Is that redlining though the gears or in top?
I though I had.
Find me dyno plots or at least the rpm those peak torque and power figures are at + redline rpm. Gear ratios, Final drive ratio, Tyre sizes. Or at least mph/1000rpm in top for each. Mph/1000rpm for lower gears will permit cascades to be drawn showing optimum gear changes and show how to get the Capri to deliver a spanking to the TDCi (hint power not torque).
For full analysis to max speed in top I also need Cd and frontal area, or top speed (not speedo indicated).
I've got to admit the 2.0TDCi is at it's best in top gear between
50-70mph. As for the 2.2TDCi, I have to be in 4th to even think about it at 60-70mph. It's why Diesels suit so many people that like to drive at moderate/low rpm. The fact that Diesels become so nasty at high rpm just reinforces the fear of the redline but it's holding revs up around peak power that gives the best acceleration performances that are quoted by makers and in the press. Unfortunately the performance below peak torque of diesels is very very poor. If you feel the surge as it comes up to the peak torque you are losing a lot of performance, you should have changed down before mashing the pedal. A diesel above peak torque is only down a little bit on max acceleration by selecting the wrong gear (too high), below it loses a huge margin.Sadly all the comments about Diesels having "narrow power bands" makes me think people are feeling that pathetic torque surge. A good diesel truck doesn't have a "power band", it has a power line, max power is constant over a 1500 rpm band, like 3000 to 4500rpm, while peak torque is way down at 1500rpm.
