CONFIRMED: McLaren P13 will arrive in 2015 to take on Porsche 911 & Audi R8

McLaren has confirmed the McLaren P13 will arrive in 2015. The original plan for McLaren’s new range of supercars was that the 458-bashing 12C would arrive first (which it did) followed by a more affordable mid-engined car – think nearer £100k than £200k – to mop up sales from the Porsche 911 and Audi R8. But McLaren decided they should get the P1 out before the P13 so they could give their dealer network a nice halo model, and go head-to-head with LaFerrari and the Porsche 918 Spyder.

2013 Kia Sorento: UK Price & Spec

The 2013 Kia Sorento – Kia’s take on the Hyundai Santa Fe – arrives in UK showrooms this month priced from £26,495. Kia’s new Sorento is basically the same convincing package as the new Santa Fe, just wrapped up in a Kia instead of a Hyundai. That means new underpinnings and a more appealing shape with a tweaked and fettled 2.2 litre CRD under the bonnet attached to either a six-speed manual or 6-speed auto.

Chevrolet Spark EV tops EPA's fuel-economy rankings for 2014

The 2014 Chevrolet Spark EV has been named the most fuel-efficient vehicle by the EPA and the Department of Energy in a new ranking for 2014. The Spark EV returns a combined 119 mpg equivalent, achieving 128 mpg in the city and 109 mpg on the highway. Chevrolet's pure-electric hatch displaced last year's chart topper, the Scion 2013 iQ EV, with its 121 mpg equivalent rating, but the Scion is not offered for the 2014 model year, so it didn't make the list for the U.S.
