You are tasked with designing and then prototyping a pure 2-seat

Transverse slant straight seven mid engine.

Straight 4 is the correct answer.

But since I have to chose one of those, flat 6.
Lighter, shorter, lower cog.

neither I use a single cylinder 2 stroke engine.

VR6

straight 20 that runs the length of the car until it hits just before the rear axle where the transmission is.

Boxer-6 is more suited to RMR layout so obviously the boxer.

Must be sequential firing and extremely low revving, and stressed-member, so you can feel the wave of firing cylinders.

Also displacement should be <2L.
And pushrods. And 20 separate straight pipes.

>>17191545
Flat 6.

Inline-6, long hood, behind the front wheels, driver and passenger up against the rear wheel guards.

but really its a bait thread to see if anons like porsche or not

straight 5 turbo

Single cylinder of 6L displacement, redlined at 400rpm directly attacked to the rear diff

>>17191963
That would need to be a wide, extremely short-travel cylinder to keep the car from jumping up and down. My 250cc single motorcycle vibrates enough, can't imagine a 6l one.

>>17191977
Enormous stroke, tiny bore.
Fuck physics

Depends. Engine in the back/middle? Flat 6.
Engine in the front? Straight 6, or preferably >>17191658

>>17191545
Are my design goals:
>High CoG
>Obscenely long engine
>Heavier engine
If so, straight six. If not, V6, unless I can get the flat 6 to not interfere with my suspension geometry.

>>17191977
Pussy. Big bore. 20 spark plugs to light it off.

Flat-6 but not that pussy ass Porsche and Subaru shit. This bad boy is 8.8 liters.

straight 8 for sexy long bonnet action

>>17191545
5 liter flat six, single overhead with timing chain, 3VPC (two in, one out), turbo charged.

>>17191545
Neither. I use an inline 5.

either an na v6 or a turbo 4
with the option of a base non-turbo 4 for actual enthusiasts.

A V6.
The car is a retro prototype for General Motors, a Mid-engine, RWD sports car reminiscent of the Fiero.
The front suspension is shared with the Alpha chassis Camaro.
The rear suspension is taken from the front of an Impala.
Engine options are a base model 1.4L turbo for fuel economy. Above that is a 2.5L Ecotec from the Chevrolet Colorado. Above that it a 2.0L Turbo from the base model Camaro. And the top of the line model gets the 335 HP 3.6L V6 from the V6 Camaro.
Suspension tuning is done by Lotus to make sure the thing legitimately handles well.

The car launches as the new Chevrolet Corvair, a retro tribute to both the Corvair and the Fiero.

>>17194282
And because a FWD setup is used in the rear, 4 wheel steering is an option. This combined with GM's Magnetic Ride Control suspension makes it terror on the track

>>17194290
>4 wheel steerign

pick one

>>17194036
The original rotary was already posted here >>17191641

a 4.6 liter flat 6 with a supercharger

>Driver sits behind rear wheels for that massive pendulum effect when skids are being ripped

>>17191977

I had gone between a 225cc dirt bike and a 500cc army replica and I could say that the vibration difference wasn't noticeable.

A counter weight alone should have a mitigating effect

1.4l 14cyl turbo radial.

No, it would just get stuck halfway through a stroke.

>>17195212
Oh yeah, I forgot speakers were free energy machines.

>>17195224
oh my bad, i forgot gas internal combustion engines are free energy machines

>>17195233
How could you forget that?

>>17192899
probably but not the way you are thinking
it would also be far less efficient than a regular electric motor
