Mods for Carmageddon 1
There are few actual modifications for Carmageddon 1 that aren't cars, peds or packs. I'll put uncommon stuff in here. Don't forget to read the readme's, as unusual mods might imply unusual install processes etc. :)

The MELD PACK v1.3.4
details...Famous Carmageddon 1 + Splat Pack meld pack! By JeReMiZ, QTZ and myself. Widely used, it's been recently updated!More infos here.

Figure Of Hate (C1)
details...An early Figure Of Hate net race by Stainless but it didn't make it to the final game. Brought to you by QTZ.

SinCity Palette
details...This palette mod will turn your game into a SinCity look-alike. Eaasy to install and to remove. Good stuff.

Sodburbs (beta track)
details...This is a beta track that evolved into the snowy town track. It's horrible. Desert3 beta is included too, and I offer no support for this :) You must know how to install it yourself.

CTT #3 (GTA Track)
details...Little part of GTA1 Liberty City turned into a Carma race. Features the camera block trick.

CTT #5 (Decor swap)
details...Excerpt of the Splat Pack Castle to showcase the use of 'last lap' funks to swap decors in Carmageddon 1. Turns into Doom.

CTT #6 (Rain test)
details...Simple arena to showcase the use of the rain trick and animated sky. Requires Splat Pack or Meld Pack.
Add-on Cars for Carmageddon 1
Adding new cars to Carmageddon is the most common modding players do. Here you'll find all sorts of models to download, from conversions from other games (including Carmageddon 2, TDR 2000 and PSX) to my own models or stuff made by other authors I ported into Carmageddon. Add-on cars for C1 had a boom in the late 2000s, the process to make a C1 car is more complicated and less documented than the C2 equivalent. Be sure to read the included readme's before installing.
Scifi Forklift
details...Great take on the Forklift by Jorma Rysky. Inspired by one of the original C1 concept arts.
DOOMCAR
details...A Doomcar designed by Anonymous and ported to C1 with help from Jorma Rysky. Features shading.

details...AE86 model from Gran Turismo 2, and turned into the Initial D iconic car.
Grunge Buster + tracks
details...Made with Mad Maxine. Has nice tank tracks :) Some hires textures.
Suppressor + tracks
details...Made with Mad Maxine. As if it wasn't already dangerous enough. Hires textures.

SK-666 ("Skeleton Biker")
details...Ported from Castlevania Legacy of Darkness. Some nifty animated parts and stuff.
'Cadillac' Dronecar

Jet Car
details...Back to CWR's original concept for the Jet Car! Features a great thruster effect!

Action Cruiser
details...The car from Ben 10 apparently. Don't remember where the model come from. Made it orange because C1 hates green.

Eagle MK4
details...Updated port of TDR's Eagle... this time with crush datas to make it deform! First ever!
Nemixis CD 12.0 xl-XGT
details...A famous model by SupermotoXL. It has around 23k triangles and uses a 2048² texture. Thus not for Glide mode!
'84 Chevy Chevette
details...This C2 model by Autopilot was a dear favourite of mine back in the day. Decided to bring it to C1!
Fraud Broko 2013
details...Another model by FatCat, a futuristic Fraud Broko this time. So I ported it ingame as well.

Hearse
details...The hearse from Mafia 2. Ported to C2 by Pip The Pest, then I ported it to C1. Comes with a Flower Power skin!
Tashita 2
details...Tashita 2 from Carma 2.
I reworked most textures to make them more compliant with the C1 palette.
Will Smith Mobile
details...Hilarious model by Mad_Maxine. Ported it to Carmageddon 1 for more lulz. Great suspensions = great fun.
Chryslus Corvega
details...Port from Fallout 3. Higher polycount than usual but looks good. Features an attempt at manual crush datas.
The Car
details...Original C2 model by Chevelle. Looked like it was made for C1 so I ported it to C1.
Ice Drone
details...This is the noncar from the MagnaChem ice station. Made it a proper standalone car. Animated hook in cockpit view.

Wehrmacht Truck
details...This model was a 'prop wall' from a WOLF3D mod called Trench Warfare. Used it to test a couple novelty features (flic anims on cars, fake smash).

Chrome God v2
details...This is the re-release of CWR's Chrome God which was also the first official add-on released by SCi. Now it's a standalone and has its bugs fixed.

'88 Nissan Pulsar
details...Original model by Mad_Maxine, ported to C1 by myself. Lots of windows :)

Project-X 2005
details...The original Project X model updated with the 2005 texture from Stainless. Sexy!

Eagle MK3 Alpha
details...This is the alpha Eagle MK3 from early screenshots. It was recovered by Razor for C2 and I adapted it to C1 :)

Baz Mini (PSX)
details...Exported from the PSX version by Errol. The PSX counterpart to the Splat Pack Mini I guess? A funny car really.

Hevy Shovel (PSX)
details...Exported from the PSX version by Errol. Quite a mix of musclecar stereotypes :)

The Spade (PSX)
details...Exported from the PSX version by Errol. A weird item, who would put rims like that on a hot rod pickup?

Murky Marauder (PSX)
details...Exported from the PSX version by Errol. A nice addition. Lot of people like it.

F-08 (PSX)
details...Exported from the PSX version by Errol. Probably the best unique PSX car, features a cockpit image too!

The Viper (PSX)
details...Exported from the PSX version by Errol. Not bad, had to tweak it a bit as the green isn't C1's favorite color.

Custom '42 Jeep CJ-2A
details...Clearly my best work so far. Fully featured add-on, built around a very tiny texture. Might not be good for Glide mode.

Econobrick's Eagle MK1
details...I thought it wasn't to much of a bad idea to put Econobrick's Eagle into C1. Too bad it doesn't deform heh.

Monster Beetle
details...The Monster Beetle from C2. I fixed a lot of errors on the model in the process...

Le Mighty Fist
details...One of my favourite creation. I find it hilarious. Fun to drive too! Based on an idea by TTR :)

Firetruck RC
details...Quite a creative item as well. Not sure how it looks in Glide mode. It's very small and doesn't go too fast. Great for killing peds hehe.

'71 Picard Piranha
details...From Interstate '76. I had to remake that car from scratch (but the textures). Has interior and all. Super fun.

Razorback
details...From Carmageddon 2. It can be seen in the opening video but isn't actually part of the game?! Fixed now!

Hawk/Eagle MK3 beta
details...The early Eagle MK3 concept made it into C2 as the Hawk MK3. Decided to port them to C1. Good stuff.

The Borgnine
details...After C2 I ported it to C1, a true gem. Looks nice in Glide mode too. From GTA3 by the way. Had to be yellow for C1. Added cockpit from Quarantine!

Crowning Gory
details...Superb item for C1. Originaly made by Freddy for C2. I optimized the model A LOT.

Roverkill
details...Another superb item for C1. Originaly made by Freddy for C2. I optimized the model A LOT too.

The Red Bat
details...TTR's take on the Red Bat from Mad Max. The model was nice but I had to optimize it a lot. Won't work in Glide.

The Machine
details...I quickly remade this beast from TDR2000. Overlooked IMO. Won't work in Glide though.

JAWS
details...TTR's port of JAWS from TDR 2000. I optimized the model and put it ingame. Won't work in Glide mode.

The Beast
details...Another TDR 2000 port by TTR. Once again I lowered the polycount and put it ingame. Screws are animated ofcourse.

The New Suppressor
details...I had made the TDR New Suppressor for C2, so I ported it to C1. Not sure it will work in Glide mode. Doesn't replace the C1 Suppressor.

Wastemaro
details...The Wastemaro is an early C2 concept that didn't make it ingame. TTR remade it and I ported it to C1 (after optimisation).

Birdy
details...Birdy was a very early C2 concept but never went further. I remade it completely. A true gem IMO. Fan is animated etc.

Limey
details...Every Carma has its Limey. From TDR, because the model came with the SDK :B Won't work in Glide mode. Animated.

ED101's Jet
details...The Jet is actually an official Stainless item. It was replaced by Tashita. But they hid the textures in a pixpack and the model amongst the files. This is the standalone item I put together :)

Reliant Robin
details...The Robin is a Stainless car that ended up stuck in a block of ice at the bottom of the Hell level. Standalone item I did out of it!

Sor BN 12
details...C1 Port of AdR's model I had put in C2. Comes from the game Fuel Of War :) Custom cockpit image btw.

DeLorean DMC
details...A superb DMC model by Ikraan. I did the C1 setup and I really recommend this item :)

Eagle MK3
details...Ported the C2 Eagle MK3 to C1 :) Shouldn't have diffused the palette colors with the textures but oh well...

Lamborghini Reventón
details...One of my first quick lowpoly model. First made for C2 then put into C1. Looks good but not very Carmageddonish.

Combine APC
details...Decided to port the Combine APC into C1 too. Had to optimize a lot and simplify the model. From Half-Life 2 uh.

PedBasher
details...Wow what a great beast! I like this car. It's from TDR2000. Remade it and proceeded so that it animates correctly ingame etc. Fun to drive, fun to kill!

Renault 5 TRASH
details...Quite a good looking car in C1! I prefer my little R5 in there rather than C2 I think.

Trou Noir
details...My second car ever, ported it into C1 as my first C1 add-on. Looks really good in there, a bit too big though.
