With news that McLaren is plotting a Ferrari F12 and Lamborghini Aventador fighter in the shape of the P15, new details have come to light about the British supercar maker's other upcoming car - the P13. Previous reports revealed the sub-12C car would be powered by the same Ricardo-built 3.8-liter twin-turbo V8 that motivates the 12C, and that styling would be influenced by the P1.

Added to that is news from Autocar claiming McLaren is developing the entry-level car as a direct rival for the Porsche 911. Power will be in the region of 450-500 hp, which will be sent to the tarmac via a seven-speed dual clutch. 0-60 mph will be clocked in less than four seconds, and it will top out at 185 mph. McLaren has confirmed the model won't be called 'P13.' It will, however, be lighter and smaller than the 1,400 kg 12C with improved driving dynamics. The carmaker aims to shift around 4,000 units annually once all variants are out. These include a Spider and stripped-out, track-focused variant similar to the 911 GT3. A reveal is expected next year at the 2015 Geneva Motor Show.
