Off Topic Cars

Back when I was at school my mate's dad had a Sierra Cosworth. Probably the ugliest car ever to turn into a track car.

 

Ban request going in for that. How dare you diss the sierra cossy.

You go cycling in bowling shoes ffs!

 

And surfin in park ponds

 

The Escort Mexico I'm down with, but a Sierra, ****ing fug ugly mofo of a car.

And the bowling shoes are waterproof so **** you

HIAG's cossie.

 

can't see these pics

One of my uni mates was a mature student. Her and her hubby bought a cossie and it was stolen within a week.

Few weeks later they were driving along and their cossie overtakes them. They call the police after following it to a house and get it back after all the **** is taken care of

Week later cossies knicked again

 

I THINK the air suspension is an option ?

Air pollution: Are diesel cars always the biggest health hazard?

Image caption Modern diesel engines are equipped with filters to reduce particulate emissions
Sales of diesel-powered cars fell dramatically last year, declining more than 17% compared with 2016.

People within the industry blame anti-diesel rhetoric from the government, local authorities and clean air campaigners for eroding consumer confidence.

They insist that modern diesel engines are actually very clean and the health risks have been overstated.

They also say that they can play a vital role in helping to cut carbon dioxide emissions, in order to meet climate change targets.

So have modern diesels just been getting a bad press, or do they represent a serious health hazard?

The reality is not as black and white as you might think. It's true that some diesel engines produce fewer toxic emissions than some petrol engines, but by and large petrol remains the cleaner option.

Although both petrol and diesel engines convert chemical energy into mechanical power by burning fuel, they do so in different ways.

A diesel engine should, in principle, use less fuel and produce less carbon dioxide than a petrol engine with the same power output.

However, this superior efficiency comes at a price. Diesel engines produce higher levels of particulates, microscopic bits of soot left over from the combustion process.

These can penetrate deep into the lungs, causing irritation and potentially triggering asthma attacks.

Particulate filters
The greatest danger lies with the smallest, so-called "ultrafine" particles, according to Dr Matthew Loxham, a research fellow in air pollution toxicology at the University of Southampton.

"They get so deep into the lungs, they get to the surfaces where oxygen enters our blood, and the particles themselves almost certainly can enter the blood," he says.

"They can cause increased stroke rates and increase heart attacks in people who are most susceptible, who have underlying health conditions".

However, modern diesels actually emit very few particulates - because they are equipped with special filters.

According to Emissions Analytics chief executive Nick Molden these systems work very well.

His company carries out its own real-world emissions testing - as opposed to the tests used by manufacturers to certify their new vehicles, which until recently were exclusively laboratory-based.

"Modern diesels essentially do not have a particulates problem," he says. "The filters clean up 99% of the particles. So long as they are not tampered with, they are very effective".

But diesels also produce nitrogen oxides, or NOx - and how they deal with those is also very important.

Long term exposure to nitrogen dioxide in particular can decrease lung function, increase the risk of respiratory conditions and exacerbate allergic reactions.

Effective technologies do exist that are capable of drastically reducing NOx output. In addition, the current European emissions standard, Euro 6, sets strict limits on how much can be produced.

Euro 6 has applied to all new cars sold since September 2015. The legal limit on NOx from diesel engines was halved compared with the previous standard, Euro 5.

The Society of Motor Manufacturers and Traders says the latest diesels are "broadly on a par" with their petrol equivalents in terms of their impact on air quality.

According to Emissions Analytics, however, the reality is not quite so simple.

Road testing
For a start, cars often produce more NOx when driven on the road than they do when tested in the laboratory, and some models turn out to be much dirtier than others.

The worst performers, it says, emit up to 15 times the laboratory limits when used in "real-world" conditions. Others produce no extra at all.

The real-world emissions of petrol engines also vary widely, however. So while Emissions Analytics's research suggests that petrol cars remain on average cleaner than diesels, there is a degree of overlap.

"If you take the cleanest 10% of diesels and the dirtiest 10% of petrol cars, then actually the petrol models will have double the NOx emissions of the diesel ones" says Mr Molden.

It's fair to say, then, that some diesel models do compare favourably with their petrol equivalents, but they are currently in a minority.

However, the introduction of mandatory on-road emissions testing for new models in the EU, which came into force in September, should start to bring down emissions levels overall.

Meanwhile, manufacturers are also trying to make petrol engines more efficient and economical - using so-called "direct injection" technology.

But that improvement comes at a price. It can mean they produce much higher levels of particulates.

So there is a risk petrol engines could actually become dirtier.

 

It’s certainly a factor this stuff about Diesel engines and is making me think twice as to whether to get another big Diesel engine.

Especially when you consider I only do 7-8k miles a year.

 

new lexus lc..nice..very nice

I was always an Evo fan myself, over the Subaru. Two stunning cars though, Tommi Makinen's Evo VI was the best imo.

 

The MK1 was the THE Mexico.

 

Ugly as **** the pair of them, great drivers cars like, but they used to scream chav on the streets.

 

Always preferred the 2. A nice 2.5 Millington Diamond in a mk 2 is a thing of beauty, I think the Mk 1 looks too sensible.

Subjective innit, I think that Evo looks awesome. I'd also have a Lancia Delta S4 over a Lamborghini Aventador though, so make of that what you will.

 

@Sweats. any update?

 

No..

Got a few searches set up on autotrader.

Think I may have decided not to get a big diesel.

Search now is Audi A5 2ltr Quattro
TT DIESEL QUATTRO.
MERCEDES 220 coupe.

 

All nice cars.

 

Get one of each mate

 

Unless you’re a hairdresser ditch the idea of the TT ffs.

The A5 is the best car there by a street.
