So it looks like it will be official, Porsche AG is looking to debut the 2013 Porsche 991 Turbo at the Frankfurt Motor Show in September 2013. There’s a lot of speculation around this supercar, however it’s safe to say that the turbocharged engine will be a 3.8 liter six cylinder, boxer layout (that means the cylinders are horizontally opposed to each other). Power will be applied to an all wheel drive system with a max output in at 530 hp – slightly more than the outgoing Porsche 997 Turbo S.
Featuring four turbochargers, two intercoolers, four adjustable camshafts, a complex multistage intake manifold, and dual-stage exhaust, the 3.9-liter engine is expected to deliver 650 hp and shoot the machine from a standstill to 100 km/h in an estimated 2.5 seconds.
We got a few owner-experts and one semi-professional driver to test out a stock 2007 Porsche Turbo, another equipped with after market Bilstein coilovers (and other goodies), a 2008 GT2, and 2010 Porsche GT3. Switching back and forth between all four cars for about 3-4 hours in twisty canyon roads – we all reached some interesting conclusions.
