Road Tests

The Audi A6 2.0 TDIe is a large, good-looking executive saloon that can also achieve 53.3 mpg, but are there any downsides?

We like the new Astra, but does the ecoFLEX treatment ruin a perfectly good car?

The Audi A3 1.6 TDI, with the help of Start/Stop technology, emits just 99 g/km CO2, which is very impressive for a premium-badged car.

The new BMW 5 Series was launched in March, but the 520d has only just arrived; its emissions of 129 g/km CO2, together with 57.6 mpg, are class-leading for a large executive saloon.

The Nissan LEAF is due to be the UK's first mass-produced all-electric five-seat family hatchback, and Green-Car-Guide has driven the final pre-production car.

The Skoda Octavia Greenline Estate is one of the most sensible purchases you can make if you want lots of space, high mpg, and good value, but there's one interesting question: should you choose the Greenline over the standard model?

Yes, Saab is still alive; the company's new 9-5 model is here and it offers an interesting alternative to the more obvious mainstream choices.

The Volvo V50 Estate 1.6D DRIVe Start/Stop has incredibly low emissions of just 104 g/km CO2, which is certainly class-leading for an estate of this size.

The Renault Megane Coupe 1.5 dCi 86 is a good-looking car that also manages 64.2 mpg, along with emissions of just 115 g/km CO2, so is this the best green coupe?

The Volkswagen Passat BlueMotion 2 1.6 TDI manages 64.2 mpg, emits 114 g/km CO2, and has a range of almost 1000 miles on one tank, so is this the ultimate efficient saloon?
