3. Can each engine be of a different o/p level
4. Determination of engine-drive: front-engine drives front wheels etc., or AWD
5. Projected driving characteristics/dynamics of this twin engined car
7. What would be the (high-level) technical roadblocks

This car will be solely performance inclined

Muchas gracias.

The 1942 Chevrolet T17E2 Staghound armored car was powered by
two identical naturally-aspirated, inline 6-cylinder, 4,425 cc GMC-270 carbureted water-cooled OHV engines,
each of which developed 97 bhp @ 3000 rpm.

How did the powertrain utilize two engines, each of which could be running, stopped, or running at different rpms?

Each engine drove its own four-speed GM Hydramatic automatic gearbox. Both gearboxes were connected to a central differential connected to the front and rear axles through a part-time 4x4 two-speed transfer case.

The driver could start or shut down any of the two engines, "on-the-fly" and drive the vehicle on any one or both the engines, as required!

You can read about it here.

Cheers...
Ram

Tiger racing that produced the z100 also had two superbike engines one running each set of wheels .. The car running a motec Ecu did however run two gear levers , one for each engine .. One could shift gears on the fly either on a single engine or shift gears on both the engines simultaneously .. Though the body looks a lot based on the catherham , if i remember correctly the car clocked a 2.97sec to 60m/hr .. Tiff Needell did showcase this car on fifth gear ..

thats true, merc built them 2 A classes that had 2 engines, 1 powering the front wheels and 1 the rear wheels but this was just meant to showcase their engineering and never meant for it to be in production.

look at your typical boeing 737. two engines that have to be exactly synced otherwise the plane will yaw.

Slight yaw can be and is routinely corrected with rudder trim.
Did you know that a 737 can be landed with one engine off?
But do you know how to match two engines turning at different rpms to one rear axle in a car?

The thread heading reminds me a joke.

When the Fiesta was just launched, i went for a test drive and was sharing the drive with another gentle man. I was discussing with the driver about the the two petrol engine options. The other gentle man out of no where asked me, "Are both the engines installed in one car?". Most toughest moments of my life holding the bursting laugh.

Hurricane's turning radius is 0-Degree.

The Hurricane is probably the most radical automobile in the world!!!!! Its simply amazing....... but the fact that you have no direct connection to the steering can freak you out sometimes....

I suppose with electronics and software, but even if they are off by a little bit it should'nt cause any issues. Its just like a AWD car with 30/60 torque split.

Haha, yeah! I came across this one sometime last febuary. One maaaaaad machine this is! Would love to own one!... now if only those wheels could also pan downwards 90 degrees and turn into floats, and the engine could lower itself down a bit into the water and start a special fan... Bond and his Lotus'd look pretty Neanderthal then, eh? :-D
