About the only videos my works laptop allows seems to be autocar videos so was having a wee trawl and saw this.

Two very interesting results. 1) Porche 4wd sucks compared to Audi's. Not even close.

2) Jag on winters looked surprisingly good despite the Audi romping away with quattro and summer tyres.

Seems 4WD still owns in the snow even on summers and porche 4wd justs sucks ass everywhere.

Obvioulsy the Jag on winters would brake and corner probably better but purely from a traction standpoint i was surprised by both results.

Any suggetsions as to why the porche 4WD sucked so bad ?????

it also never notes anything about stopping, every 4WD with summers on would run into the back of the jag when he hits his brakes

here's an interesting vid, BMW M3 with winters, vs others with summers (still no braking though.. just amateur stuff)

Evo mag ages ago took a new jag around Bedford autodrome???............anyway jag on summers took ages............then took a Mitsu Evo on standard tyres around.................then fitted winter tyres to the Jag and it been the pants of the Evo!

four times nothing still equals nothing!!!!!......................I've overtaken loads of 4wd vehicles on summers and done a "safe" 50mph in a 60 zone.....and they all struggle to do 35mph!!!

worst to best list i think...

rwd on summers = worst

fwd on summers

4wd on summers

rwd on winters

fwd on winters

4wd on winters = best

Thing is though the audi with 4wd on summers in the video pulled away surprisingly well, better than the RWD jag on winters. I was only really comparing traction off the line as the main surprise was the carrera 4s and how crap it was on the same tyres as the audi. Still puzzles me why 2 such similar cars on near identical tyres both with 4WD can perform so differently.

I did read the EVO mag article your on about and it didnt surprise me a 2wd car on winters beat an AWD car on summers but the autocar video still proves AWD is the best solution for traction off the line or ultimately grip on an incline even on summers as the audi beat the Jag on winters by some margin.

How poor the carrera 4s performed is the mystery as ive experienced quattro drive on summers on snow myself before so i know they work well i just assumed the carrera would be equally as good or at least close but it was miles worse than the audi. Very weird.

Could it be down to the type of 4wd?????.................Is the Audi a permenate 4wd (quattro) and is the porsche a "haldex" type???????

Would be interesting to see same again with traction control on

this is also a good read..... especially as its 2 yeti's identical but for 4WD - 2WD

www.autocar.co.uk/winter-tyres-vs-4WD

only thing the 4WD wins on is traction, and thats worse at the start, and even when it does win its by a small ammount, but the braking is TWICE as good with the winters on, and the cornering/handling is 35% better with winters on...

That audi was amazing its 4wd system is awesome

pah! Call those supercars?

now these are supercars
