This lime green Porsche 911 RGT-8 was unveiled at the Geneva Motor Show from the RUF car tuning specialists. Looking like a solid build, the most suprising thing about this project is that it doesn’t use a Porsche engine! Instead, the tuners modified an in-house 4.5-liter V8 powerplant to produce some impressive numbers. With this innovative design, and compact engine, the Porsche 911 power increase shows 550 hp at 8,500 rpm, and 500 Nm of torque at 5,400 rpm. RUF was able to shave off 200 kg with the customizations under the hood, and even gave the race car a dry-sump lubrication system which is effective under all driving conditions.
