Scotland 2014 Freelander 2 TD4_e Dynamic Manual Fuji White
Active Driveline System

What are Land Rover playing at "wheel drive system which operates in front-wheel drive only during steady-state driving at speeds above 22 mph (35 km/h)" Evil or Very Mad The new disco now comes with an optional low box Rolling with laughter what are these clowns playing at!!! How long till the Freelander comes with active driveline? Is it just me or is anyone else thinking the same thing? So what if it saves you fuel who buys a Land Rover and has fuel economy in mind? The main thing Land Rover are well known for globally is the permanent all wheel drive system. I would happily pay a bit more road tax and use more fuel. Even in dry weather all wheel drives makes a massive difference! In Scotland the ED4 Evoque and ED4 Freelander 2 have failed! Will the Active Driveline System replace the ED4? I cant be the only one who cringes about Land Rover and part time all wheel drive surely.......... Big Cry MY14 Kahn Converted Dynamic - Fuji White Ebony/Pimento Interior

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.

I'm a die hard Landy fan, but things must change, LR is a business and have to keep up with their rivals. It's not such a big deal series Land Rovers came with selectable 4WD and we drive a LR with no low range, when the Freelander first appeared it caused a bit of a stir among the die hard fans.

Plus it's only available on the Si4 Evoque at the moment, though I do think its a good system it can change in 300 milliseconds when it detects slip, our Freelanders don't drive all the time with a 50/50 split they are front wheel drive biased. 21MY Defender 90 S 3.0 D200

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.
It has been said that the reason the Freelander comes without a spare wheel is to get it down to a lower Tax Band, haven't a clue if it is true. But the comment you made about LR drivers who buys a land Rover for fuel economy, you would be surprised the amount who come on here expecting 50 to the gallon.
Iirc the Freelander is front wheel drive, with the rears basically on standby. p****d off with a Digital Keyboard Warrior

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.

Land Rover say the Freelander is 70:30 and when at a cruising speed it is 90:10 MY14 Kahn Converted Dynamic - Fuji White Ebony/Pimento Interior

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):

Quote:

Vehicles fitted with Terrain Response also add further benefits by varying the level of pre-charge to deliver optimum traction over a range of different terrain surfaces. The level of pre-charge is varied depending on the particular terrain response mode, for example:
    Terrain response in 'Special Programs Off' mode as common with vehicles without terrain response, the coupling is programmed to transmit 500 Nm 369 lb ft of torque on Generation 3 couplings and 1500 Nm (1106 lb ft) of torque on Generation 4 couplings to the rear axle when the vehicle moves from rest in a straight line. This strategy minimizes traction loss from a standing-start regardless of the terrain. When the vehicle accelerates the pressure in the coupling is decreased to improve fuel economy.

    The ability to sense the steering angle allows the coupling to be programmed to provide no torque transfer through the coupling. This prevents the coupling locking when the vehicle is maneuvring at low speeds and acute steering angles.

    In 'Grass / Gravel / Snow' mode the coupling is programmed to maintain its pre-charge state until much higher speeds are obtained. The same applies even if the vehicle is traveling at low speeds and acute steering angles, as traction takes precedence over coupling lock-up on low-friction surfaces.



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.

England 2011 Freelander 2 TD4 XS Manual Baltic Blue

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.
I'm pretty sure the replacement for the Freelander will be offered with the 9 speed box, as will other vehicles in the range.

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.
