Even though you are happy to pay a bit more Land Rover ain't, soon manufacturers will be heavily penalised for every "dirty" car they sell.

It's about fuel economy, sales and emissions. Less weight = less fuel = lower emissions = lower Tax Band = more sales. The new RRS the low Box is optional along with Disco, I find it useful, but many of the buyers the only off road they see is on the pavement.

I believe there is always a small amount of drive to the rear but most is to the fronts. 21MY Defender 90 S 3.0 D200 |

Freelander is predominantly front wheel drive. When you move off from stationary it is about 90% front drive, at a constant speed in a straight line it is about 70% front drive. Only when the car detects the need for equal torque at the rear does it switch to a 50/50 split. It takes about 15 millionths of a second for it to switch the drive ratio. |

Active driveline is really to get the emissions down for the Si4 at the moment. 21MY Defender 90 S 3.0 D200 |

Wrong way round - there's more drive to the rear when moving off from rest in order to minimise the risk of wheelspin, then as the speed increases (and torque at the wheels decreases) the drive to the rear is reduced to improve fuel consumption. The following is from the workshop manual, referring to the Active On-Demand Coupling (i.e. Haldex):
Although this is phrased in terms of torque transfer, not percentage, the pre-charge means that in practice drive will be 50/50 when moving off from rest, then gradually transfer to 90%-ish front drive at speed. (N.B. The torque figures referred to above are torque at the coupling, not engine torque - i.e. engine torque is modified by gearing, which is why the transfer figures are higher than maximum engine torque.) |

You're not - I wholeheartedly agree! It's not just part time AWD either - for years before getting the FL2 I had 4x4s with low range, and in the FL2 I really miss it. I love everything else about the FL2, but I really wish it had low range. Not so much for off-road use, but I used to find it really useful day-to-day for low speed manoeuvering, etc. I found myself using it a lot more than you'd think. That said, I also understand the economic and social factors which are driving Land Rover, and from a business perspective it's hard to argue with what they're doing, even if, for me, the cars are lessened as a result. |

The new ZF 9 speed gearbox going into the Evoque has a 1st gear that is to all intents a low range gear, it also has what are effectively overdrive gears at the top end as well resulting in about a 10% improvement in fuel economy and 11% reduction in CO2 levels.

That's pretty much what we were told at Halewood that the 9 speed would be fitted, first gear sounds like it will be a manual selection as it is very low, in normal use the box will ignore it and set off in 2/3 gear. |

Yeah, but that's an auto! What about a proper manual with low range? Or at least a lower first and reverse. |
