In GM, "XP" was "experimental". It could be a concept, it could be an internal prototype (like the 727), it could just be a set of designs on paper. --- Post updated --- Here's a sketch of another stillborn GM four-door - the Cadillac Allante sedan.
In 1987, after purchasing AMC, Chrysler planned to make a Jeep-badged variant of the K-platform Aries/Reliant. A few prototypes were made, but this one, VIN number 3B3BK46K8KT960404, is the only survivor and it is currently in private hands. The car never reached production because I made all of this up and I threw this picture together in photoshop in like twenty minutes.
Therapist: 4 door allante doesn't exist it can't hurt you 4 door allante: in all seriousness i feel like that's a cursed image idk why. -EDIT- k so maybe i have too much time on my hands but:
Speaking of 2-door wagons, GM had envisioned an F-body-based shooting brake a few times: https://www.hemmings.com/blog/2015/04/16/breadvan-bird-remembering-pontiacs-firebird-type-k/ EDIT: Link fixed
"GM targeted a selling price of around $16,000 for the Type K, at a time when a base Firebird was priced from $4,753 and a Trans Am from $5,889." Now that's a high price...
Between 1935 and 1937 the Polish state-owned engineering firm PZInż (Polskie Zakłady Inżynieryjne) worked on a car called the 403 Lux-Sport, powered by a 95 HP 3.9 V8 with a 4-speed semiautomatic gearbox, and with a wheelbase of 340 cm (134"). The project was cancelled when the car's projected profitable price was determined to be over 40k PLN - about twice the price of a more powerful comparably-sized Buick or Chrysler, and well over the original goal of 24k PLN.
This is sort of not a car.. but is related. The famous Citroen DS was conceived to have other engines. V*, Flat 6, and even a rotary
The article clearly states that it was meant for production, and even mentions its approximate projected price.
In the early 90s Mercedes was planning to make a 3-bank 18-cylinder 8-litre engine, codenamed M216. The engine was supposed to have two versions - a 490 HP, 750 Nm (553 lbft) one for the Mercedes 800SEL, and a 680 HP, 800 Nm (590 lbft) one for a hypercar. Unfortunately, the MB engineers decided their 6.0 V12 was enough.
You sure they were to be made in India and China? From wikipedia: "Since 2009, the owner of the brand Moskvitch is the German automotive company Volkswagen. In 2011, the company extended its brand ownership rights until 2021, a 10-year period."
The russians have got quite a few cars that never entered production... 1. V6 Volga 24 The Volga 24 was meant to have a V6 engine instead of the weak i4 it got in the end. The job of designing them was given to GAZ and NAMI, the latter just cut two cylinders off the Chaika's V8, but GAZ's engine was designed from the ground up and was to be made in three variants - two for the Volga and one more for the GAZ-52 truck. Here are the specs : Block was cast iron with wet sleeves, the Vee angle was 60°, valvetrain type - OHV. The 3L accirding to the picture was making 150hp, which compared to Ford's Cologne V6 in 2.9 guise is pretty good, as that was 150 to 160 with fuel injection, while the 24-14 engine was fed by a carburetor. There were prototypes made for testing, but either because of lack of funds or some conflict between GAZ and ZMZ, mass production wasn't started. Instead the Volga got an anemic 4cyl with 95hp(the car weighs around 1400kg)
