Is Diesel Inferior?

Personally, I've found it harder to get book figures from diesels.

Interesting. Maybe it's the fact that petrols encourage me to drive them a bit harder. The mondeo was nearly band on book, the Saab...erm, wasn't :)

Not sure what I'm getting out the accord, could be 4mpg for all i know,have given up measuring it or caring because of the mileage I'm doing now!
 
I have an X6 which has BMW’s 35D 6 cylinder twin-turbocharger (282 hp/430 lb-ft) engine. It’s my first owned diesel and I love the power and delivery. It’s on par if not better than my last petrol three litre straight six engine. This engine has come a long way and shows what can be achieved with diesel.
 
When i was doing the miles my 330d was superior.
Now im doing next to no miles (car has been sat on drive and not moved in 3 weeks!) its very very inferior!

But is a standard 2 litre 4 pot petrol any better? Have you driven a 123d?

Cant say i have driven one but even without doing so i can tell you i hate it because its everything i hate in 4 pot diesel engined cars.

Yea a 4 pot petrol isnt the last word in refinement but at least it dosent sound like a diesel or vibrate for no great downside that i can see unless you are doing big miles.

My own car is smack on book figures.

Would still love to hear if people are actually getting 40 combined from the new 330i. Sounds incredible if it actually returns that!
 
Is it also safe to say that although cars are getting more efficient (larger MPG), manufactures are also exaggerating the achievable number further these days? You could get book figures in the past (as fox points out every other day ;)) but it’s just not realistically possible now?

Sadly time is running out for those of us who like an engine we cant hear when sitting at the traffic lights, who enjoy chasing the redline and who dont like vibrating gearsticks. Dont argue, they all do it.

Disagree here, more and more petrol stations are stocking LPG all the time and I can see manufacturers starting to sell cars designed for LPG on mass within the next decade. Once this takes off we will have cars with the power of petrol and the fuel cost of Diesel thus making Diesel itself irrelevant.

If LPG was going to take off it surely would have by now

Personally I think petrol engines are going to go small displacement with high pressure turbo, it looks like most manufacturers are doing it, VAG 1.4 TFSI, Fiats effort, and now Honda with the mention of them going the FI route after being well known for NA engines. The BMW approach is an odd one out though.

Where have Honda mentioned turbo?

HCCI is there target along with AVTEC as far as I'm aware.

SEMA CR-Z Concept, I know what the predictable response will be to that but all cars start out as a concept and hopefully that is what will happen

A-VTEC was due for release on the 2008 Accord and theres been no mention of any kind since and the Accord stayed with K series engines. Maybe they will but they dont seem very up front with the info compared to IMA

I dont know what HCCI is?
