Yes, it does, but only in short bursts by ERS - if it's working, which wasnt case in most races. Main engine drives only front wheels, so it's FWD

EHHH I wouldn't say FWD it drivetrain is closer to a part-time AWD even if its awd for a short period it still does power it rear wheels.
I think the Saab Sonett mk1 could also be considered a front wheel drive mid-engine prototype racer

Apologies. I confused the front wheel BD7 project with the time I tried to turn it into a 50/50 drift car. At that point I put the spool in the back. When I ran it FWD I had no spool or differential in the rear.

Its drivetrain driven by IC engine is pure FWD, with gearbox in front of engine. I found that ERS, which could drive rear wheels, was disabled in most races, so that car raced as FWD

Just because the IC engine power only the front wheels doesn't make it an fwd, The IC engine in the Porsche 919 Hybrid powers only the rear wheel but it isn't considered an RWD it's considered an awd because just like the Nissan it was designed with the capability of awd. I still which they would have kept working on the nissan tho i like the idea

Oh, and to the op what chassis are you using? depending on the design of the components you can just drill some new holes in the chassis and move the components upfront more this isn't my car but it used to be a losi 4wd chassis to give you some ideas

Here is another example, it is not a losi but it used to be a 4wd chassis to

Since GTRs rear wheels werent powered, it was FWD. It was designed to run as FWD most of time.
Just like AWD rc with removed rear belt, it's not AWD anymore just because 'it has capability'.

I like that losi FWD, with direct drive, it could be serious competition for AWD TCs.
As said before, it's hard to make FWD work without moving heavy components around. Maybe you could use saddle battery pack and place one cell in front of diff, but I think it would be dangerous.

So again it's a part-time AWD system, it had the capability of AWD it just didn't use it. If he has a more modern tc then maybe he can drill new motor mount holes and use the short belt normally used in the rear for the front that way it brings the motor weight more upfront.

By your logic AWD cant be convertoed to FWD, it will be still AWD even when rear drivetrain is not used.

Nissan themselvs calls GTR LM as FWD. Will you argue with them?

No dude if a car is design to be AWD then its AWD the Nissan had an IC engine that powers the front wheel but just because the IC engine power the front doesn't automatically make it fwd. Now if it was designed from the start to just power the front then you would be correct and it would be fwd but it wasn't. But let go with your logic that it fwd what about when the rear wheel is powered would it still be fwd? Not by the definition of what an fwd is, so that why I call it what it really is which is a part-time AWD,

Ford calls the Mustangs a sport car, is the Mustangs a sports car by the definition of a sports car? NO

Well, when it's part time AWD, what it is the rest of time? proper term is part time AWD/part time FWD.

My logic is that AWD/FWD/RWD refers to driven axle in exact moment. Just like when you remove belt on RC and it becomes 2WD, part time AWD becomes 2WD when AWD is not used.

​​​​​​That nissan was designed to run most of time as FWD. Layout, suspension, even tires are designed and setup as FWD.

What's your definition of 'sport car'? Classic british sport cars are sport cars or not?

In normal operation, part-time AWD sends torque to two driven wheels, either the front or rear, depending on the make and model. The system then automatically engages the other two wheels when road conditions demand extra traction. Modern part-time AWD uses an array of electronic sensors that feed information to a computer, which controls the amount of power directed to each wheel. That the definition of a part-time AWD, so again if the layout was designed as an fwd ONLY then they wouldn't have included the ability of the rear wheels to be activated so again it's a part-time awd optimized for fwd but it, not an fwd it an AWD because of that ability of the rear wheels to be powered. Would to add that particular definition is for road cars with a part-time awd for race car depending on the regulation the driver would be the one in control of when to activate it

The original definition of a sport car was any car that seated two, had a soft top, and could be used for competition. If that same car had a hard top then it was called a Grand Tourer

Well, then AWD RC cant be converted to FWD, because of capability of rear wheels to be powered

I thought we were talking about full-size cars? But anyway I don't think you quite got what I said, his taking away the thing that makes it awd so it would be FWD he has nothing that could power the rear wheels back to full-size Nissan would never have done that, they still fully intended to keep the rear wheel drive system that why I said it would not truly be an fwd
