Porsche has recently revealed a handful of new details on the upcoming production version of the 918, which it published in its own in-house magazine, Christophorus.
Porsche says it will use a modified version of the new LMP MR6 4.6 liter V8 engine adapted for use in the production 918. Initially, the 918 concept featured a 3.4 liter gas engine, and has increased the displacement to 4.6 liters.
Only a few details of the new engine have been revealed, however to quote: “The 918 Spyder V8 will feature a central injector mounted directly adjacent to the spark plug, a central oil feed to the crankshaft, a variable-pressure composite oil pump and scavenge pump, forged lightweight pistons from a Formula 1 supplier, a very high compression ratio, and variable valve timing with intake and exhaust phase stepper motors.”
It’s no surprise that power figures for the new engine have not been announced, although reports point to around 550HP from the V8, along with the hybrid’s electric motors that should add a further 225HP.
The production 918 Spyder supercar is planned to makes its debut at the 2013 Frankfurt Motor Show.
