Double trouble

Well, this is a system where 2 inline-4 engines are placed side by side (1 for the left and 1 for the right tires,) linked by a computer system that monitors the accelerator and steering. Anyways, pressing the accelerator will make the computer make both engines go forward. Each engine will go at 50% power when going straight. When the brakes go on, the engine stops. When you press the accelerator and turn, 1 of the engines stops , the front wheels turn and the other engine goes into full power and you have a very quick turning system. The transmission has 2 driveshafts, so that the power can be distributed equally. The fuel tank will be slightly enlarged as well. Pretty neat, eh?

//These already exist...and they float//

Yeah? Give me a link, then.

Maybe I've misunderstood but this sounds a lot like the systems used on Harrier jump jets and recent designs of helicopters. Is that what this is or have I missed something?
-- harderthanjesus, Aug 22 2004

No, this has nothing to do with jump jets or british planes. It is 2 synchronized I-4 engines (see main idea.)

They float because throttle managed twin engines exist in boats. They can pivot about their stern due to differential power and, in the extreme, reversing one.

The Harrier uses thrust vectoring during low speed flight rather than differential power settings. The engines run at a constant power setting.

The twin turbine arrangement in helicopters is a mirroring setup designed for redundancy and, like the Harrier, do not use differential power settings between the engines. They are constant speed.

this is already baked in the form of a front and rear engine car. I know it's not the same, but simular. The car that I am thinking of has an automatic tansmission on both engines, one for front one for rear. It does cool brunouts when one is in reverse and the other in drive.. [See Links]

That 6 wheeled ATV would also need to play the song from "Moon Patrol" over and over. To shut it off you would have to stop.
