Why modern 4x4s break the laws of robotics

The modern vehicle is an amazing feat of engineering, and an even more amazing feat of electronic and computing design.  There are sensors everywhere, for everything – wheel speeds, steering wheel angles, all over the engine, even monitors to detect how dark or wet it is.  And soon there’ll be more, fed by data over […]

That’s NOT triple locked!

Don’t confuse centre and cross-axle lockers! There has been a recent trend to refer to vehicles such as the Mercedes-Benz G-Wagen as triple locked, and it’s wrong to do so, even though it’s right. In 4X4 terms, a locker always refers to a cross-axle differential locker. So when we say a vehicle has a rear […]

European Snow and Australian Sand

Experience in one of type driving is a mixed blessing when you come to try something else.  Sometimes the skills carry over, sometimes they need to be unlearned.  And other times two terrains which appear to have lots in common do not.  I’m talking here about European snow, and Aussie sand which are very different, […]

Dirty on dirty

So you own a 4WD and you use it offroad. Often it’ll get dirty in the course of those trips, but when it does, take a few moments clean it.  There is no point driving around for days or even weeks with a dirty 4WD as some misguided badge of honour – you won’t do […]

Pride and Prejudice – Hummer H3 Review

Hummer says it’s like nothing else.  They mean the vehicle, but that also goes for the emotions. Reprint of a roadtest from 2009! The pictures show a car, but it’s not a car, it’s an emotion grenade.  Mentioning you’re driving this car is the roughly equivalent to saying you’ve dumped your partner; people instantly split […]

How modern 4X4s should be designed

I’d like to introduce a new concept to the designers of offroad vehicles.  It’s the same one used to design complex IT systems when the consequences of failure cost a lot of money, loss of reputation or even lives.  It’s called graceful degradation, and it’s not that hard. Let’s say you’re designing a high-volume retail […]
