Following its 1993 discontinuation, the Super-Liner was replaced by the CL700; today, its closest equivalent is the [[Mack Anthem]].
Since 1980, the model line has been sold by Mack Trucks Australia; currently, it is in its third generation.
== Background == The development of Super-Liner began life in the early 1970s under [[Brockway Motor Company]], a subsidiary manufacturer of Mack Trucks.<ref name=":0">{{cite web|url=http://www.stlouisdumptrucks.com/ConvoyMackTruck/BrockwayLegend.html|archive-url=https://web.archive.org/web/20150311210508/http://www.stlouisdumptrucks.com/ConvoyMackTruck/BrockwayLegend.html|url-status=dead|archive-date=March 11, 2015|title=The Brockway - Convoy Connection|date=March 11, 2015}}</ref> While using the cab of the [[Mack R series|Mack R-series]] in its production, Brockway competed nearly directly against Mack in heavy-duty truck sales. Following the introduction of the long-hood "western" Mack RS700, Brockway commenced development of the "Super-Liner", featuring a squared-off hood (to accommodate a larger radiator/engine).<ref name=":0" />
In 1977, Brockway Motor Company was closed down by Mack Trucks, following labor disputes that ended its production.<ref name=":0" /> While much of Brockway was liquidated, Mack continued further development on a set-forward axle Super-Liner, entering production by the end of 1977. As the design already used a Mack RS cab, the Super-Liner saw only minor detail changes before entering production, internally designated as the RW700.<ref name=":0" />{{Clear}}
== Model overview ==
=== American production === [[File:1977 Mack Super-Liner in Ireland.jpg|thumb|1977 Mack Super-Liner (exported to Ireland)]] Introduced during 1977, the Mack RW700 effectively replaced the RS700 "western" conventional. While sharing the cab of the R-series tractors (along with its model designation), the Super-Liner was built on the frame of the WR Cruise-Liner COE.<ref name=":1">{{Cite web|url=https://www.bigmacktrucks.com/topic/30247-superliner-i-vs-superliner-ii/|title=Superliner I vs. Superliner II|website=BigMackTrucks.com|date=March 2013 |language=en-US|access-date=February 24, 2020}}</ref> The first-generation Super-Liner is externally distinguished by four round headlights (in a rectangular housing); the interior has a 3-spoke steering wheel.<ref name=":1" />
For 1985 production, Mack introduced the second-generation Super-Liner, named Super-Liner II. Visibly similar to its predecessor (with the exception of four square headlights), the Super-Liner II adopted the full-length frame rails of the MH Ultra-Liner COE.<ref name=":1" /> Alongside detail changes to the interior, a smaller 2-spoke steering wheel was added.<ref name=":1" />
Following 1993 production, the Super-Liner RW-700 was discontinued. As its replacement, Mack introduced the CL700, a longer-hood version of the CH600; though shifting to a set-back front-axle layout, the CL continued the use of the Super-Liner frame.<ref name=":1" />
==== Super-Liner Magnum ==== To commemorate the introduction of the Super-Liner II, Mack produced the ''Magnum'' special-edition series of Super-Liner IIs and Ultra-Liners for 1985.<ref name=":2">{{cite web|url=http://www.bigmacktrucks.com/index.php?/topic/30380-magnum|title=Magnum|work=BigMackTrucks.com|date=March 12, 2013 |accessdate=December 28, 2015}}</ref> Designed as an appearance package, the exterior of the Magnum Super-Liner was black with Magnum wording on the hood, red/orange cab striping, and a red interior.<ref name=":2" /> The standard engine was the Mack E9 diesel V8 (400-500 hp) with a 9-speed Mack T2090 transmission.<ref name=":2" />
In total, Mack produced 250 of the Magnum special edition for 1985. 186 were Super-Liner IIs, with the other 64 being Ultra-Liner COEs.<ref name=":2" />
=== Australian production === [[File:2007 Mack Super Liner (32695788211).jpg|thumb|2007 Mack Super-Liner III (New Zealand)]] Since 1980, Mack Trucks Australia has produced the Super-Liner in Australia.<ref>{{Cite web|url=https://www.macktrucks.com.au/about-mack/mack-history/1980-1989/|title=Mack Trucks "YEARS"|website=www.macktrucks.com.au|access-date=February 24, 2020}}</ref> In place of sharing the chassis of the WR and MH COEs, Australian-produced Super-Liners shared frames with the R-series throughout their production.<ref name=":1" /> Currently slotted below the Titan, the Super-Liner is in its third generation. Alongside the Titan, the Super-Liner is offered with a 685 hp MP10 engine.<ref>{{Cite web|url=https://www.macktrucks.com.au/trucks/super-liner/|title=Mack Super-Liner {{!}} Mack Trucks Australia|website=www.macktrucks.com.au|access-date=February 24, 2020}}</ref>
[[File:Bicentennial Mack Superliner.jpg|thumb|alt=Captain Cook Mack Bicentennial Superliner II|Captain Cook Mack Bicentennial Superliner II]] ==== Super-Liner II Bicentennial ==== To commemorate the bicentennial of [[Australia Day]], Mack Trucks Australia produced 16 Super-Liner II Bicentennial trucks in 1988. Each example was named after people influential to Australian history, including [[James Cook]], [[William Bligh|Captain Bligh]], [[Ludwig Leichhardt]], [[Arthur Phillip|''Governor Phillip'']], [[Ned Kelly]], [[Charles Kingsford Smith|Kingsford Smith]], [[John Flynn (minister)|John Flynn]] and [[William Hovell]]. The 230-inch wheelbase trucks were fitted with a 500 hp E9 V8 diesel and a 12-speed triple-countershaft transmission.
One remaining example is operated by Eagle Towing Service of Ringwood, Victoria and has since been converted to a heavy towing salvage truck. Two more remaining examples are from Mactrans Heavy Haulage, who own Captain Starlight and Thunderbolt.<ref>{{cite web|url=https://www.truckworld.com.au/blog/truck-and-trailer-news/2007/04/wheels-of-time-super-liner-ii|title=Mack Trucks Australia News : Truckworld.com.au|work=truckworld.com.au|date=April 30, 2007|accessdate=October 14, 2024}}</ref>

== Appearance in media == In the 1978 film [[Convoy (1978 film)|Convoy]], a Mack RS700 is driven by main character Martin "Rubber Duck" Penwald ([[Kris Kristofferson]]). As the film was released after the replacement of the RS700 by the Super-Liner, Mack inserted the Super-Liner in all promotional materials and products related to the film.<ref name=":0" />
In the [[Cars (franchise)|''Cars'' franchise]], the character "[[List of Cars characters#Mack|Mack]]" was inspired by a 1985 Mack Super-Liner.
