Porsche to unleash latest powerhouse
Porsche is unleashing a new, more powerful version of its 911 GT3 RS this July.
The company is only making 600 worldwide.
The flat engine's crankshaft is straight from the 911 GT3 RSR racing car’s six-cylinder engine.
The four-litre, the biggest in a 911, is claimed to be most powerful naturally aspirated engine.
This pumps out 500bhp and sprints from a standing start to 100kmh in just 3.9 seconds.
