LR-SDV8 4.4 Litre Diesel Engine

Designed exclusively for the Range Rover, the LR-SDV8 diesel engine offers a powerful, effortless driving experience that’s rich in torque - 700Nm, delivering 339hp of power, whilst achieving 229g/km of C0₂. Parallel sequential turbocharging achieves consistent power and performance throughout the rev range; and the eight-speed automatic transmission is smooth and responsive, offering compelling driving refinement.

Diesel Particulate Filter is standard.

The TDV8:

"only" 309 hp of power.

Is it simply a different map LR have used for the power increase - or is something more complex?

Interestingly JE list the same power output for both engines when remapped by them - essentially from what I am told its the same engine just tweaked and re-badged 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

As above but with the lower weight the pre-prod i drove at LRE was rated at the 309bhp and still shifted very nicely indeed! FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Not 100% but does the SDV8 not have different Turbo's ?

i spoke to JE this week they have no real figures for the SDv8 as they have not done one in the UK ! i was told Far to many gone...

Very strange, the power outputs and all the details including Power & Torque curves were on their website, I'll have a look I know I have previously posted a link to the page on another thread. From memory the cost was listed at around £800 and there was some debate as to why the cost was around double that for a remap on another LR vehicle.

edit,

just checked their website has been updated and all details removed. There WERE figures for all recent Range Rover Diesel engines listed - now I can find nothing very odd listing power outputs if you haven't even done one.

I am going to contact them later when I get a few minutes as they have previously done vehicles for me and want a new vehicle doing. Not entering into anything without an indication of hard figures! 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

so if I asked my local dealer for the SDV8 map for my TDV8 - would it be a no, yes but there is a charge, or yes and free of charge?

Most main agents I think would laugh, as it wasn't offered on the std vehicle so could compromise warranty etc and their dealership status. However,, not mentioning any names I was offered a remap on a brand new vehicle from a LR Main agent! from memory I think the sales person said it was an Autologic power upgrade. I went to JE in the end 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

How did the remap from JE work out. I was considering this option but the 4.4 TDV8 is a powerful unit already and I wondered if the improvement was worth the £800 approx. cost. Agueroooooooooo. 93-20
I swear you will never see anything like this ever again....watch it..drink it in.

Not had the 4.4 done yet, still considering myself if it is worth £800,

£350 to £400 and I wouldn't hesitate but £800 that's a set of tyres! 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

Ok sorry I misunderstood when you said you went to JE I thought you meant the FFRR. If you do speak to them will you keep us informed with what they say. It does seem strange the latest info has gone off their website. Agueroooooooooo. 93-20
I swear you will never see anything like this ever again....watch it..drink it in.

It was an earlier FFRR of mine, I paid £380ish from memory, I went for it as JE had just published figures for their TDV8 3.6 and there was also a journalists review of a JE mapped TDV8 3.6 trouncing a 4.2 Supercharged in the 0-60 dash. 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

The 4.4 has plenty poke as it is spending £800 for a re-map just isn't worth it as Vogue says a new set of tyres....no brainer really
