Four Wheel Drives myths and facts

Tired of justifying your choice of car to every sniping sedan driver?

Help is at hand. The Australian Four Wheel Drive Council has put out a list of facts about 4x4s which explodes some of the most common myths.

Take the bloke in the pub who is always quoting accident statistics. Chances are he's quoting numbers from the US, where what they call SUVs are completely different and where only 11 states have enforceable seat-belt laws.

In actual fact, the latest figures from the Australian Transport Safety Bureau tell us that, unlike the US, the accident rate for 4x4s and sedans is almost identical in Australia. And the most recent NSW RTA statistics tell us that in country driving, sedans are nearly twice as likely as four-wheel drivers are to be involved in single vehicle accidents.

Then there are the people who tell you that 4x4s are more likely to roll than other cars because their center of gravity is too high. While the center of gravity is a little higher in a 4x4 than in a sedan, it is only the difference made by the larger tyres.

Any engineer will tell you why: it's to do with how drive trains and how universal joints have to work (this does not take into account highly lifted competition vehicles).

In order of rollover ease (highest to lowest) you could classify vehicles: B-Double, Semi Trailer, Heavy Truck, Bus, Light Truck/Delivery Van, Heavy 4WD, People Mover, Light 4WD, Sedan, Sports Car, Go Kart.

You often hear people moaning that 4x4s take up too much parking space. In fact, if you compare a Nissan Patrol, for example, with-say-a Chrysler Voyager, which is often touted as a replacement model for the 4x4, the Chrysler is longer, wider and higher than the Patrol. And as for the people who tell you it is impossible to see out of the back of a 4x4, they obviously haven't read the report of the survey conducted by IAG and the NRMA, which found that “no car type is inherently better than any other. There are good 4WDs and bad sedans; in fact, the lowest rated car was a sedan, not a 4WD”.

Traffic studies also show that 4x4s are under represented in accidents, relative to the number on the road. Clearly a heavier car is more likely to hurt somebody more than, say, a motorcycle, but even so, sedans were involved in 66 per cent of pedestrian fatalities compared with 15 per cent for utilities, trucks and 4x4s.

As for the gas guzzling theory, studies have shown that, around the city, where average speeds are less than 30kmh and air resistance is negligible, a large 4WD will use exactly the same amount as fuel as any other vehicle of the same weigh: it's just a matter of physics.

So, if someone calls your pride and joy a Toorak Tractor, you'll be able drive straight through their arguments!
