Actually, You can get the Jeep Liberty with 2.8 Common Rail Diesel & 6 speed manual or 4spd auto transmission. IMHO its a cracking engine & I would much prefer it to the 3.7L V6 Petrol Liberty I have now.

[From Codprawn]
I have driven the X5 several times and was very impressed BUT what is it trying to be? It is too high to be a sports car but there is no way it could ever be called an offroader!!! [/QUOTE]
It's actually fairly poor at being both of those things. but as a long distance on road towing tool, only the lastest Range Rovers come close. If I didn't tow with it and occasionally need four wheel drive, I'd go for a 5 series diesel estate like a shot. When we chuck the kids in and drag the boat 100miles to the sis's in Devon, the X5 is a great bit of kit. Pure off-roader? Poor.

It is all down to driving technique and it is suprising how many people just leave an auto in D and let it get on with it - they never bother to change down to save the brakes either!!!
THEY have a lot to answer for - the swine!

Quick! Let's get over to Boatmad. THEY aren't on there at the moment.

What do some of you mean when you say people dont drive automatics wrong or they have to down shift while braking? Most automatics I have driven have the stick go either Park, Reverse, Nuetral, or Drive. Some with shiftronic (Shifting with no clutch) But if you just put the car in Drive and go are you guys saying while braking change to nuetral? (I kno another stupid question but im just a little confused about it) Thanks

I have driven loads of cars with Yank auto boxes and all the ones I have driven also had numbers - on a 3 speed auto you would have P N D 2 1 and on a 4sp it would be P N D 3 2 1.

Basically the numbers are the other gears - D is always the highest or overdrive.

You can change down for better engine braking - say going downhill or coming up to a junction - just pull the stick back. Don't go too low though - not good to go into 1 at 60mph!!! Do NOT go into neutral for braking - no help from the engine at all then!!!

You can also put it into 1 to start off and then change up again like a manual without a clutch.

The Yanks build some tough old auto boxes - the European boxes may be more sophisticated but theYank ones are pretty much unburstable - well the GM and Chrysler ones anyway.

Why use a very expensive engine to do the job of a cheap set of brake pads?

Because on long downhills you can get brake fade which is pretty scary!!! Obviously you don't want to have the engine screaming away at 5000rpm all the time but especially with a diesel you get pretty good engine braking without needing to over rev.

Wonder why they have hills with signs telling lorries to use low gear???

Strangely, none of the cars seems to have had a reverse gear..........

Probably because it's good practice to be in the correct gear for a given (low)speed for descending hills.

I'll inform my instructors at the Emergency Services driving college that the Roadcraft driving system that Police/Fire/Ambulance use is flawed.
