We nicknamed our 300Tdi "slug" - because that is what it feels like after getting out of the 4BD1T.

Why 200/300 Tdi enthusiasts love them so much ??

In a lightly loaded vehicle, for general driving (which is the bulk of what most people do), the 300tdi is a great engine. Simple, reliable, economical etc.

Fully loaded or towing, the 300tdi is definitely a much lesser engine than a turbo'd 4bd1.
As a friend of mine says, you cant appreciate them from a 5 min drive in someone else's. Thats usually about all we allow a non-owner to have

Did you ever consider the 3.0 litre V6 DMAX Isuzu engine? They were also used in the Saab 9.5. you should be able to find them easily in Europe. They pump out 125Kw, 25 better than the 4BD1-T

the reality is, that people are very rarely going to bad mouth something they have bought themselves, as this would seem a contridiction in judgement.......being that the defender here has only ever come out with one engine option (depending on the year either: 200tdi, 300tdi, TD5 or puma), and it being beyond most peoples ability (either one or a combination of, Time, money, skill) to do a successful engine swap.....

for me an engine swap has to have 100% reliablity (equal to the OEM) and no niggling problems day to day.....an engine and gearbox relation is very important and many come unstuck at this point.

I chose the 2.8tgv, as it was ment to be bolt in, used many existing components and would be very easy with regards to legal side of things. In hindsite, If i were to do it again I would go for the Isuzu with a Isuzu gearbox..BUT, I would have to be able to source an engine/gearbox as quickly and as good as I did, and have the install done in the same time frame as I did, owing to the fact I only have 1 vehicle and I need it for work.....Not to many people plan ahead for a total engine failure.

IMO the 300tdi is an underpowerd under engineered absolute just scraping by type of engine give the type of vehicle it is going into....followed by a close 2nd with the R380 (its only saving grace the fact it has an internal gear pump)

and once again LR have fallen further behind the curve with another under sized, under powered engine but thats a moot point as the defender has been going backwards since release....

It's all very well for us to gripe about pathetically small engines in Land Rover Defender, however Land Rover have to build a product based in the regulations of the EU.

Until Land Rover start building vehicles outside the EU, our hope for an efficient engine of a size that will cope with the distances and loads, (both carried in and towed) we have in Australia and dare I say both Africa and most of Asia, we will never get a suitably sized engine option.

The fact that a lot of us are retrofitting Isuzu engines, is because in Australia the 4BD1 was the only diesel engine option available in the original Aussie spec 110. In short the 4BD1 is an OEM fitting.

Sorry but that is a load of rot. The Iveco massif/Santana PS110(now no more unfortunately), G-wagen, Touareg and (current)RR/Disco4 are all made in the EU, yet they have decent size/output engines.

Btw - just as LR offered the Disco 1 with the 2.0 mpi engine in some countries, they could have manufactured a larger capacity defender variant.

O.K Lets look at the situation.

The EU Commission rules require manufacturers to reduce CO2 emissions to an average of 130g/Km by 2012.

If you are Mercedes you can sell a few McLaren SLR's with CO2 specs of 236g/Km and a few G-Wagens by selling a lot of A Class Mercedes that may come in under the 130g/Km (but don't).

The same with IVECO, they can sell a lot of FIAT 500s against their IVECO Mastiffs.

However if you are Jaguar Land Rover, you don't have an A Class that you can sell a lot of to get your whole of range average down, so you have to reduce the size of your punyPuma powered Defender from 2.4 litre to 2.2 litre. Maybe that's what the 2WD Evoque is all about!

Your information is in error:

THE European parliament this week voted to adopt a 175g/km carbon dioxide emissions target by 2017 for light commercial vehicles up to 3.5 tonnes gross vehicle mass.

The target has a phase-in period starting from 2014, with 70 per cent, 75 per cent and 80 per cent of each manufacturer’s fleet complying in 2014-16 respectively, and 100 per cent from 2017 onwards.

Manufacturers registering fewer than 22,000 new vehicles a year can apply for an exemption.

A long-term target of 147g/km has also been set, although this is subject to review in 2013.

The commercial vehicle target is less stringent than the 130g/km limit being phased in for passenger cars in Europe by 2012

NOTE - there is no mandatory/binding CO2 limit at present, just a "voluntary" target. The first binding limit will be the passenger vehicle limit for 2012.

Most defenders will fit into the commercial vehicle limit, which hasn't yet come into being.

However your original comment was in response to people griping about the Tdi. There were no such regulations around when the Tdi came into effect.

In short, there is no reason LR could not produce a defender with say a 3.0L TD fopr non-eu countries, both now or in the past.
