In 2010, an updated version of the 997 RGT, was unveiled at the Geneva Motor Show. The car was powered by a completely new, Ruf designed 4.5-litre V8 engine with a 180° flat-plane crankshaft. It features four valves arranged spherically together with multipoint fuel injection which ensure optimal mixture conditions while the dry sump oil system supplies the necessary lubrication." Ruf made the RGT-8 as light as possible by installing the aluminum doors, an aluminum hood, a carbon fibre engine cover, and a carbon fibre rear spoiler. Like the flat-6 versions, the new RGT-8 also includes ceramic brakes, an integrated roll-cage, and 19-inch forged alloy wheels with Michelin Pilot Sport Cup tires.


When the Porsche 997 debuted, Ruf bored out the 3.6 L engine to 3.8 litres (231.9 cu in), modified the exhaust and catalytic converters, and replaced the ECU and air filter. The new power output was 445 bhp (332 kW), reducing the 0-60 mph (97 km/h) time from 4.6 to 4.2 seconds (or even 4.1, according to some sources),[citation needed] and increasing top speed by 7 mph to 317 km/h (197 mph).

Ruf also added a performance suspension system, using Bilstein components, as well as high-performance Brembo disc brakes, measuring 13.8 in (351 mm) in front and 13 in (330 mm) in the rear.

The car's appearance is also changed, using a bodykit that includes a polyurethane front air dam and carbon fibre doors, mirrors, engine lid, and spoiler, all of which reduce the car's weight to 2,932 lb (1,330 kg). The car is fitted with 19 inch Ruf-designed Superleggera wheels and Michelin Pilot Sport Cup tires. Finally, the RGT is customized with interior trim of the customer's choice, including Recaro seats and the deletion of unnecessary parts to save weight.

"RUF is an incredible automaker in their own right—while it may seem easier to start with an existing chassis to create your model line, when you consider how much work goes into each RUF you quickly realize that this is not necessarily true. Creating a RUF is not easy; starting with modern Porsche body-in-whites (meaning, a bare welded-together chassis without VINs, sold to RUF), RUF does the rest of the assembly, fitting mostly bespoke components and re-engineering nearly everything else to craft an entire package engineered to work together from the get-go. First, there’s the integral rollcage that RUF installs in each chassis, a signature element that adds rigidity and safety—a tradition started with the CTR2 in 1996. After that, things get wilder. The RGT-8 is a good example: it doesn’t even feature a Porsche-based engine. Instead, RUF designed its own original V8—a 4.5-liter flat-plane crank masterpiece—from scratch in two years flat. The resulting engine is less than an inch longer than the 3.6-liter flat six found in a normal 911, and it’s a full 88 lbs. lighter. To make matters even more interesting, it produces about 550 horsepower without the aid of turbochargers or superchargers. Outside, the RUF is enhanced with special aerodynamic bodywork for a unique look, and RUF also fits upgraded suspension in several flavors. The RGT-8 is a fine example of what makes RUF special; completely redone from top to bottom, the result is a vaguely familiar shape with completely unique driving characteristics.
