Decoding General Motors Body Style Designations

Earlier this year, GM Authority exclusively outlined how the GM C1 platform supports eight crossover utility vehicles, a circumstance that enables it to achieve massive economies of scale for the Detroit-based automaker.

With the prerequisites out of the way, there are three core pieces that make up the GM C1 platform body structure, as GM Authority learned from various GM engineers. When made at the body shop, this hunk of metal can end up in any of the eight crossovers currently riding on the C1 platform.

The second component goes between the B and C pillars. And finally, the third component starts from the C-pillar and runs toward the rear end of the vehicle. For instance, the GMC Acadia uses a different structure as it relates to this piece when compared to other three-row models such as the XT6, baby Enclave and three-row Blazer. Outside of these three core pieces of the structure, vehicles that ride on the GM C1 platform also share a significant amount of other common parts and components, including the electrical system, various systems controls, and HVAC componentry.

The C1 architecture is platform sharing done right, showing just how far the automaker has come from the badge engineering days horrors of yore.

Like these exclusive reports? GM Authority Founder with a passion for global automotive business strategy. I relies how this is great, for GM! As GM can make more of the same the cost of manufacturing goes down, I get it!!! I get a headache when I see your name.

The main reason is, there are three HD trucks allowed to be sold in the US do to a old tax that keeps out true competition!! I have said before that if VW was allowed to make and sell a HD truck in the US I would buy one and you GM dealers and customer service reps would never here from me again.

OK that would not be true as I will be here until I die making sure all know that GM has NO customer support, and the warranty is not worth the paper it is printed on.

But if I did, I would change dealers. H3ll in the last half decade my GM vehicles have been to the dealership more than the prior 3. Because the GM dealerships are privately owned and operated businesses, and GM can not tell them how to operate!!!

GM can raise the price of parts and vehicles sold to the dealerships, however GM can NOT tell the dealerships what to do.

Just like the tens of thousands in class action lawsuits against GM, for lights, wheels, transmissions, screens, etc. I wonder if there are more people suing GM for faulty parts right now than there are GM dealerships?

Some here just continue to change their names to try to be another GM opinion, but most on this site are dealers, dealer employees, and GM customer service reps!!!The General Motors A platform commonly called A-body was an automobile platformand was GM's original, and oldest, platform used by all early GM products, beginning with the Chevrolet Superior.

The A-body was temporarily suspended in until it was reintroduced in For the model year, the previous A and B bodies were built on the new B Body [1] [2] that lasted until The A-body designation was resurrected in for a new series of intermediate-sized cars including the Chevrolet ChevellePontiac TempestOldsmobile Cutlass and Buick Skylark.

These later A-bodies underwent a switch in drive layout from rear wheel drive to front wheel drive in The switch in drive layout spawned the G-body. Inevery A-body car line was cancelled, but new nameplates on the GM W platform have taken their place. From Wikipedia, the free encyclopedia.

Up Next. As an automobile manufacturer, General Motors is well aware of the building blocks to production success - lesser vehicle platforms than before. In addition to that, GM higher-ups also know that to be competitive in this day and age, they need to offer the neatest platform technologies currently available without increasing production costs. ByGeneral Motors intends to use only four vehicle platforms instead of the 26 it used back in October.

Of course, the C7 Corvette is utilizing a standalone platform, as will the C8 Corvette that may spawn a mid-engined variant. Furthermore, Chevrolet and GMC-branded trucks and commercial vehicles are and will be using specially developed architectures.

It all depends on a highly important element: modularity. The Volkswagen Group proved time and time again that modularity is the answer and GM took notes. Our guide to understanding them all includes the current crop of platforms, as well as the architectures of the future. GM Gamma platform aka Global Small Vehicle architecture - Description: the smallest of them all, this platform is a transverse front-engine layout architecture that can accommodate front-wheel and all-wheel drive.

It was introduced as a replacement for the GM in the year As for engine choices, the platform supports three and four-cylinder motors, as well as electric powertrains Chevrolet Spark EV. The high-strength steel frame gets MacPherson struts at the front, joined by a torsion beam, semi-independent strut suspension at the rear.

It uses a four-wheel independent suspension system. All vehicles use a front, transversely-mounted engine placement. Speaking of which, four and six-cylinder engines are the only powerplants you can get on with the Theta. This metal skeleton is also replacing the crossover-only GM Theta platform. As was the case with the Delta II and Theta, front-wheel and all-wheel drive vehicles will be underpinned by it.

At the rear, the second-gen Chevrolet Volt uses an adapted compound crank torsion beam suspension with a double-walled, U-shaped profile. The Alpha has been developed to accommodate front, longitudinally-mounted powerplants. Aluminum and high-strength steel were employed to make the GM Alpha happen. Thanks to its four-wheel independent suspension and flexible wheelbase configurations, this baby is and will be used for anything ranging from Chevrolets to Caddys.

Not much is known about what platform will underpin the next-gen Commodore full-size sedan. GM Epsilon platform - Description: from to this day, the GM Epsilon played the role of compact, mid-size and large car platform for the Detroit-based manufacturer. Certain reports suggest that Opel developed it in Germany. The P2XX could be used for future full-size vehicles. All that is known at the present moment is that it will be lighter and more rigid than the GM Epsilon II architecture.

Additionally, word on the street is a long wheelbase variant of the C1XX will underpin future models such as the Chevrolet Traverse, Buick Enclave, and a much-rumoured full-size Opel crossover model.

GM's New Digital Vehicle Platform

The platform is modular enough to be adapted for full-size SUVs. In terms of suspension technology, the CT6 will get an updated version of the Magnetic Ride Control system. Engine choices? Full-size SUVs also ride on it. Latest car models:. You will only receive our top stories, typically no more than 5 per day yes no.This List of GM platforms contains automobile platform used both at present and historically by General Motors.

Originally, GM used a Latin alphabet letter scheme to name its platforms, which were aimed at vehicle families in similar market niches. For example, the E platform Oldsmobile Toronado personal luxury coupe was redesigned significantly through four generations from throughbut retained the same letter designation throughout that time.

During that span the vehicle grew from its original " as large as " then shrank to ", and shifted from traditional body-on-frame construction to unibodywith the platform changing but not its designation. In some cases an entirely new platform was developed but given the name of an existing one for marketing reasons, with the original being assigned a new designation. For example, ina ground-up front-wheel drive GM A platform was designed, with former rear-wheel drive GM A platform vehicles shifted over to it.

However, the original A platform rear-wheel drive architecture remained in production, re-designated as the GM G platform. In certain instances, GM has used varied letter designations for similar products. The recent front-wheel drive GHand K architectures are reported to be closely related, but GM has given different letter designations based upon the model produced upon the architecture. In modern General Motors parlance, each platform is referred to as an architecture.

Beginning in the s, GM instituted a naming scheme for its global automotive architectures using the English-language names of letters of the Greek alphabetfor example, "Alpha. Often these are informally referred to by their letter name and the term "-body", as in the GM "A-body". For the Latin alphabet letter platforms, the architecture designation usually corresponds to the 4th letter of the Vehicle Identification Number.

GM used these letter designations to identify service manuals, owner manuals, and other publications. It is common for the automotive press to describe visually similar car families based on their platform designation. For example, the "X Cars". GM uses platforms to make a hierarchy of models aimed at different market segments. The following table attempts to place each shared platform in context. As General Motors has integrated worldwide operations, platforms are now shared globally.

Outside North America, the J platform was adopted by GM-controlled subsidiaries making the same transition to front-wheel drive, though as a mid-size car. ByGeneral Motors began to reduce its usage of the J platform, reducing its usage of badge engineering. As the company prepared the launch of the Saturn S-Series forBuick and Oldsmobile ended their use of the J platform. With its highest sales under the Chevrolet and Pontiac brands, the J platform remained in production into the s, following several redesigns.

The design of the J-body began in the mid s. It was decided that a common replacement would be developed to eliminate duplication of engineering effort and ensure parts interchangeability — a practice known as badge engineering or platform-sharing. In continental Europe, the car was sold as the Opel Ascona. In Britain, it was known as the Vauxhall Cavalier.

Irrespective of badging, European production of the J-body occurred in plants in Germany, Belgium, and Britain. The Vauxhall Cavalier version was particularly successful in Britain, where it was the second best selling car in and and managed aroundsales across a seven-year production run. Isuzu also supplied kits for Holden's J-car version, the Camira. Over its year production run, the GM J platform would be sold under 16 different nameplates five under the Pontiac brand alone.

Aside from several cosmetic redesigns in and along with major powertrain revisions, the J-platform saw few fundamental changes during its production run.

The B platform became GM's base model platform inwhen all existing Chevrolet products were upgraded to the B platform.

For the model year, the previous A and B bodies were built on the new B platform [2] [3] that lasted until During this period, the B was the most modest of GM's three full-sized platforms, slotting below the upscale C and the luxury D.

The GM B platform was introduced in with the Buick Master Sixand the Oldsmobile Model 30and had at least 12 major re-engineering and restyling efforts, in,,and ; along with interim styling changes inand that included new sheetmetal and revised rooflines.

Inthe platform received its last major redesign, regaining several inches in length, numerous frame improvements and reinforcements, while the shorter wheelbase remained unchanged.

The last B-cars rolled off the line inleaving only Ford producing domestic large rear wheel drive sedans until the line was phased out in latewith Chrysler reentering the market with their LX platform in Known for being durable and reliable, most B platform cars used suspensions utilizing coil springs in the front and leaf-springs in the rear untilwhen they switched to coils in the rear; exceptions include the Oldsmobile 88, which used coil springs in front and multi-leaf springs in the rear.

All B platform cars since have used perimeter frames with side rails, along with the B platform Pontiacs and Oldsmobiles. The Buicks and Oldsmobiles used a ladder-type frame while an X-frame without side rails was used on Pontiacs, Chevrolets and Buicks.

The Rear Drive B platform was the last platform design to have the gasoline tank filler port behind the license plate after Exceptions included all station wagons, as well as all cars - which had the tank filler in the rear fender on the driver's side and Buicks which had their fuel filler door above the license plate. Also, the Pontiac B platform vehicles from till had the fuel filler door in the rear fender on the driver's side.

Very likely this would also have been the case with the B platform Oldsmobile and Buick. And inChairman Robert Stempel said: [4]. He also stated that the rear drive Buick Roadmaster and Chevrolet Caprice had been produced "over my dead body.

Hello I'm considering another car. And the platform matters to me because I dont plan on keeping it original. I would like to swap the engine for something bigger for example a olds, BBC or bb cadillac. Manual transmission and posi traction.

Can someone please give me some insight on choosing the best platform based on aftermarket, affordability, and engine swap friendly platforms. And the a body from we could say it's a 64 olds f Also if some one could tell me the cons of the x frame, are the a death trap like I've heard?

Do most engine swaps on the x frame need the frame notched, how does that affect the car?? Thank you. I just want a good starting point because my plan is build a nice st car that's somewhat safe so I can do donuts and pealouts Sent from my SM-JT1 using The H. And are all b bodys from years before the same? GM full size cars were different between divisions up through In they went to a standard design.

The bodies themselves were pretty similar as far as the glass, etc but the frames and suspension were different. Mid size cars starting in were pretty much all the same between divisions. I don't really know for sure what you're asking, though I'm asking which platform would be best to build on. Which of the 3 would pose less problems. You'll find more aftermarket performance stuff for the mid size cars. You'll also get more performance out of them just because they're lighter.

I would pick a car based on how it looks Can you go backwards for a moment. What do you want to put A or B under? And, what's wrong with what's already under what's there? Last edited: Apr 27, Johnny GeeApr 27, Thanks Squirrel. Johnny Gee.
