  1. 2008 Corvette Powertrain

  2. Powertrain Lineup • 6.2L V8 (6162 cc) • 430 hp @ 5900 rpm (SAE certified) • 436 hp @ 5900 rpm w/ optional exhaust (SAE certified) • Hydra-Matic 6L80 six speed automatic • Tremec six-speed manual (w/two optional gear ratios)

  3. Powertrain Engine Improvements – Piston / Rods • Larger flat top piston design @ 10.7:1 compression ratio • Addition of 4 drilled piston oil drainback holes and higher oil control ring tension to improve the high speed operation at higher performance • Piston profile and pin bore optimization for NVH • Tapered pin ID for mass reduction • Rod bolt joint enhancements include new 12.9 grade rod bolts - similar material as LS7

  4. Powertrain Engine Improvements – Valvetrain Gen III/IV conventional rocker arm • Valvetrain • Intake valve diameter increased to 55 mm vs. LS2 50.8 mm • Hollow intake valve for mass reduction to maintain high speed operation and the 6600 rpm redline • New inlet rocker arm offset by 6mm between valve tip and rocker bolt/ pushrod to enable an improved airflow path High flow head offset inlet rocker arm

  5. Intake Port Flow Results

  6. Exhaust Port Flow Results

  7. LS2 vs. LS3* Power and Torque *SAE Certified

  8. Powertrain Transmission – Hydra-Matic 6L80 • Six speed, rear mount, automatic transmission • Driver shift control • Clutch-to-clutch • The LS3 with the 6-speed paddle shift automatic is the fastest automatic Corvette ever with 0-60 mph in 4.3 seconds.

  9. Powertrain Transmission – Tremec six speed manual
