A future Porsche 918 Spyder owner says the combined output of the powertrain will grow to 875 bhp (652 kW).
A TeamSpeed member (who also ordered the McLaren P1 and LaFerrari) says the combined output will rise from 795 bhp (593 kW) to 875 bhp (652 kW). This will be possible by uprating the V8 4.6-liter engine and we assume by tweaking the pair of electric motors.
He says the production version will look different than the concepts / pre-production models and most importantly, the car will be lighter than originally expected. The same source mentions it will be able to run the Nürburgring in less than seven minutes and drive on electric power for 150 km (93 miles).
Just like the 911 GT3, the new Porsche 918 Spyder will benefit from a four-wheel steering system, along with a targa top unlike its two competitors which have a fixed roof. Another member of the forum says Porsche will lose money with every 918 Spyder built and at the moment half of the cars have already been sold.
The production model will be reportedly shown in September at the Frankfurt Motor Show.
