Thread: FL2 diesel performance

The diesel is fantastic and economical too. Can't recommend it highly enough.

For anything other than a drag race, the TD4 has better performace that the i6.
I have a TD4 but I normally get an i6 loaner when mine is serviced etc. They are a nice motor and have quite good economy but lack grunt IMO.

TD4 is a fantastic engine. If you want a 0-100 machine then the FL2 is not for you regardless of the engine options.

Can I ask why would highway and city driving suggest a petrol when this type of driving is most suitable to a diesel? Only reason I'd choose a petrol if I was doing lots of short trips where the engine did not have a chance to reach operating temperature often.

do not buy a i6,,, its all noise and no go,,, and around town the econ is treble,, on the cars coming in the avg for td4 is about 8-9LPH,, the i6 its 12s

and performance is not that good for a 6,, pretty much all the customers i talk to wish they got the td4

i no of no chip for the td4

Thanks for all your responses.

I was thinking that mainly stop-start city driving suits the i6 more since that's where I noticed the flat spot off idle in the TD4. Once up and running on the highway and for overtaking I suppose there wouldn't be much in it in terms of performance and I suspect that the TD4 would be more economical. The TD4 did feel very strong once it was moving and since I am coming from a diesel pajero maybe the flat spot feels exagerated since as soon as the power kicks in on the TD4 it goes like a rocket when compared with the gradual build up of speed in the pajero.

Sounds like I need to go for another test drive. I'll keep you posted of the outcome.

I've got to take issue with this.

Look at the spec & you'll see the i6 is a 200 kph car. 0-100 kph also leaves the TD4 for dead.

It's a Jekkyl & Hyde car. The power & torque curves are quite peaky, the opposite of the TD4. Around town its easy enough to drive, the jackrabbit throttle response you sometimes get with quick cars isn't there.

But if you need the get-&-up-&-go, the trans will soon drop a gear or two. Overtaking is very easy & very quick. If you really need poke, its there in the top half of the rev range.

Otherwise it potters along quite happily on the highway at say 2000 rpm.

The fuel economy thing is a red herring. One day people will realise fuel is the cheapest part of ownership*. And for the record, I've found the i6 is the same if not cheaper with fuel than the Td4 on the highway. It runs on E10, and around Dubbo, Coonabarrabran etc the E10 can be cheaper than diesel. Mine gets economy in the 9s at 100 kph.

It was the diesel rattle at idle that put me off the Td4 actually. I don't think its good enough.

So for me, the i6 has quite acceptable fuel consumption around town, in Falcon/Commodore territory. With Falcon/Commodore performance.

On the highway its smoother, quieter, costs the same to run, with more poke if you need it.

* Had a client in not so long ago, whinging about the fuel economy of his BMW. Turns out he puts $2000 a year of petrol in it. But its now worth $50,000, bought two years ago for $150,000. Fuel isn't the problem!

i know of no chip for the td4

I do!!!!

I Can retune the current FL2 Diesels.

The good thing with the TD4 FL2 is thats its only $2k more expensive than the i6. And you save on rego because its a 4cyl compared to a 6 (In QLD at least)

I love the rattle and the sound of the turbo spooling up. I was disappointed with the TDv6 in Dad's RRS... its dead quiet!
