What Does NNBS Silverado Mean? Differences Between OBS vs NBS vs NNBS
The updated Chevy Silverado includes a luxurious and comfortable interior, a powerful engine, slick handling, and several cutting-edge technologies and safety features. The Silverado’s average rating has less to do with its own shortcomings and more to do with the advantages of its main competitors.
It could be intimidating for a new consumer to surf the sea because the vehicle has been manufactured for a very long period. Particularly when used as the “NNBS” model.
Now, I’ll be explaining What NNBS Silverado means and everything in between in this post.

What Does NNBS Silverado Mean?
The term NNBS has been in since 2007 when the second generation of Silverado came out. ‘NNBS’ means New New Body Style. It points to trucks produced from 2007 to 2013.
It had been given a new body, interior, structure, and suspension, and some of the engines had more power. It borrowed design influences from the Chevrolet Colorado trucks and 2007 GMT900 SUVs.
The GMT800 hybrid series was discontinued in 2007, therefore a two-mode hybrid variant was unveiled in late 2008 as a 2009 model. Due to weak sales, General Motors stopped producing the Silverado Hybrid.
OBS vs NBS vs NNBS
The three distinct generations of Chevy Silverado pickups are sometimes referred to by the acronyms “OBS,” “NBS,” and “NNBS.” “Original Body Style” refers to Silverado vehicles produced between 1989 and 1998.
The term “NBS” refers to Silverado pickup vehicles produced between 1999 and 2007. While NNBS began to be produced in 2007.
1. OBS
OBS stands for old body style. These are one of the first models produced in the production line. When the Silverado moniker debuted for the 1975 model year, it replaced Custom Deluxe, Scottsdale, and Cheyenne as the highest trim level on all Chevrolet C/K trucks.
Chevrolet maintained the C/K model name for the 1988 GMT400 model architecture, whereas GMC branded its full-size range as Sierras.
Despite having similar chassis and bodywork, the Silverado and Sierra have separate model trajectories, with the Sierra having five generations and the Silverado having four.
2. NBS
The New Body Style Silverado trucks hit the road in 1999. GM started working with a number of teams to create the GMT800 pickup program in January 1993. Rather than starting in June 1998 as planned, a fresh design was chosen and approved for production in June 1995.
Late in 1997, development approval was given, and pre-production and series production started in June 1998.
The 1500 moniker is used for light-duty vehicles. They come in three cab lengths: a front-hinged 4-door crew cab, a 3- or 4-door extended cab, and a 2-door standard/regular cab.
The HD model was a heavy-duty light truck vehicle. It came in 1500HD, 2500HD, and 3500HD versions and was a reinforced version of the Silverado/Sierra light-duty.
3. NNBS
The brand-new Silverado/Sierra GMT900 generation made its debut as a 2007 model in the fourth quarter of 2006. It has a new external, interior, structure, and suspension design, and certain engines have more power.
It borrows aesthetic elements from the Chevrolet Colorado trucks and 2007 GMT900 SUVs. These trucks, like the GMT900 SUVs, feature much better aerodynamics than their predecessors, such as sharply slanted windshields and fewer panel gaps, which increase fuel efficiency.
The redesigned Silverado won the 2007 North American Truck of the Year award and was named the year’s best truck by Motor Trend magazine.
Newer Generations
Third Generations
Three gas engines are available for the third-generation Silverado 1500: a 4.3 L EcoTec3 V6, a 5.3 L EcoTec3 V8, or a 6.2 L EcoTec3 V8. The majority of vehicles will come with Chevrolet’s MyLink touch-screen multimedia interface technology.
In order to reduce bulk, the third-generation Silverado employs aluminum for the hood, engine block, and control arms. To save weight and increase strength, the truck’s bed is built of roll-formed steel rather than the stamped steel used by other producers.
Underneath, the Silverado is supported by a completely boxed, hydroformed high-strength steel frame; the truck cab’s structure is also made of high-strength steel.
Fourth Generations
At the Chevy Truck Centennial Celebration in 2017, Chevrolet debuted the brand-new, fourth-generation 2019 Silverado 1500. The exterior of the Silverado 1500 is more contoured. There will be eight different trim levels for the Silverado 1500: WT, Custom, Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, and High Country.
A rearview backup camera system, power windows, and door locks, air conditioning, a next-generation touchscreen infotainment system with Apple CarPlay and Android Auto, Bluetooth for hands-free calling and wireless audio streaming via A2DP, and a next-generation touchscreen infotainment system are all included in all trim levels.
GPS navigation, SiriusXM Satellite Radio, Travel Link, OnStar with 4G LTE in-vehicle Wi-Fi, a Bose premium audio system with seven speakers, keyless entry, push-button start, and other amenities are additional options that are available on specific trim levels.
Special Editions
1. Intimidator SS
In 2006, Chevrolet unveiled the “Intimidator SS,” a special edition Silverado SS to pay tribute to the late Dale Earnhardt. The vehicle arrived with a number of little aesthetic changes.
2. Vortec High Output/Vortec Max
The LQ9 6.0 L V-8 engine was one of several options added in this special edition package (under option number B4V) that were previously unavailable on the basic 1500 model.
3. Rally and Midnight Special Editions
After being gone for the 2019 model year, the Rally and Midnight Special Editions are back for 2020. Available trims for the Silverado Custom and RST include Rally Edition. The package includes black assist steps, black CHEVROLET tailgate lettering, and black Rally Stripes on the hood and tailgate.
