By not 80s Citroen you mean not-BX? If so, I even have a ready test platform - my Etalon 
And displacement should be no problem, I think.
And, what exactly do you mean by fuel efficiency?
Yes… AND a not Alfa GTV, which is smaller.
Hmm… Are there ANY other limitations? Such as engine layout, maximal displacement etc.? Because I’ve just found out that my over 6-litre V12 fits longitidunal into the not-Alfa… 
Also must be awd. Something about 4 liters, turbo, not more than 8 cylinders. No less than 6. As light as possible, output about 330hp, potential up to 500+ on 91 ron with good economy.
And year?
85
Id be willing to design an engine too, send me the car file?
Hmm, how far is 475 g/kWh from good economy?
It’s pretty good.
Ok. So now I’ve got a 4-litre turbocharged V8 that gets 326HP and 462g/kWh with material cost of about 2000$. Is it around something you look for?
Oh, and 61 production units, about 240 kilos - so the weight isn’t small.
Pm it to me, it’ll go through the separation process with the other engines sent in. We’ll have to see who gets the contract once all who were interested send in engines
#1985 C3
Having experienced moderate success at selling the 1981 NOTO C1 Scura, KHT has seen the need to continue the production of the platform. By 1982 course of action was developed, first re-working the transmission and suspension, to provide for a more competitive car.
1981 Noto C1
The first tests on the new components were conducted in 1983, when the C1 was upgraded to the international “Category 5” standards, used for “survival of the fittest” challenges. The evolution model had the name C2 and was not available to public. The components tested by motorsport were the new suspension and improved drivetrain, which was still a 5 speed manual, now sporting un-even split. Suspension featured new more rugged settings, allowing for even higher offroad abilities. The whole car got upgraded to help it survive the full racing challenge, but sadly the race conditions were not ideal for the C2, with speed being on par, yet the car proved too tricky to drive fast.

In 1983 KHT has formed a partnership with Inline designs, who were to provide the new engines for the upcoming C3, as well as for the KHT Nemesis. While the Nemesis could do with a v6, the front engined v8 was a formula with which KHT did not want to part, since the 60’s. In 1985 the first engines were put to the test in C2 mules and racing trims of those in the 1985 Survival of the fittest. The C2 Category 5 Evo model was once again, unavailable to the public, as it was only a test bed for new technology.

By 1986 the works have been done in the test mules and the new model, named C3 was to be released, sporting a brand new body, by a brand new chief designer, Marco Noto’s protege, young Klaus Hilleman, who in 1986 became KHT’s new chief designer, allowing Noto to concentrate on the management duties. The now proven technology has been finally installed into the new shell, and a car, similar to the outgoing model on the inside, yet very futuristic on the outside has seen the world
1986 KHT Noto C3
The 4 liter v8, helped by twin turbocharges now produced 330hp, transferred to the road via a 5 speed manual with overdrive, to all 4 wheels at 40/60 split. That was enough to propel the 1250kg car to 100 kph in 4.1 seconds and to top out at 265 kph, a result formidable to this day. The idea of lowering the production costs meant that the engine only had 16 valves, and used a bit dated ECU settings, but the upside was the engine turned out to be about 30 kilograms lighter than the initially drafted prototype, while retaining high reliability and easy access to power shall the owner want the car to be modified.
The interior now consisted of a much nicer sports cabin, clad in quality materials, and unlike the c1, it even featured the stereo, and unlike the c1 a lot of attention was given to safety and comfort of the driver and passengers. The C3 was a succes, costing at $34,000, cheaper than the C1 it replaced, which allowed the factory to grow over the years and bought much needed breathing space to the company.

You have reminded me that I need to make my own car company still. And actually make cars for it. 
Nice one, looks very… eigthies Although I prefer C2 race cars, I somehow associate them with B Group, which I love 
What vents did you use on the sides of them? I don’t recognize them, and the effect looks good.
And it seems that I’ve failed in something Something particularly, or the whole engine?
Those are Gallardo vents. Also overall your engine is more expensive and heavy than the engines others have sent in, with the one from Inline able to over 500hp also.
Meh. Seems that I have overall problem with weight in Automation. My third try on a hypercar - this time with a not McLaren body - is like 100-200 kg too heavy, and I have no idea why.
#1990 Tsukuba
By 1988, KHT Atlantic has been released, and with the feeling of his job being done, loyal KHT materials specialist Claus Hoch has retired, having dedicated over 30 years to the company which goal was to go fast. The new age of materials was upon the motoring world, and it demanded new approach, which was delivered by KHT’s new materials specialist - Tadao Ueno. Having examined previous works by KHT young Tadao confronted company’s CEO on the wrong direction the company has taken, with the Atlantic, it being a dated design even before it was first conceived, heavy and inefficient. The CEO Marco Noto has reluctantly agreed to hear the ideas of mr.Ueno. A few weeks of brainstorming and discussion between the CEO, Materials specialist and marketing director have come to a fruition in a conclussion that a new project was required bringing in a new philosophy.
Having seen success of lightweight affordable sportscars, it was decided that KHT would bring it’s cards to the table by presenting it’s own cheap and light sportscar, in to the playing field. Not having a lot of funds to play with, the chassis was a very simple steel monocoque, covered by a very light fiberglass bodywork, designed by the new designer Klaus Hilleman. The interior was one of the things KHT decided to save money on, providing a basic sporty interior with a basic cassette player, the budget cuts also affected the safety and suspension departments, as the car had no outstanding safety features and looked adequate in mid to late 80s in that department. The suspension used the most basic conventional shocks and springs, with conventional antiroll bars to finish off the job.
Deciding to not spend any money on developing an engine for the car, KHT has gone to contact a Japanese automotive giant Saminda, who agreed to provide the H22 series i4 engine from their hot hatch the CZ2. Since the CZ was a FF car, and the new KHT project was an MR it fit easily into the engine bay along with the gearbox, which only needed new cv axles and gear linkage to work properly.
The car was named “Tsukuba” as a nod of respect to Japanese automotive and motorsport culture, which helped shape the project, both as an engine manufacturer and the car’s inspirational father’s home town.
The end result weighed in at 909 kilograms, and was riding on 225 wheels front and 245 rear to give the car maximum predictability. The stock version also came with steel wheels, which was another cost saving measure. The tiny coupe was powered by an unmodified Saminda H22 series engine which provided for 144hp, and pushed to the rear wheels via a 5 speed manual, also unmodified from Saminda, still with an open diff, which was deemed sufficient for the first attempt at a cheap automobile for the sportscar masses.
The performance was quite good, as the car managed to get to 100kph in 6.9 seconds and top out at 211kph. Cornering was easily dealt with at 1.22g and managed a lap of the Green Hell in 9.04.7 . But the main competitive edge for the car came from the same budget cuts that compromised the technical innovation. The end result even after all the generous 100% markups came to a $22.600. The car was so popular (by KHT standards) that it allowed to build an entire facility to mass produce Tsukubas by 1993.

Thanks. I try.
You find really good landscapes for your pics, and these last cars, the Atlantic and Tsukuba are magnificent…, a good balance on fixtures and placed with sense (from pov).
GJ man.
