Video: GM's Frank Saucedo, Niki Smart and Gael Buzyn on the Elmiraj concept

GM director advanced design Frank Saucedo features in a new video explaining the design process behind the new Elmiraj concept. Saucedo, who oversaw the concept's development at GM's advanced design studio in North Hollywood, California, talks about how the Elmiraj – the second in a series of three concept cars that began with last's year Ciel – is a study of how they can progress and evolve the carmaker's ‘Art and Science' design philosophy. GM's interior design manager Gael Buzyn and exterior design manager Niki Smart also feature, with Smart explaining how the Elmiraj concept is focused on the notion of ‘the drive' and has been designed to reflect dynamism while the Ciel was about ‘the journey', represented by a luxurious interior.

Volvo S60 Review (2014): S60 D4 SE Nav 181 PS manual

This Volvo S60 D4 has the new Drive-E engine Most of the Volvo news of late has been about the new XC90, and Volvo’s new range of engines – the Drive-E range – which look to offer improved economy and emissions with better performance and more flexibility.

Of course, the 2014 S60 may get the all-news Drive-E engine, but it is still a five year old design and runs on a platform that came from Ford in the first place, so although we get a good idea of what the new engines mean for Volvo going forward, the basics of the S60 are far from new.
