Given the choice of the "ecoBoost" 2.3L four and the 5.0L V8 in a new Mustang last spring, I chose the V8 because "there ain't no replacement for displacement". Admittedly, fuel economy is not good, but it's fun to have that much torque on call all the time without having to spin up the turbo.

I once had a small Seat Ibiza with a tiny 1.boring petrol engine, producing all of 75 proud horses. One year later I was driving a BMW 530d, which offered 235 horses and a turbocharger. On the Autobahn, the Ibiza would be stretched to the limit maintaining a relatively slow 140-150 km/h, whereas at that speed the Beemer was hardly doing any work at all. Not surprisingly, at those speeds the BMW returned much, much better mileage. Even around town there wasn't much different, as you had to flog the Ibiza to within an inch of its pathetic life to keep up with the traffic.

Gawd I hated that little Spanish rollerskate.

Here in Ireland, the most commonly bought engine was a 1.6 petrol engine, until road tax rates were pegged against Co2 emissions in 2008. As a result of that, the most common engine is now the 2L diesel.

The Co2 tests in Europe and the US are totally flawed, the engines are run at something like 1,200 RPM, so the turbos aren’t “on boost” and return far better economy than normally aspirated engines, whereas on motorways in particular, a 2L normally aspirated engine will return far better economy than the 1L or 1.4 turbo.

The manufacturers are also permitted to do dirty tricks for the rolling road tests such as decouple the alternator and fill the tyres with Nitrogen to improve fuel economy.

The system is broken. The cars should be tested in a roadworthy condition in towns, rural roads and motorways and the real world figures published and used for certification.

Never happen, the regulators would have to admit they’ve been certifying “junk” data for decades. The companies would be able to say the government standards are “junk” science that is not achievable. Anyone think these two groups are likely to tell the truth? Ha!

How does that work?

Consistent air pressure as the tyre heats up ensuring optimum friction and fuel consumption during the test.

Official MPG tests are often done in Spain during the summer for lower air density (less drag), wing mirrors folded, air conditioning off, radio off, tyres pumped to the max, etc, etc. It's all total bolleaux.

I drive a large turbo diesel and heat my house with oil and wood as the wind blows all the crap towards London.

And, I thought you all were one big happy, environmentally thoughtful, multi-cultural family. Apparently, not so much.

Actually, most tests are done on a "rolling road," not out on an actual road. The problem is consistency; such factors as traffic and weather make the use of a road unsuitable for achieving consistency.

That's where the cheating came in with VW, their development of software that could detect that the vehicle was not on the road, since there were no steering inputs. Then the vehicle was put into "clean" mode to meet test standards, instead of into "dirty" mode to give good performance under real driving conditions.

Now there's discussion about also testing vehicles on the road to ensure that they come reasonably close to meeting standards. That's how the cheat came to light in the first place, when the testers merely wanted to show how clean diesels were. Instead they were baffled by the fact that they came nowhere close to meeting standards.

I am waiting to see if we need to fit an SCR system to the Euro 5 BMW, and perhaps to the Euro 6 Golf as well. An environmental activist wrote a well-reasoned article pointing out that the cost of this to the manufacturers would only be a fraction of the profits made selling non-compliant cars, but I think we would be lucky simply to see them develop SCR retro-fit kits that we would have to pay for: about fifteen-hundred euros per car, plus up to about twelve euros for five liters of "AdBlue," or a lot less if you go to a truck stop.

Another zinger is that we might well see the tax break for diesel fuel removed, when it would then cost about thirty or forty euro cents more per liter.

Basically, we may have picked the wrong decade to buy two diesel cars.

I think we may have found a secret tree-hugger in Galaxy Flyer; he has a lousy little 214-cubic inch German mouse motor under his hood instead of a good old, red-blooded, American 427-cubic inch V8. I bet he wears Birkenstocks when he thinks nobody is looking.

VW are a bunch of con-artists. In the USA they cough up to compensate VW owners for their loss. In the UK they will not pay for the losses of customers, until they are taken to court.

There's an old joke about the cowboy who explains that he wears tennis shoes so that people won't think he's a truck driver.

So ... do you wear spurs as well? Giddy-yap, li'l Mercedes, go!

It’s kinda of J.R. Ewing thing...also fits in at shooting ranges. Sorta like the Confederate flag I saw from the train to Sion once. Startling!

Volkswagen has now admitted, that as late as 2013, it was using monkeys to test the effects of exhaust gases from some of its models.

Germans...gas chambers

What's worse about the animal tests, is that the vehicle was modified so that it emitted far fewer of the dangerous particles than a normal model. As they did the test to prove their engines were 'cleaner', talk about taking a sawed-off and discharging both barrelles into your feet.

Volkswagen to offer buybacks for diesel vehicles if German cities Ban them

Having already bought back an estimated 300,000 vehicles in the USA . . .

German automaker Volkswagen announced that it will offer buybacks for diesel vehicles should German cities choose to ban the vehicles.
