There are tuner shops, and then there are tuner manufacturers. What’s the difference? While a Tuner shop will bolt on spoilers and body kits, and some good tuner shops can even enhance your engines performance; a tuner manufacturer takes a bare shell and makes the entire car themselves to meet their customer’s requirements.

That is exactly what Ruf does. For 34 years, Alois Ruf has been working on Porsches. His process is so thorough, Porsche sends him bare shells of their cars, and everything is then put in place by Ruf technicians. Each car is thus tailor made for its new owner.

While most of Ruf’s creations look like slightly modded versions of the Stuttgart original, in 2007 they unveiled a car that took the tuning game on a whole new level. It was called the CTR3 and it was built using a chassis that had bits of the 911 married to some Cayman structure, wrapped in a Kevlar-carbon composite body-shell. The end result looked like a car Porsche enthusiasts could only dream about, until now.

It’s not all about looks either. Under the rear clamshell you’ll find a 3.8-liter, flat-six engine with two turbo-chargers. Twin-turbo Porsche motors are not that uncommon, but ones that produce 750-hp and 708 lb/ft of torque certainly are. All this power is fed to only the rear wheels via a six-speed sequential gearbox. Launch it correctly and you’ll cover the sprint from 0-60 mph in just 3.2 seconds, and onto a top speed of 236 mph. That makes the CTR3 a lot faster than the Carrera GT, the fastest production car Porsche ever made.

If all this sounds irresistible to you (if you’re reading about cars on the internet, it should), you’d be happy to learn that a CTR3 is currently being offered for sale in California by R3 Motorsports. Since their advert was missing some information, we called the owner of the company; Ryan Negry, for some more information on this rare beast. According to Negry, this 2010 example has covered just 300-miles and that it can be yours for just $540,000.

Infamous Porsche tuner RUF has unveiled their third generation CTR, the Cayman-based supercar featuring a mid-engine design with a 3.8L flat-six with 750-hp and 708 lb-ft of torque. RUF’s CTR variants have always been known to be in a league of their own, and the CTR 3 is no exception, featuring a Kevlar-carbon body shell, with a hood and a pair of doors made from lightweight aluminum.

The car itself has been transformed to support the new mid-engine design with galvanized steel used for the front structure and passenger compartment. The powertrain has been fixed in a space frame and modular tubular frame construction. Inside, the passenger compartment is reinforced with RUF’s Integrated Roll Cage.

Engine-wise, the twin-turbocharged powerplant features a pair of intercoolers – one for each turbo – placed in front of each rear wheel. Mated to the 3.8L flat-six is a transversely mounted sequential 6-speed transmission with a limited slip differential.

The CTR 3 also features a staggered set of 19-inch wheels in the front and 20-inch wheels in the rear, with the widebody fitting 335/30/20 tires in the back. Those interested in purchasing a CTR 3 can also have the interior customized to their liking with leather and Alcantara options.

All said and done, the CTR 3 weighs in at 3,086-lbs and with 750-hp, it has a power-to-weight ratio of 4.4-lbs per hp. That makes for a 0-62 mph time of just 3.2 seconds and a top speed of 236-mph.
