Delphi Corp.’s virtually standard diesel fuel injection system and powertrain cooling technology as used in many popular road cars helped power two Peugeot RCZs to an impressive first and third in-class standing at the gruelling ADAC 24-hour endurance race at the Nurburgring (May 15?16). Competing against 197 vehicles, including many highly modified for racing, the RCZ 2.0 liter HDi diesel coupés delivered extraordinary speed and endurance in the hands of ‘gentleman drivers’ from France and Germany. To demonstrate the reserves of performance and durability inherent in the regular production vehicles, Peugeot raced cars that were largely unmodified from the road-going versions that have just been launched to celebrate the company’s 200th anniversary.
The two RCZs ran in the D1T category for diesel cars between 1.7 liters and 2.0 liters. The key change to the standard engine is an increase in turbo boost pressure, lifting the torque from 340Nm to 400Nm and the power from 120kW to 150kW. Even with this extra boost, Peugeot used production Delphi charge air coolers and radiators supplied to the road cars as they met the performance targets required for endurance racing.
