Center differential is also where problems are created. If all wheels run independently (as in other cars to have better safety), then four wheel drive does not get you started. That center differential must have what was called positrack. It intentionally causes wheels to fight for control at higher speeds so that four wheel drive can get you started. It also reduces traction and stability on the highway.
Stability control computer is an expensive solution not found in saver cars. Required to monitor those wheels fighting each other. It even applies brakes to one wheel to keep the four wheel drive from doing what is too common - a roll over. That computer is not found and not needed on a 'safer' car. Although GM did try to promote that expensive computer system using expressions such as anti-lock brakes.
All-wheel drive only provides one useful function - to get you started. It does not provide more safety once moving and does not provide better vehicle stability. It means braking may not be as good. Many four wheel drives add that expensive stability control computer and other expensive hardware because four wheel drive can even mean less effective braking. Because so many all-wheel drive vehicles flip or more easily lose control on highways.
Spend more to have less safety? The advertising forgets to mention why these vehicles are more dangerous to people inside and outside. It contradicts to requirements defined by Lola Bunny.
The car guys noted a better vehicles for Alaska. The caller was considering a Jeep. A vehicles better described as barbaric; is that technically obsolete. They recommended something more reliable and better for Alaska's roads - a Subaru. But that is not the relevant venue. Relevant are facts introduced in every April issue of Consumer Reports.
