Apple to apple comparison, diesel engine more efficient and green than petrol and sometimes even beat hybrid! smile_thumbup.gif

Using Porsche Cayenne for comparison:-

http://www.porsche.c...models/cayenne/

i. Cayenne S Hybrid

Layout / number of cylinders 6
Displacement 2,995 cm³
Engine layout Front
Power Combustion engine: 245 kW (333 hp) Electric machine: 34 kW (47 hp)Total system:279 kW (380 hp)
Max. torque (Nm) Combustion engine: 440 Nm Electric machine: 300 Nm Total system: 580 Nm
at rpm Combustion engine: 3,000 - 5,250 1/min Electric machine: < 1,150 1/min Total system: 1,000 1/min
Compression ratio 10.5 : 1
Top speed 242 km/h
Acceleration from 0 - 100 km/h 6.5 s
Acceleration from 0 - 160 kmh 16.5 s
Fuel consumption Tiptronic S
Combined in l/100 km 8.2
CO2 emissions in g/km 193


ii. Cayenne Diesel
Layout / number of cylinders 6
Displacement 2,967cm³
Engine layout Front
Power 180 kW (245 hp)
Max. torque (Nm) 550 Nm
at rpm 1.750 - 2.750 1/min
Compression ratio 16.8 : 1
Top speed 220 km/h
Acceleration from 0 - 100 km/h 7.6 s
Acceleration from 0 - 160 kmh 20.0 s
Fuel consumption Tiptronic S
Combined in l/100 km 7.2
CO2 emissions in g/km 189


iii. Cayenne S (Petrol)
Layout / number of cylinders 8
Displacement 4,806 cm³
Engine layout Front
Power 294 kW (400 hp)
Max. torque (Nm) 500 Nm
at rpm 3.500 1/min
Top speed 258 km/h
Acceleration from 0 - 100 km/h 5.9 s
Acceleration from 0 - 160 kmh 13.9 s
Fuel consumption Tiptronic S
Combined in l/100 km 10.5
CO2 emissions in g/km 245


Cayenne Diesel consume least fuel and produce least CO2 compares with Cayenne Petrol and Hybrid!

Haven't take into account that production and disposure of hybrid batteries polute the environmental futher.

Ok, our local diesel quality screw up, Porsche Diesel probably irrelevant here. smile_tongue.gif

that's also why EC gives incentives for diesel vehicle owerships and the European maker even went further producing smaller engine capacity with turbo charged to churn attractive hp. see recent releases of European vehicles... even the petrol Pug 508 is only 1.6L. VW, BMW, MB and Audi petrol engines stayed between 1.8 and 2.0L for D segment.....but no compromising the hp performances

fully agree but most of not all these vehicles cannot come to Malaysia because they are mostly EuroV diesel conformance.... Canland proudly have EuroII when Tomyamland and Singaland already have EuroIV. In canland, the merit for pollution goes in different order, diesel last, sangat kotor mentality. hybrid gets free parking (in PJ).

one more thing, those days diesel was cheaper (until 2008) thus higher roadtax (yeah green diesel engines get half) but today diesel equals to ron95 but roadtax? outdated canland can think? eastcanland gave better reason for diesel vehicle ownerships...

agree diesel of similar capacity has lower exhaust emission.

but against a hybrid which switches of engine altogether at speeds below 40kph and stationary, that is ZERO emission which is still unbeatable by diesels.

but the new peug diesel hybrids must be excellent though, combining the best of 2 worlds.

Diesel don't have polluting dead battery to worry about.

I prefers to use my head than follow the crowd. After all, it is my money and not theirs.

you forgotten billions of mobile phone batteries, or laptop, iphone and many more applications that are already around us which pollute as well. and did not contribute anything at all to the environment.

True, but then you have to worry about diesel fumes that cause cancer and belong in the same potentially deadly category as asbestos, arsenic and mustard gas.

Diesels are for those who wants low fuel consumption but still like powerful/torquey drive....anyway, diesel hybrids would be perfect! (in the jam can crawl using full battery mode)

Petrol hybrid are for those who wants low fc but dont bother abt driving dynamic (in jam can crawl using batt mode and in highway can also crawl using low power petrol) ...ie slow driver.. hehehehe smile_wink.gif

sorry petrol hybrid lovers...just joking, cannot help it
