Standard production model or heavily modified clutch/gearbox and reinforced chassis?

Would have to be the latter- I suspect they'd have had to fit some kind of 'underdrive'.
Theoretically, if allowances are made for friction and air resistance, almost any road vehicle could tow almost anything on wheels if geared low enough. Not very fast though, not far, and not repeatedly.

I'm at a bit of a loss to understand exactly what this is supposed to prove. As long as the plane's tyres are fully inflated and it's running on tarmac, I would expect virtually any competent 4x4 worthy of the name, i.e. featuring a two speed transfer case, to accomplish this with relative ease.

My 79 Chevy half-ton with an automatic could do that. 50 average office workers could do that if you offered them the right incentive; a jelly doughnut and a plaque probably is not going to do it.

Good response Bergamot69.......Pathetic marketing ploy.... have you seen the little vehicles that push these planes in and out of gates? Have you seen the man that pulls a train with his teeth? This is absolutely ridiculous. So it's a record. Utterly useless. Next we will see EZ-G0 golf carts pulling a 747. It means nothing.

This is bullshit to sell the Patrol to the Arabs. As others post, any vehicle or small tractor would do the job. "there is no work done on a flat surface" elementary physics law

I find longevity more important than initial weight. The Tundra Pulled 150 tons for 1320 feet.
Im sure it could pull 170 tons for 164 feet easy.
Plus none of these records are real life scenarios. Its like Phone benchmarks of the automotive world. Who cares.

Meh, Unimogs have been doing this for decades.

Nissan has been doing dumb stuff like this for the last decade, it started when they introduced that tiny little 3 litre diesel to hall a 3 ton behemoth. it was like driving with the park brake on. why don't they just offer a Cummins diesel version?

It's alright getting the Patrol to tow it, biggest problem is hoping the brakes are strong enough to stop both the patrol and the plane.
Once the plane is moving with parking brakes released it should keep going under it's own momentum causing the car very little stress.
I presume they had something there to stop the plane from rolling straight over the car.
I do like Nissan's though, they are good cars. Since I started driving we've had two Nissan Note's, very good and nicely designed cars, just a shame the new Nissan Note has ruined the a bit, my favourite Nissan has to be when my aunty had a J reg Nissan Primera many years ago, and second favourite had to be my 57 plate Note. We now have 60 plate Note, not quite as nice though as it had it's air conditioning unit changed which made it really confusing to use whilst driving, and also the new design does let a lot of draft in. The only let down we have with our cars which is quite ironic is the towing weight - which is only 750Kg on the 1.6 Automatic :(
