BMW i8 plug-in hybrid supercar is more economical than BMW thought

The BMW i8 does 134.5mpg on the official cycle. The production version of BMW’s plug-in hybrid supercar – the i8 – finally arrived at the Frankfurt Motor Show last year offering almost proper supercar price – £100k – along with an almost supercar 0-62mph of 4.4 seconds. What the i8 also offers is ridiculous economy figures thanks to its plug-in hybrid power (and thanks to the daft way official economy figures are calculated) and now, as the i8 gets ready to go in to full production, BMW has revealed that the official economy figures have just got dafter.

Kia CUB concept

Kia gave its new CUB concept its official debut at this week's Seoul Auto Show. The B-segment five-door hatchback was designed at Kia's Namyang Design Center in Hwaseong, South Korea, under the direction of the carmaker's president and chief design officer Peter Schreyer and is less than 4 meters long. Developed as the latest study into Kia's B- and C-segment future models following last year's Trackster concept and the Provo concept unveiled earlier this month at the Geneva show, there are a number of design features taken from the 2007 Kia Kee 2+2 concept.
