&lt;br /&gt;
The term “1986.5” is not an official Pontiac model year. It is commonly used by Fiero owners to distinguish the later 1986 fastback GT from the earlier 1986 notchback GT.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
&lt;br /&gt;
During the 1986 model year, the Fiero GT changed from the earlier notchback body style to the fastback body style.&lt;br /&gt;
&lt;br /&gt;
Because this change happened during the model year, many enthusiasts refer to the fastback 1986 GT as the &amp;#039;&amp;#039;&amp;#039;1986.5 GT&amp;#039;&amp;#039;&amp;#039; or &amp;#039;&amp;#039;&amp;#039;86.5 GT&amp;#039;&amp;#039;&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
Both the notchback GT and fastback GT are factory 1986 model-year Fieros.&lt;br /&gt;
&lt;br /&gt;
== Why it is called 1986.5 ==&lt;br /&gt;
&lt;br /&gt;
The 1986.5 name is a community shorthand.&lt;br /&gt;
&lt;br /&gt;
It helps identify the fastback 1986 GT without confusing it with the earlier 1986 notchback GT.&lt;br /&gt;
&lt;br /&gt;
The name is useful in conversation, parts discussions, and historical descriptions, but it should not be treated as a separate official Pontiac model year.&lt;br /&gt;
&lt;br /&gt;
== Body style ==&lt;br /&gt;
&lt;br /&gt;
The main identifying feature of the 1986.5 Fiero GT is the fastback rear bodywork.&lt;br /&gt;
&lt;br /&gt;
The fastback GT body style has a different rear clip, sail-panel area, decklid appearance, taillight treatment, and rear styling compared with the notchback body.&lt;br /&gt;

&lt;br /&gt;
== Relationship to the 1986 GT ==&lt;br /&gt;
&lt;br /&gt;
The 1986 model year included both notchback and fastback GT production.&lt;br /&gt;
&lt;br /&gt;
In general enthusiast usage:&lt;br /&gt;
&lt;br /&gt;
* Early 1986 GT usually refers to the notchback GT.&lt;br /&gt;
* 1986.5 GT usually refers to the fastback GT.&lt;br /&gt;
* Both are 1986 model-year cars.&lt;br /&gt;
&lt;br /&gt;

* [[1986 Pontiac Fiero]]&lt;br /&gt;
&lt;br /&gt;
== Engine and drivetrain ==&lt;br /&gt;
&lt;br /&gt;
The 1986.5 Fiero GT used the 2.8L V6 engine.&lt;br /&gt;
&lt;br /&gt;
Transmission availability followed 1986 Fiero GT equipment and options.&lt;br /&gt;
&lt;br /&gt;

* [[Manual transmission]]&lt;br /&gt;
* [[Automatic transmission]]&lt;br /&gt;
&lt;br /&gt;
== Identification ==&lt;br /&gt;
&lt;br /&gt;
A 1986.5 GT is typically identified by:&lt;br /&gt;
&lt;br /&gt;
* 1986 model year&lt;br /&gt;
* GT trim&lt;br /&gt;
* Fastback rear body style&lt;br /&gt;
* 2.8L V6 engine&lt;br /&gt;
* GT-specific exterior and interior equipment&lt;br /&gt;
&lt;br /&gt;
Because the term is informal, documentation may simply identify the car as a 1986 Fiero GT.&lt;br /&gt;
&lt;br /&gt;
== Parts and interchange ==&lt;br /&gt;
&lt;br /&gt;
Fastback-specific body and trim parts differ from notchback parts.&lt;br /&gt;
&lt;br /&gt;
Important fastback-related parts may include:&lt;br /&gt;
&lt;br /&gt;
* Rear clip&lt;br /&gt;
* Decklid&lt;br /&gt;
* Taillight assemblies&lt;br /&gt;
* Sail panels or quarter windows&lt;br /&gt;
* Rear bumper and trim pieces depending on configuration&lt;br /&gt;
* Interior or trim details depending on equipment&lt;br /&gt;
&lt;br /&gt;
Some parts are shared with other Fiero models and years, while others are fastback-specific.&lt;br /&gt;

* [[Part numbers]]&lt;br /&gt;
&lt;br /&gt;
== Notes ==&lt;br /&gt;
&lt;br /&gt;
The term 1986.5 GT is useful, but it can cause confusion if treated as an official model year.&lt;br /&gt;
&lt;br /&gt;
When discussing titles, registration, VIN information, factory documentation, or parts catalogs, the car should normally be considered a 1986 Pontiac Fiero GT.&lt;br /&gt;
&lt;br /&gt;
When discussing enthusiast history or body-style differences, the term 1986.5 GT is widely understood to mean the 1986 fastback GT.&lt;br /&gt;
