Courage C41
The Courage C41 was a sports prototype racing car built by Courage Compétition in 1994, and used in international sports car races from 1995 until 1999. Designed by Paolo Catone, it initially used a 5-litre Chevrolet V8 engine, developed by Comptech, and later used the 3-litre twin-turbocharged flat-six engine from a Porsche 935, as well as an Oldsmobile V8. In 1998, two of the C41s were developed into the Courage C51, which used a 3-litre twin-turbocharged Nissan VRH35Z V8 engine, and was used in that year's 24 Hours of Le Mans. In 1999, the C41s were mostly converted to the C52 specification (although one retained its Porsche 935 flat six, and was developed into the C50, whilst another was entered as a Chevrolet-entered C41 in two events); this initially used a 3.5-litre twin-turbocharged Nissan VRH35L V8, which was then replaced by a 3.2-litre twin-turbocharged Peugeot A32 V6 engine for 2000. In 2000, the C41 line was replaced by the new C60.
==Design and development==
In 1994, Yves Courage decided to build a World Sports Car for the IMSA GT Championship, which was the Paolo Catone-designed C41. Although the C41 was entirely designed by Catone, Marcel Hubert had initially developed a long-tailed concept model for the car, but this design was scrapped after Hubert retired.〔 Catone began to design the car, on a limited budget, in early 1994, and completed it in July 1994.〔 The C41 used a carbon fibre and aluminium honeycomb monocoque chassis, with a rear shear plate designed to allow the usage of multiple different types of engine.〔 The first C41 was built in October 1994, and it was fitted with a Comptech-developed 5-litre Chevrolet V8 engine, which, in 1995 24 Hours of Le Mans trim, was claimed to produce around .〔 The power was transmitted to the rear wheels via a 5-speed Intermotion SDC gearbox, whilst Brembo brakes were used to slow the BBS wheels.〔 KONI developed the suspension, which consisted of double wishbones made out of fabricated steel, and pushrod-operated dampers with coil springs.〔
The Chevrolet engine remained the primary engine for the 1995 and the start of the 1996 IMSA GT Championship seasons, but by the middle of 1996, different engines began to be fitted.〔(【引用サイトリンク】title=Complete Archive of Courage C41 )〕 Scott Schubot fitted an Oldsmobile engine to his C41 partway through the 1996 season, whilst a 3-litre twin-turbocharged Porsche 935 flat-six engine was fitted by Courage for the 1997 24 Hours of Le Mans.〔
In 1998, two C41s were developed into the C51 specification for that year's 24 Hours of Le Mans; one of the C51s used a 3-litre twin-turbocharged Nissan VRH35Z V8 engine derived from a Nissan Group C car, whilst the other used a 3.5-litre version of the same engine.〔(【引用サイトリンク】title=Courage Compétition career owner statistics )〕 The C51 was then further developed into the C52 for the 1999 24 Hours of Le Mans,〔 and the VRH35Z was replaced with a 3.5-litre Nissan VRH35L engine.〔(【引用サイトリンク】title=Complete Archive of Courage C52 )〕 For this race, another C41 was converted to the C51 specification, although this retained its Porsche 935 flat-six;〔 this C51 is also referred to as the C50.〔(【引用サイトリンク】title=Complete Archive of Courage C50 )〕〔(【引用サイトリンク】title=Pescarolo Sport career owner statistics )〕 The final development of the C41 line came in 2000, when the C52s were fitted with the Sodemo-developed 3.2-litre twin-turbocharged Peugeot A32 V6 engine, producing a claimed output of .〔(【引用サイトリンク】title=Courage C52-Peugeot (2000) )〕 In 2000, the new Courage C60 was introduced as the C52's replacement, bringing to an end the C41 line.
