Five least-green vehicles

We are a generation seemingly obsessed with the environment, eager to cover our carbon footprints in any way possible--or at least give off a green vibe visible to our neighbors).

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.
