 2.0 TDI, capable of 56.5 mpg, should fit the bill.

The BMW X1 sDrive20d EfficientDynamics offers rear-wheel drive handling in a compact SUV package returning 62.8 mpg and 119 g/km CO₂ emissions.

The Jaguar XF 2.2 Diesel, returning 52.3 mpg and emitting 149 g/km CO₂, is the most economical Jaguar ever, so does it still have the luxury sporting nature expected of the brand? 

The Peugeot iOn is an all-electric city car that needs no petrol, emits zero-CO₂ tailpipe emissions, and makes complete sense for driving around cities such as London, especially for businesses.

The £7,795 Kia Picanto happened to be our press car when we visited Bentley to see how a £225,000 Bentley Mulsanne is built - so could we live with the Picanto after spending the day with a factory full of Bentleys?

The Peugeot 308 e-HDi 112 offers 62.8 mpg economy and emissions of 118 g/km CO₂ in a practical family hatchback package for less than £20,000.

Having been disappointed with the fun factor of the front-wheel drive cars in the recent Wales Rally GB in Clocaenog Forest, we thought we’d see if the new 65.7 mpg MINI Cooper SD Coupe offered any more smiles in this environment.

We're back to Clocaenog Forest yet again, for the third time in just a few weeks, this time in the MINI Cooper SD Coupe - can it really combine 65.7 mpg and fun? - and what's it like to drive on ice? Watch the video.

The Peugeot 508 Active e-HDI 112 was fresh from taking part in the RAC Future Car Challenge, but could it cope with the challenge of driving to Clocaenog Forest in North Wales, where the RAC Rally last visited back in 1996?

The BMW 520d EfficientDynamics Saloon has a combined economy figure of 62.8 mpg and emissions of just 119 g/km CO2; surely such supermini-levels of emissions mean that this must be an ‘eco-special’ with compromises?
