Driven: Nissan Juke

Nowhere is the fragmentation of established market segments more evident than when thumbing through Nissan's current brochures. The new Nissan Juke, the smallest and most extreme member of Nissan's crossover range, is pitched as an 'urban proof' alternative to more conventional superminis.

Lamborghini Murcielago LP650-4 Roadster

Lamborghini Murcielago LP650-4 Roadster Expected to sport the same 650bhp engine as the Reventon, this LP650-4 looks like it’s going to be one of the quickest open-topped cars there is, with a 0-60 time just over 3 seconds. Just like the Reventon, the LP650-4 looks likely to come in just one colour choice, in this case a matt grey (Grigio Telesta) with orange accents, and dark painted alloys. With the expected launch of the LP670-4 SV happening at Geneva in a couple of weeks, it is unlikely that Lamborghini will show this car, more likely saving it for later in the year for maximum impact.

Kia Urban Compact SUV Concept heading for Geneva Motor Show

Kia is teasing what looks to be an Urban compact SUV come crossover ahead of a reveal at the 2013 Geneva Motor Show. The market for funky, rufty-tufty urban crossovers started with the ugly bug (but appealing) Nissan Juke and continues apace with car makers rushing to fill a desire by car buyers for something butch and small to blat round urban landscapers. Now it looks like Kia re planning to get in on the act with a new urban runaround of their own, with the reveal of a handful of tease photos of a new concept they will be revealing at this year’s Geneva Motor Show in March.
