Isuzu introduced a multitude of changes for 2005-2006, including new features inside and a new look on the outside for the '06 N-Series. The flush-mounted headlamps, cornering lamps and turn signal are perhaps the most eye-catching change, followed by a new composite bumper.
Inside, drivers can expect to find lighter colors and a new, breathable cloth seat material. A tachometer has been added, as well, to aid Power Take Off (PTO) operation and a new rear steel engine cover is designed to improve back-of-cab appearance and help retain heat during cold weather operation.
All new N-Series models (Class 3 NPR, Class 4 NPR HD and Class 5 NQR and NRR) also feature standard power door locks for '06, a new engine control module mounting bracket for improved body mounting, plus a Donaldson polypropylene air cleaner (for the diesel single cab) for easier serviceability and more corrosion resistance, according to Isuzu‥
Power options have likewise been expanded. An NPR diesel model with a 12,000-lb. GVW rating certified in all 50 states is available for '06, extending the diesel-power availability to five GVW ratings: 12,000-, 14,500-, 17,950- and 19,500-lb.
The 5.2L Isuzu 4HK1-TC turbocharged, intercooled diesel engine produces 190 horsepower and 387 lb.-ft. of torque, and can be paired with a 6-sp. manual transmission or with the Aisin 450-43LE 4-sp. automatic.
The gasoline-powered Vortec 6000, 6.0L V-8 engine can also be spec'd for the NPR and NPR HD models. It delivers 300 horsepower and 358 lb.-ft. of torque driven through a Hydra-Matic 4L80-E 4-sp. automatic Warranties for '06 N-Series vehicles have been extended to 36 mo./unlimited mileage.
Isuzu also introduced a series of conventional trucks for '05, dubbed the H-Series and available in Class 6 (HTR, 25,950 lb.), Class 7 (HVR, 25,950-33,000 lb.) and Class 8 (HXR, 33,000-54,600 lb.) weight ratings.
All H-Series feature the Isuzu 6HK1-TC 6-cyl. diesel engine, with horsepower ratings from 200 to 300 and torque output from 520 to 860 lb.-ft., driven through an Allison 2400 or 2500 series (2500 is standard on HTR and HVR) or Allison 3000 or 3500 series (HVR and HXR only). The Allison 3000 is standard on the HXR. Manual transmission fans can also chose either the Eaton 6-sp. (HTR and HVR) or the Eaton 9/10-sp. manual (HXR).
Cab options include the regular three-person cab (105-in. BBC) or a six-person crew cab (146-in. BBC). Driver and passengers have a variety of seating options, including air seats and a two-person passenger seat that features a fold-down work surface and integrated storage.
2005 H-Series models are available as Right-Specs with pre-engineered specs for chassis to be up-fitted as vans, stake trucks, dump trucks, utility trucks and refrigerated bodies.
Low-cab-forward F-Series models will continue to be available in a wide range of configurations for 2005-06, including as Right-Specs for expedited delivery with pre-engineered specifications. The F-Series is available in Class 6-8 GVWR with wheelbases from 128- to 260 in. and is powered by the Isuzu 6HK1-TC inline, 6-cyl. diesel.
20th anniversary edition: Red Rider
A limited number of special edition trucks, painted cardinal red and featuring 14×18-ft. hardwood floors, 42-in.-high side stakes and stainless steel wheel covers, will be available through Isuzu dealerships in the early spring of 2005. Called Red Rider, this commemorative chassis was inspired by the famous red-colored wagons beloved by children for decades.
