Although open beta builds can be used, are we actually required to do so? Especially since I am still using the current stable release.
And two big luxury carsā¦ starting to think my little I4 thatās small enough to fit in anything but doesnāt have enough power to move it but will at least fail efficiently may not have been the best ideaā¦ but I decided to use it because my turbo V6 of a slightly smaller displacement had similar performance but worse efficiency, and most engine bays are either big enough for a tiny I4.
well. yours are bigger than madriasās
and if iām going for pure efficiency standpoint, iād pick yours because of the weight advantage. turbos on a small engine aiming for efficiency are a bad idea imo. the efficiency it gains is lost because of the extra weight, not to mention the durability penalty, or cost.
but if itās not pure efficiency, then a turbo is pretty justified.
bigger in displacement or size they take up in the engine bay? even though mine is about 1.34 times the displacement its size is still probably smaller because of having less cylenders and being naturally aspirated, the turbo makes up for the width of my cylenders and being an I6 probsbly makes up for the length, mine is probably still heavier though because I used a lot of cast iron(still think it has a AiSi block), mine is more designed for a small cheap city car for a country without displacement taxes(not saying it isnt viable for places with them, just probably not as much) while his is more for a somewhat prestigious and luxurious economy car I think.
i donāt think iāve ever seen this combination of words used together.
and i meant bigger in displacement.
Well thats the first(and one of the only) use I could think of for a tiny economy-tuned I6 with as little care for costs as the post made it seem.
Edit: decided to slap my car and engine together and im pretty happy with how it turned outā¦ goes over 90MPH so it should be able to reach the speed limit almost anywhere, and it gets 28.5 mpg despite being a large luxury car.
2nd edit: a bit luxury car with two wings and two lips, got it above 30 mpg by lowing the downforce.
My engineās a bit of a wildcard. Itās for an eco-car thatās prestige-minded. Kinda the idea of āPut this engine in a small car, get fuel efficiency near a more-expensive hybrid, brag about it.ā

The 2016 Kramer K3 Coupe 2.0 is a great front-engined, rear-wheel drive sports car looking for a better engine. Alloy panels on an AHS steel monocoque keep the weight down while preserving stiffness, and a double-wishbone front suspension with a multilink rear gives it incredible handling capabilities.
It can certainly handle a lot more power (at least twice as much, in fact) with so much excess cooling capacity and a well-sorted chassis, and hereās why:
The stock engine - a 2-liter turbo straight-4 - only develops 220 bhp, which is enough for a small family car but woefully inadequate for the sports car sector. We encourage other users to replace this boat anchor with something gruntier.

For those willing to build a sports or super car from an off-the-shelf platform, we present the JF848, a normally aspirated 4.8-liter flat-crank V-8 developing over 570 bhp. Itās not only small enough to fit in most engine bays, but has an ultra-linear power delivery and is surprisingly economical for an engine clearly optimized for performance, with unusually low emissions. Even with a redline of 8400 RPM, a reliability figure of 80.0 ensures that you will have no worries plundering the upper rev range.
The long and short of it is that I am asking someone else to build a car whose model and engine are from two different suppliers.

Yeah, I think theyāre pretty compatible, so feel free.
@koolkei redesigns are actually not allowed, I should make that more clear in the rules.
Also great entries so far guys!
what do you mean by redesign here?
iām just literally using an engine family and variant i already have from a while ago. no changes was made to it.
redesign as in, no changes are allowed to be made to car styling (otherwise itās just entering a shell).
No problem designing an engine or car now, just canāt be altered at all by participants in the build phase, only make a trim from the ingredients served 
wellā¦ i guess iāll be redoing the fixtures then.
Just out of curiosity why did you use multilink for a sports car? I thought it was more for offroaders or comfort oriented cars, mine also uses multilink but is designed to be more of a luxury car with some performing capabilities(although it does have a glued aluminum chassis and aluminum paneling) and I still wasnt too sure about multilink suspension and was considering double wishbone rear instead.
Quite a few eco engines, Iām glad I went with a muscle car engine instead.
I think people were too afraid of making an engine thats too big to fit in most of the cars so we built small engines and we were worried the engines would be to big so we used somewhat large carsā¦ Thatās pretty much how it went for me.
well irl, even the newer civic uses multilink. and afaik, multilink is a great compromise between double wishbone comfort and handling, with macpherson strut strength. but at the price of engineering time, cost and complexity.
but that depends on the type of multilink, a performance oriented multilink design can even surpass double wishbone.

I think what most people were doing is trying to make sure the engines would fit, and small eco engines fit in everything. The āproblemā is that no one yet has made small cars and big engines to fit the pony cars on the field, or the truck. Not really a problem as thereās still plenty of people who could do that.
but in game at least they are also heavier and have the disadvantage of not having adjustable camber which Iād imagine could be a bit of a problem considering its a rearwheel drive sports car so it might have oversteering tendencies that could easily be countered with negative camber with no major disadvantages to doing it seeing as how camber doesnāt affect acceleration from my tests so DW and even macpherson struts have it beat for performance in that sense.
wait what? multilink in unadjustable? did i missed that all this time or something?
also, how many cars/engine are we allowed to provide? iād like if everyone can submit 2. more variance is always better 
nevermind, just checked at it is ajustable, not sure why I thought it wasnt.
