Thats good to know.
What is the engine breaking like on the D240 Tim? I've haven't had a chance to test drive the diesel, but hoping it does have good engine breaking when manually held in gear. |

Now the HDC operates much more quietly than in my previous Land Rover cars it’s hard to tell when HDC has taken over unless you disable it. I’ve only done one seriously steep down slope and not used the HDC and it was OK but nothing to match my TDi300. More practice might be required! Commandshift control (manual gear shifting) of the new Defender off-road would be much nicer if LR had seen fit to add paddle shifters to the gearbox system, it isn’t helpful to have to take a hand off the steering wheel to do a manual gear shift that in other LR models can be done with a finger on a paddle.

Surely you just knock it into manual (“sport”) mode and then you can hold it in a specific gear in low range to use the engine braking, same as on an old Defender?
I know it’s an auto but I would presume that it would be able to lock up to achieve this. |

Even in manual shift the computer will decide if you should have engine braking or HDC unless you disable the HDC by its on/off switch which is how I prefer to drive it, HDC when I want it not when the computer thinks it’s needed. I read somewhere recently though that with the new software in Defender that even if you switch off the HDC when using one of the TR programs it runs in the background waiting to cut in without being asked........ similar to the stability controls on the sporty Mercs, even when you switch them off they aren’t fully off and will still intervene. You don’t have to use the programs and can still drive it old Defender style with just the low ratios and centre diff and HDC turned off, which is my preferred setting!
