Kazakh Sportscar
1996 - Year ago, your company built a taxi for Kazakh market, and, thanks to guy (Wasn't it you?), who modified the engine for it, it was really successful car. They were gradually widening the range of their models there. Now, they want to create a cheap sportscar for them. And they approached you to create an engine for it. Remember, it must have reasonable lifespan, reasonable power, reasonable cost, reasonable economy, reasonable size and reasonable service costs. And it has to run on crappy fuel, just as the taxi did.

Technical Limitations:
Manufacturing year 1996
Low quality unleaded (RON 80).
Size less than x x y x z

Technical Specifications:
Power greater than X (30%)
Lifespan longer than Y (20%)
Cost lower than Z (20%)
Economy less than A (15%)
Service Costs less than B (15%)

Scenario Description:
it's 2015, after the F1 economic crash cause by boring races the federation deliberated for the creation of a new formula for experimental designs. The objective of this new formula is to promote technical improvements, without arbitrary technical restrictions but with placing far fetched, long term objectives.

You are to design an engine for the 2020 championship, wich was selected from the committee to focus on emissions. Note that the 2020 year regulations also mandate no refuels and no tyre changes, so the engine must run to the end without refuelings with the stated tank upper size limit. (there is no a lower limit so saving in consumption will save weight too!)


Technical Limitations:
standard unleaded fuel

Technical Specifications:
a) engine power more than x (60%)
b) engine wight less than y (30%)
d) fuel consumption less than q (10%)
c) emissions lower than z (00%)

It's 2009, a chinese automaker who prefer to remain unspoken is branching into luxury car market copycatting some of the recent hits from western brands*
for the first prototype they are looking for a new engine that could give that premium feeling to prospect buyers on the export market.


Technical Limitations:
more than four pots
unleaded low grade fuel


Technical Specifications:
a) cost lower than x (70%)
b) smoothness higher than y (20%)
c) torque more than z (10%)
e) emission lower than w (00%)
*true story!

Scenario Description:
It's 1985 and the executives of the American car company you work for have decided to create a modern sports car. This will be a big change from the V8 muscle cars the company made in the past and the bean counters have tied your hands and forced you to use an old 8v iron I4 as the base motor. Turbo power is a new and exciting technology that will allow you to breathe new life into this old motor. This is a post oil crisis world so emissions and fuel economy do matter.

Technical Limitations:
I4
8v OHC
Iron block and head

Technical Specifications:
a) Cost lower than X (20%)
b) power above y (40%)
c) emissions below z (20%)
d) fuel economy better than r (20%)

An idea for scenario in earlier time period

Scenario Description:
It's 1953, Evardsen Motor decided to produce model larger than GT it currently produces. It'll be midsized car, able to transport 5 passengers and their cargo. It's handling will be as perfect as GT's. But it also need an engine, able to retain the Evardsen's reputation. Remember, it does not need to be as cheap as Cossack engines, but it also can't be too expensive. It must have reasonable power, but it must be reliable to withstand scandinavian winters. It also needs to have reasonable fuel economy and it needs to be quiet. And smooth. Oh, and don't go with uber-large V8's. while it is not a compact car, and it's engine bay is not that small, it's still limited. Of course, T16 could design this, and he would do it better that you, but he's...ummm...playing Automation board game

Technical Limitations:
size less than w x l x h
Must run on Regular Leaded fuel
loudness lower than l

Technical Specifications:
a) Cost lower than X (10%)
b) power above Y (30%)
c) fuel exonomy lower than Z (20%)
d) smoothness above A (10%)
e) lifespan above B (30%)

Scenario Description:
Australia 2005. Every old Grandma and Grandad out there are buying themselves a caravan and doing the big lap. And your company is going to cash in while it is clogging up the roads with cars doing 20 below the speed limit. Power doesn't matter, in fact less power might be a good thing, given the eyesight of some. Three things are needed : torque, economy and longevity. Maybe a lazy v8, or a turbo 4 or 6. Whatever you do, make it sound like a car, not a vacuum cleaner.

Technical Limitations:
Uses regular unleaded fuel
Tech year x
Cost less than y

Technical Specifications:
a) Torque greater than a (50%)
b) Economy less than b (30%)
c) longevity more than c (20%)

Let me tell you something.

We've tested a lots of "requires torque > x" scenarios without power requirement. It simply didn't work. The problem with them is, that they are extremely one-dimensional. We've quickly noticed that the only way of scoring high is going for the torque just meeting the spec at 2000 rpm, and having very, very large MTTF numbers. When there is only one way of completing the scenario, then the fun factor of it is severely decreased (Actually, it's only happening in tutorial scenarios, when there are limited options, so the player does not get lost).

[LoSboccacc]

interesting stuff! so that's why the current scenario doesn't have torque

what about turbos? those should give huge torque at higher ranges, maybe increasing variations?

Scenario Description: The year is 2001 and your company is doing men everywhere a public service. Because more and more of them are forced to buy family people carriers, your company has decided to make a van for a man... a man van! It most be loud and powerful, however it most also get decent economy. It must also have ridiculous longevity so that they can sell it to teenagers in 10 years with far too many miles on it.

Germany 1986 - The turbohype is ongoing, and even your boss got infected with the turbo-virus, he wants to release a new series of executive cars, price isn't really a issue, but they should have some power and because the emission regulations are getting stricter, it needs to have a bit lower emissions and economy then usual. He forces you, to take a small V12 and put loads of turbos on it, all the warnigs of other engineers are futile.Only you can convince him, that other engine concepts could work better.

People are attempting to race from the southern tip of Africa, up to the Mediterranean, in purpose built off-road vehicles, with no real rules on their configuration or design. You have been given the contract to build an engine for this event by a wealthy individual, who is using his own customised light-truck. He is smart enough to realise that reliability is more important that power output, and also wishes for the engine to be as light as possible. Fortunate for you, cost is not an issue!

The automotive manufacturer you are working for has decided that they want to show the world what they are capable of, and has described to you their idea of building something the world has never seen before.
