The best: put 15 gears to prevent future updates.

Re: Longitudinal FWD

They already have that. But cannot deal with high torque, maximum 400 Nm.

The new 10 speed DSG is rated for 500 Nm.

Re: Longitudinal FWD

GM had long. FWD in the 70s, maybe even the late 60s, I forget - Cadillac Eldorado, Olds Toronado... maybe Buick did it for a while with the Riv, but I don't remember...

I think all the old, old Cords used a long. placement for all their front drive cars as well, but I can't be sure without looking it up.

Re: Longitudinal FWD

The Cord used a different layout; Differential first, then gearbox, then clutch and last engine. Straight 8. The bonnet/hood is VERY long.

Re: Longitudinal FWD

Great picture, thanks - So, yeah then, the Cords were Long. FWD, albeit a little different, like an MR chassis/drivetrain geared in reverse, basically.

Re: Longitudinal FWD

Not only the Cord. The Citroen Traction Avant, the Renault 4 and Renault 5... I think this "front mid longitudinal FWD" it's the best one for weight distribution and for a better drivability (long wheelspan).

Re: Longitudinal FWD

Main issue is that I am not even sure we have a lot of bodies suited for this setup, as it would require a lot of space behind the axle or a very short engine.

Re: Longitudinal FWD

Well... the same can be said for the normal front longitudinal. We need a lot of space in front of the front wheel.
I think a lot of body can have a reasonable small engine in the "reverse longitudinal"

Re: Longitudinal FWD

Don't really need that much room, we just need short motors - flat twos and fours (Citroens), straight two and threes (can't think of an example), a V4 (Lancias), and a rotary (again, unsure of an example) would all be great short choices. I know its going to be a while before we get any of those, if we get them at all, but those excite me a lot more than big V12s or 16s. My 2¢.

Don't forget all big Audis, like the A4, Quattro, A6, etc. But those have had the engine in front of the axle for some time, only recently they have moved them to over/behind it. Also, the best selling car down here used this longitudinal FWD for 30 years.

The biggest issues with the layout are more weight, worse packaging (with the engine using up more space, limiting interior room), less safety (as the engine used to move towards the cabin in the event of a front collision, but that is the same as any RWD car), but the conversion to AWD should be cheaper and there is more space around the engine, making repairs cheaper. In case of cars with the engine hanging in front of the wheels, it makes the weight balance, thus cornering capacity, a lot worse.

About the problems with interior room: look what the Citroën DS had

The longitudinal FWD mounted 4 cylinder engine was too high for the bonnet, so they had to move the engine way back in the interior :lol:

Re: Longitudinal FWD

That's really not as intrusive as any other comparable RWD car from it's day, or even later.

I actually miss the transmission humps - when I was younger I would always sit in the middle in the front, and the hump was high enough to let my feet touch the floor. :)

Nowadays it doesn't really matter - everyone seemed to go to front buckets instead of front bench seat. Man, I hate bucket seats...

Don't worry about that most cars have center consoles, and also besides the Acura Vigor made it through with longitudinal mounted Inline 5.

Well, look at the space between the engine and the front of the car :lol:

There could be (if the bonnet was square) at least an inline 6 in there.
