Nissan Juke Kuro – the Juke Black

The Nissan Juke Kuro - 'Black' to you and me How did we miss a limited edition Juke – especially when we think the Nissan Juke is such a funky little urban car – when Nissan sent us the details of the Juke Kuro last week? There must be a hole in our inbox. No matter, we’ll make up for it now, although there’s not an enormous amount to say.

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.

Porsche 918 Spyder laps Nurburgring in under 7 minutes

The Porsche 918 Spyder (pictured) laps the Nurburgring in under 7 minutes When the McLaren P1 was first revealed, Ron Dennis told us it would lap the Nurburgring in under 7 minutes. But it seems the best the McLaren P1 has managed so far is a 7:04, so it’s no surprise McLaren hasn’t officially declared its time as they probably knew it wasn’t enough, but also knew that Porsche has managed to take the new 918 Spyder round the ‘Ring in just 6:57s. That 6:57 by the Porsche 918 Spyder isn’t quite as quick as the Radical, but as the Radical has only single type approval, Porsche are justifiably claiming the 918 Spyder’s time as the quickest by a proper production car, beating the previous record of 7:11s set by the Gumpert Apollo.
