Frankfurt Motor Show 2015 preview - Pictures

<span>Alfa has turned to Ferrari for its flagship engine. It’s a 3.0-litre V6 Bi-turbo petrol unit, pumping out an astonishing 503bhp.</span>

Seeing a car this size tackle a rock slope is just as impressive as seeing a bear climb a tree.&nbsp;

All engines emit less than 150g/km of CO2, and the diesels are true economy champions. The sDrive18d emits just 114g/km of CO2 and returns a claimed 68.9mpg.&nbsp;

The driving experience in the GLC has been designed on comfort and refinement.&nbsp;

The 6.6-litre turbocharged V12 is promised to be whisper quiet.

Under the skin, Mercedes has concentrated on making the Cabriolet as strong and stiff as possible.

The 308 GTi takes on the Ford Focus ST and SEAT Leon Cupra.

Official pictures of the fourth-generation Renault Megane have been revealed, ahead of its launch at the 2015 Frankfurt Motor Show.
