4wd. ugh. numbs the turn in, adds understeer, and then gets the car floating into a 4wd drift on exit; you only really love the 4wd when you get on the loud pedal on exit, and you feel all four tires bite, or are in the rain. i'd rather have any car be 2 wd only; it's easier to setup, and is lighter. more traditional, but that's not bad. re: viper. it's actually not a bad handling car, but it's just really really easy to oversteer. does need some setup (sus & previous generation brakes are very weak), but it's a great track car in the right hands. the new viper is much improved in the brakes/sus department, but still looks like a colt inside with like fit & finish. last time at laguna seca, an instructor had a hennessey viper (bolt on's, head work, ap racing brakes, etc.) and he got passed like he was standing still by a bone stock GT 2 on slicks. the viper was on wider rubber, too. | ||

While the Enzo and F1 Ga are Fiats! Sv is fine in the rain, although i admit i dont drive it in the rain often. | ||

But the Enzo and the F1 GA are Ferraris, not tractors. <ducking> What other reason but adding traction for the power would Lambo have to eat the drivetrain losses? How's the Sv in the wet? Maybe car makers now have to make the owner feel like a better driver than (s)he is? | ||

The Enzo and F1 GA seem to get by without it. | ||

I have a 2 wheel drive Sv Lambo that is the most powerful and lightest Diablo made, and it has no problems with wheelspin. Autoweek just had a story on tv, showing sketches of the new Ferrari 456 replacement, and they said they are considering 4 wheel drive. | ||

"Why does Lambo use it?" Big honkin' engines and suspension that can't get the power to two wheels without spinning 'em.  | ||

Well it seems to make sences for P-cars and Audi since they are daily drivers in all weather. Why does Lambo use it? Past and present cars. No one takes Lambo out on rainy day? | ||

AWD also adds more drivetrain losses, so less horsepower reaches the tires. But you distribute the torque so your tires need less traction to get power down. Torque to the steering tires alters the handling a bit, too, depending on the front/rear power split. A different driving style is required to push near the limits (just like FWD vs RWD). On poor traction surfaces, AWD has higher limits. But things can get very ugly very quickly once you pass those limits. But you do get to play with handbrake turns. (In the snow, that is -- most handbrakes won't stand up to dry traction games). | ||

When Porsche ran the 961 at Le Mans many moons ago (the race version of the 4 wheel drive 959) on the dry track they kept reducing the drive split front rear till they finished with something like 90-95% of the drive to the rear wheels. I remember (because it's my favourite Porsche) it finished the race and they decided the weight penalty wasn't worth it unless it rained and that wasn't often enough. And I think it was a little harder on the tyres. Alfa ran 4 wheel drive in the DTM but the rules due weight worked in their favour so that doesn't really count. Correct me as necessary. | ||

Also AWD adds a couple hundred lbs of weight. | ||

Advantages- AWD is a little easier to launch quicker due to better traction... More forgiving in bad weather.. Disadvantages- harder to power oversteer with on the track, more complicated and heavier.. Odd twitching and funny chracteristics when driven at the limit... I rode with a factory A4 race driver in a Carrera 4 years ago who couldn't articulate the sensation at the limit, but was happy to demonstrate the experience on a public road... Not recommended if you treasure your life... That's all I know | ||

A 4-wheel drive should be better in the rain or snow.........allows one to drive all year long, in the snow belt......if one so chooses. | ||

Mark, can't say about Ferrari, but I also own a 2001 C4 Porsche that is AWD. What a great GT car. I haven't a clue what this car would be like on the track because I don't drive that close to the limit on the street. But out in the real world, Porsche's AWD works great. Plus, Vipers are great in a straight line. Damn curves do you in every time. And finally, the TT is one hell of a car. I'd love to see Ferrari build something similar. | ||

The 408 program used 4 wheel drive. | ||

Just reading 0-100-0 test in Road & Track. Viper vs. 911 turbo 4 wheel drive. Viper has 50 more Hp but 911 wins. Never thought about it before, but I know Lambo uses it also. What are advantages and disadvantages of 4 wheel drive and has Ferrari ever used it? |
