The RUF Rt 12 S is a rear-engined, Porsche 911 (997)-based supercar that is a higher-end version of the RUF Rt 12.
The RUF Rt 12 S, based on the Porsche 911 Turbo S (997), is a rear-engined supercar that is powered by a 3.6L (3,600 cc) twin-turbocharged boxer-6 Porsche M96/70S engine. The engine produces 676 hp (504 kW) and 649 ft·lb (880 N·m) of torque. The RUF Rt 12 S has its engine placed in the rear and has its power delivered to the rear wheels via a six-speed manual transmission.
The Rt 12 S has a RUF-designed rollcage integrated in the ceiling as standard. On the front of the car, there are separate LED alternative lights for the position light and turn signals. At the rear, a carbon rear wing with air ducts which are integrated into the widened rear fenders complete the Rt 12 S's appearance, along with exterior mirrors from the RUF CTR 3.
The Rt 12 S has forged 19 inch light alloy wheels in the front and in the rear. Behind them, it is possible to see the ceramic brake discs of this high performance brake system. The chassis and the aerodynamics are tuned to a maximum speed of 224 mph (360 km/h). Optionally, RUF can deliver a height adjustable front axle which hydraulically offers 50 mm more chassis clearance by pushing a button for passing basement garages and higher curbs easily.
The RUF RT 12 S is the only Tier 7 vehicle available by default. It has a higher top speed than the Ferrari 288 GTO and Lamborghini Aventador LP 700-4, but suffers from weak nitro, as it has the same nitro power as the Aventador. However, it has the better efficiency as its competitor, at 1.30% versus 1.20%.
The RUF Rt 12 S, with its name now shown in all caps, is the highest-ranking original Class A car, with a starting rank of 1500, a MAX rank of 1608, and a MAX+PRO rank of 1679. The car receives a small +25 from Tuning Kits.
The RUF RT 12 S, unlike the Lamborghini Sesto Elemento, is a more top speed-focused car; while having decent handling and drifting, the RT 12 S has the edge in top speed only. Because of its low nitro stat, it has nitro efficiency rated at 10/15/20, meaning the RT 12 S is a car that works best on short tracks, although it isn't the slowest Porsche-based car in the game.
The RUF RT 12 S cost 275,000 to purchase, 364,400 to max out, and 225,146 for Pro Kits, which also require 6 of each Class A Parts card, 8 F6 Engine cards, 2 Initial Tech cards, 2 Early Tech cards, 12 Mid-Tech cards, and 4 Advanced Tech cards. As of the Porsche Update, it is no longer available for purchase. Prior to the aforementioned update, the RT 12 S and all other Porsche-derived cars were given away via giveaway cups.
In summary, the RUF RT 12 S, while not recommended as a go-to car, is far from the worst car in the game, as it can be used for RUF-only events and is required for completion of the regular Career Mode. It also counts towards a few collections, namely "German Steel" and "Euro Aces". In Multiplayer, though, it is not recommended to use the RT 12 S due to its restrictive performance, unless the player is required to use a RUF car for Multiplayer for the favour of Daily Tasks; in this case, should the player wish to complete such a task, the player has to do so in a free race.
The RUF RT 12 S appears as a Tier 4 car. It costs 950 gold, making this car the only gold-based car in its tier. It is also a prerequisite for the last restriction race of its tier. The RT 12 S is higher-ranked than the Ferrari 458 Italia.
