They are both nice engines and the V6 is silky smooth and economical but, in comparison to the V8, the V6 has an amount of lag that probably surprise you when you first pull out of a junction (especially if you’re used to sequential turbochargers) and the V8 corners a fair bit flatter than the ‘6. While I don’t want to over state it, the long term durability of the V6’s crankshaft may also be a slight cause for concern.

Went from a 3.0 TDV6 to a 5.0SC and love both engines. The torque is similar to the SC, so great for normal driving. The SC is a bit of a hooligan when revved. I'd definitely have another 3.0 again as it's very smooth, comparable to the SC at low revs. Didn't really notice the lag that's been mentioned. With short commutes, I got around 28mpg in 3.0, now getting 20 in SC. On a run it's great though, 40+ mpg.

I came from the SDV6 (sequential turbo) D4, to try the virtually identical TDV6 (but with single turbo) Full Fat. It was probably the step straight from one to the other that made the low end lag apparent.

Don't know about the V8 4.4, but the TDV6 is a great engine, quick and smooth and in the MY18 FF has none of the acceleration lag that the D4 had (especially at junctions).

Does the tdv6 require a timing belt change at $100,000 miles? ______________________________

Hi if it falls in the range of vehicles covered by JLRP00100 Oil Dilution Issue (16 MY onwards I think) do not even consider the TDV6, yes it returns 40-42 mpg on a constant run and is cheaper to insure and tax BUT ..........

It is a point, the 2016 D4 SDV6 had to have an additional, unscheduled, oil change in the year that I had it. Fortunately, I had a good dealer that sorted the cost out with LR. |

Of these two, the 4.4 would be my choice. First, there seem more reports of problems with the TDV6 (search on here and also on Disco and RR Sport forums). The risk is probably small, but is it worth taking? Secondly, dealer comment to me was that the TDV6 was about the same in performance as the 322 TDV8. The SDV8 in the 405 is a distinct step up from the 4.4 TDV8 322. Overtaking in sport mode put a smile on my face anyway. Finally, I'd fear that if I got a TDV6 I'd think I could have done better and regret it. Going by recent press reports V8 engines won't be available at all in the RR from about 2020, I'd want to have one while I can.

It depends what sort of driver you are, what you expect from a car and how many miles you drive. If you have any doubt which you already have - Do yourself a favour - spend a day driving the V8 and then drive the V6

As others have said, drive both and make your choice, i drove a 3.0 13 plate and it was a nice relaxed drive. I haven't driven a SDV8 but if its better than my 2011 4.4 TDV8 then it must be a real gem. I had mine remapped but it wouldn't be a Porsche beater and I'm an awesome driver, F1 material!!!! Seriously, its a range rover and for me it should be effortless with a wall of torque which the V8 has. 2015 4.4 AB

We're not so old and enjoy 'pooteling' about in the 3.0 There are no bad models of the L405. Options and decisions! |

Is it acceptable to be pooteling about in an SDV8? Or is that just a terrible waste?! |
