Bingo. Whilst diesel says have dipped, they still make up a half of the countries vehicles. Half. It's fine to say they've dropped by a third, but that is a wonderful stat with absolutely no frame of reference to fit it into. A third could still be larger than petrol, so at that point diesel isn't dead and certainly won't be soon.

It's also fine mentioning Germany or even the EU. Very good, except for this is even bigger news in Germany because of the companies involved, and in case you haven't noticed, the EU won't be putting any new laws through the UK any time soon.

It's also incredibly short sighted to suggest that diesel will die given that petrol isn't capable of doing the jobs that a large portion of the diesel vehicles do. Ford doesn't even offer a petrol version of the Transit van, and VW, the company involved in this the most, doesn't offer a petrol version of the VW Transporter Panel van. There's an obvious reason why too - because to get the required torque and power from a petrol engine to move these vehicles, you need huge petrol engines. With that you reduce efficiency and, (and this is the fun bit), massively increase emissions. So you're going to switch all of these diesel vehicles to petrol and think it will reduce emissions with the huge engines that are required? I don't think so. And you are going to ban diesel vehicles from cities? How do you propose goods enter the city? Until we perfect teleportation, that is always going to need a van. And what about those people carriers, which are essentially just vans with windows? My partners mother has one with a petrol engine. This is a brand new Ford, with supposedly a great engine in a small sized people carrier. It does an absolutely awful 35mpg. So the solution of moving it to a petrol engine has increased fuel usage by around 80-100%.

Suddenly this petrol idea doesn't seem very good once you start talking about anything bigger than a Ford Focus.

So lets talk about tax. Want to kill businesses during an already tough financial period? Tax them to all hell. Lets assume you aren't talking about a tax on the vehicle, because in the UK that isn't what's happening. The brand new UK Tax laws (which haven't even started yet) will be a flat £140 tax a year for a car - that's if it's a Ford Mustang, or a Ford Fiesta. First year is emissions based, but the rest of the cars life is £140. So a diesel car will not be getting a higher tax than a petrol car, and even then, tax laws in the UK were based on CO2 emissions, not NOx, which was the problem with the diesels.

So lets say you tax the fuel. In the UK, only agricultural use gets tax free diesels. It's coloured red for identification (hence the nickname red diesel). Businesses can claim VAT back on fuel costs, but not the fuel duty I believe. So if you increase the fuel tax, you end up hurting businesses more than anything else. So those businesses all change to petrol engines, and end up producing even more emissions from the massive engines required.

Diesel is not going away in the next few years. It's not going to die, it's not bad technology, and it's not going to be replaced by petrol. Look at the entire system as a whole as to why this simply is not going to happen in 10 years.

Diesel is more likely to be replaced by electric vehicles. With companies like Tesla now forcing traditional manufacturers to invest in the technology, we'll be seeing large jumps in performance (in all areas) of that in the next 10 years. And electric will provide the power and torque required for the goods vehicles.

We're getting way off topic now, but the end result is this: Diesel is unmarketable at the moment due to the scandal. That means we won't see diesel racing cars for a long time, if ever. However it is a requirement for a LOT of every day vehicles that simply won't work properly or efficiently with a petrol engine. Small cars were already making the transition to petrol (Fords 1L Ecoboost Fiesta is amazing), but there's a very good reason that anything as large as a saloon and larger tends to be a diesel. And that fact cannot be ignored, as it may make the situation even worse.

Cool info! He calculated the output at 612ps running in the GTR LMP in 2mj class, so it should make a good chunk more with the higher fuel flow in the privateer class. Maybe you could post this in the lmp1 engine thread also?

Right now the privateer class has 30% higher fuel flow than the 2 MJ class. That would mean almost 800 hp, if the engine is up to it.

I wouldn't doubt it! It's not a very high revving engine either, so it should have a good range of power.

Anybody running a V12 should have a fuel and weight break because of coolness, double break if it is aircooled.

I'd like to see V8s, V10s and V12s make a comeback, but unless the ERS incentive is relaxed or some part or all of the LMP1 engine rules go back to air restrictors, it won't happen.

Not entirely true. There's a V10 engine for privateer cars on the market, but no one is taking it. Remember Toyota was rumored to go back to a V8 turbo too.

Hindy at Midweek Motorsports is reporting that the ACO and FIA approved rules that will make most LMP1 and LMP2 cars obsolete. It concerns driver position in the cars, but there's no timeline on when it will be implemented.

Audi Sport is gone, TMG threatening to leave, Porsche's long term future uncertain, only one car maker talking about coming in but with some major cost cuts.

IMO, even if TMG's threats are just saber rattling or mere complaining, after the Audi pullout, there's some cause for concern.

Read dsc's piece on that. There isn't any threat to leave. They're planned to stay through the current rules and as long as hybrids stay it seems they will.

Indeed! -Also they never let a crisis go to waste: Introduce the old dire need to cut costs based on Audi leaving, although Audi's departure had nothing directly to do with costs being too high. Audi would have left if the costs were 50% of what they are currently. The "Diesel-gate" crisis made it almost a requirement.

Roger Penske says he made an enquiry to Audi about running its LMP1 cars on a privateer basis at the Le Mans 24 Hours this year – but the German manufacturer said no.

That article pretty much confirms Audi left to save face. It wasn't costs, it wasn't technology, it was blatantly "we can't be seen"; probably running a diesel. Pretty sad that the decisions from the road car division had this affect. So bad that not even a privateer team can pick up the pieces.

IMO, any sabre rattling at this stage is cause for concern, since Audi Sport left in large part to save face in the court of public opinion on dieselgate. It also doesn't help that they were probably feeling that the diesel tech had gone about as far as they felt it could go without ditching it for a gasoline engine anyways with the increased emphasis on hybrid tech.

Sadly, all my solutions for getting factory teams back into the series at least partially means "going backwards" with the rules, such as bringing back air restrictors and engine displacement limits, and bumping up minimum weight back to at least 900kgs.

Granted Audi very well may be back by 2020--provided that the rules give them the scope to do something different than Toyota and Porsche, even if they have to run a gasoline engine. I think that's where talk of the hydrogen hybrid comes in.
