The 1989 Mercedes-Benz #63 Sauber-Mercedes C 9 - abbreviated as "#63 M-B C 9" - is a prototype race car by Mercedes-Benz.
It appears in Forza Motorsport 4 as part of the August Playseat Car Pack. It returns in Forza Motorsport 7 and Forza Motorsport (2023).
The Sauber C 9 is a Group C prototype race car introduced in 1987 as a replacement for the previous Sauber C 8 and a continuation of the partnership between Sauber as a constructor and Mercedes-Benz as an engine builder for the World Sportscar Championship.
Characteristics[]
The Sauber C 9 is a development of the C 8, retaining a largely aluminum monocoque but with considerably higher stiffness and numerous other improvements. The rear suspension changed from vertically positioned spring/damper units arranged over the top of the gearbox to a horizontal layout aligned with the longitudinal axis of the car.
Aerodynamic changes include the repositioning of the combination of oil/water radiator to the nose of the car, which allowed the use of a modified splitter plate, the removal of the large NACA ducts from the top of the door sills, a re-profiled rear deck, and a rear wing now mounted solely on a central support. There are two aerodynamic configurations for the car: one for sprint circuits and a low drag version for the 3.6 mi (5.79 km) Mulsanne Straight at Le Mans. In its sprint configuration, the C 9 produces 4899 lb (2222 kg) of downforce at 200 mph (322 km/h) with 1225 lb (556 kg) of drag, 3968 lb (1800 kg) of downforce at 180 mph (290 km/h) with 992 lb (450 kg) of drag, and 2756 lb (1250 kg) of downforce at 150 mph (241 km/h) with 689 lb (313 kg) of drag.[1]
The C 9 is powered by a 5.0L (4,973 cc) twin-turbocharged, mid-mounted M119 V8, with 17.6 psi (1.2 bar) of boost producing up to 750 hp (559 kW) and 597 ft·lb (810 N·m). The C 9 revs up to 7,000 rpm, although drivers generally stayed up to 6,500 rpm during races. The torque curve in the 3,000 to 6,000 rpm range is almost uniform, giving plenty of engine flexibility. With a weight of 1995 lb (905 kg), the C 9 has a power-to-weight ratio of 829 hp (618 kW) per tonne.[2]
The C 9 is capable of accelerating from 0 - 60 mph (97 km/h) in 2.7 seconds, 0 - 100 mph (161 km/h) in 4.9 seconds (5.5 seconds in Forza Motorsport 4), and a top speed of 248 mph (400 km/h), which only the Forza Motorsport 4 rendition of the car can reach, as the Forza Motorsport 7 rendition is instead limited to 228 mph (367 km/h).

Performance[]
The Sauber-Mercedes C 9 is a car that is well balanced in all performance aspects, with very fast acceleration including the ability to reach 100 mph (161 km/h) in less than 5 seconds, extremely sharp handling even at high speeds, very efficient braking that allows it to continue longer into a corner and still be able to brake to appropriate cornering speeds quickly, and a sufficiently high top speed for all tracks. One disadvantage of the C 9, though, is the moderate to strong wheelspin it experiences off the line, thus making this car recommended for advanced drivers. In Forza Motorsport 4, the C 9 is the top-ranking car in X Class one-mile drag races, on oval circuits, and in the Bernese Alps due to said performance traits.
Trivia[]
- The #63 M-B C 9 has 800 hp (597 kW) and 600 ft·lb (813 N·m) in Forza Motorsport 4.
