Is it possible to get 30mpg with a rear wheel drive car?

Is it possible to get 30mpg with a rear wheel drive car?

Yeah if it doesn't weigh anything

Why wouldn't it? Just get a fuel-efficient engine to put in.

Do it with my 88 samurai, small engine, small car, drive carefully

Corvettes can get that on the highway

rear wheel drive cars are inherently fuel inefficient because of the long driveshaft

easily

Yes.

GS450h and the Q70 hybrid also

Yeah. Get a Scion FRS. My roommate averages 28 on that.

Drivetrain loss isn't that significant, especially with lighter driveshafts.

It's literally 15%

Yes it is, even the smallest engine RWD car will never get 50mpg like a FWD Geo Metro could.

Mercedes-Benz 200D easily gets that and I'm sure there are lighter diesel cars that get that as well.

Sauce? Sauce on fwd loss. It's a few percentage points to maybe 5% at the very most.

Shit that things gotta be a nightmare to work on the engine.

It's still easier than anything made within the last decade

And a diesel rabbit/golf of the era got like 60 to 70 mpg.

My point though was that the drive shaft doesn't sap that much power all other things being the same. The diff, usually being seperate, will add weight, but the platform itself is not all that influential in final mpg.

The reason you often see rwd with lower mpg is that red are often in a higher segment, heavier and weigh more.

>My point though was that the drive shaft doesn't sap that much power all other things being the same
What about mid-engined cars with transversely mounted engines? You know the ones that have the exact same drivetrain that fwd cars have but on their rear wheels? Do these also magically have 10% more drivetrain loss?

Also what about cars like Peel P50 that gets like 100mpg despite being rwd?

I get 9.8L/100KM which is about 29-30MPG on my BRZ.

Toyota Starlet KP61.

It's easy if you have fucking baby hands

...

Drivetrain loss mostly happens when power makes a corner or goes through a non solid coupling.
Most rwd cars are performance cars or trucks. Neither are designed for fuel economy.

It's not the driveshaft, you dickhead

So any new-ish bmw?
I didn't check but I guess diesel ones are rated over 50mpg?

Then what is it cock snot, or is the mass of the driveshaft zero so no force is necessary to overcome it's inertia.

e46 320d definitely does

When I had a scanguage in my Mercury Grand Marquis (could see how much load the engine was under and drive accordingly as well as a bunch of other cool shit) I could regularly get 29 mpg on my way down to Brattleboro.

So if I can do it in a panther v8, you can really do it in whatever.

About 31 or 32 average in my miata. Still underwhelming for a small light car with small engine

my wifes X3 diesel is AWD and gets ~35mpg's freeway.
