My 07 Rabbit at BAC Rallycross #2 2018-2019 (I was having A LOT more fun than I look...) - Kevin Doubleday © FWD cars don't win the WRC anymore and they haven't in decades. In fact, all two wheel drive (2WD) cars have been rendered entirely obsolete on the world stage by the original legendary Audi Quattro. That's because 4 driven wheels are obviously far better at putting power down than just 2 and when you are on a loose surface such as mud, gravel, or snow, traction is in SERIOUS short supply. Thankfully, I'm not on the world rally stage or competing for the world title, so I'm happy with my little FWD rallycross car (for now anyway...). I have already been to one event this season (which is my first rallycross season) in this car. You can read more about it here where I nearly caught air going over one of the bumps . Last time was on gravel, though. This time, it was a snow covered course and what I didn't know was that snow wasn't covering gravel
A few weeks ago, I made a post explaining mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky
