Ruf RGT-8 based on the 2012 Porsche 911 (991)

Article by Christian A., on March 12, 2012

The latest RGT-8 from Ruf is based on the 991 generation of the Porsche 911. The company founded by the late Alois Ruf has an expert engineering staff and a business prowess that had has made it even more popular. This latest RGT-8 continues to substitute a 4.5-liter V-8 for the Porsche’s standard flat-six.

This is the same treatment applied by the 997-gen 911 to the RGT-8. Ruf is known for its tidy installations that are also designed well. The 991 911 has an enviable output, using naturally aspirated sixes that deliver up to 400 hp and 325 lb-ft of torque. The Ruf V-8 raises its power to 543 hp at 8500 rpm and 369 lb-ft at 4000 rpm.

Its engine is a Ruf design and is exclusively built for the Bavaria-based firm. Its 32-valve design has an aluminum block and aluminum heads, integrating DOHC, a flat crank, and dry-sump lubrication.

Its engineering was supervised by Hans Mezger, who developed the engine for Porsche’s powerful 917 race cars. This conversion doesn’t come cheap at around €200,000 (slightly higher than $263,000) at the present exchange rates. If 543hp still doesn’t satisfy you, you could ask Ruf for more through turbocharging. The target for this enhanced V-8 is 900 hp.

Even with all the years behind it, the latest 911 Carrera to come out from Porsche is revealing itself to have one of the largest changes when it comes to development. Proof is that about 90% of all its parts have either been redeveloped or redesigned. Changes include the body making use of lightweight materials and improving the efficiency of the drivetrain.

Even a new suspension has been equipped inside. In addition, the new generation of the 911 Carrera also comes with the enhanced version of the Porsche Intelligent Performance. This is seen not just in the driving dynamics that are now better but in the daily practicality and the fuel consumption and emissions being reduced by as much as 16%.

That Porsche has redesigned the 911 Carrera can be seen no matter where it is looked at. On the side for instance, one can observe the alloy wheels with its new style and larger size. Since the windscreen now has a more convex shape, it gives the 911 Carrera a livelier look with a quality similar to a coupe. Aside from being redesigned, the front section is now wider and has been fitted with larger side air intakes and new headlights.

In developing the 911 Carrera, the brand made sure that the proportions and the design would complement the technology inside. One result of this is that the wheelbase is now longer by 3.94 inches (100 mm). Even then, the overall length has been increased by a mere 2.20 inches (56 mm). These could be because the overhangs were all shortened with the front cut by 1.26 inches (32 mm) and the rear reduced by 0.47 inch (12 mm).

In terms of overall length, the 911 Carrera measures 176.81 inches (4,500 mm) with a width of 71.18 inches (1,800 mm). This makes the latest 911 Carrera the most compact vehicle in its segment.

When compared to the previous generation, the new 911 Carrera has a roof line that is lower by 0.28 inch (7 mm). It is even lower by 0.24 inch (6 mm) compared to the Carrera S. Despite this, the maximum headroom is still the same. Models that have a sunroof fitted to them will experience an increase in the headroom 0.59 inch (15 mm). This sunroof in addition is the first of its kind to have an electric slide/tilt.
