FIVE REASONS THE B6.7 IS THE BEST ENGINE IN ITS CLASS

Every aspect of the B6.7 has been engineered for reliability, durability and fuel efficiency to deliver the lowest cost of ownership with maximum uptime.

1. THE PROVEN CHAMPION

  • Over 33 years of global production and experience, with over 600,000 B-Series engines produced every year
  • A long history of industry innovation and reliability, tested and proven across the harshest environments and extreme applications

2. BEST-IN-CLASS DURABILITY

  • When both engines are producing the same amount of power, pressure exerted on each piston during the power stroke is spread across 6 cylinders (B6.7) vs. 4 cylinders (DD5).  This results in a lower BMEP (Brake Mean Effective Pressure) rating, or less average pressure exerted on the piston during each power stroke.
  • Less stress per cylinder reduces the overall stress on the engine and increases engine life

3. NO REPLACEMENT FOR DISPLACEMENT

  • Larger displacement engines are capable of producing higher torque at lower rpms
  • Higher torque means smoother performance and an ability to handle greater loads
  • Inline 6 cylinder engines are naturally balanced producing less noise, vibration and harshness for improved driver comfort

4. LESS COMPLEX, MORE RELIABLE

  • The B6.7 uses a proven and simple Cummins Variable Geometry Turbocharger (VGT) that delivers superior performance under all operating conditions
  • A two-stage turbocharger solution is complex, heavier and more difficult to service

5. UNMATCHED SUPPORT

  • The B6.7 features the largest service network in the industry with over 3,500 service locations in the US and Canada
  • With over 12 million B-Series engines produced globally, the B6.7 has the largest network of trained and certified technicians in the world
  • Well established distribution centers ensure parts are widely stocked for best-in-class availability
