NRR Advantages Over Ford F-550

Ford F550

NPR 3500

Ford F-550:

  • F-550 competes against NQR and NRR
  • 4 wheelbase choices on F-550 regular cab with 120 inch maximum CA
  • 17,950 lb. is the base GVWR for F-550. 19,500 lb.
  • GVWR is available only with the diesel engine F-550
  • 6.8L V-10 gas standard with 17,950 lb. GVWR only
  • 6.4L diesel engine available and required with 19,500lb. GVWR
  • Available with regular cab, extended cab or crew cab
  • New Ford Work Solutions connectivity features
  • 4WD available
  • No tilt cab -- difficult engine accessibility

NRR Advantages:

  • Overall length of comparable CA trucks is 50 inches shorter for Isuzu, requiring less parking space for fleets
  • Maximum CA of 189.5 in. for Isuzu vs. 120 in. CA for F-Series. N-Series can accommodate bodies to 24 ft. in length vs a maximum 16 ft. on F-Series
  • Built from the ground up as a commercial vehicle for a long life (F-550 is derived from a pickup)
  • Reverse Elliot I-Beam front axle and taperleaf springs on
  • NRR are rugged and low maintenance with excellent service history. Ford uses coil springs on a tubular beam, with leading links and a lateral link for axle location.
  • Conventional cab Ford weights much more than shorter cabover Isuzu. Comparable CA diesel models show Isuzu is more than 2000 lb. lighter than Ford. Extra truck weight costs operators extra fuel for every mile traveled.
  • Isuzu has one-ton higher payload than GVWR Ford
  • Tilt cab allows easy engine access (limited engine access on F-550 Super Duty with very high reach-over to engine area)
  • Tighter turning diameter (curb-to-curb) for comparable cab-to-axle ratio (33.5 ft./109.0 in. WB vs. 48.6 ft./165.0 in. WB ) dramatically improves maneuverability
  • Wider door opening for easy entry and exit (85 degree vs. 60 degree)
  • Durable tricot breathable woven seat material is comfortable and long lasting (solid vinyl standard on F-550 Super Duty)
  • Standard tilt and telescopic steering column contributes to driver comfort (optional tilt steering wheel on F-550)
  • Grab handle to assist entry and exit contributes to safety on the job (not available on F-Series)
  • 6-speed automatic vs. 5-speed helps improve performance and efficiency
  • Standard fold-down center seat includes convenient work area on NPR; base seat on F-550 is non-folding bench
  • Higher frame yield strength contributes to durability (44,000 psi vs. 36,000 psi)
  • Standard diesel exhaust brake contributes to brake life and braking performance. Not available on F-550
  • Greater visibility with larger windshield, larger side windows, larger side mirrors and lower dash to improve vision. Front sight line of 8.6 ft. for NPR vs. 23.8 ft. for F-550
  • Wide, self-cleaning step on NRR vs. optional cab steps on F-550
  • Standard daytime running lamps vs. optional
  • Battery box on frame rails of NRR helps extend battery life by removing batteries from hot under-hood area
    50-state clean idle certification on Isuzu vs. timed idle shut-down after 5 minutes on F-550
  • Easier serviceability with in-cab fluid checks vs. Ford's under-hood fluid-checks
  • Available limited slip differential provides low-traction solution that's less expensive than Ford's 4WD and better performing than Ford's optional traction control
  • Available Vehicle Health Reports allows Isuzu fleet to monitor drivers and vehicle service needs. Not available on Ford
