Scenario description:
The year is 1962, you are a small sports car company that need a new engine for its new sport car. The new engine will have to be based on a production engine from a large company so you can't change much on the bottom end, the same company wants to use the engine in it's next sports sedan so costs will have to be kept in check.

Technical limitations:

Scenario description:

The year is 1995. The Mazda Mx-5 has reigned supreme for 6 years now. Land Rover has resurrected the British Leyland name and is trying to take back the pride of British roadsters from the Japanese. Their plan is to make a front engined rear-wheel drive car. It must be low weight, inexpensive and, unlike British roadsters of the past, reliable.

• Must be longitudinal
• Must be naturally aspirated
• Must rev to 6500+ rpms

Scenario description:

The year is 1982. The CEO of Chrysler has learned that Renault has plans to revive an old project discarded by a Chrysler subsidiary that was later sold to Renault. They have dubbed it the "Espace". Not to be out done and humiliated, Chrysler is planning to create their own people carrier and plan to bring it to market before Renault. It is your job to make the engine. It must be affordable, reliable and economical.


Technical limitations:

• 3L max. capacity
• Must use RON 87 or lower
• Must be trans-axle
• All other period appropriate technologies allowed.

Technical specifications:

• Cost lower than x (40%)

Scenario description:

The year is 1999. The local 1300cc racing competition have changed the rules on possible technology can be used in there engines.


Your company already produces a 1300cc engine for the competition. It produces X/KW and Y/NM and uses SOHC 8 valve, as that is all the old competition rules allowed. You used to produced the most popular engine in the competition but over the past few years you have slipped to second, your goal is to take back the top spot...

Technical limitations:

1.3L max. capacity
RON not really important but lower RON will win a few extra points
New rules allow DOHC 16 Valve
No turbo allowed
All other period appropriate technologies allowed.


Technical specifications:

Produce more than Y NM (30%)
Produce more than X HP (30%)
Last longer than 1 season between rebuilds (20%)
Cost initial and servicing <= W (15%)
Run on 95 RON or lower (5%)

(ok the idea behind this is that you are producing a racing engine but it is in a cheaper category or road racing and keeping cost down is also important. Longevity of the racing engine is also a consideration, not having to do a major rebuild on the engine after every season and a life of over 5 years is a must).

Scenario description:
Do you remember the scenario where you had to design the cheap engine right after the war? Now, forty years later, in 1986, Cossack Autos became one of the largest car manufacturers. They've been offering the Cossack Tuning Experts, or shortly, CTE models since 1975. Now, they are going to create the 2200 CTE, based on their compact car. And they have contacted you. Remember, it STILL has to be cheap.

Technical limitations:
2150-2250 cc engine capacity
Must run on regular unleaded fuel
no multipoint or direct fuel injection
Anything period appropiate is allowed, as long as you meet the cost restriction.

Technical specifications:
Total cost in 1985 "type region here" factory lower than x (40%) /though we don't have any 1985 factory, we have tested it with 1980 Germany Factory and set the limit there as 350$
Power higher than z (25%) /after some testing, I suggest 170 hp (126.76 kW). As you operate in kW, this limit may seem arbitrary, so, I suggest 125 kW (167.62 hp) alternatively
MTTF higher than y (15%) /3000 MRevs suggested
Responsiveness higher than p (15%) /35 suggested
Service costs lower than q (5%) /850$/year suggested - Kubby

Scenario:
Cheap, Reliable, economical engine… Haven’t the Japanese been doing that for years?

The year is 2020, oil prices at an all-time high and becoming increasingly more difficult to obtain. Drastic measures are called upon: Located in the USA as a large Auto manufacturer the US Armed services have sent your company a top secret objective... Create a fuel economic engine with enough power to drive the front-lines against Saudi Arabia.
After burning through most of the global oil supply, Saudi Arabia remains one of the few countries with a substantial reserve. In recent years Saudi Arabia signed a contract with china, this guarantees China a constant supply of fuel and Saudi Arabia with protection. WE WANT THAT OIL MEN!!


Technical limitations:
Naturally aspirated
1.0L to 3.3L
210 ft lb of torque (284 Nm) or above
Must run on low quality unleaded fuel


Technical Specifications:
Total Cost lower than X (20%)
Economy better than Y (40%)
Reliability better than Z (20%)
Power better than A (20%)

(*Not sure about the Tech Specs)

--------------------------------------------------
I was wanting to think of a way to allow people access to all sorts of modern parts but give them an objective which would be "important".
Hope you like it... ps I don't even know if the game goes to 2020 lol

Scenario:

It's the mid 1970's, the oil crisis is in full effect, brands are trying their best to make economical cars, unfortunately the American brands are falling a bit behind in this, mostly relying on huge engines and even huger cars.
An American brand has contacted you, wanting help changing up their Sports Sedan, the car has a 2.3 I4 with a carburetor, and they want you to build on that engine, make their 2.3 I4 as economical and still sporty as you can, running on the cheapest fuel you can manage.

Tech Limits:
You have to use the 2.3 I4 base.
It for some reason for a 2.3 I4, only comes with 75 HP, you have to improve on that, and still have it reliable, cheap and economic.
You are allowed to make changes to the way the fuel is delivered, as long as it is a cheap low RON fuel.
It needs to be competitive even on the European market.
It needs to be inexpensive to make.


(Edited for I4 engine.)

[Kubboz]

Remember that we are limited to I4s only.
