Discovery 5 Si6 or sdv6 ??
Anybody tried one compared to the sdv6 disco 5?
It looks to me as though JLR have dropped the model!!!
Only do around 15,000miles/year, mostly short journeys so I’m wondering whether this might be an option??
Some decent deals available on some with low mileage.
With the lack of alternatives the D5 is growing on me!!! Or you I wait for the Defender launch?? Or Merc GLS
Cheers

Si6 got dropped as an engine in Europe, yes. Since I’m running a D3 V8 it seems like JLR did all over again the same they did back then - drop the petrol and go with diesel only. 14 years later the petrol heads are happy with their old vehicles.
Not that I know anything but as the sdv6 engine is the same as in D4 and diesels, even the ones that do not exhibit snapping of cranks, are relatively unpopular... I’d go with petrol.
The GLS (old GL) is a nice yummy mummy car.
Edit: if you need a vehicle today, buy it today. Don’t wait for something that might or might not meet your needs.

It doesn’t make sense does it, manufacturers saying diesel demonisation has caused sales to fall off a cliff yet they no longer sell petrol engines in Europe when they sell them elsewhere.DS3 TDV6 HSE - Silver with Alpaca (old one) Gone

There are a couple of Si6 owners on the Disco5 site, probably best to ask there?

Is the sdv6 (306hp) that they are putting in the D5 now the same as the old sdv6, or different.
I thought it came from the RRS.Still lurking, although moved to the dark side: disco5.co.uk

I completely agree with you. It doesn’t seem to make sense at all. I think the following factors contribute:
- people still want to buy diesels rather than petrol vehicles (or at least more) because of range, price of fuel, they like the tractor sound - I mean, who knows right?
- vehicle emissions; there are limits on average CO2 across all manufactured vehicles that must be met or the manufacturer will be fined with penalties. Selling more petrol vehicles means higher emissions... so it’s a necessary business decision mandated by public policy [1]
Edit: that emissions dictated by public policy (so “sell diesel”) at the same time conflict with public policy of reducing use of diesel everywhere (so “diesel is bad”) is also insane

They do sell petrol engines You can buy an Si4 which is a 300bhp, 400nm, 125mph, 0-60 in 7.3sec, petrol in a D5
The Ford based Si6 was dropped due to the need to meet stringent emissions across the range... the ingenium petrol is more efficient for little lost performance and an ingenium straight 6 shouldn't be far away.

They are all the same engine if 3.0l. Just mapped differently to give different power. But the same twin turbo 3.0l.
The D4 TDV6 3.0l was the same twin turbo engine, but the early D5 TDV6 was the same engine, but with a single turbo.
If I was buying a 3.0l D5, the twin turbo SDV6 is the way to go They don’t seem to be suffering from oil dilution issues like the single turbo units from what I have read
I think Ken on here had a petrol one. Maybe he can advise

Presumably the 6 cylinder will have decent torque figures which seems the biggest problem with that engine only matching a FL2 and a big problem when towing which must be a massive market for the car, but maybe the torque that the V6 diesel has isn’t possible in a petrol?DS3 TDV6 HSE - Silver with Alpaca (old one) Gone

I would think the inline 6 petrol will have several output levels ..equivalent petrols rarely match the torque level of a diesel. Not sure on the direct comparison to the FL2 as that was a different engine but it's rated to tow 3000kg and let's remember that the D3 only had 440nm of torque and that seemed to tow fine.
Trouble is matching the 2021 emission level requirements while going through significant change is not ideal...I'm relatively pleased to see that they seem to be speeding up the production facilities for mass hybrid and electric ....they did miss the boat on that previously for sure.

Freelander 2 could only tow 2000kgs. Hadn’t realised the SDV6 was such a step up in torque tbh.DS3 TDV6 HSE - Silver with Alpaca (old one) Gone
