No More Diesel Jeep SUV After 2021

What engines will run our semi's when / if diesels are phased out.

As for the fire thing, this can happen with any make of vehicle, DPF or not, if the exhaust is hot enough and comes into contact with dry grass.

Trucks & Trains maybe not but SUVs & cars..gets back to the original post on this thread. As for the EU see: "End of the Road: Are Diesel Cars on the Way Out in Europe?"
& Germany diesel ban paves way for rest of Europe
Some indicator of the future & FCA have "crystal balled" & decided..the money is not on diesels.

A fully loaded car at it's max GVM weight should ideally be towing a weight less than that. Your car (being relatively unloaded) will weigh less than its max GVM, therefore your 3.0t trailer pushes the boundary even further.

I will have to disagree, as if the equipment is correctly designed and loaded and maintained for the task then it is a low risk operation.

I have driven all manner of trucks in different employment roles my life, and normally the prime mover has significantly less weight than the trailer/s and as long as everything is designed for the task and correctly maintained, correctly loaded etc, etc the operation is reliable and safe and predictable even in emergency situations.

If the tow vehicle was required to be at or a greater GVM than the trailer for safe towing you had better tell the world's trucking industry to scrap all those semi-trailers and B doubles.

As you say, design for the task is what matters. Here we’re talking about a ginormous caravan tethered to the arse-end of a family car. In a semi, the downward force of the front end of the trailer is between the front and rear axles of the prime mover, for starters. Then the trailer wheels are at the rearmost point of the trailer. For stability it’s chalk and cheese between that and anything with a centre axle(s) towed behind the rear axle of a passenger vehicle. It’s the very reason why, if I ever felt the need to own a large caravan, it’d be a 5th wheeler.

Then we'll have to agree to disagree. IMO there's no comparison, the dynamics of a semi are totally different to a car & trailer. A prime mover is designed exclusively for the purpose of hauling a massive trailer. Cars aren't designed the same way or exclusively for towing, and although rated for towing, they have far less stability with a caravan behind. The big difference is a pivoting point that extends out beyond the chassis and even further away from the rear axle. A WDH may lift the rear of the car in order to push the front down, but you still can't change the pivot point. If you've towed a heavy caravan (i.e. heavier than the tow car) you would have certainly 'felt' the difference compared to your semi.

You cannot pick and chose how physics applies to to the tow load based on your personal assertions. The weight and forces don't care if you have a SUV or a truck they act similarly and that is why any towing vehicle/prime mover/ trailer must be correctly designed, maintained and loaded.

But you are right that a prime mover is designed with one role in mind but similarly to achieve a 3500kg tow rating with a modern tow car with the necessary approvals of the various design authorities, it too has been designed and tested to achieve similar expected outcomes when dealing with the physics of the expected loads.

I can assure you most domestic vehicles I have towed with were a more straightforward drive with a correctly setup and loaded trailer than any large truck I have used irrespective of the size of the their trailer.
