Carbon emissions - superiority of German technology

[Caravan]

While browsing sgcarmart and checking out vehicles specifications, something caught my eye - carbon emissions. With the new CEVS kicking in from July, cars with 'high' emissions can be taxed additional $30k! But what is interesting is how the German vehicles have much lesser emissions than comparative Japanese cars. Examples below. Specifications from sgcarmart.

 

Toyota corolla 1.6(A) - CO2 emission 151 g/km (As tested by LTA) / Kerb weight 1,265 kg

 

Mercedes Benz E200 - CO2 emission 146 g/km (As tested by LTA) / Kerb weight 1,655 kg

 

Numbers speak for themselves.

 

Further e.g.

 

Subaru WRX STi 2.5(M) - CO2 emission 242 g/km (As tested by LTA) / Kerb weight 1,516 kg (additional $30k CEVS tax from July)

 

Mercedes Benz A45 AMG - CO2 emission 165 g/km (As tested by LTA) / Kerb weight 1,555 kg

 

Seems like the German technology is far ahead of the Japanese.

But come SG kenna tax cos too much HP for small engine

[F355]

Superiority of German technology nullified by Stupidity of LTA prodigy .

 

On one hand it wants to encourage greener vehicles thru CEVs , but at the same time penalises it by reclassifying them into Cat B . Well done .

Couple of things cross my mind.

 

Is CO2 the main culprit or even a good indicator of how 'noxious' a vehicle's emissions are?

 

Can it be that when tested as new, you get 1 set of numbers but on the road in actual conditions, and after car ages (esp for cars with more maintenance issues), you get another set of numbers which might turn a 'lower' emitter into a higher one?

Not sure what to say about the second one, but mostly people say cars fuel efficiency get worse as they get older, right? Probably the emissions get a bit worse over time too, but not a huge difference. Since engine performance no longer optimal and got corrosions inside.

 

As for CO² being main culprit, carbon dioxide is always the biggest worry in global warming, but of course there are other stuff coming from cars, I think nitrogen oxide also is a major pollutant. For example I think the European side now wants to change legislation regarding diesel cars because those have low CO² but high NO².

For Toyota Asean cars, it is using older technology which contributes to higher carbon emission.

 

For Altis, it is using dual VVT-i now, 1ZR-FE.

 

On the other hand, the latest ZR is xZR-FAE included valvematic which can varies intake height depending on engine load.

As car ages, CO2 will increase from wear & tear.

 

In Germany, one of the reason for inspection is to ensure CO2 emission still within tolerable level.

Drivers driving green cars are selfish. They stave the tress & plants by limiting the carbon footprint. If no food (CO2), how can they produce oxygen (H2O)?

 

So am I not green by producing carbon dioxide which is providing more food sources for the plants to produce oxygen.

 

Jokes aside, government should take lead in greener country.

 

- Reduce paper works.

- Why having higher tax for greener vehicles?

- Why have higher tax for better petrol grade when cartels do claim that better grade = more inefficient & cleaner.

 

I remember tuck you once claim the COE system has backbone which a solid backbone doesn't require changes.

How many times under his lead the COE system has changed?

Don't talk about Quota issues but changes in general system.

 

1) BHP

2) CEV

3) Revise CEV

SORRY AH BACK TO SEC 1 SCIENCE

 

 

Is it CO2 OR CO?

 

Carbondioxide is what we exhale. If what we exhale is the same with car I think we wont live long lol

 

 

 

 

 

 

 

So is it carbonmonoxide or carbondioxide?

Both sia. From car that is. Monoxide will kill human. Carbon dioxide also will kill human if too much.

 

But carbon dioxide is what plants use to make their sugars. But when too much carbon dioxide the plants also don't photosynthesize it as fast as the amount of carbon we put out. Plants also put out carbon dioxide when they not photosynthesizing.

 

Then of course our plants now become roads... and car trim inserts...

[Thaiyotakamli]

Normally imperfect combustion will emit carbonmonoxide while perfect combustion will emit carbondioxide?

If it is so high co, I think your engine very special

 

Incomplete combustion engine

Eh..... this I think now P6 study already....

Heng my generation is sec 1/ sec 2 then study haha

 

 

If i go back primary school now dont think can pass psle lol

Back to OP. I have done some research. Yes the Germans employ more high tech stuff for sure. Some of the jap offering, really no eye see.

 

But some savings are gained using technologies that are not practicable or having serious drawbacks.

 

For example, engine start stop. That's bad for the ignition system. Cheap to implement though.

 

Electronic steering. Saves fuel but no feel. See the new 3 series compared to previous gen.

 

DSG or 7/8 AT. DSG is complex, sure to have more reliability and maintenance problems down the road. Also see the infamous dry dual clutch in cheap vw card. 7/8 AT is good and hopefully as reliable as your old school AT. Jap offerings go for cvt, which is cheaper but less transmission feel.

 

Turbocharging plus smaller cc engine. Well turbocharging uses more parts than NA so also cause more maintenance headaches. Though with maturing technology, there ought to be lesser problems. The whole world is moving in this direction. The non Germans are late to this game.

 

Weight savings. That's the gem, I dont see any drawback here, if safety not compromised.

 

Happy to discuss any relevant technical features.

I saw the you tube acceleration of the 2015 wrx CVT. 268bhp with CVT. 0-60mph at 5.9s. Seem like a single speed run with rpm at 6000revs but the speed just run up to 60. No jerk no gear shifting. Maybe a better system for comfort and wear.

Sure, I am pretty convinced that any machine that ages gets more inefficient. But my point was that:

 

New:

 

Car A with iths many tech gimmicks : Produce 100 units pollution

Car B with basic mechanicals : produce 130 units

 

After 5 years, Car A has half of its n gimmicks worn out or not properly maintained : Produce 160

Car B age a bit : Produce 140 units

 

I used to work for a company with a big fleet of diesels. When the spanking new Euro 'X' vehicles arrived, can see tailpipe no smoke even on full bore acceleration. After some time of drivers abusing the company assets, half load also smoke like burning barnyard. Even a better cared for Euro 'X-1' or 'X -2' vehicle produces less smoke.

That's very typical Singapore driver.

 

I saw taxi in Germany that has no smoke at all.

 

It all boils down to maintenance. The more tech gimmicks, more TLC.

 

I am surprise that smoking vehicles can pass inspection.

Taxi in Germany owned by driver. Nuff said.
