  1. MAZDASPEED Protégé Development

  2. Program Goals • Identify, define, analyze and evaluate engine and vehicle system modifications that represent a commercially significant improvement in the rated performance of the Mazda MP3.

  3. Process • Phase I: Baseline Performance Validation • Phase II: Performance Development • Phase III: Emissions and Durability Validation • Phase IV: Production

  4. Phase I Baseline MP3 Engine Dyno: 122.7 bhp (SAE) Engine Dyno: 126.8 lb•ft Tq (SAE) Chassis Dyno: 105.5 bhp (SAE) Chassis Dyno: 111.4 lb•ft Tq (SAE) 0-60 mph: 8.41 sec. 50-80 mph: 8.77 sec 1/4 Mile ET: 16.48 sec. @ 84.6 mph

  5. Benchmarking

  6. Performance Targets • 170 Horsepower - SAE @ Engine • 160 lb•ft Torque - SAE @ Engine • Peak Cylinder Pressure <= 73 kg cm2 • 7.2 seconds 0 - 60 mph Acceleration • 15.6 seconds 1/4 mile elapsed time @ 90 mph

  7. Solution • Inter-cooled Turbocharger system, integrated into existing vehicle package.
