:embarrest: I should have checked that. There is quite a power difference between the 120d and 123d - I guess they couldn't have the 120d 150bhp in the model name.
The Rover 200 did not have a 0 litre engine - an interesting side point
Sequential turbocharging is a very effective way of getting enormous power and torque outputs from smallish engines whilst minimising or totally eliminiating the traditional lag problems.
This is why diesel engines are finding their way into true performance cars now.
I'll be a believer when I see Le Mans won and dominated by a Diesel.
(Don't give me the "this has already happened" line. - Like the moon landing which was faked and all these daft people that think we live on a globe I will not be taken in by this shallow attempt to make a petrol engine sound like a diesel using some speakers and a few bits of plastic to cover up the petrol engine.
Anyone of the opinion that the twin-towers tragedy in 2001 was set up by the US Government in order to distract attention from the dreadful state of the domestic economy?
The changeover is quite progressive with the smaller turbo running out of pressure as the larger one gets into its stride.
Afterall, the whole idea is to mask the effects of turbo lag and spool up time rather than just move it from 1500rpm to 2500rpm and create a great big chasm in the torque curve. That could be bloody dangerous halfway past a lorry.
The 120d has a very linear torque delivery. The VAG cars tend to be quite agressive lower in the revs. The BMW tends to be quite sedate but lasts longer.
